  • Right-Time Retail Part 2

What good is an immediate stock-out notification if the supply chain can’t react until tomorrow? Since being formed in 2006, Oracle Retail has been not only adding more integrations between systems, but also modernizing integrations for appropriate speed. Notice I tossed in the word “appropriate.” Not everything needs to be real-time – again, we’re talking about Right-Time Retail. The speed of data capture, analysis, and execution must be synchronized or you’re wasting effort. Unfortunately, there isn’t an enterprise-wide dial that you can crank-up for your estate. You’ll need to improve things piecemeal, with people and processes as limiting factors while choosing the appropriate types of integrations. There are three integration styles we see in the retail industry. First is batch. I know, the word “batch” just sounds slow, but this pattern is less about velocity and more about volume. When there are large amounts of data to be moved, you’ll want to use batch processes. Our technology of choice here is Oracle Data Integrator (ODI), which provides a fast version of Extract-Transform-Load (ETL). Instead of the three-step process, the load and transform steps are combined to save time. ODI is a key technology for moving data into Retail Analytics where we can apply science. Performing analytics on each sale as it occurs doesn’t make any sense, so we batch up a statistically significant amount and submit all at once. The second style is fire-and-forget. For some types of data, we want the data to arrive ASAP but immediacy is not necessary. Speed is less important than guaranteed delivery, so we use message-oriented middleware available in both Weblogic and the Oracle database. For example, Point-of-Service transactions are queued for delivery to Central Office at corporate. If the network is offline, those transactions remain in the queue and will be delivered when the network returns. Transactions cannot be lost and they must be delivered in order. (Ever tried processing a return before the sale?) To enhance the standard queues, we offer the Retail Integration Bus (RIB) to help the management and monitoring of fire-and-forget messaging in the enterprise. The third style is request-response and is most commonly implemented as Web services. This is a synchronous message where the sender waits for a response. In this situation, the volume of data is small, guaranteed delivery is not necessary, but speed is very important. Examples include the website checking inventory, a price lookup, or processing a credit card authorization. The Oracle Service Bus (OSB) typically handles the routing of such messages, and we’ve enhanced its abilities with the Retail Service Backbone (RSB). To better understand these integration patterns and where they apply within the retail enterprise, we’re providing the Retail Reference Library (RRL) at no charge to Oracle Retail customers. The library is composed of a large number of industry business processes, including those necessary to support Commerce Anywhere, as well as detailed architectural diagrams. These diagrams allow implementers to understand the systems involved in integrations and the specific data payloads. Furthermore, with our upcoming release we’ll be providing a new tool called the Retail Integration Console (RIC) that allows IT to monitor and manage integrations from a single point. Using RIC, retailers can quickly discern where integration activity is occurring, volume statistics, average response times, and errors. The dashboards provide the ability to dive down into the architecture documentation to gather information all the way down to the specific payload. Retailers that want real-time integrations will also need real-time monitoring of those integrations to ensure service-level agreements are maintained. Part 3 looks at marketing.

  • Using EUSM to manage EUS mappings in OUD

    - by Sylvain Duloutre
    EUSM is a command line tool that can be used to manage the EUS settings starting with the 11.1 release of Oracle. In the 11.1 release the tool is not yet documented in the Oracle EUS documentation, but this is planned for a coming release. The same commands used by EUSM can be performed from the Database Console GUI or from Grid Control*. For more details, search for the document ID 1085065.1 on OTN. The examples below don't include all the EUSM options, only the options that are used by EUS. EUSM is user friendly and intuitive. Typing eusm help <option> lists the parameters to be used for any of the available options. Here are the options related to connectivity with OUD : ldap_host="gnb.fr.oracle.com" - name of the OUD server. ldap_port=1389 - nonSSL (SASL) port used for OUD connections.  ldap_user_dn="cn=directory manager" - OUD administrator nameldap_user_password="welcome1" - OUD administrator password Find below common commands: To List Enterprise roles in OUD eusm listEnterpriseRoles domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn=<oud administrator> ldap_user_password=<oud admin password> To List Mappings eusm listMappings domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn=<oud admin> ldap_user_password=<oud admin password> To List Enterprise Role Info eusm listEnterpriseRoleInfo enterprise_role=<rdn of enterprise role> domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Create Enterprise Role eusm createRole enterprise_role=<rdn of the enterprise role> domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Create User-Schema Mapping eusm createMapping database_name=<SID of target database> realm_dn="<realm>" map_type=<ENTRY/SUBTREE> map_dn="<dn of enterprise user>" schema="<name of the shared schema>" ldap_host=<oud hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password="<oud admin password>" To Create Proxy Permission eusm createProxyPerm proxy_permission=<Name of the proxypermission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Grant Proxy permission to Proxy group eusm grantProxyPerm proxy_permission=<Name of the proxy permission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<password> group_dn="<dn of the enterprise group>" To Map proxy permission to proxy user in DB eusm addTargetUser proxy_permission=<Name of the proxy permission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> database_name=<SID of the target database> target_user=<target database user> dbuser=<Database user with DBA privileges> dbuser_password=<database user password> dbconnect_string=<database_host>:<port>:<DBSID> Enterprise role to Global role mapping eusm addGlobalRole enterprise_role=<rdn of the enterprise role> domain_name=<Domain> realm_dn="<realm>" database_name=<SID of the target database> global_role=<name of the global role defined in the target database> dbuser=<database user> dbuser_password=<database user password> dbconnect_string=<database_host>:<port>:<DBSID> ldap_host=<oid_hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password>

  • GRUB is not Booting Correctly

    - by msknapp
    I have a PC with three hard disks. Windows 7 is installed on the first, Ubuntu 14.04 is installed on the third. After I re-booted, it went straight to Windows 7. So I tried explicitly telling my PC to boot using the third hard disk, but that just takes me to the grub rescue prompt. I followed Scott Severence's instructions here to try and recover. Essentially, I updated grub, reinstalled grub, and then updated it again. After re-booting, absolutely nothing had changed. So instead I tried using the boot-repair tool. In the past it had failed for me, saying that I had programs running and it could not unmount drives, when I was running nothing. I never figured out how to solve that problem, but it went away when I bought another hard drive and used that for my Ubuntu installation, I don't know why. In any case, I ran the boot-repair tool and this time it said it was successful. First time for everything right? I re-booted, only to be taken straight to the grub rescue prompt. So I changed my BIOS settings to use the third hard disk for boot start up. That is the same hard drive where I have Ubuntu and grub installed, and the same one that the grub-repair tool told me to use. It still took me straight to the grub rescue prompt. So I went from not being able to boot Ubuntu, to not being able to boot either OS installed on my system. Thanks boot-repair! Boot repair gave me this URL for future troubleshooting: http://paste.ubuntu.com/8131669 When I try to boot from the third hard disk, this is my console: Loading Operating System ... error: attempt to read or write outside of disk 'hd0'. Entering rescue mode... grub rescue> grub rescue> set cmdpath=(hd0) prefix=(hd0,gpt2)/boot/grub root=hd0,gpt2 grub rescue> ls (hd0) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) (hd1) (hd2) (hd2,gpt2) (hd2,gpt1) (hd3) Those values look correct to me. I have also experimented with changing some of those values, but 'insmod normal' always throws the same error. Somebody please tell me how to fix this. I have tried everything, reinstalling grub, and running boot-repair. =========================== Update: I think the problem might be that the ubuntu installer did not partition my hard disk correctly. I booted from live USB and then launched gparted and looked at how it partitioned things. This is what gparted says: Partition, File System, Size, Used, Unused, Flags /dev/sda1 (!), unknown, 1.00 MiB, ---, ---, bios_grub /dev/sda2, ext4, 2.71 TiB, 47.30 GiB, 2.67 TiB, /dev/sda3, linux-swap, 16.00 GiB, 0.00 B, 16.00 GiB, So that first line looks problematic. It is supposed to be the /boot partition. However, it was given only 1 MiB? I am assuming that MiB is actually supposed to mean megabyte, no idea why that 'i' is there. It also says the file system is unknown. I read the answer by andrew here, and he says he had to do a custom install, explicitly configuring the boot partition. So I think that maybe Ubuntu's installer has a bug in it, where it does not set up the boot partition correctly if you are not installing on the first hard disk in your computer. I am going to try reinstalling with a custom partition scheme. I read elsewhere (askubuntu won't let me post another link) that I don't even need a /boot partition any more. So instead of following Andrew's instructions ver batim, I'm first going to try having just two partitions: one for /, and another for my 16GB swap space. Both as primary partitions. The first will be formatted as ext4. If that doesn't work, I may try again using /boot. ======================== So I did my custom install with no /boot partition, and it did not work. When I rebooted, I had an error message saying that some address did not exist. So for the hundredth time, I booted from the live USB, and ran boot-repair. Now I get this message GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. I feel like I'm running in circles and nobody will help me.

  • Managing text-maps in a 2D array on to be painted on HTML5 Canvas

    - by weka
    So, I'm making a HTML5 RPG just for fun. The map is a <canvas> (512px width, 352px height | 16 tiles across, 11 tiles top to bottom). I want to know if there's a more efficient way to paint the <canvas>. Here's how I have it right now. How tiles are loaded and painted on map The map is being painted by tiles (32x32) using the Image() piece. The image files are loaded through a simple for loop and put into an array called tiles[] to be PAINTED on using drawImage(). First, we load the tiles... and here's how it's being done: // SET UP THE & DRAW THE MAP TILES tiles = []; var loadedImagesCount = 0; for (x = 0; x <= NUM_OF_TILES; x++) { var imageObj = new Image(); // new instance for each image imageObj.src = "js/tiles/t" + x + ".png"; imageObj.onload = function () { console.log("Added tile ... " + loadedImagesCount); loadedImagesCount++; if (loadedImagesCount == NUM_OF_TILES) { // Onces all tiles are loaded ... // We paint the map for (y = 0; y <= 15; y++) { for (x = 0; x <= 10; x++) { theX = x * 32; theY = y * 32; context.drawImage(tiles[5], theY, theX, 32, 32); } } } }; tiles.push(imageObj); } Naturally, when a player starts a game it loads the map they last left off. But for here, it an all-grass map. Right now, the maps use 2D arrays. Here's an example map. [[4, 1, 4, 1, 4, 1, 4, 1, 4, 1, 4, 1, 1, 1, 1, 1], [1, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 1], [13, 13, 13, 13, 1, 1, 1, 1, 13, 13, 13, 13, 13, 13, 13, 1], [13, 13, 13, 13, 1, 13, 13, 1, 13, 13, 13, 13, 13, 13, 13, 1], [13, 13, 13, 13, 1, 13, 13, 1, 13, 13, 13, 13, 13, 13, 13, 1], [13, 13, 13, 13, 1, 13, 13, 1, 13, 13, 13, 13, 13, 13, 13, 1], [13, 13, 13, 13, 1, 1, 1, 1, 13, 13, 13, 13, 13, 13, 13, 1], [13, 13, 13, 13, 13, 13, 13, 1, 13, 13, 13, 13, 13, 13, 13, 1], [13, 13, 13, 13, 13, 11, 11, 11, 13, 13, 13, 13, 13, 13, 13, 1], [13, 13, 13, 1, 1, 1, 1, 1, 1, 1, 13, 13, 13, 13, 13, 1], [1, 1, 1, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 1, 1, 1]]; I get different maps using a simple if structure. Once the 2d array above is return, the corresponding number in each array will be painted according to Image() stored inside tile[]. Then drawImage() will occur and paint according to the x and y and times it by 32 to paint on the correct x-y coordinate. How multiple map switching occurs With my game, maps have five things to keep track of: currentID, leftID, rightID, upID, and bottomID. currentID: The current ID of the map you are on. leftID: What ID of currentID to load when you exit on the left of current map. rightID: What ID of currentID to load when you exit on the right of current map. downID: What ID of currentID to load when you exit on the bottom of current map. upID: What ID of currentID to load when you exit on the top of current map. Something to note: If either leftID, rightID, upID, or bottomID are NOT specific, that means they are a 0. That means they cannot leave that side of the map. It is merely an invisible blockade. So, once a person exits a side of the map, depending on where they exited... for example if they exited on the bottom, bottomID will the number of the map to load and thus be painted on the map. Here's a representational .GIF to help you better visualize: As you can see, sooner or later, with many maps I will be dealing with many IDs. And that can possibly get a little confusing and hectic. The obvious pros is that it load 176 tiles at a time, refresh a small 512x352 canvas, and handles one map at time. The con is that the MAP ids, when dealing with many maps, may get confusing at times. My question Is this an efficient way to store maps (given the usage of tiles), or is there a better way to handle maps? I was thinking along the lines of a giant map. The map-size is big and it's all one 2D array. The viewport, however, is still 512x352 pixels. Here's another .gif I made (for this question) to help visualize: Sorry if you cannot understand my English. Please ask anything you have trouble understanding. Hopefully, I made it clear. Thanks.

  • Navigate Quickly with JustCode and Ctrl+Click

    Ctrl + Click is a widely used shortcut for Go To Definition in many development environments but not in Visual Studio. We, the JustCode team, find it really useful so we added it to Visual Studio. But we didn't stop there - we improved it even further. Read on to find the details. With JustCode you get an enhanced Go To Definition. By default you can execute it in the Visual Studio editor using one of the following shortcuts: Middle Click, Ctrl+Left Click, F12, Ctrl+Enter, Ctrl+B. The first usage of this feature is not much different from the default Visual Studio Go To Definition command use it where a member, type, method, property, etc is used to navigate to the definition of that item. For example, if you have this method:         public void Start()         {             lion = new Lion();             lion.Roar();         } If you hold Ctrl and click on the usage of the lion you will go to the lion member definition. If you hold Ctrl and click on the Lion you will go to the Lion class definition. What we added is the ability to easily find all the usages of the item you just navigated to. For example:     public class Lion     {         public void Roar()         {             Console.WriteLine("Rhaaaar");         }     }   If you hold Ctrl and click on the Lion definition you will see all the usages of the Lion type; if you click on the Roar method definition you will see all the usages of the Roar method: And if there is only one usage you will get automatically to that usage. In the examples I use C#, but it works also in VB.NET, JavaScript, ASP.NET and XAML. Why we like this feature? Let me first start with how the Ctrl+Click (or Go To Definition command) is used. We noticed that developers use it especially in what we call "code browsing sessions". In simple words this is when you browse around the code looking for a bug, just reading the code or searching for something. Sounds familiar? In our experience when you go to the definition of some item you often want to know more about it and the first thing you need is to find its usages. With JustCode this is just one click away. Why Ctrl+Click/Middle Click over F12/Ctrl+Enter/Ctrl+B? Actually you can use all of them. But during these "code browsing sessions" we noticed that most developers use the mouse. So the mouse is already in use and pressing Ctrl+Click (or the Middle Click) is so natural. During heavy coding sessions or if you are a keyboard type developer F12 (or any of the other keyboard shortcuts) is the key. We really use heavily this feature not only in our team but in the whole company. It saves us a bit of time many times a day. And it adds up. We hope you will like it too. Your feedback is more than welcome for us. P.S. If you dont want JustCode to capture the Ctrl+Click and the Middle Click in the editor, you can change that in JustCode->Options->General in the Navigation group. Keyboard shortcuts can be reassigned using the Visual Studio keyboard shortcuts editor.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • OIM 11g - Multi Valued attribute reconciliation of a child form

    - by user604275
    This topic gives a brief description on how we can do reconciliation of a child form attribute which is also multi valued from a flat file . The format of the flat file is (an example): ManagementDomain1|Entitlement1|DIRECTORY SERVER,EMAIL ManagementDomain2|Entitlement2|EMAIL PROVIDER INSTANCE - UMS,EMAIL VERIFICATION In OIM there will be a parent form for fields Management domain and Entitlement.Reconciliation will assign Servers ( which are multi valued) to corresponding Management  Domain and Entitlement .In the flat file , multi valued fields are seperated by comma(,). In the design console, Create a form with 'Server Name' as a field and make it a child form . Open the corresponding Resource Object and add this field for reconcilitaion.While adding , choose 'Multivalued' check box. (please find attached screen shot on how to add it , Child Table.docx) Open process definiton and add child form fields for recociliation. Please click on the 'Create Reconcilitaion Profile' buttton on the resource object tab. The API methods used for child form reconciliation are : 1.           reconEventKey =   reconOpsIntf.createReconciliationEvent(resObjName, reconData,                                                            false); ·                                    ‘False’  here tells that we are creating the recon for a child table . 2.               2.       reconOpsIntf.providingAllMultiAttributeData(reconEventKey, RECON_FIELD_IN_RO, true);                RECON_FIELD_IN_RO is the field that we added in the Resource Object while adding for reconciliation, please refer the screen shot) 3.    reconOpsIntf.addDirectBulkMultiAttributeData(reconEventKey,RECON_FIELD_IN_RO, bulkChildDataMapList);                 bulkChildDataMapList  is coded as below :                 List<Map> bulkChildDataMapList = new ArrayList<Map>();                   for (int i = 0; i < stokens.length; i++) {                            Map<String, String> attributeMap = new HashMap<String, String>();                           String serverName = stokens[i].toUpperCase();                           attributeMap.put("Server Name", stokens[i]);                           bulkChildDataMapList.add(attributeMap);                         } 4                  4.       reconOpsIntf.finishReconciliationEvent(reconEventKey); 5.       reconOpsIntf.processReconciliationEvent(reconEventKey); Now, we have to register the plug-in, import metadata into MDS and then create a scheduled job to execute which will run the reconciliation.

  • Efficient Way to Draw Grids in XNA

    - by sm81095
    So I am working on a game right now, using Monogame as my framework, and it has come time to render my world. My world is made up of a grid (think Terraria but top-down instead of from the side), and it has multiple layers of grids in a single world. Knowing how inefficient it is to call SpriteBatch.Draw() a lot of times, I tried to implement a system where the tile would only be drawn if it wasn't hidden by the layers above it. The problem is, I'm getting worse performance by checking if it's hidden than when I just let everything draw even if it's not visible. So my question is: how to I efficiently check if a tile is hidden to cut down on the draw() calls? Here is my draw code for a single layer, drawing floors, and then the tiles (which act like walls): public void Draw(GameTime gameTime) { int drawAmt = 0; int width = Tile.TILE_DIM; int startX = (int)_parent.XOffset; int startY = (int)_parent.YOffset; //Gets the starting tiles and the dimensions to draw tiles, so only onscreen tiles are drawn, allowing for the drawing of large worlds int tileDrawWidth = ((CIGame.Instance.Graphics.PreferredBackBufferWidth / width) + 4); int tileDrawHeight = ((CIGame.Instance.Graphics.PreferredBackBufferHeight / width) + 4); int tileStartX = (int)MathHelper.Clamp((-startX / width) - 2, 0, this.Width); int tileStartY = (int)MathHelper.Clamp((-startY / width) - 2, 0, this.Height); #region Draw Floors and Tiles CIGame.Instance.GraphicsDevice.SetRenderTarget(_worldTarget); CIGame.Instance.GraphicsDevice.Clear(Color.Black); CIGame.Instance.SpriteBatch.Begin(); //Draw floors for (int x = tileStartX; x < (int)MathHelper.Clamp(tileStartX + tileDrawWidth, 0, this.Width); x++) { for (int y = tileStartY; y < (int)MathHelper.Clamp(tileStartY + tileDrawHeight, 0, this.Height); y++) { //Check if this tile is hidden by layer above it bool visible = true; for (int i = this.LayerNumber; i <= _parent.ActiveLayer; i++) { if (this.LayerNumber != (_parent.Layers - 1) && (_parent.GetTileAt(x, y, i + 1).Opacity >= 1.0f || _parent.GetFloorAt(x, y, i + 1).Opacity >= 1.0f)) { visible = false; break; } } //Only draw if visible under the tile above it if (visible && this.GetTileAt(x, y).Opacity < 1.0f) { Texture2D tex = WorldTextureManager.GetFloorTexture((Floor)_floors[x, y]); Rectangle source = WorldTextureManager.GetSourceForIndex(((Floor)_floors[x, y]).GetTextureIndexFromSurroundings(x, y, this), tex); Rectangle draw = new Rectangle(startX + x * width, startY + y * width, width, width); CIGame.Instance.SpriteBatch.Draw(tex, draw, source, Color.White * ((Floor)_floors[x, y]).Opacity); drawAmt++; } } } //Draw tiles for (int x = tileStartX; x < (int)MathHelper.Clamp(tileStartX + tileDrawWidth, 0, this.Width); x++) { for (int y = tileStartY; y < (int)MathHelper.Clamp(tileStartY + tileDrawHeight, 0, this.Height); y++) { //Check if this tile is hidden by layers above it bool visible = true; for (int i = this.LayerNumber; i <= _parent.ActiveLayer; i++) { if (this.LayerNumber != (_parent.Layers - 1) && (_parent.GetTileAt(x, y, i + 1).Opacity >= 1.0f || _parent.GetFloorAt(x, y, i + 1).Opacity >= 1.0f)) { visible = false; break; } } if (visible) { Texture2D tex = WorldTextureManager.GetTileTexture((Tile)_tiles[x, y]); Rectangle source = WorldTextureManager.GetSourceForIndex(((Tile)_tiles[x, y]).GetTextureIndexFromSurroundings(x, y, this), tex); Rectangle draw = new Rectangle(startX + x * width, startY + y * width, width, width); CIGame.Instance.SpriteBatch.Draw(tex, draw, source, Color.White * ((Tile)_tiles[x, y]).Opacity); drawAmt++; } } } CIGame.Instance.SpriteBatch.End(); Console.WriteLine(drawAmt); CIGame.Instance.GraphicsDevice.SetRenderTarget(null); //TODO: Change to new rendertarget instead of null #endregion } So I was wondering if this is an efficient way, but I'm going about it wrongly, or if there is a different, more efficient way to check if the tiles are hidden. EDIT: For example of how much it affects performance: using a world with three layers, allowing everything to draw no matter what gives me 60FPS, but checking if its visible with all of the layers above it gives me only 20FPS, while checking only the layer immediately above it gives me a fluctuating FPS between 30 and 40FPS.

  • Data Source Security Part 4

    - by Steve Felts
    So far, I have covered Client Identity and Oracle Proxy Session features, with WLS or database credentials.  This article will cover one more feature, Identify-based pooling.  Then, there is one more topic to cover - how these options play with transactions.Identity-based Connection Pooling An identity based pool creates a heterogeneous pool of connections.  This allows applications to use a JDBC connection with a specific DBMS credential by pooling physical connections with different DBMS credentials.  The DBMS credential is based on either the WebLogic user mapped to a database user or the database user directly, based on the “use database credentials” setting as described earlier. Using this feature enabled with “use database credentials” enabled seems to be what is proposed in the JDBC standard, basically a heterogeneous pool with users specified by getConnection(user, password). The allocation of connections is more complex if Enable Identity Based Connection Pooling attribute is enabled on the data source.  When an application requests a database connection, the WebLogic Server instance selects an existing physical connection or creates a new physical connection with requested DBMS identity. The following section provides information on how heterogeneous connections are created:1. At connection pool initialization, the physical JDBC connections based on the configured or default “initial capacity” are created with the configured default DBMS credential of the data source.2. An application tries to get a connection from a data source.3a. If “use database credentials” is not enabled, the user specified in getConnection is mapped to a DBMS credential, as described earlier.  If the credential map doesn’t have a matching user, the default DBMS credential is used from the datasource descriptor.3b. If “use database credentials” is enabled, the user and password specified in getConnection are used directly.4. The connection pool is searched for a connection with a matching DBMS credential.5. If a match is found, the connection is reserved and returned to the application.6. If no match is found, a connection is created or reused based on the maximum capacity of the pool: - If the maximum capacity has not been reached, a new connection is created with the DBMS credential, reserved, and returned to the application.- If the pool has reached maximum capacity, based on the least recently used (LRU) algorithm, a physical connection is selected from the pool and destroyed. A new connection is created with the DBMS credential, reserved, and returned to the application. It should be clear that finding a matching connection is more expensive than a homogeneous pool.  Destroying a connection and getting a new one is very expensive.  If you can use a normal homogeneous pool or one of the light-weight options (client identity or an Oracle proxy connection), those should be used instead of identity based pooling. Regardless of how physical connections are created, each physical connection in the pool has its own DBMS credential information maintained by the pool. Once a physical connection is reserved by the pool, it does not change its DBMS credential even if the current thread changes its WebLogic user credential and continues to use the same connection. To configure this feature, select Enable Identity Based Connection Pooling.  See http://docs.oracle.com/cd/E24329_01/apirefs.1211/e24401/taskhelp/jdbc/jdbc_datasources/EnableIdentityBasedConnectionPooling.html  "Enable identity-based connection pooling for a JDBC data source" in Oracle WebLogic Server Administration Console Help. You must make the following changes to use Logging Last Resource (LLR) transaction optimization with Identity-based Pooling to get around the problem that multiple users will be accessing the associated transaction table.- You must configure a custom schema for LLR using a fully qualified LLR table name. All LLR connections will then use the named schema rather than the default schema when accessing the LLR transaction table.  - Use database specific administration tools to grant permission to access the named LLR table to all users that could access this table via a global transaction. By default, the LLR table is created during boot by the user configured for the connection in the data source. In most cases, the database will only allow access to this user and not allow access to mapped users. Connections within Transactions Now that we have covered the behavior of all of these various options, it’s time to discuss the exception to all of the rules.  When you get a connection within a transaction, it is associated with the transaction context on a particular WLS instance. When getting a connection with a data source configured with non-XA LLR or 1PC (using the JTS driver) with global transactions, the first connection obtained within the transaction is returned on subsequent connection requests regardless of the values of username/password specified and independent of the associated proxy user session, if any. The connection must be shared among all users of the connection when using LLR or 1PC. For XA data sources, the first connection obtained within the global transaction is returned on subsequent connection requests within the application server, regardless of the values of username/password specified and independent of the associated proxy user session, if any.  The connection must be shared among all users of the connection within a global transaction within the application server/JVM.

  • What's New in Oracle VM VirtualBox 4.2?

    - by Fat Bloke
    A year is a long time in the IT industry. Since the last VirtualBox feature release, which was a little over a year ago, we've seen: new releases of cool new operating systems, such as Windows 8, ChromeOS, and Mountain Lion; we've seen a myriad of new Linux releases from big Enterprise class distributions like Oracle 6.3, to accessible desktop distros like Ubuntu 12.04 and Fedora 17; and we've also seen the spec of a typical PC or laptop double in power. All of these events have influenced our new VirtualBox version which we're releasing today. Here's how... Powerful hosts  One of the trends we've seen is that as the average host platform becomes more powerful, our users are consistently running more and more vm's. Some of our users have large libraries of vm's of various vintages, whilst others have groups of vm's that are run together as an assembly of the various tiers in a multi-tiered software solution, for example, a database tier, middleware tier, and front-ends.  So we're pleased to unveil a more powerful VirtualBox Manager to address the needs of these users: VM Groups Groups allow you to organize your VM library in a sensible way, e.g.  by platform type, by project, by version, by whatever. To create groups you can drag one VM onto another or select one or more VM's and choose Machine...Group from the menu bar. You can expand and collapse groups to save screen real estate, and you can Enter and Leave a group (think iPad navigation here) by using the right and left arrow keys when groups are selected. But groups are more than passive folders, because you can now also perform operations on groups, rather than all the individual VMs. So if you have a multi-tiered solution you can start the whole stack up with just one click. Autostart Many VirtualBox users run dedicated services in their VMs, for example, running a Wiki. With these types of VM workloads, you really want the VM start up when the host machine boots up. So with 4.2 we've introduced a cross-platform Auto-start mechanism to allow you to treat VMs as host services. Headless VM Launching With VM's such as web servers, wikis, and other types of server-class workloads, the Console of the VM is pretty much redundant. For some time now VirtualBox has offered a separate launch mechanism for these VM's, namely the command-line interface commands VBoxHeadless or VBoxManage startvm ... --type headless commands. But with 4.2 we also allow you launch headless VMs from the Manager. Simply hold down Shift when launching the VM from the Manager.  It's that easy. But how do you stop a headless VM? Well, with 4.2 we allow you to Close the VM from the Manager. (BTW best to use the ACPI Shutdown method which allows the guest VM to close down gracefully.) Easy VM Creation For our expert users, the  New VM Wizard was a little tiresome, so now there's a faster 2-click VM creation mode. Just Hide the description when creating a new VM. Powerful VMs  As the hosts have become more powerful, so are the guests that are running inside them. Here are some of the 4.2 features to accommodate them: Virtual Network Interface Cards  With 4.2, it's now possible to create VMs with up to 36 NICs, when using the ICH9 chipset emulation. But with great power comes great responsibility (didn't Obi-Wan say something similar?), and so we have also introduced bandwidth limiting to prevent a rogue VM stealing the whole pipe. VLAN tagging Some of our users leverage VLANs extensively so we've enhanced the E1000 NICs to support this.  Processor Performance If you are running a CPU which supports Nested Paging (aka EPT in the Intel world) such as most of the Core i5 and i7 CPUs, or are running an AMD Bulldozer or later, you should see some performance improvements from our work with these processors. And while we're talking Processors, we've added support for some of the more modern VIA CPUs too. Powerful Automation Because VirtualBox runs atop a fully blown operating system, it makes sense to leverage the capabilities of the host to run scripts that can drive the guest VMs. Guest Automation was introduced in a prior release but with 4.2 we've revamped the APIs to allow a richer and more powerful set of operations to be executed by the guest. Check out the IGuest APIs in the VirtualBox Programming Guide and Reference (SDK). Powerful Platforms  All the hardcore engineering that has gone into 4.2 has been done for a purpose and that is to deliver a fast and powerful engine that can run almost any x86 OS because of the integrity of the virtualization. So we're pleased to add support for these platforms: Mac OS X "Mountain Lion"  Windows 8 Windows Server 2012 Ubuntu 12.04 (“Precise Pangolin”) Fedora 17 Oracle Linux 6.3  Here's the proof: We don't have time to go into the myriad of smaller improvements such as support for burning audio CDs from a guest, bi-directional clipboard control,  drag-and-drop of files into Linux guests, etc. so we'll leave that as an exercise for the user as soon as you've downloaded from the Oracle or community site and taken a peek at the User Guide. So all in all, a pretty solid release, one that we hope you'll enjoy discovering. - FB

  • Please help me understand why my XSL Transform is not transforming

    - by Damovisa
    I'm trying to transform one XML format to another using XSL. Try as I might, I can't seem to get a result. I've hacked away at this for a while now and I've had no success. I'm not even getting any exceptions. I'm going to post the entire code and hopefully someone can help me work out what I've done wrong. I'm aware there are likely to be problems in the xsl I have in terms of selects and matches, but I'm not fussed about that at the moment. The output I'm getting is the input XML without any XML tags. The transformation is simply not occurring. Here's my XML Document: <?xml version="1.0"?> <Transactions> <Account> <PersonalAccount> <AccountNumber>066645621</AccountNumber> <AccountName>A Smith</AccountName> <CurrentBalance>-200125.96</CurrentBalance> <AvailableBalance>0</AvailableBalance> <AccountType>LOAN</AccountType> </PersonalAccount> </Account> <StartDate>2010-03-01T00:00:00</StartDate> <EndDate>2010-03-23T00:00:00</EndDate> <Items> <Transaction> <ErrorNumber>-1</ErrorNumber> <Amount>12000</Amount> <Reference>Transaction 1</Reference> <CreatedDate>0001-01-01T00:00:00</CreatedDate> <EffectiveDate>2010-03-15T00:00:00</EffectiveDate> <IsCredit>true</IsCredit> <Balance>-324000</Balance> </Transaction> <Transaction> <ErrorNumber>-1</ErrorNumber> <Amount>11000</Amount> <Reference>Transaction 2</Reference> <CreatedDate>0001-01-01T00:00:00</CreatedDate> <EffectiveDate>2010-03-14T00:00:00</EffectiveDate> <IsCredit>true</IsCredit> <Balance>-324000</Balance> </Transaction> </Items> </Transactions> Here's my XSLT: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="xml" /> <xsl:param name="currentdate"></xsl:param> <xsl:template match="Transactions"> <xsl:element name="OFX"> <xsl:element name="SIGNONMSGSRSV1"> <xsl:element name="SONRS"> <xsl:element name="STATUS"> <xsl:element name="CODE">0</xsl:element> <xsl:element name="SEVERITY">INFO</xsl:element> </xsl:element> <xsl:element name="DTSERVER"><xsl:value-of select="$currentdate" /></xsl:element> <xsl:element name="LANGUAGE">ENG</xsl:element> </xsl:element> </xsl:element> <xsl:element name="BANKMSGSRSV1"> <xsl:element name="STMTTRNRS"> <xsl:element name="TRNUID">1</xsl:element> <xsl:element name="STATUS"> <xsl:element name="CODE">0</xsl:element> <xsl:element name="SEVERITY">INFO</xsl:element> </xsl:element> <xsl:element name="STMTRS"> <xsl:element name="CURDEF">AUD</xsl:element> <xsl:element name="BANKACCTFROM"> <xsl:element name="BANKID">RAMS</xsl:element> <xsl:element name="ACCTID"><xsl:value-of select="Account/PersonalAccount/AccountNumber" /></xsl:element> <xsl:element name="ACCTTYPE"><xsl:value-of select="Account/PersonalAccount/AccountType" /></xsl:element> </xsl:element> <xsl:element name="BANKTRANLIST"> <xsl:element name="DTSTART"><xsl:value-of select="StartDate" /></xsl:element> <xsl:element name="DTEND"><xsl:value-of select="EndDate" /></xsl:element> <xsl:for-each select="Items/Transaction"> <xsl:element name="STMTTRN"> <xsl:element name="TRNTYPE"><xsl:choose><xsl:when test="IsCredit">CREDIT</xsl:when><xsl:otherwise>DEBIT</xsl:otherwise></xsl:choose></xsl:element> <xsl:element name="DTPOSTED"><xsl:value-of select="EffectiveDate" /></xsl:element> <xsl:element name="DTUSER"><xsl:value-of select="CreatedDate" /></xsl:element> <xsl:element name="TRNAMT"><xsl:value-of select="Amount" /></xsl:element> <xsl:element name="FITID" /> <xsl:element name="NAME"><xsl:value-of select="Reference" /></xsl:element> <xsl:element name="MEMO"><xsl:value-of select="Reference" /></xsl:element> </xsl:element> </xsl:for-each> </xsl:element> <xsl:element name="LEDGERBAL"> <xsl:element name="BALAMT"><xsl:value-of select="Account/PersonalAccount/CurrentBalance" /></xsl:element> <xsl:element name="DTASOF"><xsl:value-of select="EndDate" /></xsl:element> </xsl:element> </xsl:element> </xsl:element> </xsl:element> </xsl:element> </xsl:template> </xsl:stylesheet> Here's my method to transform my XML: public string TransformToXml(XmlElement xmlElement, Dictionary<string, object> parameters) { string strReturn = ""; // Load the XSLT Document XslCompiledTransform xslt = new XslCompiledTransform(); xslt.Load(xsltFileName); // arguments XsltArgumentList args = new XsltArgumentList(); if (parameters != null && parameters.Count > 0) { foreach (string key in parameters.Keys) { args.AddParam(key, "", parameters[key]); } } //Create a memory stream to write to Stream objStream = new MemoryStream(); // Apply the transform xslt.Transform(xmlElement, args, objStream); objStream.Seek(0, SeekOrigin.Begin); // Read the contents of the stream StreamReader objSR = new StreamReader(objStream); strReturn = objSR.ReadToEnd(); return strReturn; } The contents of strReturn is an XML tag (<?xml version="1.0" encoding="utf-8"?>) followed by a raw dump of the contents of the original XML document, stripped of XML tags.

  • WebLogic job scheduling

    - by XpiritO
    Hello, overflowers :) I'm trying to implement a WebLogic job scheduling example, to test my cluster capabilities of fail-over on scheduled tasks (to ensure that these tasks are executed on fail over scenario). With this in mind, I've been following this example and trying to configure everything accordingly. Here are the steps I've done so far: Configured a cluster with 1 admin server (AdminServer) and 2 managed instances (Noddy and Snoopy); Set up database tables (using Oracle XE): ACTIVE and WEBLOGIC_TIMERS; Set up data source to access DB and associated it to the scheduling tasks under "Settings for cluster" "Scheduling"; Implemented a job (TimerListener) and a servlet to initialize the job scheduling, as follows: . package timedexecution; import java.io.IOException; import java.io.PrintWriter; import java.io.Serializable; import java.text.SimpleDateFormat; import java.util.Date; import javax.naming.InitialContext; import javax.naming.NamingException; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import commonj.timers.Timer; import commonj.timers.TimerListener; import commonj.timers.TimerManager; public class TimerServlet extends HttpServlet { private static final long serialVersionUID = 1L; protected static void logMessage(String message, PrintWriter out){ out.write("<p>"+ message +"</p>"); System.out.println(message); } @Override public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PrintWriter out = response.getWriter(); // out.println("<html>"); out.println("<head><title>TimerServlet</title></head>"); // try { // logMessage("service() entering try block to intialize the timer from JNDI", out); // InitialContext ic = new InitialContext(); TimerManager jobScheduler = (TimerManager)ic.lookup("weblogic.JobScheduler"); // logMessage("jobScheduler reference " + jobScheduler, out); // jobScheduler.schedule(new ExampleTimerListener(), 0, 30*1000); // logMessage("Timer scheduled!", out); // //execute this job every 30 seconds logMessage("service() started the timer", out); // logMessage("Started the timer - status:", out); // } catch (NamingException ne) { String msg = ne.getMessage(); logMessage("Timer schedule failed!", out); logMessage(msg, out); } catch (Throwable t) { logMessage("service() error initializing timer manager with JNDI name weblogic.JobScheduler " + t,out); } // out.println("</body></html>"); out.close(); } private static class ExampleTimerListener implements Serializable, TimerListener { private static final long serialVersionUID = 8313912206357147939L; public void timerExpired(Timer timer) { SimpleDateFormat sdf = new SimpleDateFormat(); System.out.println( "timerExpired() called at " + sdf.format( new Date() ) ); } } } Then I executed the servlet to start the scheduling on the first managed instance (Noddy server), which returned as expected: (Servlet execution output) service() entering try block to intialize the timer from JNDI jobScheduler reference weblogic.scheduler.TimerServiceImpl@43b4c7 Timer scheduled! service() started the timer Started the timer - status: Which resulted in the creation of 2 rows in my DB tables: WEBLOGIC_TIMERS table state after servlet execution: "EDIT"; "TIMER_ID"; "LISTENER"; "START_TIME"; "INTERVAL"; "TIMER_MANAGER_NAME"; "DOMAIN_NAME"; "CLUSTER_NAME"; ""; "Noddy_1268653040156"; "[datatype]"; "1268653040156"; "30000"; "weblogic.JobScheduler"; "myCluster"; "Cluster" ACTIVE table state after servlet execution: "EDIT"; "SERVER"; "INSTANCE"; "DOMAINNAME"; "CLUSTERNAME"; "TIMEOUT"; ""; "service.SINGLETON_MASTER"; "6382071947583985002/Noddy"; "QRENcluster"; "Cluster"; "10.03.15" Although, the job is not executed as scheduled. It should print a message on the server's log output (Noddy.out file) with a timestamp, saying that the timer had expired. It doesn't. My log files state as follows: Admin server log (myCluster.log file): ####<15/Mar/2010 10H45m GMT> <Warning> <Cluster> <test-ad> <Noddy> <[STANDBY] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1268649925727> <BEA-000192> <No currently living server was found that could host TimerMaster.

  • Snort's problems in generating alert from Darpa 1998 intrusion detection dataset.

    Hi. I’m working on DARPA 1998 intrusion detection dataset. When I run snort on this dataset (outside.tcpdump file), snort don’t generate complete list of alerts.

Another problem in generatin alert is in time stamp of generated alerts. This means when I run snort on a specific day of dataset, snort insert incorrect time stamp for that alert.

  • Beginning Java (Working with Arrays; Class Assignment)

    - by Jason
    I am to the point where I feel as if I correctly wrote the code for this homework assignment. We were given a skeleton and 2 classes that we had to import (FileIOHelper and Student). /* * Created: *** put the date here *** * * Author: *** put your name here *** * * The program will read information about students and their * scores from a file, and output the name of each student with * all his/her scores and the total score, plus the average score * of the class, and the name and total score of the students with * the highest and lowest total score. */ // import java.util.Scanner; import java.io.*; // C:\Users\Adam\info.txt public class Lab6 { public static void main(String[] args) throws IOException { // Fill in the body according to the following comments Scanner key boardFile = new Scanner(System.in); // Input file name String filename = getFileName(keyboardFile); //Open the file // Input number of students int numStudents = FileIOHelper.getNumberOfStudents(filename); Student students[] = new Student[numStudents]; // Input all student records and create Student array and // integer array for total scores int totalScore[] = new int[students.length]; for (int i = 0; i < students.length; i++){ for(int j = 1; j < 4;

  • Would anyone tell me how to fetch the media:thumb element's attribute from a json feed?

    - by ash
    I made a yahoo pipe that pulls up the atoms as json format; however, I can fetch and display all the elements in my html page except for the element's attribute. Would anyone tell me how to fetch the media:thumb element's attribute from a json feed? I am pasting the html page's code with javascript. If you save the html page and then view it in browser, you will see that all the necessary elements get output at html page except for the media:thumb as I cannot display the attribute of media:thumb when the feed is formatted as json. I am also pasting the some portion of the json feed so that you can have an idea what i am talking about. Please tell me how to retrieve attribute from media:thumb element of a json feed by using plain javascript but no server side code or javascript library. Thank you. function getFeed(feed){ var newScript = document.createElement('script'); newScript.type = 'text/javascript'; newScript.src = 'http://pipes.yahoo.com/pipes/pipe.run?_id=40616620df99780bceb3fe923cecd216&_render=json&_callback=piper'; document.getElementsByTagName("head")[0].appendChild(newScript); } function piper(feed){ var tmp=''; for (var i=0; i'; tmp+=feed.value.items[i].title+''; tmp+=feed.value.items[i].author.name+''; tmp+=feed.value.items[i].published+''; if (feed.value.items[i].description) { tmp+=feed.value.items[i].description+''; } tmp+='<hr>'; } document.getElementById('rssLayer').innerHTML=tmp; } </script> bchnbc ..............................................................

  • Reusing XSL template to be invoked with different relative XPaths

    - by meomaxy
    Here is my contrived example that illustrates what I am attempting to accomplish. I have an input XML file that I wish to flatten for further processing. Input file: <BICYCLES> <BICYCLE> <COLOR>BLUE</COLOR> <WHEELS> <WHEEL> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTORS> <REFLECTOR> <REFLECTOR_NUM>1</REFLECTOR_NUM> <COLOR>RED</COLOR> <SHAPE>SQUARE</SHAPE> </REFLECTOR> <REFLECTOR> <REFLECTOR_NUM>2</REFLECTOR_NUM> <COLOR>WHITE</COLOR> <SHAPE>ROUND</SHAPE> </REFLECTOR> </REFLECTORS> </WHEEL> <WHEEL> <WHEEL_TYPE>REAR</WHEEL_TYPE> <FLAT>NO</FLAT> </WHEEL> </WHEELS> </BICYCLE> </BICYCLES> The input is a list of <BICYCLE> nodes. Each <BICYCLE> has a <COLOR> and optionally has <WHEELS>. <WHEELS> is a list of <WHEEL> nodes, each of which has a few attributes, and optionally has <REFLECTORS>. <REFLECTORS> is a list of <REFLECTOR> nodes, each of which has a few attributes. The goal is to flatten this XML. This is the XSL I'm using: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:output method="xml" encoding="UTF-8" indent="yes" omit-xml-declaration="yes" xml:space="preserve"/> <xsl:template match="/"> <BICYCLES> <xsl:apply-templates/> </BICYCLES> </xsl:template> <xsl:template match="BICYCLE"> <xsl:choose> <xsl:when test="WHEELS"> <xsl:apply-templates select="WHEELS"/> </xsl:when> <xsl:otherwise> <BICYCLE> <COLOR><xsl:value-of select="COLOR"/></COLOR> <WHEEL_TYPE/> <FLAT/> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="WHEELS"> <xsl:apply-templates select="WHEEL"/> </xsl:template> <xsl:template match="WHEEL"> <xsl:choose> <xsl:when test="REFLECTORS"> <xsl:apply-templates select="REFLECTORS"/> </xsl:when> <xsl:otherwise> <BICYCLE> <COLOR><xsl:value-of select="../../COLOR"/></COLOR> <WHEEL_TYPE><xsl:value-of select="WHEEL_TYPE"/></WHEEL_TYPE> <FLAT><xsl:value-of select="FLAT"/></FLAT> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="REFLECTORS"> <xsl:apply-templates select="REFLECTOR"/> </xsl:template> <xsl:template match="REFLECTOR"> <BICYCLE> <COLOR><xsl:value-of select="../../../../COLOR"/></COLOR> <WHEEL_TYPE><xsl:value-of select="../../WHEEL_TYPE"/></WHEEL_TYPE> <FLAT><xsl:value-of select="../../FLAT"/></FLAT> <REFLECTOR_NUM><xsl:value-of select="REFLECTOR_NUM"/></REFLECTOR_NUM> <COLOR><xsl:value-of select="COLOR"/></COLOR> <SHAPE><xsl:value-of select="SHAPE"/></SHAPE> </BICYCLE> </xsl:template> </xsl:stylesheet> The output is: <BICYCLES xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM>1</REFLECTOR_NUM> <COLOR>RED</COLOR> <SHAPE>SQUARE</SHAPE> </BICYCLE> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM>2</REFLECTOR_NUM> <COLOR>WHITE</COLOR> <SHAPE>ROUND</SHAPE> </BICYCLE> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>REAR</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </BICYCLES> What I don't like about this is that I'm outputting the color attribute in several forms: <COLOR><xsl:value-of select="../../../../COLOR"/></COLOR> <COLOR><xsl:value-of select="../../COLOR"/></COLOR> <COLOR><xsl:value-of select="COLOR"/></COLOR> <COLOR/> It seems like there ought to be a way to make a named template and invoke it from the various places where it is needed and pass some parameter that represents the path back to the <BICYCLE> node to which it refers. Is there a way to clean this up, say with a named template for bicycle fields, for wheel fields and for reflector fields? In the real world example this is based on, there are many more attributes to a "bicycle" than just color, and I want to make this XSL easy to change to include or exclude fields without having to change the XSL in multiple places.

    I submitted my code for a question on USACO titled "The Clocks". This is the link to the question: http://ace.delos.com/usacoprob2?a=wj7UqN4l7zk&S=clocks This is the output: Compiling...

  • Help with Boost Grammar

    - by Decmanc04
    I have been using the following win32 console code to try to parse a B Machine Grammar embedded within C++ using Boost Spirit grammar template. I am a relatively new Boost user. The code compiles, but when I run the .exe file produced by VC++2008, the program partially parses the input file. I believe the problem is with my grammar definition or the functions attached as semantic atctions.

  • Implementing union of Set using basic java array

    - by lupindeterd
    Note: This is an assignment. Hi, Continuing with my Set implementation using Java basic array, I'm now struggling with the 3 to last function namely the union. import java.io.*; class Set { private int numberOfElements = 0; private String[] setElements = new String[5]; private int maxNumberOfElements = 5; // constructor for our Set class public Set(int numberOfE, int setE, int maxNumberOfE) { int numberOfElements = numberOfE; String[] setElements = new String[setE]; int maxNumberOfElements = maxNumberOfE; } // Helper method to shorten/remove element of array since we're using basic array instead of ArrayList or HashSet from collection interface :( static String[] removeAt(int k, String[] arr) { final int L = arr.length; String[] ret = new String[L - 1]; System.arraycopy(arr, 0, ret, 0, k); System.arraycopy(arr, k + 1, ret, k, L - k - 1); return ret; } int findElement(String element) { int retval = 0; for ( int i = 0; i < setElements.length; i++) { if ( setElements[i] != null && setElements[i].equals(element) ) { return retval = i; } retval = -1; } return retval; } void add(String newValue) { int elem = findElement(newValue); if( numberOfElements < maxNumberOfElements && elem == -1 ) { setElements[numberOfElements] = newValue; numberOfElements++; } } int getLength() { if ( setElements != null ) { return setElements.length; } else { return 0; } } String[] emptySet() { setElements = new String[0]; return setElements; } Boolean isFull() { Boolean True = new Boolean(true); Boolean False = new Boolean(false); if ( setElements.length == maxNumberOfElements ){ return True; } else { return False; } } Boolean isEmpty() { Boolean True = new Boolean(true); Boolean False = new Boolean(false); if ( setElements.length == 0 ) { return True; } else { return False; } } void remove(String newValue) { for ( int i = 0; i < setElements.length; i++) { if ( setElements[i].equals(newValue) ) { setElements = removeAt(i,setElements); } } } int isAMember(String element) { int retval = -1; for ( int i = 0; i < setElements.length; i++ ) { if (setElements[i] != null && setElements[i].equals(element)) { return retval = i; } } return retval; } void printSet() { for ( int i = 0; i < setElements.length; i++) { System.out.println("Member elements on index: "+ i +" " + setElements[i]); } } String[] getMember() { String[] tempArray = new String[setElements.length]; for ( int i = 0; i < setElements.length; i++) { if(setElements[i] != null) { tempArray[i] = setElements[i]; } } return tempArray; } Set union(Set x, Set y) { String[] newtemparray = new String[x.getLength]; newtemparray = x.getMember; return x; } } // This is the SetDemo class that will make use of our Set class class SetDemo { public static void main(String[] args) { //get input from keyboard BufferedReader keyboard; InputStreamReader reader; String temp = ""; reader = new InputStreamReader(System.in); keyboard = new BufferedReader(reader); try { System.out.println("Enter string element to be added" ); temp = keyboard.readLine( ); System.out.println("You entered " + temp ); } catch (IOException IOerr) { System.out.println("There was an error during input"); } /* ************************************************************************** * Test cases for our new created Set class. * ************************************************************************** */ Set setA = new Set(1,10,10); setA.add(temp); setA.add("b"); setA.add("b"); setA.add("hello"); setA.add("world"); setA.add("six"); setA.add("seven"); setA.add("b"); int size = setA.getLength(); System.out.println("Set size is: " + size ); Boolean isempty = setA.isEmpty(); System.out.println("Set is empty? " + isempty ); int ismember = setA.isAMember("sixb"); System.out.println("Element six is member of setA? " + ismember ); Boolean output = setA.isFull(); System.out.println("Set is full? " + output ); setA.printSet(); int index = setA.findElement("world"); System.out.println("Element b located on index: " + index ); setA.remove("b"); setA.emptySet(); int resize = setA.getLength(); System.out.println("Set size is: " + resize ); setA.printSet(); Set setB = new Set(0,10,10); Set SetA = setA.union(setB,setA); } } Ok the method in question will be the implementation of union. As such this: Set union(Set x, Set y) { String[] newtemparray = new String[x.getLength]; newtemparray = x.getMember; return x; } I got this error: symbol : variable getLength location: class Set String[] newtemparray = new String[x.getLength]; ^ d:\javaprojects\Set.java:122: cannot find symbol symbol : variable getMember location: class Set newtemparray = x.getMember; ^ 2 errors My approach for union would be: *) create temporary array of string with size of the object x length. *) store object x members to temporary array by looping the object and calling the getMember *) loop object y members and check if element exist against temporary array. *) discard if it exist/add if it is not there *) return obj x with the union array. thanks, lupin

  • Bulk inserting best way to about it? + Helping me understand fully what I found so far

    - by chobo2
    Hi So I saw this post here and read it and it seems like bulk copy might be the way to go. http://stackoverflow.com/questions/682015/whats-the-best-way-to-bulk-database-inserts-from-c I still have some questions and want to know how things actually work. So I found 2 tutorials. http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx First way uses 2 ado.net 2.0 features. BulkInsert and BulkCopy. the second one uses linq to sql and OpenXML. This sort of appeals to me as I am using linq to sql already and prefer it over ado.net. However as one person pointed out in the posts what he just going around the issue at the cost of performance( nothing wrong with that in my opinion) First I will talk about the 2 ways in the first tutorial I am using VS2010 Express, .net 4.0, MVC 2.0, SQl Server 2005 Is ado.net 2.0 the most current version? Based on the technology I am using, is there some updates to what I am going to show that would improve it somehow? Is there any thing that these tutorial left out that I should know about? BulkInsert I am using this table for all the examples. CREATE TABLE [dbo].[TBL_TEST_TEST] ( ID INT IDENTITY(1,1) PRIMARY KEY, [NAME] [varchar](50) ) SP Code USE [Test] GO /****** Object: StoredProcedure [dbo].[sp_BatchInsert] Script Date: 05/19/2010 15:12:47 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[sp_BatchInsert] (@Name VARCHAR(50) ) AS BEGIN INSERT INTO TBL_TEST_TEST VALUES (@Name); END C# Code /// <summary> /// Another ado.net 2.0 way that uses a stored procedure to do a bulk insert. /// Seems slower then "BatchBulkCopy" way and it crashes when you try to insert 500,000 records in one go. /// http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 /// </summary> private static void BatchInsert() { // Get the DataTable with Rows State as RowState.Added DataTable dtInsertRows = GetDataTable(); SqlConnection connection = new SqlConnection(connectionString); SqlCommand command = new SqlCommand("sp_BatchInsert", connection); command.CommandType = CommandType.StoredProcedure; command.UpdatedRowSource = UpdateRowSource.None; // Set the Parameter with appropriate Source Column Name command.Parameters.Add("@Name", SqlDbType.VarChar, 50, dtInsertRows.Columns[0].ColumnName); SqlDataAdapter adpt = new SqlDataAdapter(); adpt.InsertCommand = command; // Specify the number of records to be Inserted/Updated in one go. Default is 1. adpt.UpdateBatchSize = 1000; connection.Open(); int recordsInserted = adpt.Update(dtInsertRows); connection.Close(); } So first thing is the batch size. Why would you set a batch size to anything but the number of records you are sending? Like I am sending 500,000 records so I did a Batch size of 500,000. Next why does it crash when I do this? If I set it to 1000 for batch size it works just fine. System.Data.SqlClient.SqlException was unhandled Message="A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)" Source=".Net SqlClient Data Provider" ErrorCode=-2146232060 Class=20 LineNumber=0 Number=233 Server="" State=0 StackTrace: at System.Data.Common.DbDataAdapter.UpdatedRowStatusErrors(RowUpdatedEventArgs rowUpdatedEvent, BatchCommandInfo[] batchCommands, Int32 commandCount) at System.Data.Common.DbDataAdapter.UpdatedRowStatus(RowUpdatedEventArgs rowUpdatedEvent, BatchCommandInfo[] batchCommands, Int32 commandCount) at System.Data.Common.DbDataAdapter.Update(DataRow[] dataRows, DataTableMapping tableMapping) at System.Data.Common.DbDataAdapter.UpdateFromDataTable(DataTable dataTable, DataTableMapping tableMapping) at System.Data.Common.DbDataAdapter.Update(DataTable dataTable) at TestIQueryable.Program.BatchInsert() in C:\Users\a\Downloads\TestIQueryable\TestIQueryable\TestIQueryable\Program.cs:line 124 at TestIQueryable.Program.Main(String[] args) in C:\Users\a\Downloads\TestIQueryable\TestIQueryable\TestIQueryable\Program.cs:line 16 InnerException: Time it took to insert 500,000 records with insert batch size of 1000 took "2 mins and 54 seconds" Of course this is no official time I sat there with a stop watch( I am sure there are better ways but was too lazy to look what they where) So I find that kinda slow compared to all my other ones(expect the linq to sql insert one) and I am not really sure why. Next I looked at bulkcopy /// <summary> /// An ado.net 2.0 way to mass insert records. This seems to be the fastest. /// http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 /// </summary> private static void BatchBulkCopy() { // Get the DataTable DataTable dtInsertRows = GetDataTable(); using (SqlBulkCopy sbc = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.KeepIdentity)) { sbc.DestinationTableName = "TBL_TEST_TEST"; // Number of records to be processed in one go sbc.BatchSize = 500000; // Map the Source Column from DataTabel to the Destination Columns in SQL Server 2005 Person Table // sbc.ColumnMappings.Add("ID", "ID"); sbc.ColumnMappings.Add("NAME", "NAME"); // Number of records after which client has to be notified about its status sbc.NotifyAfter = dtInsertRows.Rows.Count; // Event that gets fired when NotifyAfter number of records are processed. sbc.SqlRowsCopied += new SqlRowsCopiedEventHandler(sbc_SqlRowsCopied); // Finally write to server sbc.WriteToServer(dtInsertRows); sbc.Close(); } } This one seemed to go really fast and did not even need a SP( can you use SP with bulk copy? If you can would it be better?) BatchCopy had no problem with a 500,000 batch size.So again why make it smaller then the number of records you want to send? I found that with BatchCopy and 500,000 batch size it took only 5 seconds to complete. I then tried with a batch size of 1,000 and it only took 8 seconds. So much faster then the bulkinsert one above. Now I tried the other tutorial. USE [Test] GO /****** Object: StoredProcedure [dbo].[spTEST_InsertXMLTEST_TEST] Script Date: 05/19/2010 15:39:03 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc C# code. /// <summary> /// This is using linq to sql to make the table objects. /// It is then serailzed to to an xml document and sent to a stored proedure /// that then does a bulk insert(I think with OpenXML) /// http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx /// </summary> private static void LinqInsertXMLBatch() { using (TestDataContext db = new TestDataContext()) { TBL_TEST_TEST[] testRecords = new TBL_TEST_TEST[500000]; for (int count = 0; count < 500000; count++) { TBL_TEST_TEST testRecord = new TBL_TEST_TEST(); testRecord.NAME = "Name : " + count; testRecords[count] = testRecord; } StringBuilder sBuilder = new StringBuilder(); System.IO.StringWriter sWriter = new System.IO.StringWriter(sBuilder); XmlSerializer serializer = new XmlSerializer(typeof(TBL_TEST_TEST[])); serializer.Serialize(sWriter, testRecords); db.insertTestData(sBuilder.ToString()); } } So I like this because I get to use objects even though it is kinda redundant. I don't get how the SP works. Like I don't get the whole thing. I don't know if OPENXML has some batch insert under the hood but I do not even know how to take this example SP and change it to fit my tables since like I said I don't know what is going on. I also don't know what would happen if the object you have more tables in it. Like say I have a ProductName table what has a relationship to a Product table or something like that. In linq to sql you could get the product name object and make changes to the Product table in that same object. So I am not sure how to take that into account. I am not sure if I would have to do separate inserts or what. The time was pretty good for 500,000 records it took 52 seconds The last way of course was just using linq to do it all and it was pretty bad. /// <summary> /// This is using linq to sql to to insert lots of records. /// This way is slow as it uses no mass insert. /// Only tried to insert 50,000 records as I did not want to sit around till it did 500,000 records. /// http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx /// </summary> private static void LinqInsertAll() { using (TestDataContext db = new TestDataContext()) { db.CommandTimeout = 600; for (int count = 0; count < 50000; count++) { TBL_TEST_TEST testRecord = new TBL_TEST_TEST(); testRecord.NAME = "Name : " + count; db.TBL_TEST_TESTs.InsertOnSubmit(testRecord); } db.SubmitChanges(); } } I did only 50,000 records and that took over a minute to do. So I really narrowed it done to the linq to sql bulk insert way or bulk copy. I am just not sure how to do it when you have relationship for either way. I am not sure how they both stand up when doing updates instead of inserts as I have not gotten around to try it yet. I don't think I will ever need to insert/update more than 50,000 records at one type but at the same time I know I will have to do validation on records before inserting so that will slow it down and that sort of makes linq to sql nicer as your got objects especially if your first parsing data from a xml file before you insert into the database.

  • Choosing a VS project type (C++)

    - by typoknig
    Hi all, I do not use C++ much (I try to stick to the easier stuff like Java and VB.NET), but the lately I have not had a choice. When I am picking a project type in VS for some C++ source I download, what project type should I pick? I had just been sticking with Win32 Console Applications, but I just downloaded some code (below) that will not work right even when it compiles with out errors. I have tried to use a CLR Console Application and an empty project too, and have changed many variables along the way, but I cannot get this code to work. I noticed that this code does not have "int main()" at its beginning, does that have something to do with it? Anyways, here is the code, got it from here: /* Demo of modified Lucas-Kanade optical flow algorithm.

  • XMLReader mysteriously fails when parsing document

    - by Valrus
    I have a php script that takes in some XML data and parses it, displaying various bits of information I pull out of it. This has been working fine for over 6 months, until recently it now fails mysteriously on a certain tag. The XML is generated from an outside source(a conferencing bridge), so I have no control over how it is built. I have put the xml through an online validator and it returned no errors. The code also works fine when I connect to another conferencing bridge and get the same output. I have been using XMLReader class so far and tried switching to SmipleXML, but it fails when I create the SimpleXML object using the data. Here is the snippet of where it fails while parsing: <CDR_SUMMARY> <FILE_VERSION>1001</FILE_VERSION> <NAME>Conference Title Hidden</NAME> <ID>10227</ID> <STATUS_STR>Auto_termination,_everybody_quit</STATUS_STR> <STATUS>4</STATUS> <GMT_OFFSET>-4</GMT_OFFSET> <START_TIME>2010-04-14T15:00:33</START_TIME> <DURATION> <HOUR>0</HOUR> <MINUTE>39</MINUTE> <SECOND>37</SECOND> </DURATION> <RESERVE_START_TIME>2010-04-14T15:00:33</RESERVE_START_TIME> <RESERVE_DURATION> <HOUR>12</HOUR> <MINUTE>0</MINUTE> <SECOND>0</SECOND> </RESERVE_DURATION> <MCU_FILE_NAME>c11</MCU_FILE_NAME> <FILE_SAVED>0</FILE_SAVED> <GMT_OFFSET_MINUTE>0</GMT_OFFSET_MINUTE> </CDR_SUMMARY> The <SOUND> opening tag is the last one read before failing. And this is my code: `public function processResponse($xml) { print "Processing List..."; $reader = new XMLReader($xml); try { $reader->setSchema("./schemas/response_trans_cdr_list.xsd"); } catch(Exception $e) { print "Exception:".$e->getMessage(); } //verify xml if($reader->xml($xml)) { while($reader->read()) { //$currentstring = $reader->readstring(); if($reader->name === "ACTION") { //into meat of resposnse while($reader->read()) { //print "Looping..."; //$currentstring = $reader->readInnerXML(); //print $currentstring; if($reader->nodeType == XMLReader::ELEMENT) { if($reader->name === "ID") { $this->conferenceIDs[$this->counter] = $reader->readString(); print "<BR>Conf ID found: ".$this->counter."

It's like it just spontaneously exits the loop.
