  • How do I enable greedy MigrationHeuristic in Karmic?

    - by Matthew
    My laptop performs very poorly for 2d graphics. For example, Docky's zoom effect and compiz effects are very choppy. In Jaunty, I was able to fix this by adding the following line under the "Device" section in my xorg.conf: Option "MigrationHeuristic" "greedy" In Karmic, there is no xorg.conf by default, so I copied my old one (from Jaunty). However, everything is still slow. Here is my xorg.conf: Section "Device" Identifier "Configured Video Device" Option "MigrationHeuristic" "greedy" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection From googling about, it sounds like "MigrationHeuristic" is only an option for the "EXA" mode, while Karmic has switched the intel driver to "UXA". So I tried adding this line under the "Device" section: Option "AccelMethod" "exa" But this didn't help.

  • Management Reporter Installation – Lessons Learned Part II - Dynamics GP

    - by Ryan McBee
    After feeling pretty good about my deployment skills of Management Reporter for Dynamics GP a few weeks ago, I ran into two additional lessons learned that I wanted to share. First, on another new deployment, I got the error shown below which says “An error occurred while creating the database.  View the installation log for additional information.”  This problem initially pointed me to KB 2406948 which did not provide resolution. After several hours of troubleshooting, I found there is an issue if the defaults database locations in SQL Server are set to the root of a drive. You will want to set the default to something like the following to get it installed; C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA.  My default database locations for the data and log files were indeed sitting on the H:\ and I:\ drives. To change this property in your SQL Server Instance you need to open SQL Server Management Studio, right click on the server, and choose properties and then database settings. When I initially got the error, I briefly considered creating the ManagementReporter database by hand, but experience tells me that would have created more headaches down the road. The second problem I ran into with this particular deployment of Management Reporter happened when I started the FRx conversion utility.  The errors reads “The ‘Microsoft.ACE.OLEDB.12.0’ provider is not registered on the local machine. I had a suspicion that this error was related to the fact FRx uses outdated technology and I happened to be on a new install of Server 2008 R2.  A knowledge base search quickly pointed me to KB 2102486. The resolution for this Management Reporter issue was to install the Microsoft Access Database Engine Redistributable, by following the site below. http://www.microsoft.com/downloads/details.aspx?familyid=C06B8369-60DD-4B64-A44B-84B371EDE16D&displaylang=en

  • Running evrouter at boot with init.d, or after xserver starts

    - by J V
    I'm using evrouter to set up mouse button binds, and init.d to start it. My init.d file: #!/bin/bash #Simple init.d script to run evrouter ### BEGIN INIT INFO # Provides: evrouter # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Set evrouter bindings # Description: Set evrouter bindings at boot time. ### END INIT INFO config="/opt/hacks/evrouterrc" case "$1" in start|restart|reload|force-reload) evrouter -c "$config" /dev/input/event* ;; stop) echo "Evrouter is not a daemon, change settings file at '$config' and restart" ;; *) echo "Usage: $0 start" >&2 exit 3 ;; esac evrouter however complains that: evrouter: could not open display "". If evrouter requires xserver to be up, how do I get init to wait until after xserver starts to run this script? If xserver restarts will this script run automatically? Running this with sudo services evrouter start still results in this error, can init.d scripts not tell where my display is? (Not exactly familiar with init, runlevels, etc)

  • Creando un Menu Accordeon con Ajax

    - by jaullo
    Ajax, es uno de los grandes componentes nacidos para utilizar en asp.net que brinda gran cantidad de funcionalidades y potencia nuestras aplicaciones, brindando sencilles y agilidad. Este post, esta dedicado a la creación de un menú tipo accordeon con ajax. Como bien sabemos, para poder utilizar cualquiera de los componentes ajax, es necesario que exista un scriptmanager registrado en nuestra página, el cual será el encargado de manejar nuestros controles. Entonces, lo primero que haremos será crear nuestro script manager.  <asp:ScriptManager ID="ScriptManager1" runat="server">     </asp:ScriptManager> Seguidamente definimos nuestro elemento accordeon y establecemos algunas de sus propiedades básicas:   <cc1:Accordion ID="AccordionCtrl" runat="server"         SelectedIndex="0" HeaderCssClass="accordionHeader"         ContentCssClass="accordionContent" AutoSize="None"         FadeTransitions="true" TransitionDuration="250"     FramesPerSecond="40" Para que nuestro accordeon funcione debemos declarar PANES dentro de el, estos panes serán los encargados de contener los elementos, vinculos o información que deseamos mostrar.   <Panes>                 <cc1:AccordionPane ID="AccordionPane0" runat="server">                     <Header>Matenimiento</Header>                     <Content>                         <li><a href="mypagina.aspx">My página de prueba</a></li>                                                                                          </Content>                 </cc1:AccordionPane> Como vemos podemos declarar tantos accordionPanes como queramos, cada accordionPane representa un elemento de categoría dentro del accordeon. Por útlimo debemos cerrar los elementos panel y accordion que abrirmos inicialmente.  </Panes>  </cc1:Accordion> Nuesto ejemplo finalmente completo debería verse así: <asp:ScriptManager ID="ScriptManager1" runat="server">     </asp:ScriptManager>         <cc1:Accordion ID="AccordionCtrl" runat="server"         SelectedIndex="0" HeaderCssClass="accordionHeader"         ContentCssClass="accordionContent" AutoSize="None"         FadeTransitions="true" TransitionDuration="250"     FramesPerSecond="40" >             <Panes>                 <cc1:AccordionPane ID="AccordionPane0" runat="server">                     <Header>Matenimiento</Header>                     <Content>                         <li><a href="mypagina.aspx">My página de prueba</a></li>                                                                                          </Content>                 </cc1:AccordionPane>                                                             </Panes>         </cc1:Accordion>         De esta forma, nuestro Menu tipo accordeon debería estar funcionando, una forma sencilla y agil de crear un menú en asp.net con Ajax.

    I am trying to use the various tools provided by ec2-ami-tools Eg, ec2-create-snapshot -h .... -K, --private-key KEY Specify KEY as the private key to use. Defaults to the value of the EC2_PRIVATE_KEY environment variable (if set). Overrides the default. -C, --cert CERT Specify CERT as the X509 certificate to use. Defaults to the value of the EC2_CERT environment variable (if set). Overrides the default. -K and -C are two required values, and I cant understand what values are these expecting? If I create a Keypair from Elasticfox, I get only one file to download and a fingerprint. So which of this need to get where?

  • Getting NFS clients to retry mount if NFS server down when client boots

    - by z0mbix
    I have an NFS server that several clients mount. I am using the following in my /etc/exports on the server: /content *(rw,no_root_squash) and on the clients in my /etc/fstab I have: content.prd.domain.tld:/content /content nfs rw,hard,intr 0 0 If the clients boot while the NFS server is down, the share does not get mounted. I read in the NFS man page that the retry defaults should handle this: retry=n The number of minutes to retry an NFS mount operation in the foreground or background before giving up. The default value for forground mounts is 2 minutes. The default value for background mounts is 10000 minutes, which is roughly one week. I have tested this, but it doesn't appear to work. Am I missing something? All servers are RHEL 5.4. Cheers z0mbix

  • How To Speed Up Adding Column To Large Table In Sql Server

    - by Chris
    I want to add a column to a Sql Server table with about 10M rows. I think this query would eventually finish adding the column I want: alter table T add mycol bit not null default 0 but it's been going for several hours already. Is there any shortcut to get a "not null default 0" column inserted into a large table? Or is this inherently really slow? This is Sql Server 2000. Later on I have to do something similar on Sql Server 2008.

  • Can't the NetworkManager applet to appear in the Gnome panel in Ubuntu

    - by Nate
    I have researched this problem extensively and I can't seem to find an answer. In Ubuntu 10.04 LTS, I want to connect to my VPN through the NetworkManager applet. I installed all the network manager packages, including the gnome client. I understand I need to add the "Notification Area" to the panel, which I have done. I checked that the NetworkManager is running: nate@nate-desktop:~$ service network-manager status network-manager start/running, process 763 In /etc/NetworkManager/nm-system-settings.conf, I have added managed=true (don't know if this matters, but I saw it suggested on one forum): nate@nate-desktop:~$ more /etc/NetworkManager/nm-system-settings.conf # This file is installed into /etc/NetworkManager, and is loaded by # NetworkManager by default. To override, specify: '--config file' # during NM startup. This can be done by appending to DAEMON_OPTS in # the file: # # /etc/default/NetworkManager # [main] plugins=ifupdown,keyfile [ifupdown] #managed=false managed=true At this point, it looks like NetworkManager is running but it's not appearing in the NotificationArea of the panel. I don't know what else to try. Any ideas?

  • Apache and MySQL taking all the memory? Maximum connections?

    - by lpfavreau
    I've a had one of our servers going down (network wise) but keeping its uptime (so looks the server is not losing its power) recently. I've asked my hosting company to investigate and I've been told, after investigation, that Apache and MySQL were at all time using 80% of the memory and peaking at 95% and that I might be needing to add some more RAM to the server. One of their justifications to adding more RAM was that I was using the default max connections setting (125 for MySQL and 150 for Apache) and that for handling those 150 simultaneous connections, I would need at least 3Gb of memory instead of the 1Gb I have at the moment. Now, I understand that tweaking the max connections might be better than me leaving the default setting although I didn't feel it was a concern at the moment, having had servers with the same configuration handle more traffic than the current 1 or 2 visitors before the lunch, telling myself I'd tweak it depending on the visits pattern later. I've also always known Apache was more memory hungry under default settings than its competitor such as nginx and lighttpd. Nonetheless, looking at the stats of my machine, I'm trying to see how my hosting company got those numbers. I'm getting: # free -m total used free shared buffers cached Mem: 1000 944 56 0 148 725 -/+ buffers/cache: 71 929 Swap: 1953 0 1953 Which I guess means that yes, the server is reserving around 95% of its memory at the moment but I also thought it meant that only 71 out of the 1000 total were really used by the applications at the moment looking a the buffers/cache row. Also I don't see any swapping: # vmstat 60 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 57612 151704 742596 0 0 1 1 3 11 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 1 1 24 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 2 1 18 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 0 1 13 0 0 100 0 And finally, while requesting a page: top - 08:33:19 up 3 days, 13:11, 2 users, load average: 0.06, 0.02, 0.00 Tasks: 81 total, 1 running, 80 sleeping, 0 stopped, 0 zombie Cpu(s): 1.3%us, 0.3%sy, 0.0%ni, 98.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1024616k total, 976744k used, 47872k free, 151716k buffers Swap: 2000052k total, 0k used, 2000052k free, 742596k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 24914 www-data 20 0 26296 8640 3724 S 2 0.8 0:00.06 apache2 23785 mysql 20 0 125m 18m 5268 S 1 1.9 0:04.54 mysqld 24491 www-data 20 0 25828 7488 3180 S 1 0.7 0:00.02 apache2 1 root 20 0 2844 1688 544 S 0 0.2 0:01.30 init ...

  • C# Adds Optional and Named Arguments

    Earlier this month Microsoft released Visual Studio 2010, the .NET Framework 4.0 (which includes ASP.NET 4.0), and new versions of their core programming languages: C# 4.0 and Visual Basic 10. In designing the latest versions of C# and VB, Microsoft has worked to bring the two languages into closer parity. Certain features available in C# were missing in VB, and vice-a-versa. Last week I wrote about Visual Basic 2010's language enhancements, which include implicit line continuation, auto-implemented properties, and collection initializers - three useful features that were available in previous versions of C#. Similarly, C# 4.0 introduces new features to the C# programming language that were available in earlier versions of Visual Basic, namely optional arguments and named arguments. Optional arguments allow developers to specify default values for one or more arguments to a method. When calling such a method, these optional arguments may be omitted, in which case their default value is used. In a nutshell, optional arguments allow for a more terse syntax for method overloading. Named arguments, on the other hand, improve readability by allowing developers to indicate the name of an argument (along with its value) when calling a method. This article examines how to use optional arguments and named arguments in C# 4.0. Read on to learn more! Read More >

Optional arguments allow developers to specify default values for one or more arguments to a method. When calling such a method, these optional arguments may be omitted, in which case their default value is used. In a nutshell, optional arguments allow for a more terse syntax for method overloading. Named arguments, on the other hand, improve readability by allowing developers to indicate the name of an argument (along with its value) when calling a method. This article examines how to use optional arguments and named arguments in C# 4.0. Read on to learn more!

  • One page using querystring or many folders and pages?

    - by ClarkeyBoy
    I have an application where I have the 'core' code in one folder for which there is a virtual directory in the root, such that I can include any core files using /myApp/core/bla.asp. I then have two folders outside of this with a default.asp which currently use the querystring to define what page should be displayed. One page is for general users, the other will only be accessible to users who have permission to manage users / usergroups / permissions. The core code checks the querystring and then checks the permissions for that user. An example of this as it is now is default.asp?action=view&viewtype=list&objectid=server. I am not worried about SEO as this is an internal app and uses Windows Auth. My question is, is it better the way it is now or would it be better to have something like the following: /server/view/list/ /server/view/?id=123 /server/create/ /server/edit/?id=123 /server/remove/?id=123 In the above folders I would have a home page which defines all the variables which are currently determined by the querystring - in /server/create/ for example, I would define the action as 'create', object name as 'server' and so on. In terms of future development, I really have no idea which method would be best. I think the 2nd method would be best in terms of following what page does what but this is such a huge change to make at this stage that I would really like some opinions, preferably based on experience. PS Sorry if the tags are wrong - I am new to this forum and thought this was a bit too much of a discussion for StackOverflow as that is very much right / wrong answer based. I got the idea SE is more discussion based.

If used in combination with the ADF security expression language and security checks performed in Java, this protection already provides you with fine grained access control that can also be used to secure UI components like buttons and input text field. For example, the EL shown below disables the user profile panel tabs for unauthenticated users: <af:panelTabbed id="pt1" position="above">   ...   <af:showDetailItem        text="User Profile" id="sdi2"                                       disabled="#{!securityContext.authenticated}">   </af:showDetailItem>   ... </af:panelTabbed> The next example disables a panel tab item if the authenticated user is not granted access to the bounded task flow exposed in a region on this tab: <af:panelTabbed id="pt1" position="above">   ...   <af:showDetailItem text="Employees Overview" id="sdi4"                        disabled="#{!securityContext.taskflowViewable         ['/WEB-INF/EmployeeUpdateFlow.xml#EmployeeUpdateFlow']}">   </af:showDetailItem>   ... </af:panelTabbed> Security expressions like shown above allow developers to check the user permission, authentication and role membership status before showing UI components. Similar, using Java, developers can use code like shown below to verify the user authentication status: ADFContext adfContext = ADFContext.getCurrent(); SecurityContext securityCtx = adfContext.getSecurityContext(); boolean userAuthenticated = securityCtx.isAuthenticated(); Note that the Java code lines use the same security context reference that is used with expression language. But is this all that there is? No ! The goal of ADF Security is to enable all ADF developers to build secure web application with JAAS (Java Authentication and Authorization Service). For this, more fine grained protection can be defined using the ResourcePermission, a generic JAAS permission class owned by the Oracle Platform Security Services (OPSS).  Using the ResourcePermission  class, developers can grant permission to functional parts of an application that are not protected by page or task flow security. For example, an application menu allows creating and canceling product shipments to customers. However, only a specific user group - or application role, which is the better way to use ADF Security - is allowed to cancel a shipment. To enforce this rule, a permission is needed that can be used declaratively on the UI to hide a menu entry and programmatically in Java to check the user permission before the action is performed. Note that multiple lines of defense are what you should implement in your application development. Don't just rely on UI protection through hidden or disabled command options. To create menu protection permission for an ADF Security enable application, you choose Application | Secure | Resource Grants from the Oracle JDeveloper menu. The opened editor shows a visual representation of the jazn-data.xml file that is used at design time to define security policies and user identities for testing. An option in the Resource Grants section is to create a new Resource Type. A list of pre-defined types exists for you to create policy definitions for. Many of these pre-defined types use the ResourcePermission class. To create a custom Resource Type, for example to protect application menu functions, you click the green plus icon next to the Resource Type select list. The Create Resource Type editor that opens allows you to add a name for the resource type, a display name that is shown when granting resource permissions and a description. The ResourcePermission class name is already set. In the menu protection sample, you add the following information: Name: MenuProtection Display Name: Menu Protection Description: Permission to grant menu item permissions OK the dialog to close the resource permission creation. To create a resource policy that can be used to check user permissions at runtime, click the green plus icon in the Resources section of the Resource Grants section. In the Create Resource dialog, provide a name for the menu option you want to protect. To protect the cancel shipment menu option, create a resource with the following settings Resource Type: Menu Protection Name: Cancel Shipment Display Name: Cancel Shipment Description: Grant allows user to cancel customer good shipment   A new resource Cancel Shipmentis added to the Resources panel. Initially the resource is not granted to any user, enterprise or application role. To grant the resource, click the green plus icon in the Granted To section, select the Add Application Role option and choose one or more application roles in the opened dialog. Finally, you click the process action to define the policy. Note that permission can have multiple actions that you can grant individually to users and roles. The cancel shipment permission for example could have another action "view" defined to determine which user should see that this option exist and which users don't. To use the cancel shipment permission, select the disabled property on a command item, like af:commandMenuItem and click the arrow icon on the right. From the context menu, choose the Expression Builder entry. Expand the ADF Bindings | securityContext node and click the userGrantedResource option. Hint: You can expand the Description panel below the EL selection panel to see an example of how the grant should look like. The EL that is created needs to be manually edited to show as #{!securityContext.userGrantedResource[               'resourceName=Cancel Shipment;resourceType=MenuProtection;action=process']} OK the dialog so the permission checking EL is added as a value to the disabled property. Running the application and expanding the Shipment menu shows the Cancel Shipments menu item disabled for all users that don't have the custom menu protection resource permission granted. Note: Following the steps listed above, you create a JAAS permission and declaratively configure it for function security in an ADF application. Do you need to understand JAAS for this? No!  This is one of the benefits that you gain from using the ADF development framework. To implement multi lines of defense for your application, the action performed when clicking the enabled "Cancel Shipments" option should also check if the authenticated user is allowed to use process it. For this, code as shown below can be used in a managed bean public void onCancelShipment(ActionEvent actionEvent) {       SecurityContext securityCtx =       ADFContext.getCurrent().getSecurityContext();   //create instance of ResourcePermission(String type, String name,   //String action)   ResourcePermission resourcePermission =     new ResourcePermission("MenuProtection","Cancel Shipment",                            "process");        boolean userHasPermission =          securityCtx.hasPermission(resourcePermission);   if (userHasPermission){       //execute privileged logic here   } } Note: To learn more abput ADF Security, visit http://download.oracle.com/docs/cd/E17904_01/web.1111/b31974/adding_security.htm#BGBGJEAHNote: A monthly summary of OTN Harvest blog postings can be downloaded from ADF Code Corner.

  • Oracle SQL Developer: Fetching SQL Statement Result Sets

    - by thatjeffsmith
    Running queries, browsing tables – you are often faced with many thousands, if not millions, of rows. Most people are happy with looking at the first few rows. But occasionally you need to see more. SQL Developer doesn’t show you all records, all at once. Instead, it brings the records down in ‘chunks,’ or as-needed. How It Works There is a preference that tells SQL Developer how many records to get in a single request, or ‘fetch’ of records. The default is 50… So if I run a query that returns MORE than 50 rows: There’s more than 50 records in this resultset, but we have 50 in the grid to start with. We don’t know how many records are in this result set actually. To show the record count here, we actually go physically query the database with a row count type query. All we know is that the query has finished executing, and that there are rows available to go fetch. It tells us when it’s done. As you scroll through the grid, if you get to record 50 and scroll more, we’ll get 50 more records. Or, you can cheat to get to the ‘bottom’ of the result set. You can ask SQL Developer to just to get all the records at once… Once all the records have been fetched, you’ll see this: All rows fetched! A word of caution There’s a reason we have the default set to 50 and not 1000. Bringing back data can get expensive and heavy. We’ve found the best performance to be found in that 50 to 200 record range.

  • SQL Server Table Polling by Multiple Subscribers

    - by Daniel Hester
    Background Designing Stored Procedures that are safe for multiple subscribers (to call simultaneously) can be challenging.  For example let’s say that you want multiple worker processes to poll a shared work queue that’s encapsulated as a SQL Table. This is a common scenario and through experience you’ll find that you want to use Table Hints to prevent unwanted locking when performing simultaneous queries on the same table. There are three table hints to consider: NOLOCK, READPAST and UPDLOCK. Both NOLOCK and READPAST table hints allow you to SELECT from a table without placing a LOCK on that table. However, SELECTs with the READPAST hint will ignore any records that are locked due to being updated/inserted (or otherwise “dirty”), whereas a SELECT with NOLOCK ignores all locks including dirty reads. For the initial update of the flag (that marks the record as available for subscription) I don’t use the NOLOCK Table Hint because I want to be sensitive to the “active” records in the table and I want to exclude them.  I use an Update Lock (UPDLOCK) in conjunction with a WHERE clause that uses a sub-select with a READPAST Table Hint in order to explicitly lock the records I’m updating (UPDLOCK) but not place a lock on the table when selecting the records that I’m going to update (READPAST). UPDATES should be allowed to lock the rows affected because we’re probably changing a flag on a record so that it is not included in a SELECT from another subscriber. On the UPDATE statement we should explicitly use the UPDLOCK to guard against lock escalation. A SELECT to check for the next record(s) to process can result in a shared read lock being held by more than one subscriber polling the shared work queue (SQL table). It is expected that more than one worker process (or server) might try to process the same new record(s) at the same time. When each process then tries to obtain the update lock, none of them can because another process has a shared read lock in place. Thus without the UPDLOCK hint the result would be a lock escalation deadlock; however with the UPDLOCK hint this condition is mitigated against. Note that using the READPAST table hint requires that you also set the ISOLATION LEVEL of the transaction to be READ COMMITTED (rather than the default of SERIALIZABLE). Guidance In the Stored Procedure that returns records to the multiple subscribers: Perform the UPDATE first. Change the flag that makes the record available to subscribers.  Additionally, you may want to update a LastUpdated datetime field in order to be able to check for records that “got stuck” in an intermediate state or for other auditing purposes. In the UPDATE statement use the (UPDLOCK) Table Hint on the UPDATE statement to prevent lock escalation. In the UPDATE statement also use a WHERE Clause that uses a sub-select with a (READPAST) Table Hint to select the records that you’re going to update. In the UPDATE statement use the OUTPUT clause in conjunction with a Temporary Table to isolate the record(s) that you’ve just updated and intend to return to the subscriber. This is the fastest way to update the record(s) and to get the records’ identifiers within the same operation. Finally do a set-based SELECT on the main Table (using the Temporary Table to identify the records in the set) with either a READPAST or NOLOCK table hint.  Use NOLOCK if there are other processes (besides the multiple subscribers) that might be changing the data that you want to return to the multiple subscribers; or use READPAST if you're sure there are no other processes (besides the multiple subscribers) that might be updating column data in the table for other purposes (e.g. changes to a person’s last name).  NOLOCK is generally the better fit in this part of the scenario. See the following as an example: CREATE PROCEDURE [dbo].[usp_NewCustomersSelect] AS BEGIN -- OVERRIDE THE DEFAULT ISOLATION LEVEL SET TRANSACTION ISOLATION LEVEL READ COMMITTED -- SET NOCOUNT ON SET NOCOUNT ON -- DECLARE TEMP TABLE -- Note that this example uses CustomerId as an identifier; -- you could just use the Identity column Id if that’s all you need. DECLARE @CustomersTempTable TABLE ( CustomerId NVARCHAR(255) ) -- PERFORM UPDATE FIRST -- [Customers] is the name of the table -- [Id] is the Identity Column on the table -- [CustomerId] is the business document key used to identify the -- record globally, i.e. in other systems or across SQL tables -- [Status] is INT or BIT field (if the status is a binary state) -- [LastUpdated] is a datetime field used to record the time of the -- last update UPDATE [Customers] WITH (UPDLOCK) SET [Status] = 1, [LastUpdated] = GETDATE() OUTPUT [INSERTED].[CustomerId] INTO @CustomersTempTable WHERE ([Id] = (SELECT TOP 100 [Id] FROM [Customers] WITH (READPAST) WHERE ([Status] = 0) ORDER BY [Id] ASC)) -- PERFORM SELECT FROM ENTITY TABLE SELECT [C].[CustomerId], [C].[FirstName], [C].[LastName], [C].[Address1], [C].[Address2], [C].[City], [C].[State], [C].[Zip], [C].[ShippingMethod], [C].[Id] FROM [Customers] AS [C] WITH (NOLOCK), @CustomersTempTable AS [TEMP] WHERE ([C].[CustomerId] = [TEMP].[CustomerId]) END In a system that has been designed to have multiple status values for records that need to be processed in the Work Queue it is necessary to have a “Watch Dog” process by which “stale” records in intermediate states (such as “In Progress”) are detected, i.e. a [Status] of 0 = New or Unprocessed; a [Status] of 1 = In Progress; a [Status] of 2 = Processed; etc.. Thus, if you have a business rule that states that the application should only process new records if all of the old records have been processed successfully (or marked as an error), then it will be necessary to build a monitoring process to detect stalled or stale records in the Work Queue, hence the use of the LastUpdated column in the example above. The Status field along with the LastUpdated field can be used as the criteria to detect stalled / stale records. It is possible to put this watchdog logic into the stored procedure above, but I would recommend making it a separate monitoring function. In writing the stored procedure that checks for stale records I would recommend using the same kind of lock semantics as suggested above. The example below looks for records that have been in the “In Progress” state ([Status] = 1) for greater than 60 seconds: CREATE PROCEDURE [dbo].[usp_NewCustomersWatchDog] AS BEGIN -- TO OVERRIDE THE DEFAULT ISOLATION LEVEL SET TRANSACTION ISOLATION LEVEL READ COMMITTED -- SET NOCOUNT ON SET NOCOUNT ON DECLARE @MaxWait int; SET @MaxWait = 60 IF EXISTS (SELECT 1 FROM [dbo].[Customers] WITH (READPAST) WHERE ([Status] = 1) AND (DATEDIFF(s, [LastUpdated], GETDATE()) > @MaxWait)) BEGIN SELECT 1 AS [IsWatchDogError] END ELSE BEGIN SELECT 0 AS [IsWatchDogError] END END Downloads The zip file below contains two SQL scripts: one to create a sample database with the above stored procedures and one to populate the sample database with 10,000 sample records.  I am very grateful to Red-Gate software for their excellent SQL Data Generator tool which enabled me to create these sample records in no time at all.

  • Diamond-square terrain generation problem

    - by kafka
    I've implemented a diamond-square algorithm according to this article: http://www.lighthouse3d.com/opengl/terrain/index.php?mpd2 The problem is that I get these steep cliffs all over the map.
