  • Weblogic domain scale up using EM Grid Control 11gR1

    - by dmitry.nefedkin(at)oracle.com
    As you know a weblogic domain consists of set of servers running independently or in a cluster mode, sharing the distributed resources. And in most environments weblogic  cluster consists of multiple managed servers running simultaneously and working together to provide increased scalability and reliability.  These servers can run on the same machine, or be located on different machines.  It's a common task to increase a cluster's capacity by adding new machines to the cluster to host the new server instances.  You can do it by manually installing weblogic binaries to the new host and use pack/unpack commands to add a managed server to this new host.  But with Enterprise Manager Grid Control 11gR1 (EMGC) there is  another way - Fusion Middleware Domain Scale Up  procedure. I'm going to show you how it works.Here is a picture of  my medrec_oradb weblogic domain, what is registered in EMGC. It contains an admin server and a cluster MedRecCluster with  the single managed server MS1. Both admin and managed servers are on the same host oel46-vmware, it's a virtual machine with OEL 4.6 that runs inside our Oracle VM infrastructure.  And here are the application deployments, note that couple of applications are deployed to the cluster.First of all I have to prepare a new machine that will host new managed sever of my cluster. I created new VM with OEL 5.4 using the corresponding Oracle VM template available in Oracle E-Delivery site for Oracle Linux and Oracle VM and named it wls1032. Next step is to install Oracle EM Grid Control 11gR1 Agent to this new host.  You can download it from the OTN page and install it manually,  or you can use Agent Installation Deployment procedure available in EMGC  (Deployments->Agent Installation->Install Agent). Anyway, when you agent is up and running on the new machine, you will see it in EMGC Console in the Targets->Hosts subtab.Now we are ready to scale up our weblogic domain. Click the Deployments tab in Oracle Enterprise Manager Grid Control, and then click Deployment Procedure. Select a Fusion Middleware Domain Scale Up procedure from the list, and click Schedule Deployment. The first page of the FMW Domain Scale Up Wizard is displayed and you can proceed with the deployment process.Select the domain from list, enter the working directory on the admin server host, and also fill the weblogic credentials for the administration server console and the OS credentials for the  admin server host.  Click Next button.  The next step allows you to configure you domain, to add a new manager server to the cluster you should select the cluster in the tree and click Add Server button. Select the newly added server in a tree, choose the target host and  enter the configuration details of your managed server. You can also add new machine and node manager details.  Please note that you cannot change the values in  Domain Location and Fusion Middleware Home fields, so these locations on the target host will be the same as for the admin server host.   Working directory on the target host should have enough free space to store FMW home binaries and domain configuration files.  In my experience the working directories should have at least 3 Gb of free space.  The last thing you should fill is the OS credentials for the target host. The next steps allows you to schedule the execution of the procedure, it is started immediately in my example. The last step is just a review the configuration for the domain scale up. Click Submit to launch the process. You can track the status of the procedure execution by selecting Deployments->Deployment Procedures->Procedure Completion Status in the EMGC Console.As you can see in the picture below, the procedure consists of the many steps, and I'm going to share my experience about the issues that I had at some of the steps. Please keep in mind that you can always continue the execution from the last successfully completed step by clicking Retry button.Check OUI Prerequisites  step may fail if the target host does  not pass prerequisites checks for Weblogic Server installation such as amount of RAM, linux packages installed, etc. Create FMW Clone Archive step may fail if you do not have enough free space in the working directory on the administration server host.Transfer cloning archive to targets  step  may fail if the EMGC agents on the admin server host or on target host are not secured.   You should secure the agent by issuing ./emctl secure agent  command from $AGENT_HOME/bin directory and entering the agent registration password.Both Transfer cloning archive to targets and Apply Clone at target hosts steps may fail if you do not have enough free space in the working directory on the target host. The most complicated issue I had on the Run Inventory Collection  step. The step failed and I noticed that the agent on the target server is also failed with the following error in the $AGENT_HOME/sysman/log/emagent.trc  log file:2010-12-28 11:50:34,310 Thread-2838952848 ERROR upload: Failed to upload file A0000008.xml: Fatal Error.Response received: 500|ORA-20603: The timezone of the multiagent target (/Farm_Localhost_MedRec_medrec_oradb/medrec_oradb,weblogic_domain)is not consistent with the timezone (America/Los_Angeles) reported by other agents.2010-12-28 11:50:34,310 Thread-2838952848 ERROR upload: 1 Failure(s) in a row or XML error for A0000008.xml, retcode = -6, we give up2010-12-28 11:50:35,552 Thread-2838952848 WARN  upload: FxferSend: received fatal error in header from repository: https://oel46-vmware:1159/em/uploadFATAL_ERROR::500|ORA-20603: The timezone of the multiagent target (/Farm_Localhost_MedRec_medrec_oradb/medrec_oradb,weblogic_domain)is not consistent with the timezone (America/Los_Angeles) reported by other agents.2010-12-28 11:50:35,552 Thread-2838952848 ERROR upload: number of fatal error exceeds the limit 32010-12-28 11:50:35,552 Thread-2838952848 ERROR upload: agent will shutdown now2010-12-28 11:50:35,552 Thread-2838952848 ERROR : Signalled to Exit with status 55.

This powerful feature of the Enterprise Manager Grid Control  is a part of  the WebLogic Server Management Pack Enterprise Edition.

  • How to use JNI, but only when available for current platform?

    - by Mecki
    What is the common way (or best practice) to optionally use JNI? E.g. I have a Java class and this class is 100% pure Java, so it can run on all platforms. However, on some platforms I'd like to speed up some heavy calculations using JNI - which works fine. Unfortunately I cannot support any existing Java platform in the world. So I guess it is fine to initially only support the big three: Linux, Windows, Mac OS X. So what I'd like to do is to use JNI on those three platforms and use the 100% pure Java version on all other platforms. Now I can think of various ways how to do that (loading class dynamically for example and either loading the JNI class or the pure Java one), but thinking that this is a common issue that thousands of projects had to solve in the past for sure, I'm really surprised to not find any documentation or references to the question how to solve this most elegantly or effectively.

  • Pixel Shader, YUV-RGB Conversion failing

    - by TomTom
    I am tasked with playing back a video hthat comes in in a YUV format as an overlay in a larger game. I am not a specialist in Direct3d, so I am struggling. I managed to get a shader working and am rendering 3 textures (Y, V, U). Sadly I am totally unable to get anything like a decent image. Documentation is also failing me. I am currently loading the different data planes (Y,V,U) in three different textures: m_Textures = new Texture[3]; // Y Plane m_Textures[0] = new Texture(m_Device, w, h, 1, Usage.None, Format.L8, Pool.Managed); // V Plane m_Textures[1] = new Texture(m_Device, w2, h2, 1, Usage.None, Format.L8, Pool.Managed); // U Plane m_Textures[2] = new Texture(m_Device, w2, h2, 1, Usage.None, Format.L8, Pool.Managed); When I am rendering them as R, G and B respectively with the following code: float4 Pixel( float2 texCoord: TEXCOORD0) : COLOR0 { float y = tex2D (ytexture, texCoord); float v = tex2D (vtexture, texCoord); float u = tex2D (utexture, texCoord); //R = Y + 1.140 (V -128) //G = Y - 0.395 (U-128) - 0.581 (V-128) //B = Y + 2.028 (U-128) float r = y; //y + 1.140 * v; float g = v; //y - 0.395 * u - 0.581 * v; float b = u; //y + 2.028 * u; float4 result; result.a = 255; result.r = r; //clamp (r, 0, 255); result.g = g; //clamp (g, 0, 255); result.b = b; //clamp (b, 0, 255); return result; } Then the resulting image is - quite funny. I can see the image, but colors are totally distorted, as it should be. The formula I should apply shows up in the comment of the pixel shader, but when I do it, the resulting image is pretty brutally magenta only. This gets me to the question - when I read out an L8 texture into a float, with float y = tex2D (ytexture, texCoord); what is the range of values? The "origin" values are 1 byte, 0 to 255, and the forum I have assumes this. Naturally I am totally off when the values returned are somehow normalized. My Clamp operation at the end also will fail if for example colors in a pixel shader are normalized 0 to 1. Anyone an idea how that works? Please point me also to documentation - I have not found anything in this regard.

  • OracleServiceBus+SOA in same server

    - by Manoj Neelapu
    Oracle Service Bus 11gR1 (11.1.1.3) supports running in same JVM as SOA. This tutorial covers on how to do create domain in of SOA+OSB combined to run in single JVM .For this tutorial we will use a flavor  WebLogic installer bundled with both OEPE and coherence components (eg oepe111150_wls1033_win32.exe). WebLogic installer bundled with coherence and OEPE components can be seen in the screen shot.Oracle Service Bus 11gR1 (11.1.1.3) has built-in caching support for Business Services using coherence. Because of this we will have to install coherence before  installing OSB.  To get SOAand OSB running in the same domain, we have to install the SOA and OSB on the above ORACLE_HOME. After installation we should see both the SOA and OSB homes has highlighted in red.We could also see the coherence components which is mandatory for OSB and optional OEPE also installed.                     Now we will execute RCU(ofm_rcu_win_11.1.1.3.0_disk1_1of1) to install the schema for SOA and OSB. New RCU contains OSB tables (WLI_QS_REPORT_DATA , WLI_QS_REPORT_ATTRIBUTE) gets loaded as part of SOAINFRA schema  After this step we will have to create soa+osb domain using config wizard. It is located under $WEBLOGIC_HOME\common\bin\config.* (.cmd or .sh as per your platform) .While creating a domain we will select options for SOA Suite  and Oracle Service Bus Extension-All Domain Topologies.We can also bundle Enterprise Manager in the same installation or in a different server. Here in this case we will use the enterprise manager in the same domain. So we selected the Enterprise Manager component also. There is another option for OSB  Oracle Service Bus Extension-Single server Domain Topology. This topology is for users who want to use OSB in single server configuration. Currently SOA doesn't support single server topology. So this topology cannot be used with SOA domain but can only be used for stand alone OSB installations.We can continue with domain configuration till we reach the below screen. Following steps are mandatory if we want to have the SOA and OSB run in same JVMwe should select Managed Server, Clusters and Machines as shown below   After this selection you should see a screen with two servers One managed server for OSB and one managed for SOA.  Since we would like to have both the servers in one managed server (one JVM) we will have to do one

  • Back-sliding into Unmanaged Code

    - by Laila
    It is difficult to write about Microsoft's ambivalence to .NET without mentioning clichés about dog food.  In case you've been away a long time, you'll remember that Microsoft surprised everyone with the speed and energy with which it introduced and evangelised the .NET Framework for managed code. There was good reason for this. Once it became obvious to all that it had sleepwalked into third place as a provider of development languages, behind Borland and Sun, it reacted quickly to attract the best talent in the industry to produce a windows version of the Java runtime, with Bounds-checking, Automatic Garbage collection, structures exception handling and common data types. To develop applications for this managed runtime, it produced several excellent languages, and more are being provided. The only thing Microsoft ever got wrong was to give it a stupid name. The logical step for Microsoft would be to base the entire operating system on the .NET framework, and to re-engineer its own applications. In 2002, Bill Gates, then Microsoft Chairman and Chief Software Architect said about their plans for .NET, "This is a long-term approach. These things don't happen overnight." Now, eight years later, we're still waiting for signs of the 'long-term approach'. Microsoft's vision of an entirely managed operating system has subsided since the Vista fiasco, but stays alive yet dormant as Midori, still being developed by Microsoft Research. This is an Internet-centric fork of the singularity operating system, a research project started in 2003 to build a highly-dependable operating system in which the kernel, device drivers, and applications are all written in managed code. Midori is predicated on the prevalence of connected systems, with provisions for distributed concurrency where application components exist 'in the cloud', and supports a programming model that can tolerate cancellation, intermittent connectivity and latency. It features an entirely new security model that sandboxes applications for increased security. So have Microsoft converted its existing applications to the .NET framework? It seems not. What Windows applications can run on Mono? Very few, it seems. We all thought that .NET spelt the end of DLL Hell and the need for COM interop, but it looks as if Bill Gates' idea of 'not overnight' might stretch to a decade or more. The Operating System has shown only minimal signs of migrating to .NET. Even where the use of .NET has come to dominate, when used for server applications with IIS, IIS itself is still entirely developed in unmanaged code. This is an irritation to Microsoft's greatest supporters who committed themselves fully to the NET framework, only to find parts of the Ambivalent Microsoft Empire quietly backsliding into unmanaged code and the awful C++. It is a strategic mistake that the invigorated Apple didn't make with the Mac OS X Architecture. Cheers, Laila

  • WebLogic Server Weekly for March 26th, 2012: WLS 1211 Update, Java 7 Certification, Galleria, WebLogic for DBAs, REST and Enterprise Architecture, Singleton Services

    - by Steve Button
    WebLogic Server 12c Certified with Java 7 for Production Use WebLogic Server 12c (12.1.1) has been certified with JDK 7 for development usage since December and we have now completed JDK 7 certification for use with production systems. In doing so, we have updated the WebLogic Server 12c (12.1.1) distributions incorporating fixes associated with JDK 7 support as well as some bundled patches that address several issues that have been discovered since the initial release. These updated distributions are available for download from OTN and will be beneficial for all WebLogic Server 12c (12.1.1) users in general. What's New Release Notes Download Here! Updated Oracle WebLogic Server 12.1.1.0 distribution Never one to miss a trick, Markus Eisele was one of the first to notice the WebLogic Server 12c update and post a blog about it. Sources told me that as of Friday last week you have an updated version of WebLogic Server 12c on OTN. http://blog.eisele.net/2012/03/updated-oracle-weblogic-server-12110.html Using WebLogic Server 12c with Java 7 - Video To illustrate the use of Java 7 with WebLogic Server 12c, I put together a screen cam showing the creation of a domain using Java 7 and then build and deploy a simple web application that uses Java 7 syntax to show it working. Ireland OUG Presentation: WebLogic for DBAs Simon Haslam posted his slides from a presentation he gave Dublin on 21/3/12 at the OUG Ireland conference. In this presentation, he explains the core concepts and ideas behind WebLogic Server, walks through an installation and offers some tips and common gotcha's to avoid. Simon also covers some aspects of installing and use Enterprise Manager 12c. Note: I usually install the JVM and use the generic .jar installer rather than using an installer bundled with a JVM. http://www.slideshare.net/Veriton/weblogic-for-dbas-10h Slightly Retro: Jeff West on Enterprise Architecure and REST In this weeks flashback, we look at Jeff West's blog from early 2011 where he provides some thoughtful opinions on enterprise architecture and innovation, then jumps into his views on REST. After I progressed in my career and did more team-leading and architecture type roles I was ‘educated’ on what it meant to have Asynchronous and Long-Running processes as part of your Enterprise Application architecture. If I had a synchronous process then I needed a thread available to service the request and then provide the response. https://blogs.oracle.com/jeffwest/entry/weblogic_integration_wli_web_services_and_soap_and_rest_part_1 Starting Managed Servers without an Administration Server using Node Manager and WLST Blogger weblogic-tips shows how to start a managed server without going through the Administration Server, using the Node Manager and WLST. Connect WLST to a Node Manager by entering the nmConnect command. http://www.weblogic-tips.com/2012/02/18/starting-managed-servers-without-an-administration-server-using-node-manager-and-wlst/ Using WebLogic Server Singleton Services WebLogic Server has supported the notion of a Singleton Service for a number of releases, in which WebLogic Server will maintain a single instance of a configured singleton service on one managed server within a cluster. This blog demonstrates how the singleton service can be accessed and used from applications deployed on the cluster. http://buttso.blogspot.com.au/2012/03/weblogic-server-singleton-services.html

  • Slicing the EDG

    - by Antony Reynolds
    Different SOA Domain Configurations In this blog entry I would like to introduce three different configurations for a SOA environment.  I have omitted load balancers and OTD/OHS as they introduce a whole new round of discussion.  For each possible deployment architecture I have identified some of the advantages. Super Domain This is a single EDG style domain for everything needed for SOA/OSB.   It extends the standard EDG slightly but otherwise assumes a single “super” domain. This is basically the SOA EDG.  I have broken out JMS servers and Coherence servers to improve scalability and reduce dependencies. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if rest of domain is unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service. Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Benefits Single Administration Point (1 Admin Server) Closely follows EDG with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Drawbacks Patching is an all or nothing affair. Startup time for SOA may be slow if large number of composites deployed. Multiple Domains This extends the EDG into multiple domains, allowing separate management and update of these domains.  I see this type of configuration quite often with customers, although some don't have OWSM, others don't have separate Coherence etc. SOA & BAM are kept in the same domain as little benefit is obtained by separating them. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if other domains are unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service. Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Benefits Follows EDG but in separate domains and with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Patch lifecycle of OSB/SOA/JMS are no longer lock stepped. JMS may be kept running independently of other domains allowing applications to insert messages fro later consumption by SOA/OSB. OSB may be kept running independent of other domains, allowing service virtualization to continue independent of other domains availability. All domains use same OWSM policy store (MDS-WSM). Drawbacks Multiple domains to manage and configure. Multiple Admin servers (single view requires use of Grid Control) Multiple Admin servers/WSM clusters waste resources. Additional homes needed to enjoy benefits of separate patching. Cross domain trust needs setting up to simplify cross domain interactions. Startup time for SOA may be slow if large number of composites deployed. Shared Service Environment This model extends the previous multiple domain arrangement to provide a true shared service environment.This extends the previous model by allowing multiple additional SOA domains and/or other domains to take advantage of the shared services.  Only one non-shared domain is shown, but there could be multiple, allowing groups of applications to share patching independent of other application groups. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if other domains are unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Shared SOA Domain hosts Human Workflow Tasks BAM Common "utility" composites Single OSB domain provides "Enterprise Service Bus" All domains use same OWSM policy store (MDS-WSM) Benefits Follows EDG but in separate domains and with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Patch lifecycle of OSB/SOA/JMS are no longer lock stepped. JMS may be kept running independently of other domains allowing applications to insert messages fro later consumption by SOA/OSB. OSB may be kept running independent of other domains, allowing service virtualization to continue independent of other domains availability. All domains use same OWSM policy store (MDS-WSM). Supports large numbers of deployed composites in multiple domains. Single URL for Human Workflow end users. Single URL for BAM end users. Drawbacks Multiple domains to manage and configure. Multiple Admin servers (single view requires use of Grid Control) Multiple Admin servers/WSM clusters waste resources. Additional homes needed to enjoy benefits of separate patching. Cross domain trust needs setting up to simplify cross domain interactions. Human Workflow needs to be specially configured to point to shared services domain. Summary The alternatives in this blog allow for patching to have different impacts, depending on the model chosen.  Each organization must decide the tradeoffs for itself.  One extreme is to go for the shared services model and have one domain per SOA application.  This requires a lot of administration of the multiple domains.  The other extreme is to have a single super domain.  This makes the entire enterprise susceptible to an outage at the same time due to patching or other domain level changes.  Hopefully this blog will help your organization choose the right model for you.

  • Dump debugging with Parallel Stacks

    One of the areas where we fixed many bugs for Beta2 in our parallel debugging windows is with regards to managed dump debugging. So it was really cool to see Tess use the Parallel Stacks window in that scenario in her video demo with Scott.Other than the neat ability to open managed dumps in VS2010, Parallel Stacks was the only debugging feature she needed for diagnosing the issue! Check out the video, definitely worth 10 minutes of your time. Comments about this post welcome at the original blog.

On my localhost, it sure does .. and contains a large list of ascx controls. But they don't exist on my live server. So ... what is going on here? Can anyone please help? Oh :) Before someone suggests I create those two folders and even stick a random file in those folders .. and have some random text in those random files .. i've done that and it doesn't seem to work, still :( Please Help !

  • SWT Layout for absolute positioning with minimal-spanning composites

    - by pure.equal
    Hi, I'm writing a DND-editor where I can position elemtents (like buttons, images ...) freely via absolute positioning. Every element has a parent composite. These composites should span/grasp/embrace every element they contain. There can be two or more elements in the same composite and a composite can contain another composite. This image shows how it should look like. To achive this I wrote a custom layoutmanager: import org.eclipse.swt.SWT; import org.eclipse.swt.graphics.Point; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Control; import org.eclipse.swt.widgets.Layout; public class SpanLayout extends Layout { Point[] sizes; int calcedHeight, calcedWidth, calcedX, calcedY; Point[] positions; /* * (non-Javadoc) * * @see * org.eclipse.swt.widgets.Layout#computeSize(org.eclipse.swt.widgets.Composite * , int, int, boolean) * * A composite calls computeSize() on its associated layout to determine the * minimum size it should occupy, while still holding all its child controls * at their minimum sizes. */ @Override protected Point computeSize(Composite composite, int wHint, int hHint, boolean flushCache) { int width = wHint, height = hHint; if (wHint == SWT.DEFAULT) width = composite.getBounds().width; if (hHint == SWT.DEFAULT) height = composite.getBounds().height; return new Point(width, height); } /* * (non-Javadoc) * * @see * org.eclipse.swt.widgets.Layout#layout(org.eclipse.swt.widgets.Composite, * boolean) * * Calculates the positions and sizes for the children of the passed * Composite, then places them accordingly by calling setBounds() on each * one. */ @Override protected void layout(Composite composite, boolean flushCache) { Control children[] = composite.getChildren(); for (int i = 0; i < children.length; i++) { calcedX = calcX(children[i]); calcedY = calcY(children[i]); calcedHeight = calcHeight(children[i]) - calcedY; calcedWidth = calcWidth(children[i]) - calcedX; if (composite instanceof Composite) { calcedX = calcedX - composite.getLocation().x; calcedY = calcedY - composite.getLocation().y; } children[i].setBounds(calcedX, calcedY, calcedWidth, calcedHeight); } } private int calcHeight(Control control) { int maximum = 0; if (control instanceof Composite) { if (((Composite) control).getChildren().length > 0) { for (Control child : ((Composite) control).getChildren()) { int calculatedHeight = calcHeight(child); if (calculatedHeight > maximum) { maximum = calculatedHeight; } } return maximum; } } return control.computeSize(SWT.DEFAULT, SWT.DEFAULT, true).y + control.getLocation().y; } private int calcWidth(Control control) { int maximum = 0; if (control instanceof Composite) { if (((Composite) control).getChildren().length > 0) { for (Control child : ((Composite) control).getChildren()) { int calculatedWidth = calcWidth(child); if (calculatedWidth > maximum) { maximum = calculatedWidth; } } return maximum; } } return control.computeSize(SWT.DEFAULT, SWT.DEFAULT, true).x + control.getLocation().x; } private int calcX(Control control) { int minimum = Integer.MAX_VALUE; if (control instanceof Composite) { if (((Composite) control).getChildren().length > 0) { for (Control child : ((Composite) control).getChildren()) { int calculatedX = calcX(child); if (calculatedX < minimum) { minimum = calculatedX; } } return minimum; } } return control.getLocation().x; } private int calcY(Control control) { int minimum = Integer.MAX_VALUE; if (control instanceof Composite) { if (((Composite) control).getChildren().length > 0) { for (Control child : ((Composite) control).getChildren()) { int calculatedY = calcY(child); if (calculatedY < minimum) { minimum = calculatedY; } } return minimum; } } return control.getLocation().y; } } The problem with it is that it always positions the composite at the position (0,0). This is because it tries to change the absolute positioning into a relative one. Lets say I position a image at position (100,100) and one at (200,200). Then it has to calculate the location of the composite to be at (100,100) and spanning the one at (200,200). But as all child positions are relative to their parents I have to change the positions of the children to remove the 100px offset of the parent. When the layout gets updated it moves everything to the top-left corner (as seen in the image) because the position of the image is not (100,100) but (0,0) since I tried to remove the 100px offset of the partent. Where is my error in reasoning? Is this maybe a totally wrong approach? Is there maybe an other way to achive the desired behavior? Thanks in advance! Best regards, Ed

  • How to pass a random User/Pass (for Basic Authentication) with JMeter?

    - by Pure.Krome
    Hi folks, I'm using JMeter to stress test an API. I've got Basic Authentication set up - seems to be working great. Now, i'm trying to randomize the credentials that JMeter passes across the wire. So, there's two ways I know I can do this. Add a custom HTTP Header (via an HTTP Header Manager Element) and set then value to the random fields (ie. something I've read in from a csv file) Use the HTTP Authorization Manager Element and pass in the username and password there. Now, if I try and use method (1) above, I need to create the following header/data :- Authorization: Basic <some Base64 encoded string in the format username:password> eg. Authorization: Basic OnVzZXIxOnBhc3Mx Kewl. simple. BUT that header value is not getting passed across the wire :( I can add any other header type and it's passed across the wire.. hmm .. ok then .. lets try method (2). Now that works .. but I can only hardcode in the username & password. I can't see how I can pass in a username VARIABLE (ie. ${usernmae} ) or a password VARIABLE (ie. ${password} ).... If it's hardcoded, then the server correctly replies with the correct page/data. so .. can someone please help?

  • Unable to read in my custom .config section

    - by Pure.Krome
    Hi folks, NOTE: this is very very similar to this SO question, but I need some more help. i'm trying to make the following section in my .config file, but i get an exception when trying to access this section. .config file <configSections> <section name="foos" type="Ackbar.Mvc.Models.Foo.FooCollection, Ackbar.Mvc" requirePermission="false"/> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler" requirePermission="false" /> </configSections> <foos> <add name="aaa" something="zzz"/> <add name="bbb" something="yyy"/> <add name="ccc" something="xxx"/> </foos> Ok, so this means i need to make two classes classes public class FooCollection : ConfigurationElementCollection { ... with my custom overrides, etc. ... } and public class FooElement : ConfigurationElement { [ConfigurationProperty("Name", IsRequired = true)] public string Name { .. } [ConfigurationProperty("Something ", IsRequired = true)] public string Something { .. } [ConfigurationProperty("IsDefault ", IsRequired = false, DefaultValue = false)] public bool IsDefault { .. } } Kewl. Now, when i do the following .... var whatever = ConfigurationManager.GetSection("foos") is throws the following exception :- An error occurred creating the configuration section handler for foos: Type 'Ackbar.Mvc.Models.Foos.FooCollection' does not inherit from 'System.Configuration.IConfigurationSectionHandler'. Can someone please help me? I don't want to wrap the collection INSIDE a parent section. Cheers :)

  • How to invalidate the OutputCache in a webfarm?

    - by Pure.Krome
    Hi folks, i've got a website that uses OutputCache attribute to cache pages. Works great. Now, I'm in the middle of R&D'ing scaling up this site to be in a web farm. Along with the usual suspects for webfarm pain ... I've noticed (pretty quickly/obviously) that the OutputCache from Server_A doesn't invalidate the OutputCache from Server_B .. if a try and invalidate a single server's OutputCache. This makes total sense - how can S_A 'tell' S_B to invalidate when they are physically 2 seperate machines, etc? So - what are our options? Velocity? I understand this will move the caching to a different layer .. which means that the final result (output) will always be required to be determined .. as opposed to the OutputCache whic remembers the final output content (yes, varby gives different versions, etc.. which is totally fine). So even though the poco or business objects are all sync'd, there's still that last rendering effort required (even if it's tiny .. compared to the effort to generate/sync business objects). So yeah .. not sure of the options here and what other people do?

  • What is wrong with my Basic Authentication in my Browser?

    - by Pure.Krome
    Hi folks, i'm trying to goto the following url :- http://user1:pass1@localhost:1234/api/users?format=xml nothing to complex. Notice how i've got the username/password in the url? this, i believe, is for basic authentication. When I do that, the Request Headers are MISSING the 'Authorize' header. Er... that's not right :( I have anonymous authentication only setup on the site. I don't want to have anon off and basic turned on .. because not all of the site requires basic.. only a few action methods. So .. why is this not working? Is this something to do with the fact my code is not sending a 401 challenge or some crap? For What It's Worth, my site is ASP.NET MVC1 running on IIS7 (and the same thing happens when i run it on cassini). Update: If this is an illegal way of calling a resource using basic auth (ala security flaw) .. then is this possible to do, for an ASP.NET MVC website .. per action method (and not the entire site, per say)?

  • How can i Execute a Controller's ActionMethod programatically?

    - by Pure.Krome
    Hi folks, I'm trying to execute a controller's Action Method programatically and I'm not sure how. Scenario: When my ControllerFactory fails to find the controller, I wish it to manually execute a single action method which i have on a simple, custom controller. I don't want to rely on using any route data to determine the controller/method .. because that route might not have been wired up. Eg. // NOTE: Error handling removed from this example. public class MyControllerFactory : DefaultControllerFactory { protected override IController GetControllerInstance(Type controllerType) { IController result = null; // Try and load the controller, based on the controllerType argument. // ... snip // Did we retrieve a controller? if (controller == null) { result = new MyCustomController(); ((MyCustomController)result).Execute404NotFound(); // <-- HERE! } return result; } } .. and that method is .. public static void Execute404NotFound(this Controller controller) { result = new 404NotFound(); // Setup any ViewData.Model stuff. result.ExecuteResult(controller.ControllerContext); // <-- RUNTIME // ERROR's HERE } Now, when I run the controller factory fails to find a controller, i then manually create my own basic controller. I then call the extension method 'Execute404NotFound' on this controller instance. That's fine .. until it runs the ExecuteResult(..) method. Why? the controller has no ControllerContext data. As such, the ExecuteResult crashes because it requires some ControllerContext. So - can someone out there help me? see what I'm doing wrong. Remember - i'm trying to get my controller factory to manually / programmatically call a method on a controller which of course would return an ActionResult. Please help!
