ATG Search - search engine tuning settings

In this blog, I am going to list the best tuning settings for ATG Search engine.

The AESoapConfig.xml, AESoapWaspConfig.xml  and AEConfig.xml are the xmls referred below and you can find it @  <ATG_DIR>\<Searchx.x>\SearchEngine\<operating_system>\bin\ folder.

(1)  Make sure that the AESoapConfig.xml's rwTimeout is less than or equal to routing's readTimeoutMs. You could find the routing's readTimeoutMs @ atg\search\routing\SearchEngineService component.

              rwTimeout is the  length of time in seconds to wait before a read or write operation times out on an active connection. The number can be decreased to improve performance. However, a value that is too low could cause slow connections to be prematurely closed.

(2)  Adjust the number of engine threads to match the number of CPUs available to the engine. Note that the minimal value for maxThreads and maxSpareThreads is 2, which applies to running with 1 CPU.  However, it is recommended to run with more than one CPU.
      a) Set MaxThreads in AEConfig.xml to number of CPU's
      b) Set maxSpareThreads in AESoapWaspConfig.xml to number of CPU's

             maxThreads is the number of requests you can process simultaneously, and this generally should be the number of CPU's available to the engine. If this is higher than the CPUs, the engine will bog down, with slower response times.
             maxSpareThreads is the number of  worker threads to process requests simultaneously, generally this should be the same as MaxThreads.

(3)  Disable the the keep-alive/connection reuse setting
       a) Set reuseCount=0
   
            reuseCount is the number of requests that may be accepted using the same connection. The number can be increased to reduce the frequency of opening new connections and improve performance. However, a value that is too high could prevent new connections from being accepted. A value of 0 disables connection reuse. This applies to HTTP 1.1 only.

ATG Search Indexing - behind the scene steps explained

Read more about the search indexing @  http://tips4ufromsony.blogspot.com/2011/11/atg-search-architectural-flow-search.html ATG search indexing involves index file creation, deploying and copying the index file to the search engine's box. The steps can be divided into Initial stage, Preparing Content, Indexing and Deploying. Please find below the detailed analysis of each step. 1. Initial stage:        a. Check whether the folder deployshare configured correctly @ LaunchingService.deployShare  ( \atg\search\routing\LaunchingService.deployShare ). Lets assume that it is configured to \Search2007.1\SearchEngine\i686-win32-vc71\buildedIndexFiles.        b. Lets assume that the index file folder ( \Search2007.1\SearchEngine\i686-win32-vc71\indexFiles)  has the following segments (folders) currently :                     66900...

Eclipse Kepler - good features of Eclipse 4.3 ( Eclipse Kepler ) JDT / Workbench

Detached windows with sash When you detach a view or editor into its own separate window, it now has all the capabilities of a normal workbench window. They now support multiple stacks of views separated by sashes with arbitrary layouts. The detached parts will remain synchronized with the master window that they were detached from. This is especially handy for people developing with two or more monitors, so they can spread views across several monitors and keep them synchronized. Import nested projects The Import Projects wizard now has an option to continue searching for projects to import recursively within any project it finds. This allows you to import physically nested projects at the same time. Open Resource dialog enhancements The Open Resource (Ctrl+Shift+R) dialog now offers direct access to the Show In and Open With menus via drop-down buttons. On platforms that support mnemonics, the buttons are also accessible via Alt+W and Alt+H. Whole word option...

ATG - how to create and deploy a new atg module

ATG products are packaged as a number of separate application modules. Application modules exist in the ATG installation as a set of directories defined by a manifest file. To create a new module, follow the below steps : Create a module directory within your ATG installation.  Create a META-INF directory within the module directory. Note that this directory must be named META-INF.  Create a manifest file named MANIFEST.MF and include it in the META-INF directory for the module. The manifest contains the meta-data describing the module. A module located at <ATG2007.1dir>/MyModule is named MyModule and a module located at <ATG2007.1dir>/CustomModules/MyModule is named CustomModules.MyModule. Within the subdirectory that holds the module, any number of files may reside in any desired order. These files are the module resources (EAR files for J2EE applications, WAR files for web applications, EJB-JAR files for Enterprise JavaBeans, JAR files of Java class...
