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.

Good features of Eclipse 3.6 (Eclipse Helios) JDT

Read the Eclipse Galileo features @ http://tips4ufromsony.blogspot.com/2011/10/good-features-of-eclipse35-eclipse.html New options in Open Resource dialog : The Open Resource dialog supports three new features: • Path patterns: If the pattern contains a /, the part before the last / is used to match a path in the workspace: • Relative paths: For example, "./T" matches all files starting with T in the folder of the active editor or selection: • Closer items on top: If the pattern matches many files with the same name, the files that are closer to the currently edited or selected resource are shown on top of the matching items list. MarketPlace : Searching and adding new plugins for Eclipse have always been a challenge. The Eclipse Marketplace makes this much easier – it allows you to not only search a central location of all Eclipse plugins, but also allows you to find the most recent and the most popular plugins.

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...

Oracle no longer generates license keys that are specific to your IP address(es). Oracle now provides generic license files that enable you to fully utilize all of the features for which you are licensed. Please find the ATG License files for different ATG versions @ http://www.oracle.com/us/support/licensecodes/atg/index. @ Oracle Software Delivery Cloud , you can find downloads for all licensable Oracle products –> https://edelivery.oracle.com/ Please find below a screen shot for ATG products download :

Jsp and CSS size limits that web developers need to aware

Here I am listing some erroneous cases that might occur in your web development phase, due to some size restrictions. JSP file size limit : You might get some run time exceptions that the JSP file size limit exceeds. Please find below the reason : In JVM the size of a single JAVA method is limited to 64kb. When the jsp file is converted to Servlet, if the jspservice method's size exceeds the 64kb limit, this exception will occur. Keep in mind that this exception depends on the implementation of the JSP translator, means the same JSP code may give an exception in Tomcat and may run successfully in Weblogic due to the the difference in the logic to built the Servlet methods from JSP. The best way to omit this issue is by using dynamic include.For example, if you are using <%@ include file="sample.jsp" %> (static include), replace this to ...

Eclipse plugin: InstaSearch – for quick search

InstaSearch is an Eclipse plug-in for performing quick and advanced search of workspace files. This will index the files and when you search for some file contents, it will look with in this index and the search results will be faster, just like the Goolge instant search. It uses Lucene ( http://lucene.apache.org/ ) for indexing and fast searching of files in the workspace. Each search result file then can be previewed using few most matching and relevant lines. A double-click on the match leads to the matching line in the file. Main Features Instantly shows search results Shows a preview using relevant lines Periodically updates the index Matches partial words (e.g. case in CamelCase) Opens and highlights matches in files Searches JAR source attachments Supports filtering by extension/project/working set Download / Installation In Eclipse Helios (3.6) please install using the Eclipse Marketplace from the Help menu http://marketplace.eclipse.org/s...
