JBoss - how to take thread dumps


Following are the different options in JBoss to take the thread dump.

1. Using JBoss jmx-console :  Got to http://localhost:8080/jmx-console and search for the mbean "serverInfo" and click on that link. Click the invoke mbean operation under listThreaddump() method. This will give you the current snapshot of threads which are running in your JBoss jvm.

2. By using twiddle :  In the commnad promt go to <JBOSS-HOME>/bin and run the command twiddle.bat invoke "jboss.system:type=ServerInfo" listThreadDump > threadDump.html and you could find the threadDump.html with the JBoss thread dump.

3. Using "Interrupt" signal : Use kill -3 <process-id> to generate thread dump. You will find the thread dumps in server logs.

ATG Search architectural flow : Search and Index

I would like to explain the high level ATG Search implementation architecture ( for an online store) through the above diagram. In this diagram 1.x denotes the search functionality and 2.x denotes the indexing functionality. I have given JBoss as the application server. Physical Boxes and Application Servers in the diagram ( as recommended by ATG )  : Estore ( Commerce ) Box --> The box with the estore/site ear (with the site JSPs and Java codes). Search Engine Box --> The box with the search engine application running. Indexing Engine Box --> The box with the indexing engine application running. CA (Content Administration) Box --> The box with the ATG CA ear ( where we could take CA -BCC - Search Administration and configure the search projects) . Search Indexer Box --> The box with the ATG Search Index ear ( to fetch the index data from repository). Note that the engine performing indexing will need access ...

Mozilla FireFox - how to add security certificate exception urls

If you visit a web site with a secure connection(https) and if the website's security certificate has some problem like the security certificate presented by the website was not issued by a trusted certificate authority  or  the security certificate has expired or is not yet valid, you will get an error page ( like below in IE ) with an option to continue to this website. When this non secure page is loading, in Internet Explorer, you will get an option to specify whether you need to download the page content files like JS, CSS, Images,... But you will not get such an option in FireFox/Chrome and could see only the text data in this new non secure page. If you are doing some local development with FireFox/Chrome and have such a situation, you might want to override this security restriction. FireFox provides some exception url list in secure certificates menu. Go to Options - Advanced - Encryption - View Certificates and click the exception list and...

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 maxSpar...
