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.


  1. Java Thread Dump Analyzer,fastThread ,a universal tool that will parse and analyze thread dumps written in any language that runs on the JVM. It will convert your Java, Scala, Jython, JRuby thread dumps to useful information for root cause analysis (RCA).

ATG CA - BCC home screen : how to add a new link

          Activity source is the property which controls the links on the left nav on the BCC home screen. All activity sources are registered with the ActivityManager component at /atg/bizui/activity/ActivityManager . When rendering the BCC home page, the ActivityManager cycles through all the registered ActivitySource components and displays left navigation links for each of them on the BCC home page. For example if I want to add a new link "My New Link" , below screen shots exaplins how this can be done 1. Add to specify the activityresources. In this  activityManager, I specified one MyActivitySource. 2. Add  to specify the name of the link and the other details . Here it refers to a bundle properties file.  3.

ATG Search Indexing - behind the scene steps explained

Read more about the search indexing @ 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 :                     66900009 @ index engine box        66900010 @ search engine box        c. Lets assume that the component SearchEngineService has the "

ATG Search and startRemoteLauncher

If the search engine application is running in a separate box than the ATG CA-BCC deployed server, the search engine is invoked through a remoteLauncher running in these boxes. Means, a remoteLauncher needs to run in the host where SearchEngine is installed remotely to start the search engine. You could find the @ ATG/ATG2007.1/Search2007.1/SearchAdmin/bin/ Start remoteLauncher using the command   ./ –p <RMI Launcher service Port > & The Launcher Service Port on the host machine can be found in BCC @ Search Administration>Projects > Search Project: gmri_search_en_CA > Environments > Host Machine: > Advanced Settings. If the startRemoteLanucher reports a BindingException , then you need to find the process that is using the launchServicePort. For that run the netstat command like :   netstat -an |grep 10880 Then inorder to identify the process that uses this port run the command like : r

Search Facets - how to create a new search facets in ATG Search

A Facet is a search refinement element that corresponds to a property of a commerce item type. ATG supports the search result refinement using the Faceted Search concept. Read more about facted search @ . Facet can either be ranges or specific values. Each facet is stored in the RefinementRepository as a separate refineElement repository item. Facets are divided into Global and Local facets. Global facets apply to all the categories and local facets only to the category in which they are created. For example Price/Brand can be considered as the facets that are common for all skus and New Release/Coming Soon can be considered as the facets that are specific to Physical Media products like Vidoe/DVD/Blue-ray/Books. We can use the ATG BCC - Merchandising UI to create facets. The Faceting Property depends on the meta-properties defined in the \atg\commerce\search\product-catalog-output-config.xml ( the definitionFile of the \atg\commerce\s
