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 Indexing - overview of different steps in search indexing

Read more about the search indexing behind the scene steps @  http://tips4ufromsony.blogspot.in/2011/12/atg-search-indexing-behind-scene-steps.html ATG Search prepares searchable content by indexing the products specified in the XML definition file (/atg/commerce/search/ProductCatalogOutputConfig). Generally there are two types of indexing 1.  Full Indexing  --> all data taken for indexing 2.  Incremental Indexing --> only changed data will be taken for indexing When full indexing is triggered, following happens:    1. The out of box component BulkLoader will call IndexedItemsGroup.getGroupMembers() to load the products to the XHTL document. It prevents uncategorized products from getting indexed. The definition file format begins with a top-level item as a product and includes the properties of parent category and childskus. For each product, the set of Variant Producers configured in ProductCatalogOutputConfig is execute...

ATG search and Monitoring the request and response

To get an idea of the SearchEngineActivity logs, please read the blog :  http://tips4ufromsony.blogspot.com/2012/01/atg-search-and-search-engine-activity.html Other than using the SearchEngineActivity logs, we could monitor the search engine request/reponse  by enabling the monitoring in the SearchEngineService component @ /dyn/admin/nucleus/atg/search/routing/SearchEngineService. Once you enable this "monitoringEnabled", each request/response and the response time like last response time and average response time can be found @ SearchEngineService component. After you send a request to the search engine, just refresh the SearchEngineService component and you could see that the total command count will be incremented by one and the response time also get updated. If you click this total command count, a new window will be opened with the request and response details.
