Dear Team,

We have a complex application which is deployed on Web Logic Server. We have export functionality with requirements of exporting the huge records
(50,000-1Lakh). We have server with capacity of 16GB. The application runs fine when only singer user export the huge data. But we are getting
OutofMemory Error when more than one user tries to export.

We are using JSF 2.0, Prime Faces,EJB and JPA

We tried increasing the heap size for Web Logic server, that could not help.
Is there any way where we can check the web logic server performance when these exports are running. We want to find if any memory leak exists.
Any other suggestions also welcome.

Thanks in Advance

You appear to have arrived on the wrong forum; this is for discussing the website itself. Let's try moving you somewhere more appropriate.

You can start by taking a heap dump when OOM and analyze by any suspect using Eclipse MAT


-XX:-HeapDumpOnOutOfMemoryError Dump heap to file when java.lang.OutOfMemoryError is thrown. Manageable. (Introduced in 1.4.2 update 12, 5.0 update 7.)
