Large BI Publisher Reports Fail with Error "java.lang.OutOfMemoryError: Java heap space" As Maximum Threads Constraint Work Manager Is Not Defined On Oracle WebLogic Server (Doc ID 2157260.1)

While processing large BI Publisher reports, the Oracle WebLogic Server can use multiple concurrent threads to generate the report.

If the threads are not constrained, out of memory errors can occur when the Oracle WebLogic Server creates too many threads assigned to report generation.

To address this situation users can now create a 'Work Manager' in the Oracle WebLogic Server, to limit the number of threads that are assigned to BI Publisher report processing.
