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 allots too many threads to the report generation.

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