OWB Control Center Service Hangs During Parallel Execution of SQL Loader Mappings (Doc ID 1402193.1)

Last updated on MAY 09, 2017

Applies to:

Oracle Warehouse Builder - Version 10.2 and later
Information in this document applies to any platform.

Symptoms

During the execution of Process Flows running SQL loader mappings in parallel, the Control Center Service stops to process mappings. Inspecting the runtime log file shows that for some SQL loader mappings the following lines are missing:

Report_execution_result auditId=xxxx
AuditId=xxxxxxxx: Request completed


Also can be seen that some SQL loader log files are not complete. They look truncated and are missing the load summary at the end of the log file.

The issue has been observer on AIX, on which it caused a heapdump with extension phd (IBM Portable Heap Dump). But the issue might occur on other platforms too.
