Data Pump Export hangs while unloading the system procedural objects, e.g :
under the following circumstances:
- OLAP and Workspace Manager components are installed
- SQL trace (10046 event) shows 'wait for unread message on broadcast channel' in the datapump master trace file (DM).
- Querying active sessions and review of AWR taken during export shows a spin for:
BEGIN :1 :="SYS"."DBMS_AW_EXP"."SCHEMA_INFO_EXP"(:2,:3,:4,:5,:6); END;
- Applying Patch 14192178 or Patch 11840083 do not solve this issue
- Gather system and dictionary statistics using DBMS_STATS.GATHER_SYSTEM_STATS and DBMS_STATS.GATHER_DICTIONARY_STATS do not solve this issue.
o While running SQL BEGIN "SYS"."DBMS_CUBE_EXP".SCHEMA_CALLOUT which causes export to hang on estimate
