Folks On a 2 Node RAC 10gR2 Database, expdp is NOT working. $ expdp system/<passwd> Export: Release 10.2.0.2.0 - 64bit Production on Thursday, 25 January, 2007 21:41:41 Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - 64bit Production With the Partitioning, Real Application Clusters, OLAP and Data Mining options UDE-00008: operation generated ORACLE error 31623 ORA-31623: a job is not attached to this session via the specified handle ORA-06512: at "SYS.DBMS_DATAPUMP", line 2745 ORA-06512: at "SYS.DBMS_DATAPUMP", line 3712 ORA-06512: at line 1 As per metalink Doc ID: 308388.1:- Cause For submitting an export job with datapump utility, we use queues, streams and java objects. SQL tracing confirms that. If we see any component is not valid in the database, we will see these errors. By querying dba_registry we find the different component and their status. Solution SQL> startup migrate SQL> @?/rdbms/admin/catpatch.sql SQL> @?/rdbms/admin/utlrp.sql SQL> SELECT comp_name, version, status FROM dba_registry; ACTION ?/rdbms/admin/utlrp.sql has been Run, whereafter following SELECT command still shows 10 Objects belonging to PUBLIC & SYS as INVALID & the ORA-31623 Error continues to occur. Qs - Since $ORACLE_HOME/rdbms/admin/catpatch.sql is NOT present, can catalog.sql , catproc.sql be safely RE-Run in a Working 2 instance RAC Database from 1 of the RAC instances?
