I wanted to do online redefinition on a table. Whenever I run start_redef_table procedure then, while creating materialized view it failed with ORA-03114 and ORA-03113.
Below is the scenario.
SQL> exec dbms_redefinition.start_redef_table('M', 'HISTORY', 'HISTORY_INT');
ERROR:
ORA-03114: not connected to ORACLE
BEGIN dbms_redefinition.start_redef_table('M', 'HISTORY', 'HISTORY_INT'); END;
*
ERROR at line 1:
ORA-03113: end-of-file on communication channel
In the Alert log file it displays,
Sat Dec 6 16:34:40 2008
Errors in file /var/opt/dumpfile/udump/arjudb_ora_12860.trc:
ORA-07445: exception encountered: core dump [kghalp()+58] [SIGSEGV] [Address not mapped to object] [0x000000068] [] []
ORA-10980: prevent sharing of parsed query during Materialized View query generation

Cause of the Problem
This is an oracle bug. When auditing is enabled and creating materialized view or executing start_redef_table and a Commit/Rollback/Abort transaction is done, memory which is being cleaned up is accessed leading to a dump.
Solution of the Problem
As this problem is an oracle bug and this bug fires when auditing is enabled so there are two solutions.
1)Disable Audit and Restart database:
SQL> alter system set audit_trail=NONE scope=spfile;
System altered.
Since audit_trail is a static parameter so it is needed to bounce the database.
SQL> shutdown immediate;
SQL> startup
2)Apply Patch 10.2.0.3:
This bug is fixed on 10.2.0.3. So apply patch set 10.2.0.3.
