In the 12c databases, ORA-39014 ORA-39029 ORA-31671 and ORA-00600 errors can be received during expdp or impdp operation.
In such a case, existing processes are terminated and errors similar to the following will appear in the alert log file.
“DW00 terminating with fatal err=600”
The possible errors in export and import are as follows.
1 2 3 4 | ORA-39014: One or more workers have prematurely exited. ORA-39029: worker 1 with process name "DW00" prematurely terminated ORA-31671: Worker process DW00 had an unhandled exception. ORA-00600: internal error code, arguments: [17183], [0x7FAD49A1E198], [], [], [], [], [], [], [], [], [], [] |
To solve the problem, the value of the open_cursors parameter should be increased and the value of the parameter “_optimizer_cost_based_transformation” should be set to off.
1 2 3 4 5 6 7 | SQL> alter system set open_cursors=1024 scope=both sid='*'; System altered. SQL> alter system set "_optimizer_cost_based_transformation"=off scope=both sid='*'; System altered. |
After the parameter change, the operations will be completed successfully.
Thanks a lot ……. it greatly helps me.
I faced this while migration from 11.2.0.4 to 12.1.0.2 PDB database , while at the time of importing into 12.1.
You are welcome.
