expdp ORA-31633 while running the export script...

when ever we come across the "expdp ORA-31633" error... this means we need to remove the outstanding jobs that are already in there or using that table....

"ORA-00955: name is already used by an existing object"

we need to find the tables that are already been there and are not dropped once the expdp/impdp jobs are performed.(usually these are gone if the jobs exits normally without any errors/interruptions..)

select owner_name, job_name, operation, job_mode,state, attached_sessions from   dba_datapump_job  where  job_name not like 'BIN$%  order  by 1, 2;

If you see the tables... drop them.... and then try the expdp job again. This time it should work...

Hope this helps...
