I have the only process running on the server. I am using an undo tablespace with 15 GBs of undo. I have undo retention set to 20000(I just upped it due to the error) and I get the following error. There is a little blurb on metalink about increasing undo retention. I got rid of degree but still got an error on the parallel slave. The Rollback segment that gives me an error changes every time. Any idea?

I get the error on PQ slave even when I remove Degree.

SQL> exec dbms_stats.gather_schema_stats(ownname=>'MY_SCHEMA',options=>'GATHER AUTO'); BEGIN dbms_stats.gather_schema_stats(ownname=>'MY_SCHEMA',options=>'GATHER AUTO'); END;
