When one runs dbms_stats how often is the data committed? Before Oracle exports a table it needs to gather information about it such as the columns comprising it. I wonder if this information also includes data changed by dbms_stats and/or RMAN.
We used to have similar problems when exporting while an application was doing quite a few drop tables and CTAS's. However that pretty much went away with 8.1.7.

A user level export received the snapshot too old error and terminated. Concurrent to this was an RMAN backup and DBMS_STATS.GATHER_TABLE_STATS(...) which was being run on the same schema being backed up via the user level export. There was no other end user access to the schema data. Since exp got the error I assume it was reading from the rollback segments but why? I'm suspecting dbms_stats. We have ample RBS. Is there any significant undo generated by dbms_stats or RMAN which could create this problem? (Of course we need to improve our job scheduling but that's another issue, the timing of the user level export is application driven and out of our control).
