I am attempting to run an analyze job that estimates statistics based on 5% of the data. I have a table with 5% equalling 3.9 million rows. My job continues to fail complaining about the rollback segment being to small. I feel that I have a significant amount of rollback space and am wondering what the best way to troubleshoot this problem is.

Thank you.

Create rollback segment with higher value. Use this
big rollback segment before starting transaction.
Before executing sql statment execute following statement
ALTER TRANSACTION USE ROLLBACK SEGMENT NEW_ROLLBACK_SEG

Replace NEW_ROLLBACK_SEG with new rollback segment name

This will solve your problem.
