Re: Rollback Sizing

The application (purchased) inserts one row at a time with only a final
commit. I cannot fix the application.

I am told that no one else was on the system (un-verifiable).

So, even if none of the rollback was released by commit, how did it get to be 3GB in size?

Can anyone shead any light?
