Cloning Question

    I spent a long time trying to clone our production data warehouse into test, to refresh it. I do this frequently, as both a way to refresh test instances and to test the backups. After fighting through 2 bad backups, I finally got a good one. However, the problem I had was that the production rollback tablespace is larger than the disk on test.

    My thought was that I could restore everything except the rollback tablespace, which is not the way I usually do it. I commented out the rollback_segments line in the init.ora and created a script that would create a new rollback tablespace and rollback segments, smaller than those in production. This didn't work, even though Oracle support said it should have. When I did the clone, the database would not open. I kept getting the following error:

ORA-00600: internal error code, arguments: [25012], [1], [2], [], [], [], [], []

Does anyone know what I was doing wrong? I can't figure it out, and Oracle support couldn't figure it out, either. I was able to get the database up by getting more disk added, so that there was enough space to restore the rollback tablespace file.

Thank you.
