RE: Cloning Question

Scott - I think that Rachel offered better advice, and I'm sure you've read her note by now. I have some experience with missing files when cloning a database :-), but I haven't had the rollback tablespace missing, and that would be different. One thought would be to create an extra rollback tablespace on production, so that when you perform the clone operation, Oracle still has some rollback segments available. Dennis Williams

Dennis,

    No. I did a create controlfile set database... I commented out the rollback_segments line in the init.ora and removed the reference to the file in
the create controlfile statement. With no reference (that I know of) to the rollback segments or tablespace, I thought that the database should have come
up, then I could create a new one. I must have missed something, but I don't
know what that was.
