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.

Re: Cloning Question
I thought there was a rollback segment in system that would be there. It should be enough to get things started. After all, there isn't a separate one when you create a database, until you create it.

Re: Cloning Question
In some versions of Oracle, you need a SECOND rollback segment created in the SYSTEM tablespace in order to create another tablespace. It can't hurt to add it (you can drop it immediately after you get the rollback tablespace created) but it could be the solution. Since you didn't include the version of the database you are working with, we have to be somewhat generic in our answers Rachel |+--- || | || | || srcdco@ritvax| || .rit.edu | || | || 05/09/2002 | || 02:28 PM | || Please | || respond to | || ORACLE-L | || | |+--- | || | To: [EMAIL PROTECTED] | | cc: (bcc: Rachel Carmichael) | | Subject: Re: Cloning Question| | I thought there was a rollback segment in system that would be there.
