Re: Cloning Question

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.
