RE: Cloning Problems

Ethan,

Consider performing the clone in 2 distinct phases (my SOP). 1) Copying the source database to the target machine w/ recovery if necessary, and 2) Renaming/recreating the controlfile.

The recovery can be against a hot backup copy or cold w/ a controlfile backup, and assures one of having a viable database for renaming. This method also gives you the option to apply post-copy archived redos from the source database if last minute changes are required on the clone.

Please let me know if I've missed your point, as my short-term memory is not what it should be.
What was I saying? ;>

Michael,

See previous post. It does appear that even during a shutdown immediate (which does checkpoint) that instance recovery could be required. Thus we need redo logs. Yes they will be recreated as you stated. However, there is no way to both rename the database and perform instance recovery on a clone from a cold backup. Thus the solution is going to be either shutdown normal or perform a few log switches and shutdown right away (and cross fingers). These both should work but a straight shutdown immediate seems to be risky.

>From my understanding you do not need the on-line redo logs unless you
perform a shutdown abort. As a matter of fact the database will create the logs if they do not exist when you issue the "alter database open resetlogs" command.
