Home -> Community -> Mailing Lists -> Oracle-L -> RE: Cloning Problems
Ethan,
Your first line of the trace file is the same as mine when I clone from cold
backups.
I also always do clean shutdown normal before cold backup but I think you
should be okay with shutdown immediate too (IMHO). I think if you are
renaming the cloned database then the RESETLOGS option is required.
You said the database was shut down IMMEDIATE and you had no control over this.
Did someone else shutdown and do the backup for you?
Don't forget to check the obvious.
Are you sure the backup was completely closed (not rolling back) before the
backup began? (You're used to hot files)
Are you sure the database was not restarted before the backup completed?
Are you sure you copied ALL files to your cloned database? (I copy
everything, then delete control files, then create controlfiles)
Take a quick check on the timestamps on the files you backed up. See if
there are any time differences that jump out at you.
Good luck,
Ed

Yeah, went through the standard cloning process. My first line of trace file looked like this...
CREATE CONTROLFILE SET DATABASE "DM8" RESETLOGS NOARCHIVELOG I am wondering if I should have stated NORESETLOGS here instead, that way the data in the redo logs would be available and then the cloned instance could have performed instance recovery. I have always used the method above and never had any problems but that is likely because I have always done a SHUTDOWN NORMAL instead of SHUTDOWN IMMEDIATE. While the SHUTDOWN immediate performs a checkpoint it looks like there can still be stuff out there in the logs that will require instance recovery. Since I did a RESETLOGS I am guessing this necessary info is missing. Wondering if everything will be OK if I try to find another way to get the clone opened, like setting the hidden allow corrupt logs parameter.

Did you recover the database using backup controlfile? Try that. HTH, Ruth
