I'm not quite sure what you mean by "modify the database startup procedure." You must be in MOUNT mode to change between archive and noarchive. You don't need to change the mode each time you startup you database. Once you put a database in archivelog mode, you are in that mode until you change it - no matter how many startup/shutdowns you do. It doesn't matter if you have a cold vs. hot backup. As long as you have database backup and all of your archivelogs, you can do a point-in-time recovery from that backup until your last archivelog.
Jay >>> [EMAIL PROTECTED] 10/18/02 12:09PM >>> I'm up for my backup and recovery class here soon, but this conversation has brought up questions that I think some of you wouldn't mind discussing anyway. I see where implementing archive logs requires that you modify the database startup procedure to turn on archiving before opening the database. At this point the DBA should do an immediate "baseline" backup (orafaq =)) which implies a hot/online backup. I am curious how this goes with point in time cold backups. ie. DBA does a cold backup opens the database in archive log mode. Can you apply accumulated archive logs to a restore from cold backup ? perhaps there are issues with the control file information..... -----Original Message----- Sent: Friday, October 18, 2002 7:53 AM To: Multiple recipients of list ORACLE-L theoretically only the archive files after the backup started are needed. but there might be issues of a corrupted backup, and to guard against that we have a policy of keeping archive files for one week. you should also keep checking your backups by restoring them to a separate location periodically regards Naveen **DISCLAIMER This e-mail message and any files transmitted with it are intended for the use of the individual or entity to which they are addressed and may contain information that is privileged, proprietary and confidential.
