Title: Archive files and their Management

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----- From: Naveen Nahata [mailto:[EMAIL PROTECTED]] Sent: Friday, October 18, 2002 7:53 AM To: Multiple recipients of list ORACLE-L Subject: RE: Archive files and their Management 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 -----Original Message----- From: Yechiel Adar [mailto:[EMAIL PROTECTED]] Sent: Friday, October 18, 2002 4:49 PM To: Multiple recipients of list ORACLE-L Subject: Re: Archive files and their Management Our policy is to keep archive for the last 2 days at least. We are doing daily backup so it gives us the option to restore from the last backup or the one before without restoring archive logs.   Yechiel Adar Mehish ----- Original Message ----- From: Denham Eva To: Multiple recipients of list ORACLE-L Sent: Friday, October 18, 2002 12:28 PM Subject: Archive files and their Management Greetings Gurus Just wondering....... Our archive log's directory has grown substantially and space is becoming an issue. How do you know which archive files is safe to delete? In other words... Do you delete all archive files older than the last backup? Should you keep all archive files until it is obviously pointless? Please advise.
