Message-ID: MIME-Version: 1.0 Content-Type: text/plain Title: RE: Oracle Recovery from Cold backup. No.  The control file has the current state of the database.  It will consider the database up to date if all the scn's match.  You could fool the database into rolling forward with a more recent copy of the control file (say at the time of crash), but if you are recovering with an old version of the control file (at the time of the day-old backup) you can't make Oracle apply archive logs that are newer, and have newer SCN's, to the database.   did I explain that clearly? Ron, try it sometime.  Recovering with a more recent control file is kinda slick :) Lisa Koivu Oracle Database Administrator Fairfield Resorts, Inc. 954-935-4117 -----Original Message----- From:   Smith, Ron L.

I know, but the point is Oracle doesn't know anything about the archive logs, it just takes whatever you feed it until you cancel. Correct?   Ron -----Original Message----- Sent: Friday, September 21, 2001 1:12 PM To: Multiple recipients of list ORACLE-L As long as you have all archived log files in log archive destination directory, which is defined in init.ora, you don't have to do anything but type 'auto' while doing recovery. Oracle will automatically apply all necessary archive log files and then you need to open database.   "Smith, Ron L." wrote: I have a "what if" question. Say you had a complete cold backup, including control files from a few days ago. You also had all the archive logs for the past few days. Today you lost your server and had to recover. You lay down all the database files, including the control files. Now you want to apply your archive logs. Oracle can't know about the archive logs because all the files you restored are old. Do you just tell Oracle where the archive logs are and it keeps aplying them until you say you are finished? Just wondering.
