Hi all -

8.1.7.2, Windows 2000 sp 2

I'm working on my backupexec implementation. For some odd reason the backup job that copies the arclogs to tape and deletes them off the disk (what BE calls an 'archive' job) wants to delete the directory too. Sometimes the directory is deleted, and sometimes it isn't.

So I whip together a perl script to fire after the backup to check for the arc directory and recreate it if it isn't there.

Well, I expected Oracle to crash if it couldn't find the arc directory. Instead it wrote to the directory where the arc directory used to reside with a different name.

Maybe it's platform specific, but doesn't this seem odd? I would rather have my db crash if the directory doesn't exist. My backups would be all hosed because the arclogs wouldn't end up being written to tape properly. In fact I'm betting that BE will err out when looking for that directory.

Here's what I see in v$archived_log. 693 and 694 are when the directory still existed. 695+ are after the directory got deleted. Anyone seen this before?

       693  480186148 D:\ORACLE\ORADATA\RMANTST\ARC\RMANTST_00428.ARC   
       694  480186151 D:\ORACLE\ORADATA\RMANTST\ARC\RMANTST_00429.ARC   
       695  480268708 D:\ORACLE\ORADATA\RMANTST\ARCRMANTST_00430.ARC    
       696  480268709 D:\ORACLE\ORADATA\RMANTST\ARCRMANTST_00431.ARC    
       697  480268711 D:\ORACLE\ORADATA\RMANTST\ARCRMANTST_00432.ARC    
       698  480268715 D:\ORACLE\ORADATA\RMANTST\ARCRMANTST_00433.ARC    
       699  480268718 D:\ORACLE\ORADATA\RMANTST\ARCRMANTST_00434.ARC
