So I hear but I am not sure this is what he did.  I have sent and asked
this question of him but have not received answer back as of yet.  I did
tell him that backups will not complete until this is resolved

You can't just delete archive logs, you have to use RMAN to remove them.

Per one of my oracle DBAs.

Go into RMAN, Connect to Catalog
Run "change archivelog all validate;" then "resynch catalog;"
Run full backup.

I'm not an Oracle DBA but I know if you've manually deleted Oracle
Archive logs that's not a good thing.

I just got off the phone with my NetBackup support.

Excuse me for my lack of knowledge here.  Not an Oracle/Linux guy at
all.

That being said, here is scenario of what happened nearest I can tell.

Oracle backups have been failing.

What ever function tells Oracle that it is ok to clean up transaction
logs has not been saying it is ok.

Log disk filled up

Oracle/dba guy deleted files to make room

Job fails with new error stating the log file it is supposed to backup
does not exist.

My NBSupport says he deleted the logs from the file system and not from
Oracle so when agent queries Oracle,  it says backup this file but when
it goes to do it,  file does not exist.

Make any sense at all ?

Dave

The oracle client does nothing like that, all the management of archive
and redo logs is always handled within Oracle.  The agent simply
understands both RMAN and Oracle API and executes a RMAN script.  Keep
in mind that at times some house cleaning is needed between the RMAN
catalogs and the NetBackup catalogs in reference to expired images to
RMAN backup id names.

Thanks
