BR0005I BRARCHIVE terminated with errors

Cause:

1. Archive destination has reached 100% & DBA has removed or zipped the archive files causing mismatch/unavailability of archive sequence for brarchive backup

2. /oracle/PRD/saparch/archPRD.log file is corrupted 

3.  /oracle/PRD/saparch/archPRD.log file has got unwanted characters due to improper editing 

Solution:

Step 1. create a backup copy of arch<SID>.log 

cp /oracle/PRD/saparch/archPRD.log /oracle/PRD/saparch/archPRD.log_bkp

Step 2. check the line number mentioned in the error , go to archPRD.log using vi :1830934 & take appropriate action. Possibly it may have blank line or unwanted characters.

BR0123E Format error found in line 1830934 of /oracle/PRD/saparch/archPRD.log at location arch_last_get-10

Try executing backup again , if still same error then go to step 3

Step 3. It seems archive sequence missing issue , append available archive sequence at below highlighted line at the end of the file to direct brarchive to start backup sequence post 33999. Make sure it is correctly formatted as per similar looking old lines

Try executing backup again , it will show messages like
"BR0017W Offline redo log file ' ' not found" which is ignorable & same has been skipped due their unavailability as directed by us. 

Backup should execute successfully now & will avoid error code 6  "backup failed to back up the requested files" in netbackup logs
