Process for clearing down archivelogs via Rman

Process for clearing down archivelogs via Rman

The only way archive logs should be deleted is through rman, as follows.

Ensure that a backup isn't running at present

ps -ef grep bko - (or 'grep rman')

rman target / catalog or /var/opt/oracle/oratab_options)>

crosscheck archivelog all;

delete archivelog all backed up 2 times to sbt;

If this does not clear enough space, the 2 can be reduced to 1.

If more space needs to be reclaimed, then tha following can be used.

delete archivelog until time 'sysdate - 3';

Again the 3 can be reduced to clear more space. Note that using this method is a last resort, as it

deletes archive logs which have not been backed up to tape.
