In addition to using the DELETE INPUT clause to delete archivelogs
immediately after backing them up successfully once, remember that you can
also arrange to delete archivelogs after they have been backed up "N" times.
I schedule an hourly job to run the following command using 9i RMAN:
RMAN> delete archivelog all backed up N times to device type X;
where "N" is an integer and "X" is the string "disk" or "sbt" (tape).
Obviously, deleting the archived redo log files immediately after backing
them up once makes the best use of disk space in the archive log
destination(s). But it tends to make folks a bit squeamish, for good
reason. So, I use the DELETE command above in 9i RMAN to allow it to be
backed up at least 2-3 times before finally deleting them...
