I'm using a perl-script, which cron starts every 10 minutes. First the script copies the archived_log_files to a secondary disk drive, checking wether the size is equal. Then both of them are gzip-ed and the gzip-ed files are compared and errors are evaluated. Finaly gzip-ed files older than a limit (in days) are deleted on both directories (drives).

All in all this is very stable, if you do not have jobs, producing lot of redo information. It happend that a job produced redo faster than the perl-script can pack old redo information. In the past it happened that more than ones 'instance' of the script were running due to too any redo information within 10 minutes. my current version exits immediatly, if a process whith the same name is running.
