Home -> Community -> Mailing Lists -> Oracle-L -> Re: RMAN Quick clean-up
Hi. We discovered this too. If you are running on
the Unix platform you can try playing with the script
below. I don't guarantee it to be bug free since it
is hot off the press but it works for me.
Incidentally this just generates a script which you
need to run. I'm not overly confident about
automating deletes of backups at this point, so I
would rather be able to check successful tape backups
before running the delete. (Call me paranoid) :) We
are running Oracle 8.1.6 on Solaris 2.6 so this script
is based on that assumption.
