It looks promissing, if you are going for 10 archive logs, I would think it is too much of a kill. But again it depends on your archive log size. If it were to be a 5MB archive then 10 is too much of an over kill. On the other hand if it were to be 256M then I'ld think its o.k. But would make to wonder why one would set the logsize to be of 256MB

Good luck.
