Re: Patchset installation

Djordje,
I have seen a new code tree installed on the same box for testing purposes. I don't know the impact of not running the cat* scripts but would not try that myself. This weekend I installed the 8162 patchset on several boxes and the catalog, catproc, catrep, and java system took a long time to run on each db. I was definitely looking to speed up the process and would appreciate a tip or two. But the patch install itself only took ten minutes. Don't see that this approach would have saved me much downtime. Cheers,
Dan
