Hi,
I am looking into installing a patchset with minimum downtime. Standard
Oracle procedure for installing a patchset is:
1. Shutdown the database
2. Install the patch binaries, relink.
3. Startup database (restrict ?), run the cat* scripts.
I wanted to change the procedure so that instead of having the database down
during the patch install and relinking, prior to the procedure I copy the
binaries to a newly created home, install the patch on the new home, relink
the binaries under the new home, and than just restart the database from the
new home. To make sure that everything is OK, I would postpone the cat*
scripts run, for a later time, once I am sure that everything is OK. If
something goes wrong I haven't changed anything in the database, and I can
just go back to the old home.
Has anybody tried this ? What is the significance of cat* scripts. As far
as I understand them, oracle does not use them and do not care about them,
only some apps might break (most of all DBA type of scripts).
Thanks.
Djordje
