When to apply ETCC Patches

lastmanse Apr 25, 2019 12:00 PM

We are in the process of upgrading the EBS at a client from 11.5.10.5 to 12.2.7 We’ve run three iterations of the upgrade and keep coming down to an elapsed time of 5 days. We only have a 4-day window. The DBA proposed installing the ETCC patches the weekend prior to “upgrade weekend” in order to shave off a significant block of time. I am no DBA (what he does is black magic to me) - so I have no idea if what he is proposing is reasonable and reliable.

If we apply the ETCC patches well beforehand, we are changing the sequence of patching that we have religiously followed – which makes me nervous.

I am attempting to “vet” the change to make sure there is no risk associated with applying the ETCC patches well in advance of the actual upgrade.

Looking for advice and comments…

The installation of the 12.2.0 upgrade filesystem on a 64-bit Linux server should be done before the upgrade window. Immediately after the installation of 12.2.0 is completed, all middle tier ETCC patches should be applied to the newly installed 12.2.0 Oracle Homes. The DB ETCC patches require an outage to complete, and should be done during the outage window as there are many 12.2 DB patches required that are not required for 11i. Are you also doing a DB upgrade during this window?

If you patch bsu for WebLogic patching, the DBA should be able to apply all middle Tier ETCC patches in less than an hour, maybe even 30 minutes.

bsu patching is slow

Hi

You can refer to get inputs to minimize the upgrade downtime.

Best Practices for Minimizing Oracle E-Business Suite Release 12.2.n Upgrade Downtime (Doc ID 1581549.1)

Hope this helps!

Thanks
