Hi Erman,

Our environment:

2 node apps tier  R12.2.5(shared appltop)
2 node db 12.1.0.2(RAC)

We are about to implement GST(GO-LIVE) next week in PROD.
We have few concerns and requesting your suggestions

1)Take rman L0 backup just before starting the patching activity(patches may take 7 hours to get applied)
2)During the patches application,users will be connected and performing online transactions.

Once all the patches are applied:
Before cutover,can we bring down the application and database to take rman level0 backup(cold) again?
will this create any issues in completing the whole online patching cycle like cutover and cleanup?

If something went wrong,we are planning to restore L0 backup which is taken just before cutover.Because this will have user transactions as well

Thanks,
Raj
