 We are in process of upgrade from oracle application release 12.0.4 to 12.1.1 and we are in the first phase of upgrading the database from 10.2.0.2.0 to 10.2.0.4.0
After upgrading the database to 10.2.0.4.0 NUMA is enabled by default, below is the extract from the alert log

-------

where NUMA PG = 1, CPUs = 4

-------

and

How will we check the production performance during NUMA enabled? it is enabled by default.

If we upgrade the production instance and then any issues arises in prod, will oracle support

Howdy, Stranger!
