Yesterday my project architect requested me to apply patches in some testing environments.
As Part of prerequisites i queried ad_applied_patches. I found that all the patches are apllied to the testing environments.
I know about cloning. If we clone some environments, then all the patches was applied in that environment will be available in target environment.
But my architect saying that only EBS databases are refreshed from production, no application tier cloned. So we have to apply patches in all testing environment.
I am not getting what he is saying.
we can refresh EBS database but
Is that one will work with existing application tier?
Is we have to apply patches in the testing environment?
Could someone please clarify my doubts.
If you are doing a database refresh from production, then you will need to apply the patches again in the test environment if the patches are not applied on the production.
Yes, the db only refresh will work with the existing application tier.
