I am doing DB and EHP upgrade in my company.
There are two instances, CI with DB running on one system and DI alone in another system.
During the time of upgrade, How to handle both instances?
How to do the DB upgrade in this scenario? CI and DI
How to do the Kernel upgrade in this scenario? CI and DI
How to do the Application (EHPI) upgrade in this scenario? CI and DI
Can any one clear my doubts.
