TDE : master key wallet : wallet file lifetime while open / password update / performance if wallet
Hello,
There is a list of items I seem not finding any answer to:
- Suppose, the master key wallet is the wallet that contains on the master key (MK) for TDE. So,
#1 When Oracle instance opens MK wallet, what happens next:
1.1 Does Oracle load MK in memory and never reads MK wallet file again during the life of instance? Or,
1.2 Does Oracle perform numerous I/Os on that MK wallet file.
#2 If MK wallet is shared,say, between two Oracle database instances - A and B,
2.1 If instance A open wallet and than instance B changes the wallet password, how is instance A functionality affected?
