Has a TDE Keystore previously existed in a database
Oracle 19c 19.13.0.0.0
Windows 2019
How can I see if TDE was ever configured in a database? I don't mean checking the parameter 'TDE_CONFIGURATION' or 'WALLET_ROOT'. Assume Oracle was restarted with those parameters cleared out.
Is any key information stored in a tablespace or something? Is there a query that should show that at some point a wallet was configured?
This is all in an examination of a DEV environment where I suspect tests of wallets were done but am not sure. This is necessary to know since you can't successfully recreate a wallet in an environment that already had one that is no longer present.
