Maybe I missed something. Reading about Oracle transparent data encryption (TDE), some references say about rekey (or rotate) the master key. But why should we do that?
I mean, why to execute the following command?
ADMINISTER KEY MANAGEMENT SET KEY IDENTIFIED BY teste123;
I am sure this don't mean change wallet (keystore) password, since for that we need to execute:
ADMINISTER KEY MANAGEMENT ALTER KEYSTORE PASSWORD FORCE KEYSTORE IDENTIFIED BY "teste123" SET "123teste" WITH BACKUP USING 'OLDKEY';
