Once you will restart the database, wallet will be automatically opened. When a table contains encrypted columns, TDE uses a single TDE table key regardless of the number of encrypted columns. Once TDE is configured on the data, only the authorized users can access this data. We should copy the entire wallet to node 2 for enabling to use TDE. Internally, the Oracle database takes care of synchronizing the keystore context on each Oracle RAC node, so that the effect of the keystore operation is visible to all of the other Oracle RAC instances in the cluster. -rw-r. perfect doc for TDE enable on RAC PDB/CDB database, Your email address will not be published.
