ORA-46717
Cannot import keys to external keystore (OKV/KMS)
Cause
An attempt is being made to clone a pluggable database (PDB) to a multitenant container database (CDB) which is configured to use an external keystore (OKV/KMS) for Transparent Data Encryption (TDE), however the source database is using a file-based keystore.
Action
Either configure an external keystore (OKV/KMS) for the source database by using the 'MIGRATE' clause of the "ADMINISTER KEY MANAGEMENT" command, or on the CDB where the new PDB is being created, configure a file-based keystore by using the 'REVERSE MIGRATE' clause of the "ADMINISTER KEY MANAGEMENT" command.
