Query result to check if TDE was implemented prior or TDE was never implemented:

In 11g DB:

SELECT BITAND(FLAGS,8) FROM X$KCBDBK;

If this query returns 8, then TDE is/was implemented. (TDE REKEY/SET KEY is done for this database and the MKID of SYSTEM tablespace is the MKEYID of that previous/current wallet file)

If this query returns 0, then TDE is never implemented (TDE REKEY/SET KEY was never done for this database and the MKID of SYSTEM tablespace is the pre-generated ID)

In 12c DB:

select mkloc from x$kcbdbk;

If this query returns 1, then TDE is/was implemented. (TDE REKEY/SET KEY is done for this database and the MKID of SYSTEM tablespace is the MKEYID of that previous/current wallet file)

If this query returns 0, then TDE is never implemented.(TDE REKEY/SET KEY was never done for this database and the MKID of SYSTEM tablespace is the pre-generated ID)
