Can somebody please tell me how to encrypt an existing tablespace in 11g? The wallet has been setup and the sqlnet.ora points to it.
SQL> select STATUS FROM V$ENCRYPTION_WALLET;
STATUS
------------------
OPEN
I alter the tablespace offline ...
alter tablespace USERS offline normal;
But I can only find the 12n and above command for the next part:
ALTER TABLESPACE users ENCRYPTION OFFLINE ENCRYPT;
Many thanks in advance for the 11g command.
