ORA-19699: cannot make copies with compression enabled
Cause: Datafile copies with compression are not supported
Action: If the function dbms_backup_restore.backuppieceCreate is called outside RMAN, then the incompatible values are being passed for the parameters docompress and imagcp. If this message occurs during an RMAN job, then this is an internal error in RMAN, and you should contact Oracle support
