DALKYL2 specifies the label for the key encrypting key used by
the key manager. The key encrypting key is used to encrypt the data
(encryption) key.
When you code DALKYL2, # must be one, LEN must be 1 to 64, and
PARM contains the key label in EBCDIC. You must also include the DALKYC2
text unit.
Code the DALKYL2 text unit to do either of the following tasks:
- Specify the label for the key encrypting key used by the encryption
key manager.
- Override the label for the key encrypting key defined in the data
class of the data set.
Specification of the key labels does not by itself enable encryption.
Encryption must be enabled by a data class that specifies an encryption
format, for example EEFMT2. For complete documentation on using tape
encryption, see
z/OS DFSMS Software Support for IBM System Storage TS1140, TS1130, and TS1120 Tape Drives (3592).
Example: To specify a key label 2 of "LABELQ1.LABELQ2.LABELQ3",
code:
KEY # LEN PARM
