KEYLABEL keyword

The KEYLABEL keyword specifies the key label used for data set encryption.

KEYLABEL='key_label' specifies that the base cluster is to be encrypted. Any alternate index associated with the base cluster will also be encrypted and use the same key label as specified for the cluster.

For more information about data set encryption support, see Data set encryption support.

key_label
Specifies the name, up to 64 bytes, of the key label to be used to encrypt image copy data sets. The parameter must be enclosed in single quotation marks (').

If a key label is defined as a DATACLAS attribute used for the allocation of the data sets, the key label you specify for the KEYLABEL keyword overrides the key label defined for DATACLAS.

See the topic "Understanding the Order of Assigned Data Set Attributes" in z/OS DFSMS Access Method Services Commands to learn more about the order of precedence (filtering) the system uses to select the key label.

Default value
None.
Usage note
The KEYLABEL keyword cannot be used with the COPY process of Advanced Image Copy Services. The original key labels that are used for the input database data sets are inherited.
