Description

This statement specifies the data set name, and optionally the volume serial number, of a CA Spool checkpoint data set. Up to 2 CHKPTDS statements, numbered by the NUM parameter from 1 to 2, can be specified.

Note: If VOL is not specified, the system catalog locates the data set name.

CHKPTDS Parameters

NUM=n,

This parameter specifies the SPOOLDS data set number as a value from 1 to 2, which must be unique

DSNAME=cccccccc,

This parameter specifies a 1 to 44-character name to be used as the checkpoint data set name.

VOL=cccccc,

This optional parameter specifies the volume serial number of the CA Spool checkpoint data set.

If VOL is not specified, the system catalog is used to locate the CHKPTDS data set name. If this value is not found in the catalog, the system defaults to VOL=SPOOL0.

STRNAME=cccccccccc,

This optional parameter specifies the Coupling Facility Structure name to be used for MAS/EMAS communication using the Coupling Facility.

If this value is not specified or if it is a non-MAS system, the Coupling Facility is not used.

This parameter does not have a default value.

Note: For more information about defining the CA Spool structure within the Coupling Facility, see the Coupling Facility section under the topic Multi-Access Spool (MAS).
