Internally Scheduled Global Variable Backups

To use option 1, wherein backups are internally scheduled by the global variable checkpoint task, the following CA OPS/MVS parameters must be set:

GLOBALBACKUPINTVAL

This parameter specifies the time interval between backups in minutes.

GLOBALBACKUPPROC

This parameter specifies the name of the backup JCL procedure in a valid started task PROCLIB.

GLOBALBACKUPDSN

This parameter specifies the base GDG name of the backup data set.

GLOBALBACKUPMDSCB

This parameter specifies the name of the GDG model/pattern DSCB. In an SMS environment, it may not be necessary to set this parameter.

GLOBALBACKUPSTCLASS

This parameter specifies the SMS storage class that will be used to control the allocation of global variable backup data sets.

Note: When this parameter is set to a non-blank value, the GLOBALBACKUPUNIT and GLOBALBACKUPVOLSER parameters are ignored.

GLOBALBACKUPUNIT

This parameter specifies the generic or esoteric device name for the backup data set (for example, 3390, SYSDA, and so on). The GLOBALBACKUPUNIT can either be used on its own to direct the backup data set to any volume in the generic or esoteric group, or it may also be used in conjunction with the GLOBALBACKUPVOLSER parameter to direct the allocation to a specific volume.

GLOBALBACKUPVOLSER

This parameter specifies the volume serial (VOLSER) associated with the allocation of a backup data set. When this parameter is specified, the GLOBALBACKUPUNIT parameter must also be specified (for example, GLOBALBACKUPUNIT is set to SYSBK). GLOBALBACKUPVOLSER may be used to direct the backup data set to a specific volume in the SYSBK group (for example, WORK01).
