Specify the NEWCKPTn data set through the $T CKPTDEF command

These data sets are only defined to JES2 at some time after initialization; they are not allocated until they are put into use during the checkpoint reconfiguration dialog.

If you have not specified a value for a NEWCKPTn parameter in the initialization data set, a $D CKPTDEF,NEWCKPT1 operator command displays the following:

$HASP829 CKPTDEF  NEWCKPT1=(DSNAME=,VOLSER=)

To remove a NEWCKPTn value without specifying an alternative value, specify:

$T CKPTDEF,NEWCKPT1=(DSNAME=,VOLSER=) | (STRNAME=)

To specify DASD values for NEWCKPTn:

    $T CKPTDEF,NEWCKPT1=(DSN=dsname,VOL=volser),
               NEWCKPT2=(DSN=dsname,VOL=volser)

To specify Coupling facility values for NEWCKPTn:

    $T CKPTDEF,NEWCKPT1=(STRNAME=strname),
               NEWCKPT2=(STRNAME=strname)
