Deleting the JES2 checkpoint structure

Use the JES2 reconfiguration dialog to move the checkpoint data set to another CF or to DASD.To use the dialog, ensure that you have defined a NEWCKPTx in the JES2 CKPTDEF initialization statement in one of the following ways:
- JES2 initialization parameters
- Dynamically through the $T CKPTDEF command
Issue the following JES2 command to switch to the alternate checkpoint data set:
```
$T CKPTDEF,RECONFIG=YES  
```
Follow the reconfiguration dialog prompts.
When finished, issue the following JES2 display command to verify that the structure is not still in use by JES2:
```
$D CKPTDEF
```
Deletion of the structure might need to be forced. See Deleting structures with SETXCF FORCE for more information on forcing deletion of persistent structures with the system command:
```
SETXCF FORCE,STRUCTURE,STRNAME=strname
```
If necessary, change the JES2 initialization parameters to point to the new checkpoint data set for the next JES2 warm start.

To re-initiate use of the JES2 checkpoint structure, issue the JES2 command:

$T CKPTDEF,RECONFIG=YES

Follow the reconfiguration dialog prompts.
