Introduction:

If the number of entries approaches the capacity of the checkpoint, use the RMODBASE utility MAKECKPT control statement to expand the size of the checkpoint or copy the checkpoint to a new data set.

MAKECKPT will make a new checkpoint, copy the old checkpoint data to the new checkpoint, and delete the old checkpoint.   

In the MAKECKPT control card, if you specify EMPTY, a new, empty checkpoint is created.

If EMPTY is not specified, data from the old, existing checkpoint is copied to the new checkpoint.

Starting with Deliver 12.2, the checkpoint file can have a maximum size of 200 cylinders.

The below steps detail how to expand the checkpoint file.

 

Environment:
CA Deliver - All Releases
Instructions:

 . Using "/F rmostc,OFF", shut down any Deliver RMOSTC tasks that use the checkpoint file in question.

 . The checkpoint file is expanded for existing database DELIVER.SYSTEM1, in this example:

//EXAMPLE4 JOB ACCOUNT,PROGRAMMER 

//STEP1 EXEC PGM=RMODBASE 

//STEPLIB DD DSN=CAI.CVDELOAD,DISP=SHR 

//SYSPRINT DD SYSOUT=* 

//SYSIN DD * 

NAME DELIVER.SYSTEM1 

MAKECKPT UNIT=3390 VOLSER=RMO004 CYLINDER=40

/*

//

 . Note: In the above, the original checkpoint file is less than 40 cylinders, and is being increased to 40 cylinders.

 . Restart the RMOSTC tasks.
