Issue/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.

Resolution

 . 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.
