How to handle CHKP call in restart mode

Hi,
I am implementing checkpoint restart logic. The check point call is succesfull, when i am running in normal mode. But when i am runnning the program in restart mode by providing CHKPID in the BMP JCL parm field the XRST call is succesfully reading the check point ID and save areas from the log, i am also doing checkpoints in restart mode but the CHKP call is giving me return code AD. How can i handle if the job abends in restart mode.

Hi Krishna,

Programmer Response: Be sure that the specified function is valid for the
PCB specified by the request.

Did you used DB PCB for checkpoint call and you are running in which mode.

Thanks,
Abin

hi,
i am running as BMP and the PCB is I/O PCB. In normal run without specifing check point id in the JCl the CHKP call is succesful but the same call in resart mode is returing status code AD. Can'nt we do CHKP call when CHKPID is not blank in the JCL.

Hi,

We can do a CHKP call by specifying CHKPID in the JCL. I prseume CHKPID is a sympolic parameter.

Please make sure while restarting checkpoint call is amde after restart call.

Regards,
Abin
