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.
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.
