Pls help me how to restart the IMS DB program by using XRST call in IMS. What are the parameters we need to pass in JCL for restarting the IMS DB program?

Any one have an idea about check point restart logic in IMS?

Ensure the step is BMP and the program is BMP.
Also in the program make sure your code issues XRST call and decides whether the flow should be in normal or restart mode.

Hi,
Once issuing XRST in the program which will decides the call is normal call or Restart call please give the following parameter in the program

//STEP2 EXEC V01OIMSB,PROG=A1A3CKPT,PSB=HV01PTGW,
// AGN=P54ZAP
// UNITSYS=B,IMSLOGR=,
// RUNO=02,OLDRUNO=01,CHKPID=0621357

give the actual ckpt id in CHKPID parameter once the job abends
.Wen the job abends at first use the sample above , after restarting if it seems to be abend next time ensure and use the actual RUNO and OLDRUNO

Hi,

For checkpoint-restart call, you need to issue a RESTART parameter in the JCL and also a CHKPID parameter. In the normal run do not use RESTART parameter and use CHKPID = ''.
But when you restart, issue RESTART = stepname followed by CHKPID = LAST.

This will help the job to re-start from the last checkpoint. Also tghe XRST call in the program will help in saving all the values that will be needed to continue from that point when the program would have abended.

Thanks.
