RUN TASK Checkpoint/Restart
Connect:Direct® for z/OS® also offers a checkpoint/restart feature with the RUN TASK Process statement.
If a RUN TASK program is executing on the SNODE and a session failure occurs, the PNODE recognizes the session failure and puts the Process in the Timer queue for retry. The SNODE, however, is still running the RUN TASK program and is not aware of the session failure until the program finishes. The checkpoint/restart feature for RUN TASK ensures that when the Process restarts on the PNODE, the RUN TASK program does not execute a second time on the SNODE.
