SSM crash and reboot

WHen SSM crash happen, after the dump creation, the service must restart automaticaly. At same times, VEMKD should detect this crash and send all applications that was to this SSM to another one and ask to the client to submit again the workload without recovery OR wait until x minutes until SSM restart to restart calculation with recovery

    There are four environment variables that you can define on your client to influence how the client behaves when it loses its connection to the session manager, e.g., change the configuration to wait for SSM restart.





    Refer to IBM Documentation for the detail.

    When client connection is kept until SSM restart, the recoverable session or workload submitted thought SMC can continue the calculation.

    However, for "unrecoverable sessions" and submit to silo symphony cluster directly, the existing sessions will exit due to SSM crash, symphony client needs to handle this via re-created the affected sessions.

    Let's know if anyhting is not clear.

    Thanks, Dennis
