    Hi Damodar,

    Its depen on your OS.

    For windows you can use scheduler

    For Unix you can use cron

    Central instance = message server, this control all the application like load balancing its control from central instance.

    And you can only have 1 central instance in a system, but you can have more than 1 for application server.

    Application server is an additional instance to help the load.

    NB: Next time please put more information in your Subject.

    Hi Damodar,

    Fendi is right but still i want to add that Central instance has Enqueue Server apart from Message Server and Application server is dialog instance with WPs like dialog, backgroun etc to balance the Load.

    Hope this is useful

    Regards

    Umesh

    To lock a client use the following functional module

    SCCR_LOCK_CLIENT

    SCCR_UNLOCK_CLIENT
