//
// Description:
// Registration and make element READY for z/OS ARM (Automatic Restart Manager).
//
// Function:
//            a) do the registration with ARM
//            b) make the element READY for ARM
//
//    All errors are handled inside this routine, a failure to register or
//    a failure to make READY the element does not impact the further function
//    of the CIM Server. The success and failures are written to the
//    z/OS console and the appropriate CIM Server logs.
//
//    The registration status is saved in the global variable ARM_zOS_Status
//    for further use ( e.g. actions after a restart) within the CIM Server.
