Updating the subsystem name table

To ensure the availability of an SSID to use for the RTCS subsystem, update the z/OS subsystem name (SSN) table. If you are sharing data sets, you must complete this task only once per sysplex. Otherwise, complete this task for each of the target z/OS images.

  1. Add the selected SSID to the IEFSSNxx member in SYS1.PARMLIB or to the required Logical PARMLIB data set for the target z/OS image.

    Example

    The following is an example of adding subsystem entries to parmlib IEFSSNxx:

    SUBSYS SUBNAME(RTCS)
  2. Update the z/OS Subsystem Name Table by either performing an IPL of the target z/OS image or by using the following z/OS operator command:SETSSI ADD,SUBNAME=RTCS
