Migrating the production environment

To migrate your production system, perform the following steps:

  1. If you migrate your z/OS operating system to a newer version, reassemble the SMF and JES exits mentioned in Add SMF and JES event tracking exits with the libraries of the new operating system.
  2. Install the new release of the IBM Workload Scheduler Agent for z/OS.
  3. Close down your IBM Workload Scheduler Agent for z/OS production system:
    1. From the master production system, set limit=0 to the Agent Workstation on IBM Workload Scheduler Agent for z/OS master domain manager.
    2. Wait until no jobs are in execution and stop the IBM Workload Scheduler Agent for z/OS.
  4. Edit the Started Task (job) of the production by changing the following DD statement pointing to the data sets installed with the new release of:
    • EELMLIB
    • STEPLIB
    • EELJCLIB
  5. Allocate the JCLIB running the EELINST
  6. Specify BUILDSSX (rebuild) and SSCMNAME (EELSSCMN, PERMANENT) in TWSOPTS parameters.
  7. Before the next IPL of the system, remove the BUILDSSX and SSCMNAME keywords from the agent initialization statements.
