Control program support in a logical partition

Edit online

Control programs require certain characteristics. Before planning or defining LP characteristics, call your installation management to determine which control programs are in use or planned for operation.

Notes:

  1. z/OS support is often delivered in service (PTFs) for z17, which have been identified using SMP/E fix categories (FIXCATs). These FIXCATs can be used to identify minimum required service, additional recommended service, and service needed for exploitation.

    The minimum required PTFs for z/OS have been identified with the SMP/E FIXCATs for each appropriate model:
    • IBM.Device.Server.z17-9175.RequiredService.
    PTFs that are recommended to be installed by the IBM service organization are identified for the appropriate model with the following SMP/E FIXCATs for each appropriate model:
    • IBM.Device.Server.z17-9175.RecommendedService.
    IBM z17 exploitation functions, which you may choose to use later after your initial upgrade, have been identified by the appropriate model with the following SMP/E FIXCATs for each appropriate model:
    • IBM.Device.Server.z17-9175.Exploitation.

    Use the SMP/E REPORT MISSINGFIX command with the latest Enhanced HOLDDATA to quickly and easily identify any PTFs that are missing on your system for the category you are interested in. For more information on z/OS support for z17, see the z/OS z17 Upgrade Workflow, available at https://www.ibm.com/docs/en/zos/3.1.0?topic=consider-zos-upgrade-workflows.
