Supported operating systems

IBM® Automatic Binary Optimizer for z/OS® can be run on the following operating systems:
  • z/OS Version 2.5
  • z/OS Version 2.4
  • z/OS Version 2.3
  • z/OS Version 2.2

For the operating system levels before z/OS 2.4, ABO requires some PTFs to be applied on the systems where Automatic Binary Optimizer for z/OS is installed and running. Other PTFs are required on systems where the ABO generated optimized modules will be running, even if ABO is not installed on these systems. APAR/PTF (OA47689/UA90982), which is available for z/OS 2.2 only, is required on systems where either ABO or the ABO generated modules are running.

These PTFs are required on systems where ABO is running:
  • z/OS V2.3
    • OA55985/UA97356 (Binder)
  • z/OS V2.2
    • OA47829/UA78084 (Binder)
    • OA50460/UA82866 (Binder)
    • OA47689/UA90982 (IEFOPZxx SYS1.PARMLIB support)
    • OA55985/UA97372 (Binder)
These PTFs are required on systems where ABO optimized modules are running:
  • z/OS V2.4
    • PH15921/UI65058 (Language Environment)1
    • PH15921/UI65059 (Language Environment - Japanese)1
    • PH14705/UI64418 (Language Environment Automatic Binary Optimizer Runtime Engine)1
  • z/OS V2.3
    • PI84561/UI49013 (Language Environment Automatic Binary Optimizer Runtime Engine)1
    • PH14705/UI64417 (Language Environment Automatic Binary Optimizer Runtime Engine)
  • z/OS V2.2
    • PI51546/UI33445 (Language Environment)
    • PI51802/UI32944 (Language Environment CICS® system definition sample update)
    • OA47689/UA90982 (IEFOPZxx SYS1.PARMLIB support)
    • PH14705/UI64419 (Language Environment Automatic Binary Optimizer Runtime Engine)
If the same system is going to be used to both run ABO and run the ABO optimized modules then all the PTFs listed above per z/OS version must be installed on this system.
Optional programs that can be used with ABO:

It is highly recommended that the latest IBM Automatic Binary Optimizer or IBM Automatic Binary Optimizer Trial PTFs be installed. See the fix list and new features page.

Note:
  1. The PTF is included in the GA or GA PTF versions of z/OS 2.3 and z/OS 2.4 so is only required if running early release versions of these z/OS levels.
