Supported operating systems

IBM® Automatic Binary Optimizer for z/OS® can be run on the following operating systems:
  • z/OS 3.1
  • z/OS 2.5
  • z/OS 2.4
  • z/OS 2.3

Some PTFs are required 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.

These PTFs are required on systems where ABO is running:
  • z/OS 2.5
    • OA63070/UJ90046 (Binder)
  • z/OS 2.4
    • OA57354/UJ04427 (Binder)
    • OA59816/UJ04608 (Binder)
    • OA63070/UJ90045 (Binder)
  • z/OS 2.3
    • OA55985/UA97356 (Binder)
    • OA57354/UJ04426 (Binder)
    • OA59816/UJ04607 (Binder)
    • OA63070/UJ90044 (Binder)
These PTFs are required on systems where ABO optimized modules are running:
  • z/OS 2.4
    • PH15921/UI65058 (Language Environment®)1
    • PH15921/UI65059 (Language Environment - Japanese)1
    • PH14705/UI64418 (Language Environment Automatic Binary Optimizer Runtime Engine)1
  • z/OS 2.3
    • PI84561/UI49013 (Language Environment Automatic Binary Optimizer Runtime Engine)1
    • PH14705/UI64417 (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 the 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.
