Versions of IOCP

Four versions of IOCP are available; three are batch versions (or operating system versions), and one is a stand-alone version (available on CPC Support Element). They are as follows:
  • Batch versions (or Operating system versions)
    • z/OS®
    • VM
    • z/VSE®
  • Stand-Alone version
Batch versions of IOCP have an advantage over the stand-alone version. You can modify an IOCDS while other system operations continue. Then, at a convenient time, perform the following steps:
  1. Shut down your operating systems
  2. Perform a power-on reset on the CPC (with the new IOCDS)
  3. Activate your logical partitions
  4. Reload your operating systems.
This method minimizes the amount of time that the system must be inactive while you reconfigure the I/O devices.
