DFS2342E IMS ver.rel REQUIRES facility
Explanation
An IMS control region or an IMS batch or DCCTL batch address space could not be started because IMS required a system facility that was unavailable. Facilities that prevent IMS from starting can include hardware (including not having a particular hardware level or facility) and software (including not having a required software component installed or at the correct level).
The information in the messages is:
- ver.rel
- The IMS installed version and release level.
- facility
- The facility IMS needed that
was unavailable. The value of facility can be one of the following:
- Z/ARCHITECTURE MODE
- IMS can only run on processors running in z/Architecture® mode. ESA and below is no longer supported. You must either re-IPL your z/OS® system in z/Architecture mode, or you must move the IMS address space to a different machine that is running in z/Architecture mode.
- 64-BIT VIRTUAL SUPPORT
- You can only run IMS on a z/OS release that has 64-bit virtual storage support. If you receive this message, then you are running IMS under a non-supported z/OS level that does not allow 64-bit virtual storage. You must upgrade your z/OS to the minimum level for the current release of IMS.
- SYSTEM ZEC12 OR HIGHER
- IMS installed release 15.4 can execute only on a System zEC12 processor (machine type 2827) or above. See the IMS Version 15.4 Release Planning for a complete list of supported processors.
System action
IMS terminates with an abend 0071, and the address space does not start.
System programmer response
Make the facility indicated available on the machine on which you run IMS, or else run IMS on a different machine that has the indicated facility.
