Base configuration modules HRFSETOP and HRF#ssid
IMS Online Reorganization Facility uses customizable module HRFSETOP, HRF#ssid, or both to define base configuration parameters.
During IMS Online Reorganization Facility initialization, these modules are loaded from the STEPLIB concatenation in the IMS control region and the IMS Online Reorganization Facility address spaces. To create one or more base configuration modules, run the SAMPLIB member HRFCCNFG.
If you need a different set of base configuration
parameters for each IMS subsystem
or IMSPLEX, you can define multiple base configuration modules in
the same library. When you define multiple base configuration modules,
the member name of each additional module must begin with HRF#
and
use the suffix IMS ID or IMSGROUP.
When the STEPLIB concatenation of an IMS control region contains multiple base configuration modules, the modules are searched for in the following order:
- HRF#imsid
- HRF#imsgroup
- HRFSETOP
The control region uses the first base configuration module that is found.
In an IMS Online
Reorganization Facility job, use the OPTID
keyword with the REORG command to specify an IMS ID or an IMSGROUP. The default for the OPTID
keyword is IMSID
, which specifies that the IMSID
from DFSVC000 in RESLIB is the suffix for the base configuration module
name.
In the IMS Online Reorganization Facility jobs, base configuration modules are searched for in the following order:
- HRF#optid
- HRFSETOP
