Defining groups for data sharing environments
IMS systems that belong to a data sharing environment must be defined to an IMS Group.
After you have defined all of the IMS systems, the IMS Group Display panel allows you to: define a group with the IMS systems in a data sharing environment; view IMS Recovery Expert group names that have been created; and add a new IMS Recovery Expert group, delete or rename a IMS Recovery Expert group, or update system associations.
Restrictions:
- All IMS systems belonging to an IMS group must belong to the same IMSplex.
- All IMS systems belonging to an IMS group must share the same RECON data sets.
- All databases handled by IMS Recovery Expert must be registered in RECON data sets and defined to all IMS systems of an IMS group.
- All IMS systems belonging to an IMS group must have the same settings for the following keywords
in the DFSDFxxx member of IMS PROCLIB:
- CATALOG= keyword: IMS catalog database enablement
- ALIAS= keyword: IMS catalog database alias name
- ACBMGMT= keyword: IMS-managed ACBs environment enablement
Procedure
- Specify 3 on the
Administration Menu panel (BSY$PLN0) and press Enter.
