sys.zOS.IMSDatabase

IMS databases.

Attributes

CDM attribute	Value	Example
Name	Name of the database
DatabaseType	Enumeration: Database, Area, Partition Database: A database provides for the storing and control of business data, independent from (but not separate from the processing requirements of) one or more applications. The database records details (attributes) of particular items (entities) and the relationships between the different types of entities. IMS uses a hierarchical model as the basic method of storing data. Area: Data entry databases (DEDBs) provide efficient storage for and access to large volumes of data. DEDBs also provide a high level of availability of that data. A DEDB can be organized into one or more data sets called areas. Each area contains the entire data structure. Partition: HALDB allows the grouping of DL/I database records into sets of partitions that are treated as a single database while permitting functions to be performed independently for each partition. Each HALDB partition has the same capacity limit as a DL/I non-HALDB database.

Requirements for discovery

Filtering enabled. By default this is SUPPRESSED since there may be many instances. Note that the sys.zOS.IMSSubsystem attribute DatabasesChecksum enables CMDB to detect Database changes without needing to populate many sys.zOS.IMSDatabase instances.
IMS subsystem and related address spaces must be active and fully initialized.
The DLA must be running in APF authorized mode.
