ZOSTASK discovery

The ZOSTASK book contains address space details and relationships. By default only started class address spaces are discovered. System, batch job and TSO users can also be discovered via DLA configuration options.

Known address spaces are identified by their functionality. Their functionality is determined by a signature defined by using the program name and contents of the start parameters.

The following diagram shows the classes and relationships that are populated in the ZOSTASK book. The boxes that are clear are not populated.

ZOSTASK—AddressSpace details and relationships

See Appendix C. z/OS DLA data model class types represented in CDM for details on the attributes and relationships are discovered for these classes.

Note:
  1. The z/OS®, DB2® Data Sharing Group, DB2 Subsystem, IMS Subsystem, MQ Subsystem, CICS® Region and WebsShere Server instances are stubs. The instances contain enough information to identify the instance and are populated for naming rules or relationships with the address spaces. Other books are used to provide full details about these instances.
  2. A consolidated list of DASD volumes accessed by the address space is deduced from the allocations and is used to populate relationships to the StorageVolume instances.
