Managing workloads

Your workload environment is set up and managed using the objects described in Table 4.

Table 4. Workload management objects
Object name Description Function
DTRINGRP Transactions in transaction groups This object displays information about the transactions associated with one or more transaction groups.
TRANGRP Transaction groups A transaction group is an association of logically similar transactions. The similarity may be based on affinity requirements, common shared processing requirements, or any other user-determined characteristics. The transaction group is included as part of the workload definition, which in turn defines the CICS® system group to be used as the target region. Any transaction that is not specifically associated with a transaction group is assigned to the default transaction group.
WLMATAFD Transaction affinities for an active workload This object shows a detailed display of the properties of any single active affinity. This is useful, for example, when you need to view the contents of a CICS BTS affinity key in hexadecimal format.
WLMATAFF Transaction affinities for an active workload This object shows information about the active affinities for a transaction group associated with a workload within the CICSplex identified as the context. An affinity becomes active when the first transaction associated with the transaction group is dynamically routed to a target region.
WLMATAFS Summary of transaction affinities This object, which is the summary form of the WLMATAFF object, shows summarized information about the active affinities for a transaction group associated with a workload with the CICSplex identified as the context.
WLMATGRP Transaction groups associated with an active workload This object shows information about transaction groups associated with a workload that is within the CICSplex identified as the context.
WLMATRAN Transactions associated with an active workload This object shows information about all active transactions associated with a workload that is within the CICSplex identified as the context.
WLMAWAOR Target regions in an active workload This object shows information about all target regions that are associated with a workload that is within the CICSplex identified as the context.
WLMAWAOS Target regions in an active workload summary This object shows summarized information about all target regions that are associated with a workload that is within the CICSplex identified as the context.
WLMAWDEF Active workload definitions This object shows information about active workload definitions associated with a workload that is within the CICSplex identified as the context.
WLMAWORD Details of an active workload This object shows information about an active workload within the CICSplex identified as the context. A workload is active within a CICSplex as long as:
  • A CICS system that is acting as a routing region or target region, and is participating in the workload, is connected to that CICSplex.
  • Any transaction causes an affinity lifetime of PERMANENT to be established.
WLMAWORK Active workloads This object shows information about active workloads within the CICSplex identified as the context. A workload is active within a CICSplex as long as:
  • A CICS system that is acting as a routing region or target region, and is participating in the workload, is connected to that CICSplex.
  • Any transaction causes an affinity lifetime of PERMANENT to be established.
WLMAWTOR Routing regions in an active workload This object shows information about routing regions that are associated with a workload that is within the CICSplex identified as the context.
WLMAWTOS Routing regions in an active workload This object shows summarized information about routing regions that are associated with a workload that is within the CICSplex identified as the context.
WLMDEF Workload definitions This object identifies which transactions are to be routed to which CICS system group. You identify the transactions by transaction group, and within the group either by LU name and user id, or by process type.
WLMGROUP Workload groups This object is used to associate one or more workload definitions.
WLMINGRP Workload definitions in workload groups This object displays the names of workload groups and the workload definitions associated with them.
WLMINSPC Workload groups in workload specifications This object displays the names of workload specifications and the workload groups associated with them.
WLMSCOPE Workload specifications assigned a scope This object displays information about the CICS systems or CICS system groups acting as routing regions that are associated with a named workload specification.
WLMSPEC Workload specifications A workload specification identifies a workload and one or more CICS system groups acting as target regions. It also defines the attributes of the default transaction group.

The WLM object model is shown in Figure 19.

Figure 19. The WLM object model
The diagram shows the relationship between the views used to establish and maintain a workload and their functions. The CICSSYS view defines and maintains system definitions and specifies whether the CICS system is to act as a routing region or a target region for dynamic routing. The CICSGRP view defines and maintains CICS system group definitions. WLMSCOPE associates a TOR scope with workload specification. WLMSPEC defines and maintains a workload specification. WLMINSPC associates a workload group with a workload specification. WLMGROUP defins and maintains a workload group. WLMINGRP associates a workload definition with a workload group. WLMDEF defines and maintains a wokload definition. TRANGRP defines and maintains a transaction group. DTRINGRP associates a transaction definition with a transaction group. These views are described in the preceding text in the discussion of WLM management.
