The CICS Explorer V5.5 open beta, part of the CICS TS open beta, has been enhanced again — and this time, it allows you to understand your Workload Management definitions with the Workload Map!
A major feature of CICSPlex SM (CPSM) is Workload Management. This is a powerful way of routing work from region to region that gives you high availability and redundancy. Many users find that as their system topology gets bigger and bigger and they support more applications, the web of Workload Management definitions can get harder to understand. The new Workload Map view in the CICS Explorer V5.5 open beta allows you to picture the relationships between these definitions.
Opening the Workload Map
The Workload Map is a new view in CICS Explorer. It usually appears at the bottom of the screen, though you can move it wherever you like. To trigger the Workload Map view, select the Show in Workload Map command. This is in the right-click context menu of definitions that relate to workload management, and appears as toolbar buttons in the Workload Specification editor.
For example, suppose I want to discover whether my Workload Definitions (known as Routing Rules in CICS Explorer) for a Workload Specification are used in any other Workload Specifications. If the Workload Specification is active I right-click the Workload in the CICSplex Explorer and select Open Workload Specification, or if it’s inactive, I can just open the Workload Specification by double-clicking it in the CICSplex Explorer.
From here, I see an overview of this Workload Specification. In this case I’m particularly interested in the Routing Rules. I right-click on the second rule, ‘CICS 5.5+’, and select Show in Workload Map. This brings up the Workload Map view at the bottom of the window, and focuses it on the ‘CICS 5.5+’ Routing Rule.
The Workload Map shows all of the Routing Rule’s relationships. For a Routing Rule, that includes:
- the Transaction Group that the Routing Rule uses.
- the Workload Groups that the Routing Rule is in.
By expanding the tree, we can see further relationships. Let’s look for other Workload Specifications that use this Routing Rule:
Aha! Another Workload Specification uses this Routing Rule. Workload Specification ‘EXPWRK1’ uses it via Workload Group ‘Group 63’.
Changing the focus of the Workload Map
If you want to use separate Routing Rules for these two Workload Specifications, you might want to create a new Workload Group to contain the second Routing Rule. But are there other Routing Rules contained by Workload Group ‘Group 63’, that we need to decide whether to separate? To find out, focus the Workload Map view on Workload Group ‘Group 63’ by right-clicking it and selecting Show in Workload Map.
This action puts the Workload Group to the top of the tree, and shows its relationships. For a Workload Group, that includes:
- the Workload Specifications that use the Workload Group.
- The Routing Rules that the Workload Group contains.
By expanding the Rules section of the tree, we can see that this Workload Group is only used by one Routing Rule.
This ability to re-focus the Workload Map view to any of the definitions involved in workload management makes it a very powerful tool. If you’re familiar with the Map view in the CPSM Web User Interface, you’ll find this Workload Map view more capable. For example, it shows Transactions inside Transaction Groups. Additionally, it merges the ‘map left’ and ‘map right’ actions into a single view, showing you a full overview of a definition’s relationships.
