Getting Started
Follow the steps below to configure Zowe CICS IA Explorer.
- Loading the CICS IA Profiles from CICS Profiles
- Create a New CICS IA Profile
- Update CICS IA Profile
Loading CICS IA profiles from CICS profiles
By Default, CICS profiles from CICS VS Code extension is loaded into CICS IA View.
Below is the Configuration screen for creating a new CICS profile.
After Creating a new CICS Profile refresh CICS IA view, we should be able to see the newly created CICS profile getting loaded automatically under CICS IA view as well.
The CICS IA tree view should show all the CICS profiles created in CICS Extension
*NOTE: If the CICS connection is failing with red indicator icon then that CICS profile should fail in the CICS IA view also.
Create New CICS IA Profile
Click on the ‘+’ icon next to existing CICS IA profile and in editor window a panel opens. Provide the Hostname, Port, and Protocol of server where IA Rest APIs are running.
Click on the Update Profile button.
Once the IA profile is created, CICS IA view will start loading the data from the DB Schema (Schema details are configured on Rest API WebSphere server running on mainframe) and creates the tree hierarchy inside the CICS IA Profile.
Update CICS IA Profile
Click on the yellow highlighted icon and in right side editor window a panel opens with existing profile details. Update the details that you want to alter.
Click on the Update Profile button.
Once the IA profile is updated, again CICS IA view will start loading the data from the DB Schema (Schema details are configured on Rest API WebSphere server running on mainframe) and refreshes the tree hierarchy inside the updated CICS IA Profile.
CICS IA Profile
CICS IA profile upon successful connection displays Green indicator icon over the profile name. If connection not successful, then displays Red indicator icon over the profile name. CICS IA profile on Successful connection extracts the Collected Dependency and Affinity data from the DB2 Schema to which REST API is configured. When CICS IA profile node is expanded, below child items are listed.
Collection IDs: Collected data has been grouped under Collection IDs and is used for analysing the collected data. For more information, See Collection IDs.

- The Middle Pane displays Program/Transaction in which the selected resource is invoked.
- The right Pane displays tree hierarchy for the resource usage grouped by Regions.
Affinities view
The Affinities view displays an alphabetical list of resources with potential affinities related to the target object.
CICS® transactions and programs use some techniques to exchange data that require those transactions or programs to run in the same CICS region, or in a specific CICS region. The result of such requirements is restrictions on the regions to which transactions and distributed program link (DPL) requests can be dynamically routed. If transactions or programs exchange data in ways that impose such restrictions, these are known as affinities between them.
The affinity-related functions of CICS IA have the following uses:
- Users of CICS dynamic routing can determine whether any transactions in their CICS applications have an inter-transaction affinity (some transactions must run in the same region) or a transaction-system affinity (some transactions must run in a specific region).
- Application programmers can detect whether a program being developed might cause transaction affinities.
Right-click the item that you want to view the affinities for and click Show Affinities By Type. The Show Affinities By Type menu is linked to the type of object that is currently selected, rather than the view the object is in. You can also right-click an item in the Programs or Transactions node to display the affinities menu items.
The Affinities view includes 2 sections.
- The upper section displays either,
- Affinity Group or
- Resource, the affinity relation type, Lifetime of affinity or
- Affinity relation type, Lifetime of affinity
- Upon selection of an item in the upper section, the lower section displays the Transaction, Program and Command resulting in the selected affinity type.
