You can stop a CICS region using CICS DA.
Before you can stop a CICS® region, you must have an active CICS DA connection. You must also have performed a system discovery and have a copy of the model on your local computer.
This task stops a CICS region.
If a region is running the region icon in the model is decorated with
a green triangle. If the region is not running,
the green triangle is not present. When you stop a CICS region, the region stops in a controlled
manner; that is, any tasks that are running will complete before the
region stops. This task might not stop a region that is not running
correctly.
The CICS region stops. You might have to refresh the model before you see the CICS region icon change status. To refresh the model right-click the project name and click Refresh. CICS DA writes a message to the Console view recording the action.
