Viewing the system model in the visualization views

The visualization views provide a graphical representation of the system model. The three visualization views use the same model data, but each view shows the data in a different way. You can use the Expand all and Collapse all icons to view the content of the Sysplex and MVS™ images, and open the objects to access more detailed information.

To open a visualization view, right-click the connection name in the DA Explorer view, then hovering over Open Visualization, and select a view from the list shown.

Each view consists of a container object that represents the sysplex. The sysplex name is shown, and an icon that indicates the number of MVS images in the sysplex. In the following example, the sysplex name is Plex2 and it contains nine MVS images.

When the sysplex container is expanded, the MVS images are shown as container objects in the sysplex container. There is one object for every MVS image. In the following example, two MVS image containers, MV26 and MV27 are shown.

The MVS images are expanded showing a container object for each image. Each MVS image container object shows a number of icons, each icon represents the model elements in the MVS image.

Each MVS image container object shows the name of the MVS image and a number of icons, which represents the model elements in that MVS image A screen capture that shows the overview icons. You can hover over the icons to see the type of model element they represent.

When an MVS image container is expanded, the model elements are shown as individual objects. Each object shows the name of the model element and other related information. You can hover over an object to show more information, or double-click an object to open it in the resource-specific editor.

The MVS images are expanded showing a container object for each image. Each MVS image container object shows a number of icons, each icon represents the model elements in the MVS image. One of the MVS images is expanded and shows the individual model elements in the MVS image. Each element is represented by a single object.

The last known status of each element is indicated by a decorator on the element icon, and by the element color. The following example screen captures show the three possible statuses that you might see:

Running status: An example of a resource element where the last known status is running. The status is indicated by the green decorator on the icon. Stopped status: An example of a resource element where the last known status is stopped. The status is indicated by the red decorator on the icon. Unknown status: An example of a resource element where the last known status is unknown. The status is indicated by the question mark decorator on the icon.
Note: A status of unknown can occur if you have CICS regions with duplicate job names, and the CICS DA model is out of sync with the system. If you see an unknown status, it can be resolved by running a discovery action and reloading the model to refresh the status. However it is possible that the unknown status will return if the condition that caused it reoccurs. The last known status is only an indication and can be safely ignored. For an accurate status, you should always use your CICS monitoring tool.

The layout of the individual model elements depends on which visualization view is open. The layouts are described in the individual topics:
