Discovering changes to the system model

From time to time you might want to update your system model to keep it in step with changes that have taken place on the system. You can discover new MVS™ images on your sysplex, new CICS® resources and subsystems on MVS images, and new CICSPlex® SM elements on your WUI. The first time you perform discovery on an MVS image, all CICS resources and subsystems are discovered and the model is populated. When you perform a rediscovery on an image you must also perform rediscovery on the WUI servers as well to discover and integrate the new CICSPlex SM elements.

Discovering new MVS images

About this task

The following steps explain how to discover any new MVS images on the sysplex and add them to your existing system model.

Procedure

  1. In the DA Projects view, expand the project that contains the system model. Right-click the sysplex name and click Discover MVS Images. CICS DA performs a discovery to find additional MVS images on the sysplex. The Rediscover MVS Images dialog shows the new images and the existing workspace images.

  2. Select one or more images you want to add to the model and click Add. The images move across to the right.
  3. Click Finish. CICS DA adds the images to the model. You must now discover the CICS resources and subsystems on the MVS image. The next procedures outline the additional steps you must perform.

Discovering new CICS resources and subsystems

About this task

The following steps explain how to discover any new CICS resources and subsystems on an MVS image in your system model, and add them to the model. You can perform discovery on only one image at a time.

Procedure

  1. In the DA Projects view, expand the project that contains the system model. Right-click the MVS image name and click Discover Subsystems. CICS DA performs a discovery to find all the CICS resources and subsystems on the MVS image. It compares the information with the existing model and displays any differences in the dialog.

  2. Click Finish to add the changes to the model.

If you are performing these steps because you added a new MVS image to your model, all the CICS resources and subsystems are added to the model when you click Finish. If the MVS image already exists in your model and you are checking for updates, then you must discover the CICSPlex SM elements on your WUIs as well. The next procedure outlines the additional steps you must perform

Discovering new CICSplex resources on a WUI

About this task

The following steps explain how to discover any new CICSplex resources on a WUI in your system model, and add them to the model. You can perform discovery on only one WUI at a time.

Procedure

  1. In the DA Projects view, expand the project that contains the system model and the CICSPlex SM Web User Interface Servers tree. Right-click the name of the WUI you want to update and click Discover CICSplex resources. CICS DA performs a discovery to find all the CICSplexes and Groups on the WUI. It compares the information with the existing model and displays any differences in the dialog.
  2. Click Finish to add the changes to the model.

The changes are applied to the model and can be seen in the DA Projects view.
