Keeping the local model synchronized with the server

In CICS® DA terms, a model is a collection of all the system information that is identified when the CICS DA discovery process is run against a sysplex. The model is maintained by the CICS DA server. You can load a copy of the model into your local workspace and use the CICS DA client to visualize and understand your CICS environment. The same model can be loaded by multiple users.

Any changes that you, or any other users, make to the local model are also applied to the model on the server. If a user reloads the model on their machine, then they see the changes that you made. Similarly, if you reload the model, then you see any changes that other users made.

It is possible for two users to independently update the server model, which can result in a user local model that is out of sync with the server model. If the local and server models are out of sync, you might see an error message the next time that you work with the model. Alternatively, you might have other symptoms, such as the text <missing names> showing instead of the model element name in the model tree, or Unknown status showing in the visualization views.

If you see either of these symptoms, or you have other problems with the model, reload the model on your machine. If you still see the symptoms, run a new discovery and reload the new model.

When discovery runs, the existing server model is not deleted, so all tags and start policies are retained. Any new elements that are discovered are added to the existing model.
