When the CICS® DA server runs a discovery operation, it adds all active elements to the model. If a CICS region, or other element, is later deleted from the z/OS® system, it remains in the model. The CICS DA server cannot tell if a model element is inactive, or if it no longer exists in the z/OS system. For this reason, the server does not delete elements from the model. You can manually delete an element, or elements, from the CICS DA model.
When you select an element to delete, any associated connections and resources are also deleted. For example, if you delete a CICSplex, all CICS regions and connections in the CICSplex are deleted
Deleting an element from the model does not delete the element from the system. If the element exists on the z/OS system and is active, then the next time a discovery is run the element is added to the model.
If you want to delete one or more tags from all the resources in the model, you must select the tag in the DA Explorer Tagged view.
The model element, or elements, is deleted. An entry is written to the audit log identifying the date, time, and user ID that requested the delete.
