Class/Instance Link Considerations

You should be aware of the following when making links between classes and instances:

• Only applications with either the same category or no category specification can be in a link chain
• Category-specific policies are only available if the category is specified explicitly rather than inherited

For example, the IMS CONTROL policy item is available for an application of category IMS. It is not available, however, for an application that does not have a category specification but is linked to a class of category IMS.

Thus, if an application without a category is linked to a class with a category specification, you should be aware that you can only specify category-specific data for the class, but it will be inherited by the instance.

Furthermore, if you need to specify category-specific data at the application level, you must specify the category for the application.
