Keep the following two requirements in mind when determining installation requirements and packaging for resource type packages:
When a new resource type is registered, its RTR file must be accessible on disk.
When a resource of the new type is created, all declared method path names and the monitor program for the new type must be on disk and be executable. The old method and monitor programs must remain in place as long as the resource is in use.
To determine the correct packaging to use, consider the following questions:
Does the RTR file change?
Does the default value or tunability of a property change?
Does the min or max value of a property change?
Does the upgrade add or delete properties?
Does the monitor code change?
Does the method code change?
Are the new methods, the monitor code, or both compatible with the previous versions?
The answers to these questions will help you determine the correct packaging to use for your new resource type.
