Registering iIS Distributions

Upgrading Registrations

Sometimes you must register a new version (upgrade a registration) of one of these library distributions. How you upgrade a registration depends on the upgrade registration characteristics of the distribution type, as summarized in the following table:

Distribution Type	Registration Characteristics
User profile	Cannot register upgraded versions of the same name unless
	you first unregister the older version, cold start the engine, or
	rename the upgraded version.
Validation	Can register upgraded versions of the same name. Engine
	supports only the most recent version—automatically
	unregisters earlier version.
Assignment rule	Can register upgraded versions of the same name. Engine
dictionary	supports only the most recent version, retroactively applying
	it to all existing activities.
Process definition	Can register upgraded versions of the same name. Engine
	supports multiple versions. Engine unregisters older versions
	no longer being used.

Unregistering iIS Distributions

At times you might want to unregister a distribution from one or more engines, normally because those engines no longer use the process definitions they contain. (You might also have to unregister a distribution because for some reason you want to re-register it.) Cold starting an engine unregisters all registrations; however, if you want to be more selective, use the procedure described in this section.

NOTE You cannot explicitly unregister a validation. This is because the engine maintains only one validation—registering a new validation implicitly unregisters the previous one.

You can unregister only one registered distribution at a time.
