Managing Registrations
Registration is the procedure by which programmatic information about processes,
users, and so on, created in the process development workshops, is made available
to a running iIS process engine, so it can be dynamically loaded and used in
process execution. The programmatic information usually consists of programs
(shared libraries) created in the iIS process development workshops, but can also
be logical references to executing processes, called aliases.
This chapter describes how to manage iIS process engine registrations. It covers the
following topics:
• overview of registration concepts
• how to register iIS library distributions
• how to register an alias
• how to perform application upgrades
About Registration
The iIS process engine’s principal function is to execute process definitions created
in the iIS process development workshops. A process definition is a program that
specifies how the engine coordinates the various client applications and resources
that perform the work needed to complete a business process.
Most businesses are not static, but rather are dynamic: they want to create new
business processes or modify existing ones. The organizational structure might
also change, impacting how work gets assigned. To provide the flexibility
businesses require, the engine can dynamically load and execute new and revised
process definitions, assignment rules, and other programmatic information.
