Performing Application Upgrades

However, sometimes an upgrade involves a new or modified extended user
profile. If this is the case, then the user profile, the validation and the assignment
rule dictionaries that depend upon it, and client applications that reference it might
all need to be upgraded. This type of upgrade has a broader impact, especially if
you cannot shut down your engine to perform the upgrade.
Monolithic Upgrades
In a monolithic upgrade, your developers create an upgraded user profile and
validation, upgraded assignment rule dictionaries, and upgraded client
applications that are not compatible with the earlier versions. You must shut down
your business process application to perform the upgrade.
➤
To perform a monolithic upgrade
1.
All client applications and application proxies must close their sessions with
the engine and shut down.
2.
Unregister current assignment rule dictionaries and the user profile.
The validation does not need to be unregistered (in fact, it cannot be). Do not
unregister process definitions.
3.
Deploy each upgraded client application to all nodes supporting that client
application.
4.
Register the upgraded user profile, validation, and assignment rule
dictionaries.
5.
Register upgraded process definitions, if an upgrade is necessary.
6.
Users can then start their upgraded client applications, open sessions with the
engine, and resume work.
