Search Tips   |   Advanced Search


ActivitySessions are a WebSphere extension to reduce the complexity of commitment rules and limitations that are associated with one-phase commit resources.

The ActivitySession service

The ActivitySession service provides an alternative unit-of-work (UOW) scope to that provided by global transaction contexts. An ActivitySession context can be longer-lived than a global transaction context and can encapsulate global transactions.

ActivitySession service APIs

The ActivitySession service consists of an API available to Web apps, session enterprise beans, and client applications, which we can use for application-managed demarcation of ActivitySession context.
