Both types of publication use the IAPJMS (Introspection Activity Publication JMS) process, but they differ in detail.
An activity is any instruction in the TIBCO iProcess Engine that creates an audit trail entry, for example, Case started or
Event issued. You can configure any combination of step and/or activity to be monitored. This enables an external application to monitor important business events during the processing of cases.
The BG process can identify if a step is being processed and if activity monitoring has been configured for it. The
BG process then sends details of the configured activities, in XML format to the
IAPJMS Process.
The IAPJMS process sends the XML message to a specified JMS topic, from which an external application can receive the XML format message.
If any data in a monitored work queue changes - for example if an existing work item is modified, an existing work item is removed from the work queue or a new item is added to the work queue - the Work Item Server (WIS) process sends the modified data in XML format to the
IAPJMS process. The
IAPJMS process then sends the XML message on to a specified JMS topic (either a default topic, or one specified by the subscribing application), from which an external application can receive the XML message.
