Chapter 7 Monitoring Activities : Understanding the Message Types

Understanding the Message Types
Activity Monitoring (IAP) uses two message types, and Work Queue Delta publication (WQD) uses three types.
IAP Message Types
There are two types of message:
The Monitor Event Detail message (MED). A BG process sends this message. The message is addressed to the JMS topic configured in the IAPJMS_TOPICNAME process attribute.
The Monitor Event Detail Message (MED)
Every MED message sent from the IAPJMS process to the external application consists of:
These messages can be sent in either a basic format or an extended format. You can specify which format is used by setting the IAPSCHEMA parameter in the SWDIR\etc\staffcfg configuration file. See the section "Tuning the iProcess Engine Using SWDIR\etc\staffcfg Parameters" in the TIBCO iProcess Engine: Administrator’s Guide for details of this parameter.
The extended format provides the following additional information in the message body:
For examples of these IAPJMS messages, see the section "Examples of Configuring Activity Monitoring Information" in the TIBCO iProcess™ Modeler Integration Techniques guide.
Filtering Message Event Request (MER) Messages
Every MER message sent to the iProcess database to update the activity monitoring configuration information consists of XML requesting the events to monitor. The MER XML format is defined by the SWMonitorList.xsd schema.
WQD Message Types
There are three types of message:
The Work Queue Delta message (WQD). The WIS process sends this message.
Work Queue Delta (WQD) Message
Every WQD message sent from the WIS process consists of:
the message body containing details of the Work Queue Delta. The WQD XML format is defined by the apSSOTypes.xsd schema. See the section "Schemas" in the TIBCO iProcess™ Client (Browser) Action Processor Reference guide for more information on this schema.
Whenever an item is added, modified or deleted from a monitored work queue, a WQD message is published by the WIS to the IAPJMS process.
Work Queue Synchronization (DSY) Message
Every DSY message consists of.
A DSY message is sent once the initial queue has been built. It is published to subscribing applications so that the subscriber knows it needs to begin processing any Work Queue Deltas for the specified Work Queue Delta ID.
Work Queue Invalid (DER) Message
Every DER message consists of.
The message type is an exception message sent to all applications subscribing to the work queue on which an error occurs. It tells the subscribing applications that the Work Queue Deltas for this queue are now invalid and that this work queue must be closed and re-opened.
See the TIBCO iProcess Server Objects (.NET) Programmer's Guide and the TIBCO iProcess Server Objects (Java) Programmer's Guide for more detail on Work Queue Delta publication via JMS and how it works.
