Chapter 2 Using the TIBCO Object Service Broker Development Environment : Messaging Mechanisms

Messaging Mechanisms
TIBCO Object Service Broker provides two types of messaging mechanisms from the workbench:
Broadcast Message
An administrator would use the broadcast message table to convey a message to all users when they first log in to TIBCO Object Service Broker. It appears at the bottom of the workbench next to the time, when you first log in to the system.
The message text for the broadcast message is obtained from the BROADCAST table, which is a TIBCO Object Service Broker table. The occurrence with the highest primary key (the NUMBER field) appears on the workbench. You can view the complete table by pressing PF2 before you start another transactions in your current TIBCO Object Service Broker session. If the table is empty, the message “no broadcast available” appears.
BROADCAST Table Illustrated
The following screen shows an occurrence from the BROADCAST table:

Message Logs
 
TIBCO Object Service Broker maintains two message logs that you can view when you press PF2:
See Also
TIBCO Object Service Broker Programming in Rules for information about the message logs.
System Log
When a rule fails in its execution and the error is not trapped in the rules program, error messages and debugging information for that transaction are supplied in the system log. Using the information from the system log, you can make corrections to your rule so that it executes successfully.
User Log
The user log contains the messages generated by a rule and the output generated by a transaction (parent) and its descendant (child) transactions. Only output from the most recent transaction plus that from the next higher level are available, because output from the previous lower-level transaction is cleared when a new one begins.
Messages from the system log appear first; pressing PF2 again displays the user log. If the system log is empty, the user log appears after the first time you press PF2.
