Chapter 7 Administering Message Queues and Mbox Sets : Default Message Handling Configuration

Default Message Handling Configuration
This section describes the message handling configuration that is used on a default iProcess Engine installation.
Default Mbox Sets
The following table shows the default Mbox sets that are created when iProcess Engine is installed. See Show Mbox Sets for an explanation of the Mboxset ID, Mboxset Name and Queues in Mboxset columns.
Default Message Queues
The following sections describe the default message queues that are created when iProcess Engine is installed on a Windows or UNIX system. See Add a Message Queue for an explanation of the Queue Name and Queue Description columns.
Windows/SQL Server or UNIX/DB2
The following tables shows the default message queues that are created when iProcess Engine is installed on a Windows/SQL Server or UNIX/DB2 system.
UNIX/Oracle or Windows/Oracle
The following table shows the default Oracle AQ message queues that are created when iProcess Engine is installed on a UNIX/Oracle or Windows/Oracle system.
How WIS Processes Send Messages to BG Processes
The following diagram shows how the WIS processes send messages to the BG processes using the default configuration.

 

 
1.
One WIS process is configured to write messages to each WISBGMBSET Mbox set.
2.
Each WISBGMBSET Mbox set contains a single message queue, BGMBOX.
3.
Two BG processes are configured to read messages from each WISBGMBSET Mbox set.
How non-WIS Processes Send Messages to BG Processes
The following diagram shows how non-WIS processes send messages to the BG processes using the default configuration.

 
 

 
1.
All non-WIS processes (such as swbatch) are configured to write messages to the BGMBSET Mbox set.
2.
The BGMBSET Mbox set contains two message queues, BGMBOX1 and BGMBOX2.
3.
All BG processes are configured to read messages from the BGMBSET Mbox set.
How BG Processes Send Messages to WIS Processes
The following diagram shows how the BG processes send messages to the WIS processes using the default configuration.

 

 
1.
All four BG processes are configured to write messages to a single Mbox set, WMDMBSET.
2.
The WMDMBSET Mbox set contains two message queues, WISMBOX1 and WISMBOX2.
3.
Both WISMBD processes are configured to read messages from the WMDMBSET Mbox set. (Each WISMBD process then forwards each message to the appropriate WIS process via RPC.)
How BG Processes Send Messages to the Prediction Process
The following diagram shows how the BG processes send messages to the BGPREDICT process using the default configuration.

 

 
1.
All four BG processes write messages to the PREDICTMBSET Mbox set.
2.
The PREDICTMBSET Mbox set contains two Mboxes, PREDICTMBOX1 and PREDICTMBOX2.
3.
The BGPREDICT process reads messages from the PREDICTMBSET Mbox set.
