Manage groups with MQSeries or JMS

To manage groups, you must set further parameters in addition to those required for the basic implementation.

The message context must follow the following rules:

Each message that is to be sent must obey the following rules:

The data carried by the Input-Event message must be formatted as shown in the following table:

Define a complete group

A group of Input-Events is complete when:

• The system finishes reading the last message in the group (end-of-group flag = F)
• The number of messages processed with the same CorrelId equals the sequence number in the final message of the group

Define an incomplete group

A group is incomplete if one of the above conditions is not fulfilled.

Each time the system receives an incomplete group, it checks the incomplete groups queue. If it finds the remainder of the group in this queue, it processes the entire group. Otherwise, the system sends messages to this queue until it receives the remaining messages.

Reproduce a group

To reproduce a group, you write the CorrelId of the processed Input-Event group back into the contexts of the output messages.

Rule Engine automatically reproduces Input-Event groups for queues that contain:

• Input-Events placed in anomaly during transformation
• Rejected Events
• Modified Input-Events
• Redirected Input-Events

Reproducing groups is optional for queues of Output-Events generated by the transformation of an Input-Event group. The system reproduces groups for each queue declared in script.mqs or script.jms.

Parameter settings in script.mqs or script.jms for a queue of Output-Events

Queue= MQS , "Manager=Qmngr;Queue=queuename; Reproduction_group=Yes;Blocking=Yes;"

Rules to follow:
