How to prioritize messages in XI
Some scenarios require processing messages with priority; these situations can be managed by sending them to a queue of higher priority.
The following transactions will be used:
The process to prioritize a message goes as follows:
So first we need to configure IDs for the sender service and/or for the receiver service. After creating a new entry we’ll need to define at least the following fields:
In this weblog I’ll show how to prioritize a message in an outbound queue, so a sender and a receiver must be defined. When using an inbound queue just the sender is needed. The following image shows the configuration:
Next we’ll configure the filter to prioritize all the messages which come from the Sender ID and which are send to the Receiver ID that we defined.
After adding the filter we should have a table like the following:
Finally the filter has to be activated; therefore the row should show the “active” status.
In order to check whether the message is being sent to the right queue we can monitor the messages in SXMB_MONI. The messages should be sent to the right queue after the activation.
The queue XBTL, which handles large messages, can’t be deactivated or deleted because it is in charge of maintaining the processor workload stable. The parameter EO_MSG_SIZE_LIMIT can be configured to define what a large message size is. Please read carefully the XI Tuning Guide if you are planning to change this criteria.
