SAP MII 15 Message Listener asynchronous

[peterdewilde]

We are facing the issue that we sometimes are sending so many message to the SAP MII Message Listener that it cannot keep up, resulting in delays off up to 10 or 15 minutes. I noticed that the message are processed synchronously.

Is there are way to make MII process the incoming message asynchronously?

Peter,

At a certain patch level they added the ability to allocate a certain number of threads for parallel processing messages once they get to MII. There are also some good SAP notes out there that advise how to configure things to get better performance as far getting the messages to MII.

If you aren't already at the right patch level and can't upgrade you will probably have categorize your messages and process them with a background job.

You could try processing messages using asynchronous transactions but without implementing some kind of metering you could easily flood your system and bring it down.

Hi Christian,

For another company we implemented categories for high priority messages and lower priority message. That is something we can also do now.

I will try and find the notes you are talking about.

Peter,

Here is the note for the parallel processing:

If you search notes with MII and Message Listener you should be able to easily find the other performance tuning notes.

Good Luck!
