Sync messages should have higher prioritization in IE than async messages.

[Former Member]

Hi Guys,

I got the same issue as mentioned in the below thread. Message prioritization in SXMB_ADMIN does not work because it's ony applicable for async (EO / EOIO) messages.

Is there any setting do we need to do to give high priority to Sync messages. I want sync messages to process ASAP.

Thanks

Deepthi.

Synchronous messages are by default high priority as the the calling systems are waiting on the calls. Also, they are processed immediately as they receive since the queuing logic is only applicable to asynchronous message processing.

On IE you can increase further the priority of the synchronous queues (by increasing max Runtime, for example), using the QIN scheduler (SMQR). Please check the help page and the note below for more information

Hi Deepthi,

In response to your following mail:

Hi Gourav,
I saw one of the thread which you mentioned that sync messages doesn't required any priortization as by default it possess high protiry in IE. Can you please elaborate and confirm about it in the below thread.
Thank you for your time.

I can only say that what I said in previos thread:

 Sync messages always have higher priority and I guess this logic is built-in within IE so if many messages arrived at the same time sync message will be processed first by IE.
However I am not aware if any config parameter exist to assign/change priority of sync message. I guess it is implied. 

However in some extreme cases I recommended dual installation of PI for sync/async messages because async message consume all the resource of system resulting failure of sync messages (XI 3.0 based scenarios). You can also considering installing additional decentral adapter engine to reduce load on PI system (if it is PI 7,1 system then try to configure "Integrated scenario" wherever possible")
