Messaging Queues

[Former Member]

Can someone please explain me what kinds of Queues does IDOC, RFC,Proxy, SOAP, File message processing use?

like, I have many scenarios where in I am sending data to IDOC, RFC, Proxy, SOAP and file adapters. Which Queue is used in each case?

or is it that only one Queue is used to carry all kinds?

Next question is: If I have few proxy message stuck in Queue does it allow smooth processing of RFC messages or IDOCs?

Q: If some RFC messages (Eg; Bapi_po_Create) are stuck in Queue, does it allow processing of a different BAPI (BAPI_po_change) while bapi_po_create stuck in Queue?

Q : If some RFC messages are stuck in Queues and does it allow proxy messages to process?

I did search in SDN before posting this question, I did not get exact answers...

Thanks,

Venkat..

If the QoS is EOIO then a dedicated queue is used for message processing....also one (or specified) queue will be used if you configure message/ queue prioritization for your interface.

In other cases, the queue is determined at runtime....its not just one queue that is used.

Next question is: If I have few proxy message stuck in Queue does it allow smooth processing of RFC messages or IDOCs?

It would.

A good blog on queue .... incase if you have not checked it already : /people/sap.india5/blog/2006/01/03/xi-asynchronous-message-processing-understanding-xi-queues-part-i

Hi Venkat,

There are build in queues to more refer the help link

http://help.sap.com/saphelp_nw04/helpdata/EN/04/827440c36ed562e10000000a155106/content.htm

As mentioned above queues are mostly inbuilt functionality in XI message processing,but there are some

specific queues and Queues can be prioritized by doing the necessary configuration in admin.

here are some pointers which would give you some insight.

we can't say exactly, depending on the messages XI automatically creates the number of queues.

According to my knowledge, if one queue messages are strucked then other queue messages goes as it is.
