PI Messaging Queues: Registration & Prioritization

[Former Member]

Hi! Gurus

I am trying to understand and learn the concept how Messaging Queues are Configured & Registered and also how can Prioritize Queues for specific Critical interfaces on the projects.

I have tried to read through various posts - however, still need help with the below questions:

1. How & where (transactions) does Basis configure / register Queues apart from SMQR?!

2. Wat is the criteria for creating the no.of Queues - Are they standard set of default no. of queues during PI installation - OR - are no. of Queues configured different on a PROD PI Server based on volume?!

3. How different are EO Queues from the EOIO Queues - and wat is the criteria for messages to be routed from EO or EOIO Queues?!

4. How can we prioritize queues ?! - Can we create separate Queues for specific interfaces -OR- We have to use existing Queues and filter based on  Sender/Receiver interface - wat is the transaction to configure the Priority Queues / Messages.

5. Is the Queue Prioritization available only on the ABAP Stack only - are they any message prioritization for Adapter Engine / JAVA Stack available?!

6. Finally is there a specific no.of messages the Queues are configured to hold?!

I am hoping to gain some knowledge with regard to Message Queue Registration Prioritization through the above questions - sorry for putting forth so many questions - Thank you for your help & patience in reading through this discussion ...

Thank you,

Hello,

1. How & where (transactions) does Basis configure / register Queues apart from SMQR?!

>>SXMB_ADM -> Manage Queues -> Register/Deregister

2. Wat is the criteria for creating the no.of Queues - Are they standard set of default no. of queues

during PI installation - OR - are no. of Queues configured different on a PROD PI Server based on volume?!

>>There are default set of queues for inbound/outbound/ack in PI.

3. How different are EO Queues from the EOIO Queues - and what is the criteria for messages to be routed from EO or EOIO Queues?!

>>Async messages at runtime are processed in a queue from integration engine, so if there is a requirement to process message in a sequence like first in first out then we have to use  EOIO queues to achieve the same.However if the sequence is not important then messages are processed using a EO queue (by default).

4. How can we prioritize queues ?! - Can we create separate Queues for specific interfaces -OR- We have to use existing Queues and filter based on  Sender/Receiver interface - wat is the transaction to configure the Priority Queues / Messages.

>>Search SDN, there are lot of articles for the same.

5. Is the Queue Prioritization available only on the ABAP Stack only - are they any message prioritization for Adapter Engine / JAVA Stack available?!

>>No, u can prioritize messages both at AE and ABAP level

PI7.1

PI7.3 (Java)

6. Finally is there a specific no.of messages the Queues are configured to hold?!

>>No, i don't think so.

Hi! Gurus

Is it a good practice to Prioritize EOIO Queues.

Please, let me know your thoughts?!

Hello,

First  question needs to be answered is do u really need EOIO queues?

In terms of prioritizing EOIO queues, I haven't seen such kind of requirement anywhere but I don't see much issues in doing that but having said so, u have to be extra vigilant in checking if messages are processing successfully through that prioritized EOIO queues or not.

Thanks

Hi Ritu,

Adding to Amit's reply. EOIO is used to serialize the messages. Please check the below blogs which would be useful
