Slow Processing of Messages in Adapter Engine

[Former Member]

Hi,

I have an SAP Outbound Scenario, which has an Asynchronous Scenario. ABAP Proxy > PI > SOAP

In a specific interface we have approximately 5000 messages being processed.

Yesterday, there are messages that were processed during the morning but the messages are still being processed upto today. We also have messages for today and it is still in queue.

I have checked the RWB> Component Monitoring > Adapter Engine > Engine Status

In the Backlog tab, there are a lot of Error Backlog and Processing Backlog. In the Additional Data tab, the SOAP_http://sap.com/xi/XI/SystemRecv has 650 messages in queue - 3/3 Threads - 5 Max No of Threads.

Why is it taking so long to process the messages? Is it because of the voluminous data?

Specs: SAP PI 7.1 SP 08

thank you.

Hi Chrizel,

It's taking any particular timing or the whole processing t of this interface is slow.  it's may be huge messages triggered at that time or high volume.

Thanks,

Seshu.

Hi Chrizel -

Are those messages huge in size? which step is taking much time?

If it is in integration engine - please check which pipeline step is taking much time..

If it is in adapter engine,  you can increase the number of threads in messaging system if your web service can handle further load..

Refer to section 6.1 in the below document -

Hi Hareesh,

I noticed that the it takes 2-4 minutes in the SOAP: request message entering the adapter with user J2EE_GUEST before it is SOAP: completed the processing

here is the Audit Logs:

2014-03-31 01:05:28	Information	The message was successfully retrieved from the receive queue.
2014-03-31 01:05:28	Information	The message status was set to DLNG.
2014-03-31 01:05:28	Information	Delivering to channel: CC_SalesDeliveryOrder_SOAP_Rec
2014-03-31 01:05:28	Information	SOAP: request message entering the adapter with user J2EE_GUEST

2014-03-31 01:09:43	Information	SOAP: sent a delivery ack
2014-03-31 01:09:43	Information	The message was successfully delivered to the application using connection SOAP_http://sap.com/xi/XI/System.
2014-03-31 01:09:43	Information	The message status was set to DLVD.

Which one should I adjust?

thank you.

Hi Chrizel - Though it could be because of high volume, You can try increasing the threads for Soap Adapter as explained in the below blog under " Configure consumer threads per adapter"

If possible replicate the same load in test environment by changing the configuration and see if there is any improvement..

Hi Chrizel

I suggest that you also check the the receiving application to see if the bottleneck is on their side - limited resources, limited number of parallel access.

If the bottleneck is on their side, increasing the number of threads may overwhelm the receiving application.
