Hello Experts,
We have 1 time-critical real-time interface, for which the processing needs to be completed within 15 seconds. If the response is not received within 15 seconds, then the process times out on the source system.
Source <--> SOAP sender (sync) <--> SAP PI <--> JDBC receiver (sync) <--> Target
The interface usually completes the processing within 2-3 seconds. But there are instances where the the user has reported time-outs and when we check the audit logs, it clearly indicates a processing lag within SAP PI system itself.
Below is the audit log information for one of the transaction that timed-out (meaning which took more than 15 seconds end to end)
27.06.2013 10:37:41.571 Information SOAP: request message leaving the adapter (call)
27.06.2013 10:37:41.571 Information The application tries to send an XI message synchronously using connection SOAP_http://sap.com/xi/XI/System.

27.06.2013 10:37:57.969 Information SOAP: call completed
27.06.2013 10:37:57.970 Information SOAP: completed the processing
27.06.2013 10:37:57.971 Information The message was successfully transmitted to endpoint http://xxxx:port/sap/xi/engine?type=entry using connection SOAP_http://sap.com/xi/XI/System.
27.06.2013 10:37:57.971 Information The message status was set to DLVD
I am just confused on how to troubleshoot this issue. From the logs, it looks like messaging system is taking more time.
Is there any particular reason why the PI processing takes more time between those highlighted steps?
If you could point me to some of the areas where I need to look at to find out the root cause, that will be really appreciated.
