Uncertain about double sRFC call in Audit Log

[JaySchwendemann]

Dear all,

we have a SOAP -> PI -> RFC scenario (synchronous so back would be RFC --> PI --> SOAP).

When looking into the audit log of the request (SOAP --> PI --> RFC) message from runtime workbench message monitoring (adapter engine) i get the following output:

21.03.2012 11:42:09.453	Success	Message successfully received by messaging system. Profile: XI URL: http://<hostname>:50000/MessagingSystem/receive/AFW/XI Credential (User): <user>
21.03.2012 11:42:09.456	Success	Using connection RFC_http://sap.com/xi/XI/System. Trying to put the message into the request queue.
21.03.2012 11:42:09.457	Success	Message successfully put into the queue.
21.03.2012 11:42:09.457	Success	The message was successfully retrieved from the request queue.
21.03.2012 11:42:09.457	Success	The message status set to DLNG.

21.03.2012 11:42:09.460	Success	RFC adapter received a synchronous message. Attempting to send sRFC for Z_HYB_GET_MATAVAIL
21.03.2012 11:42:09.460	Success	RFC adapter received a synchronous message. Attempting to send sRFC for J2EE_GUEST
21.03.2012 11:42:09.603	Success	MP: Leaving module processor
21.03.2012 11:42:09.609	Success	The message was successfully delivered to the application using connection RFC_http://sap.com/xi/XI/System.
21.03.2012 11:42:09.610	Success	The message status set to DLVD.

I'm quite uncertain about the line that states "RFC adapter received a synchronous message. Attempting to send sRFC for J2EE_GUEST". The line above stating "RFC adapter received a synchronous message. Attempting to send sRFC for Z_HYB_GET_MATAVAIL" holds the RFC "Z_HYB_GET_MATAVAIL" that we are calling.

1. What is J2EE_GUEST doing here? Do we have a misconfiguration at some point?

2. As you can see I have 140ms Delay from the line "RFC adapter received a synchronous message. Attempting to send sRFC for J2EE_GUEST" to the line "MP: Leaving module processor". I already read the PI performance guide but didn't get any hints on this delay. Is this the normal processing time of the RFC?

Thanks and kind regards

Jens

Is the RFC adapter Load balanced?

This usually arises when the end system is under load and doesnt have the required resources to process the request from PI.

[JaySchwendemann]

I had a look at the receiver communication channel "CC_RFC_RCV_ERP_EN". The checkbox "load-balancing" is not set. Did you mean that by "is the RFC adapter load balanced"? If not, how would I check this?

Cheers
