SOAP adapter time out issue

Dear friends,

I have a SOAP-PI-Proxy scenario and publish the service interface as a web service, unfortunately the inbound ABAP codes may need about 3 minutes, when I test the scenario with client codes or XMLSpy tool, we both get the time out issue.

From my understanding, this problem may happen in the following 2 phases:

1. from client to adapter engine (Java engine)

2. from adapter engine to integration engine via ICM service

Firstly I checked the log of the adapter engine and found that the time out happens after 1 minute after setting up the connection between adapter engine and integration engine (http://host:icmport/xi/engine.....), after some investigation it's because of the ICM processing time out limitation (60 seconds by default), therefore I changed the value from 60 seconds to 300 seconds, there is no error in the adapter engine.

But we still get the time out issue from the client side, I guess there also has the problem in the phase 1, it's due to some Java engine connection or processing time out settings, could anybody tell me which parameters should I change?

Any advice will be very appreciated.

Thanks and regards,

Bean
