Regarding Connection Time Out issue in Webservice call to database.

Question

Hi,
We are facing one issue with the webservices call to DB and ILOG. We are declaring and executing the webservice in the following way-
//Request Object
EDP.ILog.PEWM_EXPDOC_Help_Information_ProxyService.DecisionServiceRequest helpRequest = EDP.ILog.PEWM_EXPDOC_Help_Information_ProxyService.DecisionServiceRequest();
//Response Object
EDP.ILog.PEWM_EXPDOC_Help_Information_ProxyService.DecisionServiceResponse helpResponse = EDP.ILog.PEWM_EXPDOC_Help_Information_ProxyService.DecisionServiceResponse();
//Proxy Service Object Initialisation
DecisionServicePEWM_EXPDOC_Help_InformationService helpService = DecisionServicePEWM_EXPDOC_Help_InformationService();
helpService.executeDecisionService(parameters : helpRequest, out parametersOutput : helpResponse);
All the webservices are configured corectly in External Resources of Process Administrator. Now, the issue is that whenever we are trying to execute the service with good amount of load on OBPM Process Admin Engine, it is throwing the following exception-
"Exception:java.net.ConnectException: Connection timed out: connect"
We are unable to find the root cause of the issue as the webservices call is still throwing the above exception.
Please provide some resolution as soon as possible.
Thanks in advance,
Abhishek

Just to be sure, we're talking about a client process in BPM accessing an ILOG web service or a DB web service, right? Is this DB web service something custom built?
Be aware that certain things can run inside the workspace and not the engine. You almost have to work at making this happen. The easiest way is to make this happen is to invoke a BPM object method from within a BPM object presentation or JSP. If you do have this situation open the BPM object method and click on properties and check the box run on server side.
I can't think of anything that wouldn't scale for connections to Web Services in an engine. I'd be looking at tuning your ILog Web services. Perhaps it can't keep up and the engine gets a timeout. How often does this happen? The engine should retry the automatic until is works. But it tries 3 or so times, it gives up. This retry is configurable.
