Request timed out because there has been no reply from the server in 600000

Question

Issue:
Request timed out because there has been no reply from the server in 600000
Scenario:
1. All the crystal reports are designed by using Crystal Report 2008 Version -- 12.3.0.601
2. All reports are uploaded to CMC (SAP Business Objects Enterprise XI, Product: 12.1.0)
3. using Front-End .net Winform
4. Crystal Report is binding is done using Business View Manager (since having more than one databases)
5. Business View Manager Connects to Oracle using "Oracle Server" connection
6. Loading reports as follows
string queryString = string.Empty;
SessionMgr sessionMgr = new SessionMgr();
EnterpriseSession enterpriseSession = sessionMgr.Logon(userName, userPassword, serverName, authType);
EnterpriseService enterpriseService = enterpriseSession.GetService("InfoStore");
InfoStore infoStore = new InfoStore(enterpriseService);
enterpriseService = enterpriseSession.GetService("PSReportFactory");
Object psrfObject = enterpriseService.Interface;
PSReportFactory psReportFactory = (PSReportFactory)psrfObject;
queryString = "Select SI_CUID, SI_ID, SI_NAME, SI_PARENTID From CI_INFOOBJECTS " + "Where SI_PROGID='CrystalEnterprise.Report' " + "And SI_ID=" + ReportId;
InfoObjects infoObjects = infoStore.Query(queryString);
InfoObject infoObject = infoObjects[1];
ReportDocument crDoc = new ReportDocument();
crDoc.Load(infoObject, enterpriseSession);
7. All the reports are getting loaded properly and i am able to dynamically set the report parameters
8. After executing report, some of the reports take more than 10 minutes, due to which shows following error
Request timed out because there has been no reply from the server in 600000
Note i have done following:
1. I have checked stored procedure running through oracle for more than 10 minutes (1 hr, 2 hrs)
2. Tried simply running crystal report without front-end running perfectly more than 10 minutes (1 hr, 2 hr)
3. When i run .net winform application for specific reports which takes long time, gives "Request timed out because there has been no reply from the server in 600000"
Also i have done lot much R&D and spent almost weeks to get resolution but not getting any solution out of it, please help me in this case

Answer 1

This error is specific to RAS. The default CORBA request timeout is 10 minute = 600000 ms. When the RAS SDK does not get the reponse back from RAS server in 600000 ms it throws this message. Why it works in InfoView\CMC what I believe you refer to as "Front End' application is because InfoView\ CMC don't use RAS.
1. First make sure that a smaller report wich runs pretty fast ( 1-2 min) works. This will confirm that there is no connectivitiy issues between RAS and RAS SDK.
2. If you get the efrror for every single report, even the smaller ones, make sure the box running RAS and RAS SDK code( in case they are 2 different) can ping each other with IP, shortname and FQDN. If there is a firewall between them, the RAS port needs to be opened for bidirectional communication. By default RAS chooses a random port for communication with SDK but within CMC you can configure it to use a specific port and open it.
3. If the issue is specific only to reports that are long running, typically more than 10 minutes, then you need to inclease the CORBA timeout to a value more than what the reports typically would take to process. This is done on client code side or IIS in this case.
Here are the steps:
Make the following changes on the application server/system.
Open RegEdit by going to Start > Run and typing in regedit.exe. Then click Ok.
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Report Application Server\Client SDK\CorbaAdapter
Change the value of SendRequestTimeout(ms) to 100000.
Change the value of WaitReplyTimeout(ms) to 6,000,000 ms. The default value is 600,000 ms and may not be long enough.
Restart IIS by going to Start > Run and typing in iisreset. Then click Ok.
Retry the failing application.

This error should be easy to fix
