Is there a limit on the number of results (requirements) that can be fetched from RRC?

I have about 750 to 800 requirements in my project in Rational requirements Composer. I am trying to upload test cases for these requirements in Rational Quality manager (RQM) using the RQMWordExceImporter utility.
While doing the upload, I try to link the test cases to existing requirements which are fetched from RRC.
This requirements fetch works fine for lesser number of requirements example: around 300-400.
But when the number of requirements increases (to the order of 500s and 600s), i start seeing the following error:
Is there any limit on RRC, for the number of requirements that can be fetched by the client. In this case, the RQMExcelWordImporter Utility?
Is there any configuration setting that can be modified to return all the requirements from RRC?
Please advice!!

It has been identified that this is a limitation of RM OSLC REST API as
there is, in fact, no timeout option provided by the RM server when querying the requirement url. An enhancement request has been submitted to use pagination: https://jazz.net/jazz02/web/projects/Rational%20Quality%20Manager#action=com.ibm.team.workitem.viewWorkItem&id=88033 |
Hi Vijay,
I'm not aware of such limit. I presume you're using CLM 4.0.1 : Could you share the RQMExcelWordImporter logs ? See https://jazz.net/wiki/bin/view/Main/RQMExcelWordImporter#Troubleshooting for details on where it's located. Regards, Stéphane Comments @Stephane Leroy....
I will paste the entries from the Mso2Rqm_Debug.log in my next answer below. I see the follwoing "Operation Timed out" error at the end:
4/8/2013 10:51:52 AM: INFO: <Unknown Caller Context>: response from project has response content key 4/8/2013 10:51:52 AM: INFO: <Unknown Caller Context>: response has keys: System.Collections.Hashtable+HashtableEnumerator 4/8/2013 10:54:04 AM: ERROR: <Unknown Caller Context>: Exception when get from RM server: The operation has timed out
I have about 793 Requirements on RRC for my project. This same procedure using the Utility works when I have less number of requirements (less than 475 or 500). But when the number of requirements increases, the upload fails consistently and I get the "Operation timed out" error in the debug log and the error as shown above in the screen shot.
Is there any way to turn on Debugging on the utility side? Or is there any other config setting I need to check on RRC side?
Please advice.
Thanks,
Vijay.S

Hi Stephane,
We increased the SPARQL Query Abort Timeout to 10 minutes and re-ran the tests. With more number of requirements (>500) on RRC, we still get the "Exception when get from RM server" error.
And, regarding the environment, Yes the Jazz applications are hosted on Virtual Servers.
One other observation when I ran the tests today is mentioned below.
In all the cases (successful/failed tests), the test runs do not take more than 5 minutes. Usually it takes around 3.5 to 4 minutes to complete the "full test run". A "full test run" consists of the following events/steps:
1.Open the MS-Excel Spread Sheet containing the Test cases.
2.Click on the RQM Add-ins in the excel sheet and enter the Credentials. Then, click on "Validate".
3.Available projects get populated in the "Project" drop down list. It takes approximately 15-30 seconds for the project list to get populated.
4.Select the Project from the drop down list, check "Link to Existing Requirement" and click on "Export".
5.In the next dialog box, select the RM project, enter the credentials and then click on "Export".
6.The Utility starts to fetch the Requirements from RRC, once "Export" is clicked.
7.From this point, it takes about 100 seconds (1 minute and 40 seconds) for the utility to:
either return all the requirements and display it in the right pane
or report the "Exception when get from RM server" error.
From this time line, I believe the utility takes about 100 seconds to fetch the requirements from RRC and succeed/fail. I tried multiple tests with these requirements and found this 100 second timeline to be consistent. The log entries from the Mso2Rqm_Debug.log, where these events listed above take place are as shown below:
