Getting DPR-ERR-2056 while running a RI report with the option of Run with .csv format

1
Dhanya Saseendran (88●2●11●21) | asked Jan 10 '14, 3:05 a.m.
 Hi,

I am getting an error when I run the RI report with the format as .csv or excel. But it runs fine with the HTML format. I require a .csv format or an excel version to learn and correct my reports. Can anyone help?

The error details are as below.

DPR-ERR-2056 The Report Server is not responding. Handler trace back: [the_dispatcher] com.cognos.pogo.handlers.performance.PerformanceIndicationHandler [the_dispatcher] com.cognos.pogo.handlers.logic.ChainHandler [service_lookup] com.cognos.pogo.handlers.engine.ServiceLookupHandler [load_balancer] com.cognos.pogo.handlers.logic.ChainHandler [lb_forwarder] com.cognos.p2plb.clerver.LoadBalanceHandler [batchreportservicechain] com.cognos.pogo.handlers.logic.ChainHandler [warptask_with_authenticate] com.cognos.pogo.handlers.logic.ChainHandler [do_batch_warp] com.cognos.pogo.handlers.logic.ChainHandler [warptaskmtaChain] com.cognos.pogo.handlers.logic.ChainHandler [warptaskmta] com.cognos.pogo.reportservice.BatchReportServerHandler

Thanks
Dhanya

Hello Dhanya,

a difference between generating a report as HTML and generating it as csv or excel is that in HTML the report server generates a page at time while in csv/excel the report server generate the whole report at once.
A report returning a very large data set or requirning complex computation might work well in HTML but timeout in csv/excel

Hi Fransesco,


Thank you for your response. I will try to improve the performance of the report. 
I had seen a link on improving the performance of RI reports but not able to find it now. Could you please give me if you have it?

Thanks

Hello Dhanya,

I would start from this topic of the Cognos info center:

Report Runs Slowly
