Cognos Error - DPR-ERR-2056: Report server is not responding

[ordotan]

Hi,

I'm getting this error when testing my data source (Oracle) :

DPR-ERR-2056: Report server is not responding
Handler trace back: [the_dispatcher]
com.cognos.pogo.handlers.performance.PerformanceIndicationHandle
r [the_dispatcher] com.cognos.pogo.handlers.logic.ChainHandler

com.cognos.pogo.handlers.logic.ChainHandler [do_warp]
com.cognos.pogo.handlers.logic.ChainHandler [warpmta]
com.cognos.pogo.reportservice.ReportServerHandler

Cognos and Oracle are on seperate servers, but I can open sqlplus from the cognos server to oracle server, so it's not a DB issue.

When I open Cognos Configuration, all the components are tested successfully.
I have tried defining the data source from scrach, restarting Cognos service, and even restrting the entire server.. but without luck.

I have read some IBM references to this error, but none of them gave me the solution.

Do you have any recommandation ?
