DPR-ERR-2002 Unable to Execute the Request

Hi Cognos Gurus

I have an installation of Cognos 10.1.1 Service Pack 3 on a Virtual Machin, and I get this error when I test my Data Source Connections and Dynamic Query Mode is enabled. I tried all the solution that I founde in the Internet but no one worked successfully

I would like to know what am I doing wrong?.. or if my problem resides because my VM doesn’t have enough Memory…

Please I need some tips about this.

Thanks in advance.

Have you copied the ojdbc5.jar/ojdbc6.jar/ojadbc14.jar file to /v5dataserver/lib location???
