Cognos Audit Extension Console Connection Error

[bi4business]

Hi All,

Does someone has installed the Audit Extention Module within Cognos Analytics ?

I installed all software and followed the installation steps but I get still a connection error trying to connect to the Audit Extention DB within my environment.

Using Cognos Configuration and test connecting to my Audit Extention DB I get a success.
But when do the same within the Extention Console, I get an error:

"Error: ERROR - Unable to connect to database - check the settings are correct."

What should I do ?
What *.LOG file can I use ?
