Specifies the full path name of the file that contains the pre-generated Diffie-Hellman 2048 bit key.
Parameter type: optional, static
The generation of Diffie-Hellman parameters can be computationally very expensive. To minimize this cost, the Diffie-Hellman 2048 bit key can be pre-generated and stored in a file that is called when the IBM® Cognos® TM1® server starts.
