As previously mentioned, Engines usually run on a different platform than the Data Capture Agent. The Controller Daemon on the Capture platform manages secure communication between Engines and their Capture/Publisher Agents. Therefore a Public / Private Key pair must be generated for the Engine on the platform where the Engine is run. The SQDutil program must be used to generate the necessary keys and must be run under the user-id that will be used by the Engine. For more information about this utility, see the Connect CDC (SQData) SQDUTIL.
Syntax
$ sqdutilkeygen
On z/OS, JCL similar to the sample member NACLKEYS included in the distribution executes the SQDutil program using the keygen command and generates the key pair.
The Public key must then be provided to the administrator of the Capture platform so that it can be added to the nacl.auth.keys file used by the Controller Daemon.
