This parameter determines how and where authentication of a user takes place. If authentication is SERVER, then the user id and password are sent from the client to the server so authentication can take place on the server. A value of CLIENT indicates that all authentication takes place at the client, so no authentication needs to be performed at the server. For a client-only node, CLIENT, SERVER, and DCS are effectively the same. A value of DCE means that authentication is performed using DCE Security Services. If you are using APPC and a communications product that does not expose the client's password to the DB2 server, you can specify DCS to obtain:
The following show the API constants to use for possible values for this parameter:
