To access databases controlled by a FOCUS Database Server you must allocate a communication data set before entering SU. For information about allocating the communication data set on the server and on the client, see Starting a FOCUS Database Server and Using Centrally Controlled Databases.

Note that you refer to an individual FOCUS Database Server (for example, in the SINKID parameter of the FCB and in the ? SU query) by the ddname to which you allocated its communication data set.

Do not allocate the centrally controlled databases. Allocate all other files as you would if running HLI programs to read and modify local databases. (Note: HLI users wishing to use other databases locally must remember to allocate them with DISP=OLD).
