The dbspace name, an internal name for the dbspace, must be unique in a database and across a multiplex. Dbspace names are case sensitive for databases created with CASE RESPECT. (To view the CaseSensitive setting, right-click the database, choose Properties, and view the Extended Information tab.) Type the name for your new dbspace in the first text box.
Now specify a store for the dbspace:
On a write server, the wizard creates a dbspace in the Main IQ Store (Alt+M) by default. If you prefer the Temporary IQ Store, click the Temporary IQ Store option (Alt+T).
On a query server, the wizard creates a dbspace in the Temporary IQ Store (Alt+T) by default. To create a Local IQ Store, click the Local IQ Store option (Alt+L). Changes to the data in a local store are local to the query server, allowing users to continue development operations on that query server without affecting the shared main storage.
