Chapter 5: Configuring the DataServer Permissions for connecting a schema holder When you connect to a schema holder, you can also choose to connect to your MS SQL Server database. To connect to the data source, you must provide a valid login name and password combination. Use the User ID (-U) parameter to provide the user ID and the Password (-P) parameter to provide the password. Figure 8 shows an example of the User ID and Password dialog box. Figure 8: User ID and Password dialog box Note that value xxxxxx that appears in Figure 8 is only a placeholder for the actual MS SQL Server database name to which you intend to connect. Application-specific permissions In addition to the MS SQL Server database permissions required by the DataServer, the required permissions for users depend on the applications that they are using. For example, a user who is running an OpenEdge application that queries but does not update the employee table in the data source must connect to the data source with a login name and password combination that provides at least SELECT privileges for the employee table. For users who will manipulate data at runtime, the appropriate select, insert, update, and delete permissions must be granted as administered by the foreign (target) data source. In summary, the login name (or user ID) and password combination required to run a particular application depends on the following: • The tables that the application accesses • The type of access required to those tables Preparing to create the schema holder This section addresses the steps required to create the schema holder. To prepare to create the schema holder: 1. Verify that your MS SQL Server database is accessible and that you can connect to it. Transact-SQL and the MS SQL Server Query Analyzer can serve as a test for connectivity. 2. Verify that you have installed the ODBC drivers. 3. Once you have configured your data source (DSN), make sure that you can establish a connection independent of using the DataServer. From your DSN 198 OpenEdge Data Management: DataServer for Microsoft SQL Server
Creating a schema holder configuration, select to test the connection to MS SQL Server using the ODBC interface. 4. Start the DataServer as described in either the “Starting a local DataServer” section on page 210 or the “Starting a remote DataServer” section on page 211. 5. Open the Data Administration or the character Data Dictionary. Creating a new empty OpenEdge database The DataServer uses the empty OpenEdge database as a holder for the schema for your MS SQL Server database. The simplest way to create an empty OpenEdge database is to do it from the Data Administration, as described in this section. For information on other ways to create an empty OpenEdge database, see OpenEdge Data Management: Database Administration. If you create a new OpenEdge application to be Unicode-enabled, ensure that you create the database from a Unicode source. A copy of the empty OpenEdge UTF-8 database can be obtained from $DLC/prolang/utf/empty. If you choose UTF-8 as your schema image code page, your schema holder’s code page must also be UTF-8. If you create a new OpenEdge application to be Unicode-enabled, ensure that you create the database from a Unicode source. A copy of the empty OpenEdge UTF-8 database can be obtained from $DLC/prolang/utf/empty. If you choose UTF-8 as your schema image code page, your schema holder’s code page must also be UTF-8. To create and connect an empty OpenEdge database from the OpenEdge Data Administration tool: 1. Start the Data Administration. 2. Select the Database→ Create option. The Create Database dialog box appears: 3. Type the schema-holder name (for example, mssholder) in the New Physical Database Name field. 4. Select the An EMPTY Database option.
