Configuring the DataServer Maintaining a schema holder 5–22 The Data Administration provides a set of DataServer utilities that you can use to maintain a schema holder. Chapter 7, “The DataServer Tutorial,” describes these utilities. Note: Keep in mind that you must have SELECT privileges on certain data source objects to update a schema holder. See the “Permission requirements” section on page 5–15 for details. If you make changes to a MS SQL Server database, make sure to update the associated schema holder to reflect those changes if you want them to be accessible to a DataServer application. Note that you do not need to update the schema holder if the application will never access data objects affected by the change. For example, if you add a table object that a DataServer application will never access, you do not need to update the schema holder. Each time that you update the schema holder, you must recompile your DataServer application (.p and .w files) to generate new r-code. Updating a deployed schema holder The guidelines and techniques that apply to deploying an OpenEdge database also apply to deploying a schema holder for a MS SQL Server database. However, if you make any changes to the data source schema, make sure to update its schema holder. There are two techniques for updating a deployed schema holder: • Allow your users to use the DataServer Update/Add Table Definitions utility. • Send a new data definition file for the schema holder. Your users can use the DataServer Delete Schema utility to empty the original schema holder. They can then load the new data-definition file into the schema holder. To update a deployed DataServer application: 1. Run an SQL script to make changes to the MS SQL Server database. 2. Run the Update/Add Table Definitions utility on one schema holder. 3. Recompile code against the updated schema holder to build new r-code. 4. Send out copies of the new .r files to your users. 5. Distribute copies of the new schema holder .db and .bi files to your users. You must use the PROCOPY utility to distribute them.
Typical configuration for a remote client to connect to a remote DataServer Typical configuration for a remote client to connect to a remote DataServer A typical configuration to connect a remote client to a remote DataServer requires the following general tasks: • Configuring an ODBC data source • Starting a broker • Starting the schema holder to accept remote client connections • Connecting remote clients to the MS SQL Server DataServer broker This section highlights the basic procedure associated with each of these tasks. Configuring an ODBC data source An ODBC data source allows you to store information about how to connect to a data provider. You use the ODBC Data Source Administrator to configure an ODBC source. Note that the DataServer license must be installed on the machine where the ODBC data source is configured. To configure an ODBC data source: 1. In Windows, choose Start→ Control Panel→ Administrative Tools→ Data sources (ODBC) and select Systems DSN. The System DSN Data Source Administrator appears. 2. Choose Add to add a data source with either the MS SQL Server driver or an OpenEdge branded ODBC Wire Protocol driver for MS SQL Server. Proceed through the windows as they are presented to configure the data source, ensuring that the final test connection is successful. Starting a broker You can start the DataServer broker, using various methods supported by the Unified Broker Framework, including: • The OpenEdge Explorer and Progress Explorer tool or mergeprop utility (for a Unified Broker) • The command line (for a probroker) The following example shows how to perform this step from the command line. For information about using the mergeprop utility, see OpenEdge Getting Started: Installation and Configuration. For information about using the OpenEdge Explorer and Progress Explorer tool, see the “Starting and stopping a broker process from the OpenEdge Explorer and Progress Explorer and connecting a client” section on page 6–3, and see OpenEdge Getting Started: Installation and Configuration. 5–23
