Configuring the DataServer Configuring a remote DataServer 5–6 In configurations that include a remote host, two DataServer processes run on the host machine: • Broker — The DataServer broker (_probrkr.exe) or the broker for the Progress Explorer on the host machine determines the types of requests coming over the network and starts (spawns) the appropriate DataServer (_msssrv.exe) for the client process. • DataServer — The DataServer (_msssrv.exe) on the host machine accesses the MS SQL Server database and communicates with the client process. Note: The OpenEdge MS SQL Server DataServer component is an ODBC client with respect to the MS SQL Server database configuration even though from the OpenEdge point-of-view it resides on the server machine. As a result, your MS SQL Server client software must reside on the machine from which the DataServer and the broker processes will execute. In the remote DataServer configuration, the OpenEdge client component requires no special software or configuration; it only requires a standalone OpenEdge Windows or UNIX client. There are no OpenEdge restrictions regarding the location of the actual MS SQL Server database. Before you can run the server components, you must configure the DataServer by setting the required environment variables on the host machine. In Windows, you configure the DataServer using the Progress Explorer tool. See the “Configuring with the OpenEdge Explorer and Progress Explorer” section on page 5–6 for details. Configuring with the OpenEdge Explorer and Progress Explorer In Windows, you can use the Progress Explorer tool to configure the DataServer for MS SQL Server. Note: This section primarily focuses on how to access the Progress Explorer to configure the DataServer for MS SQL Server in Windows. It briefly presents a few examples about how to connect the DataServer. However, for more complete connection instructions, see the “Starting and stopping a broker process from the OpenEdge Explorer and Progress Explorer and connecting a client” section on page 6–3. For information about the Progress Explorer, see the Progress Explorer online help. To access the Progress Explorer in Windows: 1. Make sure that the AdminService is running. 2. Start the Progress Explorer. Choose Start→ All Programs→ OpenEdge→ Progress Explorer Tool. 3. Connect to localhost. 4. From the Progress Explorer’s left pane, select the MSS DataServer folder and double-click. The list of existing DataServer brokers for MS SQL Server appears in the right pane.
Configuring a remote DataServer 5. Select the DataServer instance whose properties you want to create or edit, and right-click. A pop-up menu appears. Note: The DataServer for MS SQL Server installation provides one predefined DataServer Broker (mssbroker1) and one predefined NameServer (NS1). (The NameServer is located in the NameServer folder.) Each broker is referred to as an instance. See the Progress Explorer online help for more information. You can use these predefined components as a starting point for creating and configuring additional DataServer Brokers, and, if needed, NameServers. (See OpenEdge Getting Started: Installation and Configuration for information about the NameServer’s role in a configuration.) 6. Choose the Properties option from the pop-up menu. The Properties dialog box for that instance appears. 7. Configure the DataServer broker by setting general DataServer properties, owner information properties, application service properties, logging settings, environment variables, and others. For details on these settings, see the Progress Explorer online help. Proceed to Step a to use the DataServer for MS SQL Server broker instance with a controlling NameServer (as provided by a default Data Service). Otherwise, proceed to Step b to use the broker instances or without the NameServer (using the -DirectConnect parameter option): a. To use the controlling NameServer to manage your broker instances, use the Data Service (This is the default and recommended option. For syntax and examples, see the “Connecting to a MS SQL Server DataServer broker using the NameServer” section on page 5–7.) As a result, the DataServer client’s initial connection is to the NameServer. b. To connect the DataServer directly to the broker instance, do one of the following: • Set the -DataService value to none in the connection parameters of your schema holder. If you plan to always use a -DataService value of none, remove the controlling NameServer from your broker instance definition. • Add the -DirectConnect parameter to override your -DataService parameter. See the “Starting and stopping a broker process from the OpenEdge Explorer and Progress Explorer and connecting a client” section on page 6–3 for more information about connecting the DataServer to the NameServer and the broker. Connecting to a MS SQL Server DataServer broker using the NameServer This section presents an example of how to connect to a MS SQL Server DataServer using the NameServer. To connect to a MS SQL Server DataServer using the NameServer: 1. Create a schema holder. 5–7
