Configuring with the Progress Explorer

On NT, you can use the Progress Explorer tool to configure the DataServer for ODBC.

NOTE: This section describes how to access the Progress Explorer to configure the DataServer for ODBC on NT. It does not explain how to connect the DataServer. For connection instructions, see the "Starting and Stopping a Broker Process from the Progress Explorer and Connecting a Client" section in Connecting the DataServer." For information about the Progress Explorer, see the Progress Explorer online Help.

Follow these steps to access the Progress Explorer:

  1. Make sure that the Progress AdminServer is running.
  2. Start the Progress Explorer.
  3. From the Windows Desktop choose Start Programs Progress Progress Explorer Tool. The Progress Explorer appears in the MMC framework.

  4. Connect to localhost.
  5. From the Progress Explorer’s left pane, select the ODBC DataServer folder and double-click. The list of existing DataServer brokers for ODBC appears in the right pane.
  6. Select the DataServer instance whose properties you want to create or edit, and right-click. A pop-up menu appears.
  7. NOTE: The DataServer for ODBC installation provides one predefined DataServer Broker (odbbroker1) and one predefined NameServer (NS1). 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 the Progress Installation and Configuration Guide Version 9 for Windows or the Progress Installation and Configuration Guide Version 9 for UNIX for information about the NameServer’s role in a configuration.)

  8. Choose the Properties option from the pop-up menu. The Properties dialog box for that instance appears.
  9. 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.
NOTE: By default, your DataServer for ODBC broker instances are defined with a controlling NameServer and are provided with a default Data Service. Progress Software Corporation recommends using a NameServer configuration at all times. In such cases, the DataServer client’s initial connection is to the NameServer. However, you can alternatively connect the DataServer directly to the broker instance by setting the -DataService value to none in the connection parameters of your schema holder. If you will always use a -DataService value of none, you should remove the controlling NameServer from your broker instance definition. See the "Starting and Stopping a Broker Process from the Progress Explorer and Connecting a Client" section in "Connecting the DataServer" for more information about connecting the DataServer to the NameServer and the broker.

Do not simultaneously run some DataServers for ODBC under brokers with controlling NameServers and others directly under brokers (that is, without controlling NameServers). This defeats the purpose of using a NameServer to control brokers. If you do this, the benefits of the NameServer are lost and load balancing is ineffective. Progress Software Corporation recommends that you always use a NameServer, with one exception: you can choose initially to connect directly to a broker to simplify confirming an initial connection. Once you establish a connection, Progress recommends that you reintroduce the NameServer into your configuration.
