Chapter 5: Configuring the DataServer 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. 2. Set your MS SQL Server instance username (-U) and password (-P) connection parameters for the schema holder. Progress Software Corporation recommends that you use the -U and -P convention to establish the username and password. 3. Set up your connection, using parameters to run the schema holder. This step shows examples from which you can model your connection: a. The following example shows how to set up the connection in Windows in a single-user mode: prowin32 f:\wrk\holder -1 -RO -db MSS_DB_DSN -ld MSS_DB_INS -dt MSS -H MSS_DSRV_Host -S 5162 -DataService mssbroker1 -Dsrv SVUB,1 Note that although the schema holder is defined as a single-user mode, access to the MS SQL Server instance is in multi-user mode. b. The following example shows how to set up the connection in Windows in a multi-user mode: prowin32 holder -H MSS_DSRV_Host -S Holder_Service -db MSS_DB_DSN -ld MSS_DB_INS -dt MSS -H MSS_DSRV_Host -S 5162 -DataService mssbroker1 -Dsrv SVUB,1 c. The following example shows how to set up the connection on UNIX: mpro holder -H MSS_DSRV_Host -S Holder_Service -db MSS_DB_DSN -ld MSS_DB_INS -dt MSS -H MSS_DSRV_Host -S 5162 -DataService mssbroker1 -Dsrv SVUB,1 The following list identifies the values used in the examples shown in Step 3: MSS_DB_DSN Identifies the ODBC Data Source name. MSS_DB_INS Identifies the MS SQL Server instance name. MSS_Dsrv_host Identifies the name of the MSS DataServer broker host. 188 OpenEdge Data Management: DataServer for Microsoft SQL Server
5162 Configuring a remote DataServer Identifies the NS1 NameServer default port where the MSS broker is registered. Holder_Service Identifies the service name used to server the database holder; however, it can also be a port number. For details about the database connection parameters noted in each example in Step 3 of this procedure, see the “Connecting a schema holder at startup” section on page 219. Caution: Do not simultaneously run some DataServers for MS SQL Server 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 (PSC) 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, PSC recommends that you reintroduce the NameServer into your configuration. Once you have completely set up your environment, you can build the schema holder for your MS SQL Server database. See the “Creating a schema holder” section on page 197 for instructions. Configuring from the command line You can configure a remote DataServer broker process from the command line. You can use the _probrkr.exe executable or use the mssman.bat utility within OpenEdge Management or OpenEdge Explorer, the command line equivalent of using OpenEdge Management or OpenEdge Explorer. Before you start the configuration tasks, make sure that you have installed your ODBC software and any data source-specific client software on your host machine. Also make sure that you have registered all of your data sources. See the “Configuring an ODBC driver and registering the data source” section on page 184 for details. To configure from the command line: • When using the OpenEdge broker (_probrkr.exe), you set the environment variables described in this section from the command line using environment-variable commands at the DOS shell prompt. • When using the mssman.bat utility within OpenEdge Management or OpenEdge Explorer, set the environment variables described in this section in the environment section of your broker properties file for the specific broker instance definition. • You must set your environment variables in the same environment (DOS shell) from which you plan to run the DataServer.
