Chapter 5: Configuring the DataServer Table 27 describes the environment variables that you must set. Table 27: Environment variables for the remote DataServer DSLOGDIR (Optional) Variable Description The pathname of the log file that OpenEdge uses to keep track of DataServer processes and error messages. By default, OpenEdge writes to %DSLOGDIR%\dataserv.lg where %DSLOGDIR% is resolved to directory path of the log file dataserv.lg. MSSSRV The pathname of the OpenEdge server executable. This variable is required only when the DataServer is spawned using the OpenEdge broker (_probrkr.exe). When using mssman, this setting is satisfied by the srvrExecFile setting in the broker properties file. PROBRKR (Optional) The pathname of the broker executable. When using the OpenEdge broker (_probrkr.exe), set this variable on the host machine to the broker executable name. When using mssman.bat, this setting is satisfied by the broker instance definition in the broker properties file. PROSTARTUP The pathname of your default OpenEdge startup (.pf) file. To set the Message Buffer Size (-Mm) startup parameter for the broker to a value different from the 1024 default buffer size, you must set the PROSTARTUP environment variable equal to the path and name of the .pf file that contains the -Mm parameter. This approach ensures that your value is recognized and therefore used by the broker when it starts. Only Windows clients must use this technique. Note: If you use the command line utility and intend to set the -Mm startup parameter to a value other than 1024, you must use the .pf file with the PROSTARTUP variable set. UNIQUE_DSLOG Used to generate unique log file name on the server with dataserv_.lg, where pid is the process-id of server. When set, the designated DataServerlog log file name becomes a root name. Can be disabled by unsetting the environment variable. Once you have completely set up your environment, you can build the schema holder for your MS SQL Server database and connect using the client executable. See the “Creating a schema holder” section on page 197 for instructions. 190 OpenEdge Data Management: DataServer for Microsoft SQL Server
The ubroker.properties file Configuring a remote DataServer When using the Unified Broker framework, you configure the DataServer for MS SQL Server by editing the OpenEdge-install-dir\properties\ubroker.properties file. This file stores configuration definitions for instances of many OpenEdge products. For a complete list of products and a detailed discussion of the Unified Broker Framework, see OpenEdge Getting Started: Installation and Configuration. When you use this file to configure the DataServer for MS SQL Server, you provide information that enables the host to start a broker that spawns the appropriate DataServer process (_msssrv.exe). Each configuration definition contains the environment variable and property settings for a broker instance. The command-line utilities use this file to store, validate, and manage the configurations for these brokers. A single copy of this file maintains all supported broker configurations for each OpenEdge installation. Editing the ubroker.properties file The simplest way to make configuration changes to the ubroker.properties file is to copy an existing broker or NameServer definition and then modify the copied values as required for your configuration. You must ensure that all related properties and sections of the file are properly specified for each broker or NameServer instance. Note: Be sure to preserve the original %DLC%\properties\ubroker.properties file. Rename the original file and work with a copy of the file. You must name the copy of the file ubroker.properties. Table 28 describes the sections in the ubroker.properties file that apply to the DataServer for MS SQL Server. The file configures a default NameServer named NameServer.NS1 and a default broker named mssbroker1, which you can use either without editing or as templates for your own configuration specifications. Table 28: DataServer for MS SQL Server sections of the ubroker.properties file (1 of 4) Product Section Description All products ParentGroup Defines the name of each NameServer and product broker parent entity. Environment Default environment variable settings for all NameServers and product brokers. UBroker Defines default property settings for all product brokers.
