Connecting To a Progress Database
WebSpeed supplies a demonstration Progress database called Sports2000. You can use the Sports2000 database to run the sample applications and experiment with your first WebSpeed applications.
In a local configuration, the Progress database resides on the same machine as the WebSpeed Transaction Server. The structure of a remote configuration can vary. "WebSpeed Configurations," shows some of the possibilities. When you are developing in a client/server environment, you can connect to the database in single-user mode. When you develop WebSpeed applications on a Windows system with the WebSpeed Workshop, you must run the Progress database in a multi-user mode. In the WebSpeed Workshop development environment, several Agents must connect to the database simultaneously: one for the Progress Explorer, another for the WebSpeed WebTools, and one for the AppBuilder.
See the chapter on startup in the Progress Database Administration Guide and Reference for more information on running the Progress database server and the parameters that you can specify.
You provide the information that an Agent needs to connect to a database when you configure a WebSpeed Transaction Server and specify the Agent options for its pool of Agents. The WebSpeed Agent is a 4GL client running in batch mode and can accept nearly all the startup parameters a standard client can.
This is a sample srvrStartupParam setting in
ubroker.properties
for the sample Transaction Server, WSbroker1, running on a Windows system:
WebSpeed provides many parameters that allow you to control connections to the database and make adjustments to increase performance. These include parameters for controlling record-buffer size, cursor size, and read-only access. In addition to database connection parameters, WebSpeed provides session parameters that allow you to control the conditions under which it compiles your r-code and Web objects and how to handle code page issues. See the Progress Startup Command and Parameter Reference for details on session parameters.
