Database Connections

A Progress application can access one or more Progress or non-Progress databases simultaneously. The databases can be located on different operating systems using different networking protocols. To access non-Progress databases, you must use the appropriate DataServer, such as ORACLE, or C-ISAM. You must connect to a database before you can access it. There are four ways to connect to a database:

Note that a multi-user application can simultaneously connect to a database for only as many times as specified in the Number of Users (–n) startup parameter. For information on exceeding this user count, see the "Connection Failures and Disruptions" section. For more information on database connection management, see the Progress Startup Command and Parameter Reference, the Progress Installation and Configuration Guide Version 9 for Windows or Progress Installation and Configuration Guide Version 9 for UNIX and the Progress Client Deployment Guide.
