Configuring the Remote DataServer
In configurations that include a remote host, two DataServer processes run on the host machine:
- Broker—The DataServer broker (
_probrkr.exe
) or the broker for the Progress Explorer on the host machine determines the types of requests coming over the network and starts (spawns) the appropriate DataServer (_odbsrv.exe
) for the client process.- DataServer—The DataServer (
_odbsrv.exe
) on the host machine accesses the ODBC data source and communicates with the client process.NOTES:
- The Progress ODBC DataServer component is a client with respect to the ODBC data-source configuration even though from the Progress point-of-view it resides on the server machine. As a result, your ODBC software installation and any client software required by the data source must reside on the machine from which the DataServer and the broker processes will execute. In the remote DataServer configuration, the Progress ODBC client component requires no special software or configuration; it requires only a standalone Progress NT or UNIX client.
- Progress has no restrictions regarding the location of the actual database that your ODBC data source name connects. See your data source documentation for possible database configurations.
Before you can run the server components, you must configure the DataServer by setting the required environment variables on the host machine. On NT, you configure using ProControl or the Progress Explorer tool. See the "Configuring with ProControl" or the "Configuring with the Progress Explorer" section for details.
NOTE: Configurations that use a remote DataServer on NT are available only with the Enterprise DataServer for ODBC.
