DataServer Configurations
The Enterprise DataServer for ODBC can run in a variety of configurations. Depending on its configuration, it is either a single Progress executable or a set of Progress executables that you can distribute across operating systems. There are two general types of configurations—local and remote—with variations on each type:
- Local DataServer—All of the DataServer software components, the schema holder, the ODBC software, and your data-source client software run on one machine.
- Remote DataServer—The DataServer software components run on different machines. Typically, the Progress client component runs on one machine, while the Progress server component runs on another machine called the host machine. Note that the ODBC software and any client software required by the data-source vendor run on the same machine as the DataServer software modules. In the remote DataServer configuration, this is the host machine. The host machine and the machine on which the client runs communicate through Progress networking (TCP/IP). A remote configuration exists within the framework of a distributed application, whereby DataServers are spawned on the host machine using the Progress ProBroker executable or broker in the Progress Explorer administration framework.
The Personal DataServer for ODBC runs only in a local DataServer environment. It cannot be run in the remote (or distributed) DataServer configuration.
