Distributing machines for a Unified Broker product
Figure 11–3 shows the maximum distribution of resources that you can achieve for any single Unified Broker product instance. For WebSpeed the, Unified Broker Client (WebSpeed Messenger) also resides on the same machine as the Web server, and Web clients (browsers, not shown) can reside anywhere on the Internet, intranet, or extranet serviced by the Web server.
Note: In Figure 11–3, the Unified Broker client element represents command-line utilities. For example, theASBMAN configuration utility and the ASCONFIG validation are both command-line utilities you can use for an AppServer. For more information about command-line utilities, see the "Command-line utilities reference" section.
The separate database host for a DataServer applies only to WebSpeed or the AppServer. For a DataServer, the Unified Broker host is the DataServer host. Note that whether the target database management system (DBMS) can reside on a separate database host or must reside on the same machine as the DataServer host depends on the DataServer and its platform.
Thus, you can distribute a Unified Broker instance and its management components among three separate machines on the same network. Also, the Unified Broker client and any single OpenEdge data source can reside on separate machines, for a total distribution of five machines, plus any machines in the same network that you might require for additional databases, DataServers, or other Unified Broker instances.
For for all Unified Broker products, these components must reside on the same machine:
Similarly, the NameServer, if it resides on its own machine, is installed with an administration framework, including an AdminServer and its own ubroker.properties file. If you use a text editor to modify the ubroker.properties file, the editor and configuration utilities must reside on the same machine as the Unified Broker or NameServer instance, or have network file system access to the respective Unified Broker and NameServer installation files.
