Site Topology
The site topology file contains deploy-time information such as what processing units to deploy to specific machines in your environment.
You need to know information about the machines that will host the agents you plan to deploy, for example information about the operating system and IP address of the machines.
You also need to know what remote invocation software you will use to start remote processes on these machines: TIBCO Hawk, PSTools, or SSH.
When possible, use the graphical site topology file editor in TIBCO BusinessEvents Studio. It provides validation and structure that are helpful.
When working on runtime installations, however, it may not be possible to use TIBCO BusinessEvents Studio. An annotated site topology file template is available, so you can edit the XML-based topology file in a text editor. You can access it at the following location:
BE_HOME/mm/config/site_topology_template.st
If you are editing the file directly, adapt the GUI-based instructions accordingly. The configuration requirements are the same in both cases.
Using the canvas-based editor in TIBCO BusinessEvents Studio, you can create a visual representation of the desired site topology. Using the tabs that show the properties, you can configure each item represented by the topology diagram icons: the cluster, hosts, deployment units, and processing unit configurations.
The output of this activity is an XML file used in MM. A summary of the steps is shown below. For detailed steps, see Site Topology in TIBCO BusinessEvents Studio.
- Configuring the Site Topology
The site topology is best configured using the graphical site topology file editor in TIBCO BusinessEvents Studio. - Project, Master and Deployed Locations of CDD and EAR Files
In the topology file, reference three locations for the CDD and EAR files. - Deployment-Specific Processing Units and Global Variables
In general, you can reference one processing unit multiple times to create different processing unit configurations (PUCs). However processing units that have deployment-specific settings cannot be used in this flexible manner. - Site Topology in TIBCO BusinessEvents Studio
Before you begin, ensure that you have a valid CDD file. The processing units that you deploy to the various hosts are defined in the CDD.
