Setting up a OneData Cluster
You can cluster OneData either vertically or horizontally based on your requirements and the resources available. This task describes how to cluster two instances of OneData horizontally or vertically. Based on the instructions, you can cluster the required number of instances in your environment.
To set up a OneData cluster using Apache web server as load balancer
2. Install two instances of OneData (referred to in these instructions as OD-1 and OD-2).
For more information on the installation steps, see Installing webMethods and Intelligent Business Operations Products.
For... | Install... |
Vertical clustering | OD-1 and OD-2 on the same cluster node in different install directories.  For OD-1Cluster Node IP: HostIP-1 HTTP Port: HTTPport-1 AJP Port: AJPport-1 For OD-2Cluster Node IP: HostIP-1 HTTP Port: HTTPport-2 AJP Port: AJPport-2 |
Horizontal clustering | OD-1 and OD-2 on different cluster nodes. For OD-1Cluster Node IP: HostIP-1 HTTP Port: HTTPport-1 AJP Port: AJPport-1 For OD-2Cluster Node IP: HostIP-2 HTTP Port: HTTPport-1 AJP Port: AJPport-1 |
3. For each OneData instance, navigate to the directory, <INSTALL_DIR>/profiles/ODE/configuration/tomcat/conf, and modify the server.xml file as follows:
Note: | Use the <AJPport> based on the type of clustering that you want to set up. |
For OD-1 add the following to server.xml:
<Connector port="<AJPport>" enableLookups="false" redirectPort="8443"
protocol="AJP/1.3" />
<Engine defaultHost="localhost" jvmRoute="worker1">
For OD-2 add the following to server.xml:
<Connector port="<AJPport>" enableLookups="false" redirectPort="8443"
protocol="AJP/1.3" />
<Engine defaultHost="localhost" jvmRoute="worker2">
4. Start all OneData instances and the Apache web server.
Note: | There is no sequence of starting up. But essentially to get the URL at least one OneData instance and the Apache web server must be running. |
5. In the browser, provide the link http://<LBHostIP>/onedata/ to access OneData on a cluster.
