To enable the clusters:
- Open the ClusterConfig.xml file for editing, located at the following location:
On UNIX operating system:
DOMAIN_HOME/config/fmwconfig/biconfig/core
On Windows operating system:
DOMAIN_HOME\config\fmwconfig\biconfig\core
- Locate the following:
<ClusterEnabled>false</ClusterEnabled>
Change it to the following:
<ClusterEnabled>true</ClusterEnabled>
- Save and close the file.
