The Cluster Partition File
The cluster partition file, clusterPartitions.xml, defines the partitions on the cluster and assigns nodes to each partition. The data structure for a partition in the clusterPartitions.xml file looks like this:
<ClusterPartitions>
<Partition name="partitionName"
frontEndUrl="http://some.url.com">
<Component name="componentName">
</Component>
</Partition>
</ClusterPartitions>
where:
The table describes the expected values of configurable attributes in the clusterPartitions.xml file.
partitionName | Is the name assigned to the partition. Other configuration files use this name to identify the partition. |
some.url.com | An alternate Front End URL. The frontEndUrl attribute is optional, allowing the partition to use a different Front End URL than the cluster as a whole. If you omit this attribute, the partition uses the frontEndUrl value in the cluster.xml file. |
componentName | The name of a component (a cluster node) that is part of the partition. The component name is the same as the component name in the cluster.xml file. |
Entries in clusterPartitions.xml conform to the following rules:
There is one
Partition element for each partition in the cluster. There is always at least one
Partition element.
Each
Component element represents a cluster node that is a member of the partition. There can be zero or more nodes specified for a partition.
If there is only one
Partition element in the file, all cluster nodes are members of that partition, regardless of whether they are represented by a
Component element.
Any cluster node not specifically represented within a
Partition element is automatically a member of the last partition defined in the file.
