Configure a static ObjectGrid deployment topology by using a cluster descriptor XML file.
To deploy an ObjectGrid into a static environment, you must use a cluster descriptor XML file in addition to your ObjectGrid descriptor XML file. The endpoints for each ObjectGrid server must be defined in the cluster XML file. The cluster XML file is also used to set up partitioning and replication. Each partition is mapped to a replication group, and each replication group contains a set of predefined servers.
For details on how to construct an ObjectGrid XML file, see Introduction to ObjectGrid configuration. The companyGrid.xml
file is used as the ObjectGrid XML on which to build the cluster XML files in this example.
The following companyGridCluster.xml file is a very basic cluster XML file that excludes any optional XML attributes. This file is used as a starting point for detailing the elements and attributes of the cluster XML file, as well as building other examples. This file is compatible with the companyGrid.xml file.

The companyGridCluster.xml file places all of the CompanyGrid backingMaps into a single mapSet. This mapSet has only one partition. This partition is hosted on only one server. This mapSet is not partitioned nor replicated. For a complete description of the cluster descriptor XML file, see Cluster configuration reference.
