Use this page to enter the basic settings for a cluster.
To view this administrative console page, click Servers > Clusters > New.
Specifies that the node scoped routing optimization is enabled or disabled. The default is enabled, which means that Enterprise JavaBeans (EJB) requests are routed to the client node when possible. Enabling this setting improves performance because client requests are sent to local enterprise beans.
Specifies that when the cluster is created, a memory-to-memory replication domain is created for this cluster. This replication domain has the same name as the cluster and has the default settings for a replication domain. The default settings for a replication domain are to create a single replica of each piece of data and to have encryption disabled. The Web container for each cluster member is also configured for memory-to-memory replication.
The default settings for the replication domain are good for an environment that has a middle to low traffic load. However, for an environment that has a high traffic load, you should change the replication domain configuration to a client-server replication because a client-server replication scales better. If you change the settings for one cluster member, you should change them for all cluster members.
To modify the replication domain properties, in the administrative console, click Environment > Replication domains > replication_domain_name.
To modify the properties for a Web container, in the administrative console, click Servers > Clusters >cluster_name > Cluster members > cluster_member_name > Session management > Distributed environment settings.
Specifies whether to create an empty cluster or to add an existing application server to the cluster.
To create a cluster without an existing application server as a cluster member, click Do not include an existing server in this cluster.
To add an existing server to the cluster, click Select an existing server to add to this cluster and choose the application server to add to the cluster. This application server becomes a template for any additional cluster members that you add to the cluster. When adding servers to a cluster, the only way to remove an application server from a cluster is to delete the application server.
Specifies the amount of work that is directed to the application server.
If the weight value for the server is greater than the weight values that are assigned to other servers in the cluster, the server receives a larger share of the cluster workload. The value can range from 0 to 20. Enter zero to indicate that you do not want requests to route to this application server unless this server is the only server that is available to receive requests.
