Create a proxy server cluster

A proxy server cluster consists of a group of proxy servers. We can use either wsadmin.sh, or the console to create a cluster of proxy servers that can route requests to applications in a cell.

Member proxy servers in a proxy cluster can be created on any node in a cell and share the same proxy configuration. Before you define the proxy server cluster:

• Determine whether a domain name server (DNS), a load balancer, or a proxy server is going to be used to route requests to the proxy server cluster.

• Verify that v8.5 of the product is installed on the nodes that will belong to the proxy server cluster.

The main reason for creating a proxy cluster is to make it easier to administer multiple proxy servers. For example, if your proxy servers are members of a proxy server cluster, we can specify configuration settings for that proxy server cluster, and the settings are automatically applied to all of the proxy servers in that cluster. Creating a proxy server cluster also enables you to simultaneously start and stop all of the proxy servers in that cluster.

Avoid trouble: A proxy server cluster does not have all of the same functionality that an application server cluster has. For example, because there is no data replication among members of a proxy cluster. failover between proxy servers in the cluster is not supported. If a proxy server is down, all active connections owned by the proxy server go away and then incoming requests fail. Both proxy servers and proxy clusters support the high availability and failover of backend servers, such that the proxy server can detect if a backend server is down and then forward the requests to a server that has the session replicated.gotcha

Complete the following steps to create a proxy server cluster.

Click Servers > Clusters > Proxy server clusters > New to start the Create a new proxy server cluster wizard.

Results

You have created a proxy server cluster.

What to do next

Click Servers > Clusters > Proxy server clusters, select the newly created cluster, and then click Start to start the cluster, or click on the name of the new cluster to change its configuration settings, or add additional members to the cluster.

Subtopics

• Proxy server cluster collection
  Use this page to view information about and change configuration settings for a proxy server cluster. A proxy cluster consists of a group of proxy servers.

• Proxy server cluster settings
  Use this page to view a list of the proxy server clusters defined for the system, and the status of each of these clusters. We can also use this page to view or change the configuration settings for a specific proxy server cluster or to view the local topology of a specific proxy server cluster.

• Proxy server cluster member collection
  Use this page to view and manage proxy servers that belong to a proxy cluster.

• Proxy cluster member settings
  Use this page to manage the members of a proxy cluster. A proxy cluster of proxy servers is managed together and participate in workload management.

• Proxy cluster member templates collection
  Use this page to view the list of proxy cluster member templates that exist for this proxy cluster.

• Proxy cluster member template settings
  Use this page to modify proxy cluster member template attributes.

• Create a proxy cluster: Basic proxy cluster settings
  Use this page to enter the basic settings for a proxy cluster.

• Create a proxy cluster: Create first proxy cluster member
  Use this page to specify settings for the first proxy cluster member.

• Create a proxy cluster: Create additional proxy cluster members
  Use this page to create additional members for a proxy cluster. We can add a member to a proxy cluster when creating the proxy cluster or after we create the proxy cluster. A copy of the first proxy cluster member that we create is stored as part of the proxy cluster data and becomes the template for all additional proxy cluster members that we create.

• Create a proxy cluster: Summary settings
  Use this console page to view and save settings when creating a proxy cluster or proxy cluster member.
