Managing a proxy server cluster
You can use either the administrative console, or the wsadmin tool to manage a proxy server cluster .
Before you begin
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, you 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 some 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, on the other hand, 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.
- When a proxy server is part of a proxy server cluster, the only HTTP proxy server setting that can be set at the proxy server level is Local outbound TCP address. The other HTTP proxy server settings must be set at the proxy cluster level.
