Sun Cluster HA for Apache Tomcat as a scalable configuration

You can use Sun Cluster HA for Apache Tomcat in a scalable configuration if it is guaranteed, that the source ip address remains the same during a session context. This guarantee is achieved in example in an intranet.

If the source ip address might change during a session context and a scalable configuration is required, Apache Tomcat needs to be configured with session replication. This can be done by the application using a global file system or a database.

Caution – Caution –

You will get a performance penalty from this approach.

You will get better performance using Tomcats inbound memory session replication for a scalable configuration with changing source ip addresses.
