Setting Up the Java Cluster
Purpose
The appropriate cluster setup is one of the main prerequisites for the good performance of your system.
A Java cluster consists of the following components:
·
One or more
Java instances
· One or more databases.
When installing the
J2EE Engine, you can choose to install the above components on a single host
or on different hosts. In addition, you can choose the number of server processes
in each Java instance. These components form the initial configuration of your
system. It is typically based on the expected system load defined by such
factors as the anticipated throughput and number of users, as well as on the
available hardware resources.
Implementation Considerations
If the system load is bigger than expected and the cluster that you have initially set up does not scale well, you can easily resize it by:
·
Installing new Java
instances
·
Adding server
processes to existing Java instances
