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 greater than expected and the cluster that you have initially set up does not scale well, you can resize it by:
· Installing new Java instances
· Adding server processes to existing Java instances
