ESB Installation Prerequisites

Prior to installing WSO2 Enterprise Service Bus, it is necessary to have appropriate prerequisite software installed on the system. Verify that the computer has the supported operating system and development platforms before starting the installation.

System Requirements

Confirm that the designated machine meets the following requirements:

Memory	No minimum requirements. A heap size of 256~512MB is generally sufficient to process typical SOAP messages. Requirements may vary with larger message size and on the number of messages processed concurrent.
Disk	No minimum requirements. The installation will require ~125 MB excluding space allocated for log files and Databases.
Operating System	Linux, Solaris, MS Windows - XP/ Vista (Not fully tested on Windows Vista). As WSO2 ESB is a Java application, it is generally possible to run it on other operating systems with a JDK 1.6.x runtime. Linux/Solaris is recommended for a production deployment.
