Installation Prerequisites

Prior to installing any WSO2 Carbon based product, it is necessary to have the appropriate prerequisite software installed on your system. Verify that the computer has the supported operating system and development platforms before starting the installation.

System requirements

Memory	~ 2 GB minimum ~ 512 MB heap size. This is generally sufficient to process typical SOAP messages but the requirements vary with larger message sizes and the number of messages processed concurrently.
Disk	~ 1 GB minimum, excluding space allocated for log files and databases.

Environment compatibility

Operating Systems / Databases

All WSO2 Carbon-based products are Java applications that can be run on any platform that is Oracle JDK 1.6.*/1.7.* compliant. JDK 1.8 is not supported yet. Also, we do not recommend OpenJDK as we do not support it or test our products with it.
All WSO2 products are generally compatible with most common DBMSs. For more information, see Working with Databases.
If you have difficulty in setting up any WSO2 product in a specific platform or database, please contact us.
It is not recommended to use Apache DS in a production environment due to issues with scalability. Instead, it is recommended to use an LDAP like OpenLDAP for user management.
For environments that WSO2 products are tested with, see Environments Tested with WSO2 Products.

Required applications

The following applications are required for running the App Manager and its samples or for building from the source code. Mandatory installs are marked with *.

Application	Purpose	Version	Download Links
Oracle Java SE Development Kit (JDK)*	To launch the product as each product is a Java application. To build the product from the source distribution (both JDK and Apache Maven are required). To run Apache Ant.	1.6.24 or later / 1.7.* If you are using JDK 1.6, you might need to replace the Java Cryptography Extension (JCE) policy files in your JDK with the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy files. This will avoid "illegal key size" errors when you try to invoke a secured Web service. To build the product from the source distribution, you must use JDK 1.6 instead of JDK 1.7. Oracle and IBM JRE 1.7 are supported when running (not building) WSO2 products. We do not recommend OpenJDK as we do not support it or test our products with it.	http://java.sun.com/javase/downloads/index.jsp
Apache ActiveMQ JMS Provider	To enable the product's JMS transport and try out JMS samples. The ActiveMQ client libraries must be installed in the product's classpath before you can enable the JMS transport.	5.5.0 or later If you use any other JMS provider (e.g., Apache Qpid), install any necessary libraries and/or components.	http://activemq.apache.org
Apache Ant	To compile and run the product samples.	1.7.0 or later	http://ant.apache.org
SVN Client	To check out the code to build the product from the source distribution. If you are installing by downloading and extracting the binary distribution instead of building from the source code, you do not need to install SVN.		Linux - http://subversion.apache.org/packages.html Windows - http://tortoisesvn.net/downloads.html
Apache Maven	To build the product from the source distribution (both JDK and Apache Maven are required). If you are installing by downloading and extracting the binary distribution instead of building from the source code, you do not need to install Maven.	3.0.*	http://maven.apache.org
Web Browser	To access each product's Management Console. The Web Browser must be JavaScript enabled to take full advantage of the Management console. On Windows Server 2003, you must not go below the medium security level in Internet Explorer 6.x.
