Installation Prerequisites

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, excluding space allocated for log files and databases.

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 or support OpenJDK.
• All WSO2 Carbon-based products are generally compatible with most common DBMSs. The embedded H2 database is suitable for development, testing, and some production environments. For most enterprise production environments, however, we recommend you use an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc. For more information, see Working with Databases. Additionally, we do not recommend the H2 database as a user store.
• It is not recommended to use Apache DS in a production environment due to scalability issues. Instead, use an LDAP like OpenLDAP for user management.
• For environments that WSO2 products are tested with, see Compatibility of WSO2 Products.
• If you have difficulty in setting up any WSO2 product in a specific platform or database, please contact us.

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.
• If you want 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 also supported when running (not building) WSO2 products.

• If you are using JDK 1.7 on a Mac OS, install the snappy-java library using the following steps:

  1. Download the snappy-java JAR for Mac and extract it to a preferred location. This folder will be referred to as <SNAPPY_HOME>.

  2. Copy the appropriate snappy-java library file i386.jnilib (32bit) or x86_64.jnilib (64bit) , which is in the <SNAPPY_HOME>/Mac/ directory, to the <ES_HOME> directory.
  For more information on installing snappy-java library, go to Snappy-java fails on Mac OS JDK 1.7.

• 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.x

http://maven.apache.org/  

To checkout the source, in order to build the product from the source distribution.
