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

• ~ 500 MB, 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 JDK 1.6.*/1.7.* compliant.    
• All WSO2 Carbon-based products are generally compatible with most common DBMSs. For more information, see Working with Databases.
  
• 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. 
• 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.
• We do not recommend OpenJDK.
