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	~ 500 MB, 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.
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 Compatibility of WSO2 Products.
If you have difficulty in setting up any WSO2 product in a specific platform or database, please contact us.
