Environment compatibility

Operating Systems / Databases

All WSO2 Carbon-based products are Java applications that can be run on any platform that is JDK 1.7.* compliant. Also, we do not recommend or support OpenJDK.
All WSO2 Carbon-based products are generally compatible with most common DBMSs. For more information, see /wiki/spaces/~yohanna@wso2.com/pages/21233785.
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.
