Operating Systems/ Databases/ User Stores

  • WSO2 Identity Server requires an Oracle JDK 11 or JDK 8 compliant JDK. This will run on most common platforms that support Java 11 or Java 8. .
  • All WSO2 Carbon-based products are generally compatible with most common DBMSs. The embedded H2 database is suitable for development and testing. For enterprise production environments we recommend an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc. For more information, see Working with Databases .
  • WSO2 Identity Server supports using any of the following as a user store :


  • WSO2 Identity Server is shipped with a default embedded Apache DS that is suitable for development purposes. WSO2 does not recommend using Apache DS in a production environment due to scalability issues that exist with Apache DS.
  • WSO2 does not recommend using the H2 database as a user store in production environments. However, you can use the H2 database for development purposes if necessary.

  • For environments that WSO2 products are tested with, see Environment Compatibility .
  • If you have difficulty setting up any WSO2 product in a specific platform or database, contact WSO2.
