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 on DEV/QA with a low number of users. 
  • ~ 1 GB heap size for PROD environment, supporting the most common use cases (OAuth/SAML, Federation, etc.) with moderate traffic.

Disk

  • ~ 1 GB, excluding space allocated for log files and databases.

Environment compatibility

Operating Systems/Databases/User Stores

  • WSO2 Identity Server 5.4.0 and beyond requires Oracle JDK 8 compliant JDK. This will run on most common platforms supporting Java 8. Any JDK except JDK 8 is not supported. We do not recommend OpenJDK as we do not support it or test our products with it.
  • 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 for use as a user store.
  • WSO2 Identity Server is shipped with a default embedded Apache DS. However, in a production environment, it is recommended to use an LDAP like OpenLDAP, due to scalability issues that exist with Apache DS.
  • For environments that WSO2 products are tested with, see Environments Tested with WSO2 Products. 
    See the  known incompatibilities  section to find out if this version of the product has issues running on your OS due to the JDK version.
  • If you have difficulty in setting up any WSO2 product in a specific platform or database, please contact us by clicking the Get Support button at the bottom of this page .
