Installation Prerequisites

Prior to installing any WSO2 Identity Server, 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 requires an Oracle JDK 8 compliant JDK. This will run on most common platforms that support 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 :

Note

  • 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.
