All WSO2 products are shipped with default H2 databases (embedded) for storing data. These are stored in the
- Carbon database:
WSO2CARBON_DB.h2.dbis the main Carbon database in a WSO2 product. This stores registry and user manager data by default. In addition, if the product uses features of WSO2 Identity Server or WSO2 Enterprise Store (ES), data which are specific to those will by default reside in the embedded Carbon database. However, for production environments, we recommend you to use separate RDBMS databases to store identity-related and storage-related data.
- Product-specific databases: In addition to the main Carbon database, your product may have other databases for storing product specific data.
These embedded H2 databases are suitable for development, testing, and some production environments. For most production environments, however, we recommend you to use an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc.
You can use the scripts provided with WSO2 products to install and configure several other types of relational databases, including MySQL, IBM DB2, Oracle, and more.
