WSO2 EMM provides scripts for installing and configuring MySQL,H2, Oracle, MSSQL and PostgreSQL.
The default database of the user manager is the H2 database that comes with WSO2 EMM. You can configure it to point to databases by other vendors such as MySQL, Oracle, PostgreSQL, and Microsoft SQL Servers, using the scripts provided by WSO2 for installing and configuring relational databases. The scripts in the
<PRODUCT_HOME>/dbscripts/ folder are available for all WSO2 products. They store data related to WSO2 Carbon, on top of which all WSO2 products are built.
The embedded H2 database is suitable for development. However, for most enterprise testing and production environments we recommend an industry-standard RDBMS such as MySQL etc.
