Changing to MySQL

By default, WSO2 products use the embedded H2 database as the database for storing user management and registry data. Given below are the steps you need to follow in order to use a MySQL database for this purpose.

1 Creating the datasource connection to MySQL
2 Updating other configuration files
3 Creating database tables
4 Note to writers: Add this content at the end of the page if any of the additional databases is relevant to your product.
5 Changing the identity/storage/product-specific databases

Before you begin

You need to set up MySQL before following the steps to configure your product with MySQL. For more information, see Setting up MySQL.

Creating the datasource connection to MySQL

A datasource is used to establish the connection to a database. By default, WSO2_CARBON_DB datasource is configured in the master-datasources.xml file for the purpose of connecting to the default H2 database, which stores registry and user management data.

After setting up the MySQL database to replace the default H2 database, either change the default configurations of the WSO2_CARBON_DB datasource, or configure a new datasource to point it to the new database as explained below.

Follow the steps below to change the type of the default WSO2_CARBON_DB datasource.

Open the <PRODUCT_HOME>/repository/conf/datasources/master-datasources.xml file and locate the <datasource> configuration element.
You simply have to update the URL pointing to your MySQL database, the username, and password required to access the database and the MySQL driver details as shown below.
<datasource> <name>WSO2_CARBON_DB</name> <description>The datasource used for registry and user manager</description> <jndiConfig> <name>jdbc/WSO2CarbonDB</name> </jndiConfig> <definition type="RDBMS"> <configuration> <url>jdbc:mysql://localhost:3306/regdb</url> <username>regadmin</username> <password>regadmin</password> <driverClassName>com.mysql.jdbc.Driver</driverClassName> <maxActive>80</maxActive> <maxWait>60000</maxWait> <minIdle>5</minIdle> <testOnBorrow>true</testOnBorrow> <validationQuery>SELECT 1</validationQuery> <validationInterval>30000</validationInterval> <defaultAutoCommit>false</defaultAutoCommit> </configuration> </definition> </datasource>
You can update the configuration elements given below for your database connection.

Updating other configuration files

The registry.xml file (stored in the <PRODUCT_HOME>/repository/conf directory) specifies the datasource information corresponding to the database that stores registry information. Therefore, if you have changed the datasource name, you need to update the following accordingly:
<dbConfig name="wso2registry"> <dataSource>jdbc/MY_DATASOURCE_NAME</dataSource> </dbConfig>
The user-mgt.xml file (stored in the <PRODUCT_HOME>/repository/conf directory) specifies the datasource information corresponding to the database that stores user management information. Therefore, if you have changed the datasource name, you need to update the following accordingly:
<Configuration> <Property name="dataSource">jdbc/MY_DATASOURCE_NAME</Property> </Configuration>

Creating database tables

To create the database tables, connect to the database that you created earlier and run the relevant scripts.

Alternatively, you can create database tables automatically when starting the product for the first time by using the -Dsetup parameter as follows:

For Windows: <PRODUCT_HOME>/bin/wso2server.bat -Dsetup
For Linux: <PRODUCT_HOME>/bin/wso2server.sh -Dsetup

To create tables in the registry and user manager database (WSO2CARBON_DB), execute the relevant script as shown below.
mysql -u regadmin -p -Dregdb < '<PRODUCT_HOME>/dbscripts/mysql.sql';
Restart the server.
