Setting up MySQL Cluster

For instructions on configuring a MySQL cluster (NDB), see Deploying WSO2 Products on MySQL Cluster, which is published in the WSO2 library.

This page explains how to point WSO2_CARBON_DB into a MySQL cluster (NDB).

After creating the database in a MySQL cluster, modify the default datasource configuration in the <APIM_HOME>/repository/conf/datasources/master-datasources.xml file. Replace the URL, username, password, driver class name and any other values with your custom values.

<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://192.168.43.238:3306/carbondb?relaxAutoCommit=true&?autoReconnect=true</url>
                 <username>root</username>
                 <password>root123</password>
                 <driverClassName>com.mysql.jdbc.Driver</driverClassName>
                 <maxActive>50</maxActive>
                 <maxWait>60000</maxWait>
                 <testOnBorrow>true</testOnBorrow>
                 <validationQuery>SELECT 1</validationQuery>
                 <validationInterval>30000</validationInterval>
             </configuration>
         </definition>
     </datasource>

Copy the MySQL JDBC driver library into <APIM_HOME>/repository/components/lib directory.
To create the database tables related to the user store and registry, execute the cluster script located inside the <APIM_HOME>/dbscripts/mysql_cluster.sql file.
If you prefer to create database tables during server startup, replace the content of the <APIM_HOME>/dbscripts/mysql.sql file with the content of the <APIM_HOME>/dbscripts/mysql_cluster.sql file and start the API Manager instance with -Dsetup vm argument.
