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 WSO2AM_DB into a MySQL cluster (NDB), as Fail Over.

1. After creating the database in a MySQL cluster, modify the default datasourceconfiguration 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>WSO2AM_DB</name>
            <description>The datasource used for registry and user manager</description>
            <jndiConfig>
                <name>jdbc/WSO2AM_DB</name>
            </jndiConfig>
            <definition type="RDBMS">
                <configuration>
   				 <url>jdbc:mysql://192.168.58.215:3306,192.168.58.216:3306/WSO2AM_DB?autoReconnect=true&amp;relaxAutoCommit=true&amp;useSSL=false&amp;failOverReadOnly=false</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>

   Connection URL should be in the below format for Fail Over Configuration.

   <url>jdbc:mysql://[primary_mysql_node_IP]:[port],[secondary_mysql_node_IP]:[port]/[DB_Name]?autoReconnect=true&amp;relaxAutoCommit=true&amp;useSSL=false&amp;failOverReadOnly=false</url>

2. Copy the MySQL JDBC driver library into <APIM_HOME>/repository/components/lib directory.
3. To create the related API Manager database tables in the MySQL cluster databse, execute the cluster script located inside the <APIM_HOME>/dbscripts/apimgt/mysql_cluster.sql file.

4. 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/apimgt/mysql_cluster.sql file and start the API Manager instance with -Dsetup vm argument.
   
   

   Note that we recommend to useFail Over configuration with the MySQL cluster, over Load Balaced configuration
