The embedded registry instance is configured by the registry.xml file which can be found in the ESB_HOME/repository/conf directory. In this configuration you could point the embedded registry to a database other than the default embedded H2 database. To change the database used by the registry or change the location of the database files, edit the following section of the registry.xml.

Code Block
<dbconfig<currentDBConfig>wso2registry</currentDBConfig>
<readOnly>false</readOnly>
<enableCache>true</enableCache>
<registryRoot>/</registryRoot>

<dbConfig name="wso2registry">
	<url>jdbc:h2:database/WSO2CARBON_DB</url>
	<username>wso2carbon</username>
	<password>wso2carbon</password>
	<driverName>org.h2.Driver</driverName>
	<maxActive>50</maxActive>
	<maxWait>60000</maxWait>
	<minIdle>5</minIdle>
</dbconfig>

    <dataSource>jdbc/WSO2CarbonDB</dataSource>
</dbConfig>

You can point the embedded registry to a database other than the default embedded H2 database or change the location of the database files, by editing the WSO2_CARBON_DB datasource configuration in the <ESB_HOME>/repository/conf/datasources/master-datasources.xml file as shown in the example below. 

Code Block
<datasources> 
        <datasource> 
            <name>WSO2_CARBON_DB</name> 
            <description>The datasource used for registry- local</description> 
            <jndiConfig> 
                <name>jdbc/WSO2CarbonDB</name> 
            </jndiConfig> 
            <definition type="RDBMS">
