Question

I can’t find any examples online of how to configure two separate databases for Magento – one for read requests and one for write requests. I assume that this should happen in app/etc/local.xml but I don’t know what the syntax is. Does anybody know the syntax or have a link to a blog post or something that my searching didn’t turn up?

I’m running Magento 1.6.1.0

Thanks

In your app/etc/local.xml fill <resources> in next way:

    <resources>
        <db>
            <table_prefix><![CDATA[]]></table_prefix>
        </db>
        <core_read>
            <connection>
                <use /> 
                <host><![CDATA[localhost]]></host>
                <username><![CDATA[root]]></username>
                <password><![CDATA[]]></password>
                <dbname><![CDATA[db_read_name]]></dbname>
                <initStatements><![CDATA[SET NAMES utf8]]></initStatements>
                <model><![CDATA[mysql4]]></model>
                <type><![CDATA[pdo_mysql]]></type>
                <pdoType><![CDATA[]]></pdoType>
                <active>1</active>
            </connection>
        </core_read>
        <core_write>
            <connection>
                <use />
                <host><![CDATA[localhost]]></host>
                <username><![CDATA[root]]></username>
                <password><![CDATA[]]></password>
                <dbname><![CDATA[db_write_name]]></dbname>
                <initStatements><![CDATA[SET NAMES utf8]]></initStatements>
                <model><![CDATA[mysql4]]></model>
                <type><![CDATA[pdo_mysql]]></type>
                <pdoType><![CDATA[]]></pdoType>
                <active>1</active>
            </connection>
        </core_write>
    </resources>
