You can add the DBlookup mediator configurations to the registry. Refer to the following sample configuration [1].

<dblookup xmlns="http://ws.apache.org/ns/synapse">
<connection>
    <pool>
        <password key="conf:/repository/esb/password"/>
        <driver key="conf:/repository/esb/driver"/>
        <url key="conf:/repository/esb/url"/>
        <user key="conf:/repository/esb/username"/>
    </pool>
</connection>
</dblookup>
