We have enabled quartz timer service in our jBPM server. We have created a quartz datasource and updated the timer-service like below

<timer-service thread-pool-name="default" default-data-store="db-store">

    <data-stores>

        <database-data-store name="db-store" datasource-jndi-name="java:jboss/datasources/quartzDS"/>

    </data-stores>

</timer-service>

But when we start server, we get an error from ejb-timer service

Caused by: java.lang.RuntimeException: org.postgresql.util.PSQLException: ERROR: relation "jboss_ejb_timer" does not exist

Position: 463

Is there a way to disable ejb-timer service if we are using quartz timer?
