(7.2.z) EJB Timer is not properly set when the database is different than the defaults

XMLWordPrintable

      When using EJB timers the tables will be created during startup based on the database type.
      If we set the database different than the default names, i.e. mariadb, mysql, it will fail:

      timer-store example:

                  <timer-service thread-pool-name="default" default-data-store="ejb_timer-EJB_TIMER_ds">
		<data-stores>
		    <file-data-store name="default-file-store" path="timer-service-data" relative-to="jboss.server.data.dir"/>
		    <database-data-store name="ejb_timer-EJB_TIMER_ds" datasource-jndi-name="java:jboss/datasources/jbpmDS_EJBTimer" database="mysql57" partition="ejb_timer-EJB_TIMER_part" refresh-interval="30000"/>
		</data-stores>
	   </timer-service>

      This issue was spotted on OpenShift environment, the behavior there is to use as the database type on the datastore the same value than the datasource driver name, in this specific case, we we're trying a custom mysql jdbc driver version and named it to mysql57.
