Question

By using CronTriggerBean i have created two triggers(say trigger A & B) for invoking two different action. We have placed our project as .war in 2 servers.I am using JobStoreTX for clustering. The problem i am facing is that i want to cluster only one trigger i.e A and trigger B should not be clustered. Is there a way to specify through code which trigger has to be clustered. My code goes on as below.

<bean id="shedulerJobStoreTX" class="org.quartz.impl.jdbcjobstore.JobStoreTX>
  <property name="driverDelegateClass" value="org.quartz.impl. jdbcjobstore.oracle.OracleDelegate">
<property name="dataSource" value ="jndiDS"/>
        <property name="tablePrefix" value="someschemaName"/>
        <property name="isClustered" value="true"/>
<property name="clusterCheckinInterval" value="${someValue}"/>
    </bean>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">       
        <property name="triggers">
            <list>
                <ref bean="cronTrigger" />
                <ref bean="clusterCronTrigger"/>
            </list>
        </property>
    </bean>
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="runAppJob" />
        <property name="cronExpression" value="${someTimeValue1}"/>
    </bean>
    <bean id="clusterCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="runClusterJob" />
        <property name="cronExpression" value="${someTimeValue2}"/>
    </bean>

Hi, I have refined the code and the above said issue is not happening.PFB the code for the same.

  <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
                <list>
                    <ref bean="cronTrigger" />
                    <ref bean="clusterCronTrigger"/>
                </list>
            </property>
            <property name="quartzProperties">
            <props>
              <prop key="org.quartz.jobStore.isClustered">false</prop> 
              <prop key="org.quartz.scheduler.instanceId">AUTO</prop> 
              <prop key ="org.quartz.jobStore.class">org.quartz.impl.jdbcjobstore.
   JobStoreTX </prop> 
              <prop key="org.quartz.jobStore.tablePrefix">schemaName</prop> 
              <prop key="org.quartz.jobStore.driverDelegateClass"> org.quartz.impl.jdbcjobstore.oracle.OracleDelegate</prop> 
              <prop key="org.quartz.jobStore.selectWithLockSQL"> SELECT * FROM {0}LOCKS UPDLOCK WHERE LOCK_NAME= ?</prop>
            </props>
            </property>
            <property name="dataSource" ref="fsmJndiDataSource"/> 

But the problem on executing the above code is that i am getting the below exception when the quartz is trying to get the lock …”Invocation of init method failed; nested exception is org.quartz.SchedulerConfigException: Failure occured during job recovery. [See nested exception: org.quartz.impl.jdbcjobstore.LockException: Failure obtaining db row lock: ORA-00942: table or view does not exist“

Answer 1

Due to the message “ORA-00942: table or view does not exist”, I think the table “schemaNameLOCKS” is missing. Indeed, from the doc:

org.quartz.jobStore.selectWithLockSQL

Must be a SQL string that selects a row in the “LOCKS” table and
places a lock on the row. If not set, the default is “SELECT * FROM
{0}LOCKS WHERE SCHED_NAME = {1} AND LOCK_NAME = ? FOR UPDATE”, which
works for most databases. The “{0}” is replaced during run-time with
the TABLE_PREFIX that you configured above. The “{1}” is replaced with
the scheduler’s name.
