关于quartz集群的问题。

配置文件如下，用的1.6.3的jar包



#============================================================================

# Configure Main Scheduler Properties  

#============================================================================

org.quartz.scheduler.instanceName = BICSJOB

org.quartz.scheduler.instanceId = AUTO

#============================================================================

# Configure ThreadPool  

#============================================================================

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

org.quartz.threadPool.threadCount = 3

org.quartz.threadPool.threadPriority = 5

#============================================================================

# Configure Plugins 

#============================================================================

#org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingJobHistoryPlugin

org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin

org.quartz.plugin.jobInitializer.fileName = idcheck_Job.xml,pboc_Job.xml

org.quartz.plugin.jobInitializer.overWriteExistingJobs = true

org.quartz.plugin.jobInitializer.failOnFileNotFound = true

org.quartz.plugin.jobInitializer.scanInterval = 10



org.quartz.jobStore.misfireThreshold = 60000   

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX   

#org.quartz.jobStore.driverDelegateClass =   org.quartz.impl.jdbcjobstore.oracle.OracleDelegate

#org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.WebLogicDelegate

org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.oracle.weblogic.WebLogicOracleDelegate

org.quartz.jobStore.tablePrefix = QRTZ_   

org.quartz.jobStore.dataSource = myDS   

org.quartz.jobStore.isClustered = true  

org.quartz.jobStore.clusterCheckinInterval = 20000

每次启动都抛异常



 Error starting background-task for watching jobs file.

org.quartz.ObjectAlreadyExistsException: Unable to store Job with name: 'JobInitializationPlugin_jobInitializer_wxApp_Job_xml' and group: 'JobInitializationPlugin', because one already exists with this identification.

看了源码(如下)发现只有非集群环境下才会先清掉数据库已有的数据在重新插入，而集群环境下不会做清数据的动作所以抛了上面这个异常，想问如果解决这个问题只能改源码了么。。。？



 if (!isClustered()) {

            try {

                cleanVolatileTriggerAndJobs();

            } catch (SchedulerException se) {

                throw new SchedulerConfigException(

                        "Failure occured during job recovery.", se);

            }

        }
