我有一个石英+ mysql + tomcat7 Lock wait timeout exceeded的问题。当我为dev和qa使用一台服务器时,我面临的问题没有出现,但是在部署之后,我开始在生产环境中看到一个问题(使用2台服务器)。quartz + mysql - 引发者:java.sql.SQLException:超出锁定等待超时;尝试重新启动交易

org.quartz.JobPersistenceException: Couldn't store trigger 'trigger1355274000000' for '1355274000000' job:Lock wait timeout exceeded; try restarting transaction [See nested exception: java.sql.SQLException: Lock wait timeout exceeded; try restarting transaction]

这是我的石英配置。

org.quartz.scheduler.instanceName = ApplicationDemoScheduler 
org.quartz.scheduler.instanceId = AUTO 

org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool 
org.quartz.threadPool.threadCount=10 
org.quartz.threadPool.threadPriority = 5 
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread=true 
org.quartz.scheduler.threadsInheritContextClassLoaderOfInitializer=true 
org.quartz.jobStore.misfireThreshold=180000 

org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX 
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate 
org.quartz.jobStore.useProperties=false 
org.quartz.jobStore.dataSource=qzDS 
org.quartz.jobStore.tablePrefix=QRTZ_ 
org.quartz.jobStore.isClustered=true 
org.quartz.jobStore.selectWithLockSQL=select LOCK_NAME from QRTZ_LOCKS where LOCK_NAME=? 
org.quartz.jobStore.clusterCheckinInterval = 20000 

org.quartz.scheduler.dbFailureRetryInterval=15000 


org.quartz.dataSource.qzDS.jndiURL=java:comp/env/jdbc/appDemoJndi 

而此数据源引用Tomcat中配置的数据源。

<Resource name="jdbc/appDemoJndi" auth="Container" type="javax.sql.DataSource" 
      username="testuser" password="test_pswd" 
      url="jdbc:mysql://localhost/testuser" 
      driverClassName="com.mysql.jdbc.Driver" 
      initialSize="20" maxWait="5000" 
      maxActive="40" maxIdle="5" 
     testWhileIdle="true" 
      testOnBorrow="true" 
      defaultAutoCommit="false" 
      maxOpenPreparedStatements="20" 
      validationQuery="select 1" 
      poolPreparedStatements="true"/> 

我不依赖任何休眠或任何东西。我不太确定这个错误是否与任何石英配置或MYSQL配置有关。

有没有人有过同样的问题并解决了它?请帮忙...

谢谢。

检查在mysql中的未决锁定来自MySQL的。你还有别的东西能访问那些可能导致锁定的表吗?你在QRTZ_LOCKS有奇怪的事吗? – poussma

此代码仅用于后端区域。所以根据我的理解,我不认为这张桌子是从其他地方使用的。我想知道是否因为其他服务器具有相同的配置。在LOCK表中,我看到了CALENDAR_LOCK,JOB_ACCESS,MISFIRE_ACCESS,STATE_ACCESS,TRIGGER_ACCESS。 – user826323

曾有同样的问题,最终提高了事务锁 的[mysqld] innodb_lock_wait_timeout = 120
