mysql - quartz + mysql - 由 : java. sql.SQLException: Lock wait timeout exceeded 引起；尝试重启交易

Question

我在 quartz + mysql + Tomcat7 中遇到了 Lock wait timeout exceeded 问题。当我将一台服务器用于开发和质量检查时，我面临的问题并没有出现，但在部署后我开始在生产环境(有 2 台服务器)中看到问题。

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 quartz 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

并且这个数据源是引用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。我不太确定此错误是否与任何 quartz 配置或 MYSQL 配置有关。

有遇到同样问题并解决的吗？请帮助...

谢谢。

同样的问题最终增加了事务锁 [mysqld] innodb_lock_wait_timeout=120
