Java 获取锁期间超时（quartz-1.5.2）（ORA-01013用户请求取消当前操作）

我们使用的是石英-1.5.2。在我们的应用程序中，在一个场景中，调度程序正在尝试删除作业

scheduler.deleteJob（jobName，groupName）

我们遇到了以下异常


org.quartz.impl.jdbcjobstore.LockException: Failure obtaining db row lock: ORA-01013: 
user requested cancel of current operation

我已经调试了StdRowLockSemaphore.java获取锁方法

ps = conn.prepareStatement(selectWithLockSQL);
ps.setString(1, lockName);
if(log.isDebugEnabled())
    log.debug( "Lock '" + lockName + "' is being obtained: " + Thread.currentThread().getName());
rs = ps.executeQuery();

ps.executeQuery（）中出现超时

它正在尝试运行一个简单的查询

SELECT * FROM QRTZ_LOCKS WHERE LOCK_NAME = 'TRIGGER_ACCESS' FOR UPDATE;

这不是一直都会发生的，当服务器启动时，它运行没有任何问题，几个小时后我们就遇到了这个问题

请查找石英的属性

<prop key="org.quartz.scheduler.instanceName">CargoresScheduler_${cargores_server_type}</prop>
            <prop key="org.quartz.scheduler.instanceId">AUTO</prop>
            <prop key="org.quartz.threadPool.class">org.quartz.simpl.SimpleThreadPool</prop>
            <prop key="org.quartz.threadPool.threadCount">10</prop>
            <prop key="org.quartz.threadPool.threadPriority">5</prop>
            <prop key="org.quartz.jobStore.misfireThreshold">60000</prop>

当quartz遇到此错误时，您是否可以尝试手动运行查询“SELECT*FROM QRTZ_LOCKS WHERE LOCK_NAME='TRIGGER_ACCESS'FOR UPDATE；”以查看发生了什么情况？基本上确定您有这样一个表，并且有一个具有lock\u name trigger\u access的条目。好的，我将尝试该选项srinivas我们无法访问该表，设置了某种行锁。我已经用线程转储更新了这个问题。因为它正在等待执行查询，所以从{0}锁中选择*FROM{0}锁，其中LOCK_NAME=？对于更新，我已使用SELECT*从{0}锁重写属性org.quartz.jobStore.selectWithLockSQL，其中LOCK_NAME=？对于更新等待5，现在没有超时
