Question

我正在尝试在集群环境中运行quartz.net（使用单个数据库作为作业数据存储区的2个石英服务）。我在quartz.exe.config

中设置了quartz.jobStore.clustered = true和其他属性

<quartz>
    <add key="quartz.jobStore.tablePrefix" value="Qrtz_"/>
    <add key="quartz.jobStore.misfireThreshold" value="60000"/>
    <add key="quartz.jobStore.type" value="Quartz.Impl.AdoJobStore.JobStoreTX, Quartz"/>
    <add key="quartz.jobStore.driverDelegateType" value="Quartz.Impl.AdoJobStore.StdAdoDelegate, Quartz"/>
    <add key="quartz.jobStore.dataSource" value="myDS"/>
    <add key="quartz.dataSource.myDS.connectionString" value="Server=DEV1;user=dev2;password=P&ssW0rd;database=DATAU"/>
    <add key="quartz.jobStore.useProperties" value="false"/>

    <add key="quartz.dataSource.myDS.provider" value="SqlServer-20"/>
    <add key="quartz.scheduler.exporter.type" value="Quartz.Simpl.RemotingSchedulerExporter, Quartz"/>
    <add key="quartz.scheduler.exporter.port" value="555"/>
    <add key="quartz.scheduler.exporter.bindName" value="QuartzScheduler"/>
    <add key="quartz.scheduler.exporter.channelType" value="tcp"/>
    <add key="quartz.scheduler.exporter.channelName" value="httpQuartz"/>
    <add key="quartz.jobStore.clustered" value="true" />
</quartz>

但是，我收到了以下错误

错误Quartz.Impl.AdoJobStore.JobStoreTX - ClusterManager：管理集群时出错：获取数据库行锁定失败：第1行：FOR UPDATE子句仅允许DECLARE CURSOR。

我使用SQL2012（应用了最新的Service Pack）作为工作存储。

此外，我尝试使用以下属性替换锁定查询，如下所示

<add key="quartz.jobStore.selectWithLockSQL" value="SELECT * FROM &#123;0&#125;LOCKS UPDLOCK WHERE LOCK_NAME = '?'" />

如果我这样做，我会收到以下错误

[QuartzScheduler_QuartzScheduler-NON_CLUSTERED_MisfireHandler]错误Quartz.Impl.AdoJobStore.JobStoreTX - MisfireHandler：错误处理失误：获取数据库行锁定失败：违反PRIMARY KEY约束＆＃39; PK_QRTZ_LOCKS＆＃39;。无法在对象＆＃39; dbo.QRTZ_LOCKS＆＃39;中插入重复的密钥。重复键值为（QuartzScheduler，TRIGGER_ACCESS）。

尝试使用此配置设置：

properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.MSSQLDelegate, Quartz";

等等，那个人可能已经老了......

也许这一个：

    <add key="quartz.jobStore.lockHandler.type"
value="Quartz.Impl.AdoJobStore.UpdateLockRowSemaphore, Quartz"/>

从这个例子中找到：

我要从记忆中走出来....我没有曾经拥有的工作示例......

以下是一些有助于解决这个问题的代码：

所以也许使用“Quartz.Impl.AdoJobStore.SqlServerDelegate”而不是“Quartz.Impl.AdoJobStore.StdAdoDelegate”是一个选项。

namespace Quartz.Impl.AdoJobStore
{
    /// <summary>
    /// A SQL Server specific driver delegate.
    /// </summary>
    /// <author>Marko Lahma</author>
    public class SqlServerDelegate : StdAdoDelegate
    {


namespace Quartz.Impl.AdoJobStore
{
    /// <summary>
    /// Provide thread/resource locking in order to protect
    /// resources from being altered by multiple threads at the same time using
    /// a db row update.
    /// </summary>
    /// <remarks>
    /// <para>
    /// <b>Note:</b> This Semaphore implementation is useful for databases that do
    /// not support row locking via "SELECT FOR UPDATE" or SQL Server's type syntax.
    /// </para>
    /// <para>
    /// As of Quartz.NET 2.0 version there is no need to use this implementation for 
    /// SQL Server databases.
    /// </para>
    /// </remarks>
    /// <author>Marko Lahma (.NET)</author>
    public class UpdateLockRowSemaphore : DBSemaphore
    {
