quartz threadPool 设置问题

用 Quartz 进行作业调度 使用JDBCJobStore提供的数据持久性时，可以在quartz.properties设置一些参数:例如


org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true

# Using RAMJobStore
## if using RAMJobStore, please be sure that you comment out
## org.quartz.jobStore.tablePrefix, org.quartz.jobStore.driverDelegateClass, org.quartz.jobStore.dataSource
#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

# Using JobStoreTX
## Be sure to run the appropriate script(under docs/dbTables) first to create database/tables
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX

# Configuring JDBCJobStore with the Table Prefix
org.quartz.jobStore.tablePrefix = QRTZ_

# Using DriverDelegate
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

org.quartz.jobStore.useProperties = true

# Using datasource
org.quartz.jobStore.dataSource = qzDS

# Define the datasource to use
org.quartz.dataSource.qzDS.driver = net.sourceforge.jtds.jdbc.Driver
org.quartz.dataSource.qzDS.URL = jdbc:jtds:sqlserver://localhost:1433;DatabaseName=SearchGen

org.quartz.dataSource.qzDS.user = sa
org.quartz.dataSource.qzDS.password = 123456
org.quartz.dataSource.qzDS.maxConnections = 30


其中 org.quartz.threadPool.threadCount = 10表示线程池的线程数是10,所以,每次scheduler.start()时,系统都会启动10个线程,表QRTZ_FIRED_TRIGGERS动态存储启动后正在进行的或即将进行的线程的信息 

可以看到很多重复的状态为EXECUTING的线程,这样的话可能对JOB程序造成一些不可预知的印象,所以,最好在程序把QRTZ_FIRED_TRIGGERS重复的列删掉...
