org.quartz.impl.jdbcjobstore Class JobStoreCMT

java.lang.Object
  extended by org.quartz.impl.jdbcjobstore.JobStoreSupport
      extended by org.quartz.impl.jdbcjobstore.JobStoreCMT
All Implemented Interfaces:
Constants, org.quartz.spi.JobStore
public class JobStoreCMT
extends JobStoreSupport

JobStoreCMT is meant to be used in an application-server environment that provides container-managed-transactions. No commit / rollback will be1 handled by this class.

If you need commit / rollback, use JobStoreTX instead.

Field Detail

nonManagedTxDsName

protected String nonManagedTxDsName

dontSetNonManagedTXConnectionAutoCommitFalse

protected boolean dontSetNonManagedTXConnectionAutoCommitFalse

setTxIsolationLevelReadCommitted

protected boolean setTxIsolationLevelReadCommitted
Constructor Detail

JobStoreCMT

public JobStoreCMT()
Method Detail

setNonManagedTXDataSource

public void setNonManagedTXDataSource(String nonManagedTxDsName)

Set the name of the DataSource that should be used for performing database functions.

getNonManagedTXDataSource

public String getNonManagedTXDataSource()

Get the name of the DataSource that should be used for performing database functions.

isDontSetNonManagedTXConnectionAutoCommitFalse

public boolean isDontSetNonManagedTXConnectionAutoCommitFalse()

setDontSetNonManagedTXConnectionAutoCommitFalse

public void setDontSetNonManagedTXConnectionAutoCommitFalse(boolean b)
Don't call set autocommit(false) on connections obtained from the DataSource. This can be helpfull in a few situations, such as if you have a driver that complains if it is called when it is already off.

Parameters:
b -

isTxIsolationLevelReadCommitted

public boolean isTxIsolationLevelReadCommitted()

setTxIsolationLevelReadCommitted

public void setTxIsolationLevelReadCommitted(boolean b)
Set the transaction isolation level of DB connections to sequential.

Parameters:
b -

initialize

public void initialize(org.quartz.spi.ClassLoadHelper loadHelper,
                       org.quartz.spi.SchedulerSignaler signaler)
                throws SchedulerConfigException
Description copied from class: JobStoreSupport

Called by the QuartzScheduler before the JobStore is used, in order to give it a chance to initialize.

Specified by:
initialize in interface org.quartz.spi.JobStore
Overrides:
initialize in class JobStoreSupport
Throws:
SchedulerConfigException

shutdown

public void shutdown()
Description copied from class: JobStoreSupport

Called by the QuartzScheduler to inform the JobStore that it should free up all of it's resources because the scheduler is shutting down.

Specified by:
shutdown in interface org.quartz.spi.JobStore
Overrides:
shutdown in class JobStoreSupport

getNonManagedTXConnection

protected Connection getNonManagedTXConnection()
                                        throws JobPersistenceException
Specified by:
getNonManagedTXConnection in class JobStoreSupport
Throws:
JobPersistenceException

executeInLock

protected Object executeInLock(String lockName,
                               JobStoreSupport.TransactionCallback txCallback)
                        throws JobPersistenceException
Execute the given callback having optionally acquired the given lock. Because CMT assumes that the connection is already part of a managed transaction, it does not attempt to commit or rollback the enclosing transaction.

Specified by:
executeInLock in class JobStoreSupport
Parameters:
lockName - The name of the lock to acquire, for example "TRIGGER_ACCESS". If null, then no lock is acquired, but the txCallback is still executed in a transaction.
Throws:
JobPersistenceException

JobStoreSupport.executeInNonManagedTXLock(String, TransactionCallback), JobStoreSupport.executeInLock(String, TransactionCallback), JobStoreSupport.getNonManagedTXConnection(), JobStoreSupport.getConnection()
