isLockOnInsert

public boolean isLockOnInsert()

setLockOnInsert

public void setLockOnInsert(boolean lockOnInsert)
Whether or not to obtain locks when inserting new jobs/triggers.

Defaults to true, which is safest. Some databases (such as MS SQLServer) seem to require this to avoid deadlocks under high load, while others seem to do fine without. Settings this to false means isolation guarantees between job scheduling and trigger acquisition are entirely enforced by the database. Depending on the database and it's configuration this may cause unusual scheduling behaviors.

Setting this property to false will provide a significant performance increase during the addition of new jobs and triggers.

Parameters:
lockOnInsert - whether locking should be used when inserting new jobs/triggers

getMisfireThreshold

public long getMisfireThreshold()

setMisfireThreshold

public void setMisfireThreshold(long misfireThreshold)
The the number of milliseconds by which a trigger must have missed its next-fire-time, in order for it to be considered "misfired" and thus have its misfire instruction applied.

Parameters:
misfireThreshold - the misfire threshold to use, in millis

isDontSetAutoCommitFalse

public boolean isDontSetAutoCommitFalse()

setDontSetAutoCommitFalse

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

Parameters:
b - whether or not autocommit should be set to false on db connections

isTxIsolationLevelSerializable

public boolean isTxIsolationLevelSerializable()

setTxIsolationLevelSerializable

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

Parameters:
b - whether isolation level should be set to sequential.

isAcquireTriggersWithinLock

public boolean isAcquireTriggersWithinLock()
Whether or not the query and update to acquire a Trigger for firing should be performed after obtaining an explicit DB lock (to avoid possible race conditions on the trigger's db row). This is the behavior prior to Quartz 1.6.3, but is considered unnecessary for most databases (due to the nature of the SQL update that is performed), and therefore a superfluous performance hit.


setAcquireTriggersWithinLock

public void setAcquireTriggersWithinLock(boolean acquireTriggersWithinLock)
Whether or not the query and update to acquire a Trigger for firing should be performed after obtaining an explicit DB lock. This is the behavior prior to Quartz 1.6.3, but is considered unnecessary for most databases, and therefore a superfluous performance hit. However, if batch acquisition is used, it is important for this behavior to be used for all dbs.

cleanupConnection

protected void cleanupConnection(Connection conn)

Cleanup the given database connection. This means restoring any modified auto commit or transaction isolation connection attributes, and then closing the underlying connection.

See Also:
closeConnection(Connection)

closeConnection

protected void closeConnection(Connection conn)
Closes the supplied Connection.

Ignores a null Connection. Any exception thrown trying to close the Connection is logged and ignored.

Parameters:
conn - The Connection to close (Optional).

rollbackConnection

protected void rollbackConnection(Connection conn)
Rollback the supplied connection.

Logs any SQLException it gets trying to rollback, but will not propogate the exception lest it mask the exception that caused the caller to need to rollback in the first place.

Parameters:
conn - (Optional)

commitConnection

protected void commitConnection(Connection conn)
                         throws JobPersistenceException
Commit the supplied connection

Parameters:
conn - (Optional)
Throws:
JobPersistenceException - thrown if a SQLException occurs when the connection is committed

executeWithoutLock

public Object executeWithoutLock(JobStoreSupport.TransactionCallback txCallback)

Execute the given callback in a transaction. Depending on the JobStore, the surrounding transaction may be assumed to be already present (managed).

This method just forwards to executeInLock() with a null lockName.

Throws:
JobPersistenceException

executeInLock(String, TransactionCallback)

executeInLock

protected void executeInLock(String lockName,

                      throws JobPersistenceException
Execute the given callback having acquired the given lock. Depending on the JobStore, the surrounding transaction may be assumed to be already present (managed). This version is just a handy wrapper around executeInLock that doesn't require a return value.

Parameters:
lockName - The name of the lock to acquire, for example "TRIGGER_ACCESS". If null, then no lock is acquired, but the lockCallback is still executed in a transaction.
Throws:
JobPersistenceException
See Also:
executeInLock(String, TransactionCallback)

executeInLock

protected abstract Object executeInLock(String lockName,
                                        JobStoreSupport.TransactionCallback txCallback)
                                 throws JobPersistenceException
Execute the given callback having acquired the given lock. Depending on the JobStore, the surrounding transaction may be assumed to be already present (managed).

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

                                  throws JobPersistenceException
Execute the given callback having optionally acquired the given lock. This uses the non-managed transaction connection. This version is just a handy wrapper around executeInNonManagedTXLock that doesn't require a return value.

Parameters:
lockName - The name of the lock to acquire, for example "TRIGGER_ACCESS". If null, then no lock is acquired, but the lockCallback is still executed in a non-managed transaction.
Throws:
JobPersistenceException

executeInNonManagedTXLock(String, TransactionCallback)

executeInNonManagedTXLock

protected Object executeInNonManagedTXLock(String lockName,

                                    throws JobPersistenceException
Execute the given callback having optionally acquired the given lock. This uses the non-managed transaction connection.

Parameters:
lockName - The name of the lock to acquire, for example "TRIGGER_ACCESS". If null, then no lock is acquired, but the lockCallback is still executed in a non-managed transaction.
Throws:
JobPersistenceException
