                                          DatabaseSystemEventNode eventNode)

Method Detail

onApplicationEvent

public void onApplicationEvent(org.springframework.context.ApplicationEvent event)

Specified by:

onApplicationEvent in interface org.springframework.context.ApplicationListener<org.springframework.context.ApplicationEvent>

stop

public void stop()

Specified by:

stop in interface ScheduledJobManager

reset

public void reset()

Description copied from interface: ScheduledJobManager

Programatically remove this node from master/active status. This should only be called during a shutdown.

Specified by:

reset in interface ScheduledJobManager

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException

getMasterNodeHeartbeatIntervalSeconds

public long getMasterNodeHeartbeatIntervalSeconds()

Description copied from interface: ScheduledJobManager

The amount of time between each heartbeat update for this node, if active. Default is 10.

Specified by:

getMasterNodeHeartbeatIntervalSeconds in interface ScheduledJobManager

Returns:

setMasterNodeHeartbeatIntervalSeconds

public void setMasterNodeHeartbeatIntervalSeconds(long masterNodeHeartbeatIntervalSeconds)

Specified by:

setMasterNodeHeartbeatIntervalSeconds in interface ScheduledJobManager

getNodePurgeThresholdSeconds

@ManagedAttribute(description="Number of seconds a node can miss heartbeat detection before determining that the node has become defunct.",
                  currencyTimeLimit=15)
public long getNodePurgeThresholdSeconds()

Description copied from interface: ScheduledJobManager

The amount of time an active master is allowed to not update it's heartbeat status before being a purge candidate. The default is 60.

Specified by:

getNodePurgeThresholdSeconds in interface ScheduledJobManager

Returns:

setNodePurgeThresholdSeconds

@ManagedAttribute(description="Number of seconds a node can miss heartbeat detection before determining that the node has become defunct.",
                  currencyTimeLimit=15)
public void setNodePurgeThresholdSeconds(long nodePurgeThresholdSeconds)

Specified by:

setNodePurgeThresholdSeconds in interface ScheduledJobManager

getNodePurgeIntervalSeconds

public long getNodePurgeIntervalSeconds()

Description copied from interface: ScheduledJobManager

The amount of time between each master purge attempt. The default is 30.

Specified by:

getNodePurgeIntervalSeconds in interface ScheduledJobManager

Returns:

setNodePurgeIntervalSeconds

public void setNodePurgeIntervalSeconds(long nodePurgeIntervalSeconds)

Specified by:

setNodePurgeIntervalSeconds in interface ScheduledJobManager

isPause

@ManagedAttribute(description="Whether or not job processing is currently paused.",
                  currencyTimeLimit=15)
public boolean isPause()

Description copied from interface: ScheduledJobManager

Whether this node is paused. A paused manager will not update job status and the internal Quartz instances are also paused, resulting in registered jobs not firing.

Specified by:

isPause in interface ScheduledJobManager

Returns:

setPause

@ManagedAttribute(description="Whether or not job processing is currently paused.",
                  currencyTimeLimit=15)
public void setPause(boolean pause)

Specified by:

setPause in interface ScheduledJobManager

The number of Quartz thread available for jobs execution. The default is 20.

Specified by:

getJobThreadPoolCount in interface ScheduledJobManager

Returns:

setJobThreadPoolCount

Specified by:

setJobThreadPoolCount in interface ScheduledJobManager

getEventFactories

public Map<String,SystemEventFactory> getEventFactories()

Description copied from interface: ScheduledJobManager

Retrieve the list of factories responsible for creating SystemEvent instances upon job execution. Jobs, when fired, result in events. Event are then consumed, which is the end goal.

Specified by:

getEventFactories in interface ScheduledJobManager

Returns:

setEventFactories

public void setEventFactories(Map<String,SystemEventFactory> eventFactories)

Specified by:

setEventFactories in interface ScheduledJobManager

isMaster

Specified by:

isMaster in interface ScheduledJobManager

isMaster

public boolean isMaster(boolean confirmStillMasterNode)

Description copied from interface: ScheduledJobManager

Verifies that the current eventNode is the masterNode by retrieving the node designated as master and double checking. If the node was marked as the master and confirmed to not be the master, the master is reset via the setMaster() method.

Specified by:

isMaster in interface ScheduledJobManager

Returns:

setMaster

public void setMaster(boolean master)

Specified by:

setMaster in interface ScheduledJobManager

getScheduler

public org.quartz.Scheduler getScheduler()

Description copied from interface: ScheduledJobManager

Retrieve the internal Quartz scheduler instance.

Specified by:

getScheduler in interface ScheduledJobManager

Returns:

getEventNode

public DatabaseSystemEventNode getEventNode()

Description copied from interface: ScheduledJobManager

This ScheduledJobManager instance is also a node in the cluster. Retrieve the associated DatabaseSystemEventNode instance.

Specified by:

getEventNode in interface ScheduledJobManager

Returns:

setEventNode

public void setEventNode(DatabaseSystemEventNode eventNode)

Specified by:

setEventNode in interface ScheduledJobManager

buildScheduler

protected void buildScheduler()
                       throws IOException,
                              org.quartz.SchedulerException
