classmethod export_removeTasks(taskIDs)

This method removes the entries from TaskReplicas and Tasks with the supplied task IDs

classmethod export_removeUnlinkedReplicas()

This method removes Replicas which have no associated Tasks

classmethod export_setOldTasksAsFailed(daysOld)

Set Tasks older than “daysOld” number of days to Failed These tasks have already been retried every day for staging

classmethod export_setRequest(lfnDict, source, callbackMethod, taskID)

This method allows stage requests to be set into the StagerDB

classmethod export_setStageComplete(replicaIDs)

This method updates the status of the stage request for the supplied replica IDs

classmethod export_setTasksDone(taskIDs)

This method sets the status in the Tasks table to Done for the list of supplied task IDs

classmethod export_updateReplicaFailure(replicaFailures)

This method sets the status of the replica to failed with the supplied reason

classmethod export_updateReplicaInformation(replicaTuples)

This method sets the pfn and size for the supplied replicas

classmethod export_updateReplicaStatus(replicaIDs, newReplicaStatus)

This allows to update the status of replicas

classmethod export_updateTaskStatus(sourceID, status, successful=[], failed=[])

An example to show the usage of the callbacks.

classmethod export_wakeupOldRequests(oldRequests, retryInterval)

get only StageRequests with StageRequestSubmitTime older than 1 day AND are still not staged delete these requests reset Replicas with corresponding ReplicaIDs to Status=’New’
