TABLE: MSC.MSC_SNAPSHOT_TASKS

Object Details

Object Name:	MSC_SNAPSHOT_TASKS
Object Type:	TABLE
Owner:	MSC
FND Design Data:	MSC.MSC_SNAPSHOT_TASKS
Subobject Name:
Status:	VALID

MSC_SNAPSHOT_TASKS stores a queue of tasks to be performed by the
Snapshot. Each entry represents a task to be performed.
The Snapshot launches several workers to perform the tasks in
parallel. Each worker scans MSC_SNAPSHOT_TASKS for the next task that
has not been started. Tasks can be dependent upon other tasks having
been completed. DEPENDENT_TASK and DEPENDENT_TASK2 store the tasks
that must be completed before a given task can begin. REQUIRES_LOCK
indicates whether or not the snapshot must have acquired locks before
this task can be started. DEPENDENCY_AGAINST is set to "Yes" if this
task has other tasks which are dependent upon it. Tasks which have
DEPENDENY_AGAINST set to "Yes" will have a higher priority than other
tasks.
START_DATE and COMPLETION_DATE store the date and time that each task
was started and completed. They also serve to indicate the status of
each tasks. A null value for START_DATE and COMPLETION_DATE indicates
that a task has not yet been started. A value in START_DATE and a
null value in COMPLETION_DATE indicates that a task is currently in
process. Values in START_DATE and COMPLETION_DATE indicates that the
task has completed.
MSC_SNAPSHOT_TASKS is populated by the Snapshot. START_DATE and
COMPLETION_DATE are updated by the Snapshot Workers and by the
Snapshot.
