Quiet_Point
Noquiet_Point
Allows you to specify that a database move operation is to occur
either immediately or when a quiet point for database activity
occurs. A quiet point is defined as a point where no active
update transactions are in progress in the database.
When you specify the Noquiet_Point qualifier, Oracle RMU proceeds
with the move operation as soon as the RMU Move_Area command is
issued, regardless of any update transaction activity in progress
in the database. Because Oracle RMU must acquire exclusive locks
on the physical and logical areas for the areas being moved,
the move operation fails if there are any active transactions
with exclusive locks on storage areas that are being moved.
However, once Oracle RMU has successfully acquired all the needed
concurrent-read storage area locks, it should not encounter any
further lock conflicts. If a transaction is started that causes
Oracle Rdb to request exclusive locks on the areas that are in
the process of being moved, that transaction either waits or
gets a lock conflict error, but the move area operation continues
unaffected.
If you intend to use the Noquiet_Point qualifier with a move
procedure that previously specified the Quiet_Point qualifier
(or did not specify either the Quiet_Point or the Noquiet_Point
qualifier), you should examine any applications that execute
concurrently with the move operation. You might need to modify
your applications or your move procedure to handle the lock
conflicts that can occur when you specify the Noquiet_Point
qualifier.
When you specify the Quiet_Point qualifier, the move operation
begins when a quiet point is reached.
The default is Quiet_Point.
