PMBlockUpdate can be used for performance tuning of Image Statements when archiving rendered statements back into OnBase.
A value of zero (0) disables disk group locking.
A value of one (1) enables disk group locking. Image Statements will lock every disk group used for archiving rendered statements while the entire rendering job is process. Nobody else can have write access to the disk group while it is lock. However, Image Statements would archive rendered statements much faster.
