Why not set a task lock such as BookingTasks to allow one process to
perform this task at a time? (Or is that an issue?)
When I say task lock, I mean a lock on a scratch record that does not
exist.

Subject: [U2] UV:basic readu lock promote to filelock when locktable is
full!!
Hello U2Group,
I'm in a trouble with size of the lock table and transaction,
Here is my situation :
- I run a basic program which analyze a order composed of piece
to manufacture. These analyze is done within a TRANSACTION.
- Each piece analyzed result on a set of tasks
- Each task record is store individually into a file OrderTasks
(+ OrderTasksStatusHistory ~ updated via triggers on OrderTasks.)
- For a piece we get +- 20 tasks.
Then when we analyze a big order which contain more than 150 pieces the
transaction contain at least (150x20x2) 6000 records updates .
Ok, my uvconfig settings about locks mngr are
FSEMNUM= 23
GSEMNUM= 499
FLTABSZ= 11
GLTABSZ= 113
RLTABSZ= 79
RLOWNER= 75
Usually, it works good without problem.
But sometime, I get a very large order with 200 pieces and then the
transaction's locks request exceed the capacity of the locks table (+-
9000)
I known the solution reside into a escalate the readu lock to a filelock
for my OrderTask /OrderTaskStatusHistory files but ...
Here is my question :
On a isolate subroutine which perform a readu can I check the number of
recordlock already acquired by me ?
- 1 - on a central subr to handle READU
- 2 - on a trigger subr
Any idea is welcome
Regards.
Manu
