Vic,
Yes, I do get a deadly embrace or deadlock, as the
row locks on the table multiply when they occur,
holding up connections in the connection pool,
eventually consuming all connections, and then all
hell breaks loose.
Were you referring to synchronizing
order.So, there
is no question of cyclic issue. The issue here is
concurrent users may update the same rows of the
concerned table, and at some point, the database
cannot handle the updates, depending on the number of
users.
Do you think using a stored procedure for the
transaction will help
