You are completely correct since optimistic concurrency control is based on
timestamping and not locking. So, if you do not acquire locks, you can not
create
a dealock.

I blame the server when it's vendor promises optimistic concurrency and
doesn't
really provide it. You may be having problems with my statement because you
do
not agree with the statement that deadlocks cannot occur with optimistic
concurrency control. I don't care what actual products do that claim
optimistic
concurrency, if they deadlock then the claims are false.
