OptimisticLockException
Hello,
so i try to test the geronimo 2.0.2 server how it handles concurrent delete
requests. i
start quite low with 5 concurrent users trying to delete some values from
the database. the problem is that i keep getting the error mentioned in the
subject. the more concurrent users i schedule, the more errors i get until
about 30 concurrent users the performance levels off quite low. the thing i
do in my code is removing a persistent entity:
// em.lock(director,LockModeType.WRITE); //optimistic lock
exception??????
em.remove(director);
//em.flush(); //because of optimistic lock
exception
deleted++;
i also tried with the help of the commented out lines, but without a
significant performance increase, here is the error log, maybe someone could
help, THANK YOU!

Re: OptimisticLockException
Posted by Dain Sundstrom <da...@iq80.com>.
This is one of the more confusing parts of the JPA spec. Although the
API looks like you should be getting a pessimistic write lock (select
for update in oracle) when you call that method, you actually only get
an optimistic lock according to the spec. In order to get a
pessimistic lock, you need to turn on the OpenJPA pessimistic lock
code by adding this flag to the persistence unit:
openjpa.LockManager=pessimistic
This only works if you are using a database that supports pessimistic
lock. The default database in OpenEJB hsqldb doesn't so you'll have
to use something like Derby, H2, Oracle, mySql or DB2.
