Hello,
I have a problem with Hibernate with Oracle.
I must create an atomic operation of SELECT + UPDATE for a unique field increment (i can not use Oracle sequence because i have some do some check in this field). So i would like to know if I can create an atonic operation for prevent other selects of other transactions before the update. In my application I have two servers so i can not use the hibernate lock.

Thanks.
