Hi there
I am creating a program that needs to increment a counter. Typically a
serial number has to be incremented every time I create a certificate.
The problem is to handle concurrent access. Fundamentally I need to 1/
read the counter 2/ increment it. Therefore no one must be provided
access to the counter during these two operations.
Therefore I need to set a lock before the read operation and release it
after the update. Is there a way to do this with OL ? I am conscious of
the ldapmodify features thanks to Clement, however, this will not lock
the read.
Thks in adv.
