Hello, PH>If you do use BerkeleyDB, I suggest you just use the simple PH>database-level lock. Otherwise, you have to think about deadlocks and I PH>found the deadlock daemon that comes with it kind of difficult to use.
Later versions of BerkeleyDB have a row-level lock available which works pretty transparently. However, this works using mmap() so it won't work if your BerkeleyDB file(s) is/are mounted via NFS. flock()'s scalability over NFS using lockd under Solaris is also questionable so many people end up implementing their own database-level lock using, say, atomic moves. It's an icky world out there.
