This is why I suggested we set aside some range of numbers that should not be used. Doing so would allow adding a better-managed numbering/naming scheme in the future.
the whole point about advisory locks is that the provided lock space is unmanaged. for example, in the ISAM system I wrote which hooked into the acucobol virtual file system interface, I used a global sequence for row level pessimistic locking but reserved the 48th bit for table level locks. This system was extremely effective. on the current system I'm working on I use them to lock sequence oid's plus a high bit indicator for what i am doing. in short, advisory locks are application-defined in concept. merlin ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
