If you are running unix, you could have an email alias run a script
that triggers the phantom, then to start the phantom, just have
unix send an email to that address.

Tom,
Sounds like a classic application for sockets. Inter process communications.
Phantom 1 opens a server socket on a known port/IP and waits on a
blocked read for something (like a process name to run for example).
Process 2 opens a socket on the known port/ip and writes the name of the

If this is the approach you go for, I would recommend that you use a resource
lock, rather than a record lock (no need to open file etc etc)... Resource
locks are set system wide, so are not limited to a single account / file /
record, and are accessed with the LOCK/UNLOCK UniBasic commands...
Can you glean anything from SYSTEM(9001)?

Thank you for all the responses.
I should have stated that we are a UniVerse shop.
I did play with the lock/unlock but the only process that can modify the lock
is the one that set it. Also, I could not get the process to wait on the lock.
From the playing I did, lock/unlock seems very

Tom, can you elaborate when you say the only process that can modify the
lock is the one that set it. Isn't that exactly how a semaphore is
supposed to work? Both processes should be able to set the lock but only
one can have it at any moment in time. Or am I missing the point?

I agree. I wrote two little programs.
LOCK.TEST1
0001 LOCK 60 ELSE CRT '60 LOCKED'
0002 CRT 'UNLOCKED'
LOCK.TEST2
0001 UNLOCK 60
0002 CRT '60 WAS UNLOCKED'
LOCK.TEST1 locked 60 displayed unlocked.
LOCK.TEST2 generated the error ' Program LOCK.TEST2: Line 1, Lock 60 not

Yep ... sure miss sem$wait sem$notify. You could accomplish the same
thing with a simple socket-based protocol. The main process could listen on
a socket and wait for any of the sub-processes to connect and send a message
via the socket.

One example of what I'm trying to do is develop a record lock manager (for the
lack of a better description) for non-persistent connections. I need the lock
manager to wakeup when there is a request for a readu/write/delete. The all

A point to remember if using sockets (on UniVerse) is that your phantom will
become an iphantom, and thus consume a license.

Tom,
I don't think that 'maintaining a lock manager' is necessarily a good
solution to non-persistent connections.
A more conventional approach is for each connection to maintain the
state of the record(s) it was going to modify - i.e. a 'before image'.
Then, when it's time to apply the

I do understand the concern, and the concept of optimistic locking. Our
application will have session timeout logic, so we can clean-up any locks. We
will be developing tools to keep the control records cleaned up. Our problem
is that we cannot use optimistic locking for the application.

Reasonably certain you can also specify output to file.
Output To Screen/Printer/File (S/P/F) ?
Enter option: S creen, P rinter or F ile (xxUSERTEXT $FILEport.page).

Convert xxUSERTEXT to a dir type file (aka UV type 19) and you should be
able to pick up the parts using ftp,

If you turn on the errlog file in /u1/uv you may get a message in there for an
