Yeah, we are planning STP, but now we need to synchronize our clocks. I know
we can't automatically update time if it's deviation is higher than 5
seconds, but I SUPPOSE you can connect to the ETS. Nevertheless, now we are
doing manual synchronization. My problem is we couldn't find a manual
describing the different states and errors we can find on Sysplex Timer.

Shane proposed two of them; but I couldn't find the first one, and the
second one does not describe such errors.

By the way, we are synchronizing now, so the manuals are not urgent. I'm
only asking for those books, just in case we have any kind of problem in the
future.


Thank you very much!

Being at home at present, I'm presuming this is the manual about the
size of a (large) novel.
Paper only, from IBM only IIRC.

There are *very* specific protocol requirements which I presume you know
about. NTP won't do the job, and from memory you need to be within 5
seconds of the time source, or the synch is dropped.
I'll have a look when I get into the office tomorrow.

Of course IBM are now encouraging us to consider (real) sysplex timers
as just outdated junk what with STP being the new kid in town.
Looking after the current users as always...
