RE: TCP/IP shutdown or crash

We shut off IP during backups (in addition to ending batch subsystems).
That way, we're guaranteed no users will access the system via TN5250,
ODBC, FTP, or anything else that might come along.  Seems easier and
faster then ending/restarting all those server tasks and we don't have
to worry about any new connection methods that come along as long as
they run the IP protocol.

Subject: TCP/IP shutdown or crash

Do you ever have a need to shutdown TCP/IP but keep the rest of the
system up (including applications) and if so, why?

Do you ever have TCP/IP crash?

I have a customer that says sometimes they need to shutdown TCP/IP and
that sometimes it crashes unexpectedly. This creates some "challenges"
for one of our applications that is TCP/IP dependent.

My stance has been that needing to shut TCP/IP down while keeping the
rest of the system up seems very unusual to me, and that having it
"crash" is unheard of and should be reported to IBM immediately.

What do you guys think?

FYI, I'm talking V5R2 here, not some old release.

Anybody?

Thanks,
