Use localhost as hostname in listener.ora and you will never have this problem.

Jay,
Did that several months ago with our HP-MPE box. The problem was that
we
changed the IP address of the box and brought a new one online, with the old
ones original IP. Now MPE has NO idea of what a DNS server is so one has to
bury the actual IP address into things like listener.ora and tnsnames.ora.
We
had a pile of this smelly brown matter all over the place the next evening
when
the new development box ran it's nightly processes. OOPS!!!

Many of you probably know this already, but it took me by surprise (and caused no end of grief) so I thought I'd warn people.
I cloned our 8.0.4 production database onto another machine for some testing we were doing (copy of entire Oracle filesystem, copied hot backup over) and started it up with no problems.
What I didn't realize when I ran my shutdown script (which also stops the listener) was that I hadn't changed the hostname in listener.ora. It stopped the listener on the production box!
Had you asked me before this happened I wouldn't have expected it to work that way, but a number of irate users and managers testify to the fact that it does. I restarted the listener as soon as anyone thought to notify me of the problem (it says something about the processes here that it was 45 minutes after I restarted the listener that that our Help Desk contacted me me about the problem, I first heard about it from a developer).
Sigh, learn something new every day.
Hope someone out there benefits from my mistake.
