That's actually a relief. At first I was
told it was 5.1, and I was seriously doubting my sanity because I never noticed
any problem whatsoever. Thanks for the response.

Yup. Please see my append "Problem
found in 5.1.1". It was discovered on
Friday, APAR IX88166 was
created, and some of our best engineers worked
over the weekend to
fix it. The fix was applied to our systems and the
reporting
customer system yesterday, and the results certified today.
The gist
of it is that status propagation will fail on some routers (and
only on
routers) when their interfaces change status. They may stay
green
even when their interfaces go red, or they may stay blue if
unmanaged and
re-managed. That is a horrible bug, I know.
That's why we worked so hard
to fix it as soon as it was
discovered.
Only those customers who have already installed 5.1.1 are
affected.
Shipment of 5.1.1 has been halted until a new copy can be used
to replace
it in Software Distribution.
More details are in the
"Problem found in 5.1.1" append I just sent.
On behalf of
the entire Support organization, my apologies. We have
already
begun meetings to discuss how to prevent this kind of thing (a bug
of
this magnitude going undetected in the Verification process)
happening
again.

Subject: IX88166???
I've
heard it through the grapevine that IX88166 has just been released,
and
that all NetView customers may be impacted. This fix
supposedly
corrects NetView's status propogation. Also, there are
only two ways to
fix the system up after applying the code fixes, either
restart your
database from scratch, or manually hit each and every device
and change the
status propogation from Compound, to symbol, then back to
compound again.
Needless to say this does not please me at all.
I have a very large
database with a very large number of objects, and I
have noticed no
problems in this arena. I don't want to jump unless
I am 100 percent sure
that there is a problem.
Can someone from
Tivoli confirn or deny this problem and give us more
details about how to
confirm its impact on our systems?
Thanks;
