RE: netmon and /etc/hosts ?

The table shows that 6000 lines of /etc/hosts is a disaster, no matter when you
read it, which is what I said.
As for the rest of it, I don't care.
My final comment is that if you have a name resolution problem on AIX 4.3.3 then
I would open a problem to AIX and have them help you solve it. This is no
longer a NetView issue and I do not believe it ever was.

we have had no such problems under a F50 with NV 5.1.x/AIX 4.2.x
only the S7A with AIX 4.3.x has this rater strange problem
>(d) consider doing more things to speed up name resolution, even if that
means

as i said before "we do have a caching-dns on the netview-box" !!!
>These are all things other people have done for a satisfactory solution.
but whats your comment on this table:
DNS | resolv-order | host-lines | time*)
--------+---------------+------------+----------
off | none | 16 | 3 min.
on | hosts,bind | 16 | 5 min.
off | none | 6000+ | 67 min.
on | hosts,bind | 6000+ | 43 min.
on | hosts,bind | 6000+ | 1 min. X)
X) this is the case if you execute
"xnmsnmpconf -clearCache -event ; ovstart netmon"
