I have similar experience and make similar recommendations. There are
all sorts of detailed ways in which the Windows product behaves less
well than the Unix product, even though the marketing bullets are the same.
One area where I had particular pain was in the management of a
hierarchy of NetViews with a Manager of Managers NetView on AIX and sub
NetViews on NT. In addition to the data collection problems you found,
many of the general housekeeping routines I use on Unix NetView are
inappropriate / harder / unimplementable on Windows.
So, like Karl, I would ONLY recommend NetView on Windows where thers is
NO Unix experience, the installation is small, single NetView, and data
collection was not required. This isn't necessarily a fundamental
problem with NetView per se - many of the limitations are due to
underlying Operating System limitations.
Whilst on the soap box........
Please IBM - can we have the Linux NetView upgraded to support all the
features of AIX and Solaris - RDBMS, MLM Configuration, APM, ........
Cheers,
Jane
