node in a cluster, and <A
HREF="additionalutils.html#LAUNCHCLUSTERS"
>Section 6.1.4</A

those configuration files.</P
><P
> This approach is preferable to elder <SPAN

systems in that you can very precisely <SPAN
CLASS="QUOTE"
>"nail down,"</SPAN
> in
each config file, the exact desired configuration for each node, and
not need to be concerned with what options the watchdog script may or
may not give you. This is particularly important if you are using
<A
HREF="logshipping.html"
> log shipping </A

the <TT

thereby your whole day.</P
