Yes.
A multi-server install (not a clustered) of CF could well
have one instance
of JRUN.EXE running for each CF instance. There's usually at
least two: one
for the initial CF instance, and one for the JMC. You can
switch the JMC
one off (starting it on the off-chance you need it, which is
almost never).
> The first instance is usually very high (ex. 450 MB)
while the other
That's not especially high for a CF app server. We generally
allocate the
max 1.3GB (on Windows) to the JVM that each CF instance is
using.
> 512 MB RAM
OK, that's not even enough RAM for a PC workstation these
days, let alone a
server! W2k3 itself needs around a minimum of 400MB to run.
The default
install of CF will want another 512MB.
I would not run a desktop PC on less than 2GB RAM these days.
And make
that 4GB for a server. A low-spec'ed one.
