We run both CF and Spectra on a cluster of Solaris machine...

Licenses are needed for all machines...

There are pitfalls in doing this, especially in CFA_page and CFA_container,
these tags look for Entries (when registering new objects) in the Sitemodel
in the server scope, if they find no entry, then they create a new page or
container, However the problem arises when one cluster machine creates a new
object and only updates IT'S server vars, the next machine to hit the same
code will create its OWN new object, then they both look at different
objects, until the machines are rebooted and get all confused when finding
two objects in the database.....

To get round this problems you either refresh the sitemodel before each
creation of a new page or container...
or
Stop the tags when they attempt to create a new object and require an
override (in the URL) to create the new object (and another URL param to
force the server to refresh its server scope)

If you want to see code, then just ask

Mr Loke,

You will need to install CF, Spectra on both and implement some type of load
balancing.

Also there are considerations as to the CF application you are
coding/running as well.

I'm quite sure that both CF and Spectra licences are per machine. In which
case you need licences for each installation you do.

I'm sure someone will be much more informative than this, but for the time
being..

Dear folks

One of my clients who uses Spectra intends to improve site performance by
clustering ColdFusion servers. They intend to increase the number of boxes
from 1 to 2.

If we were to do this, do we have to install ColdFusion AND Spectra on both
boxes in order to work? In this case, how many licenses should we purchase?

Thanks for any help.
