Here's a new article from Macromedia on configuring Verity to run on a seperate server than that which hosts the ColdFusion MX 7 server, as a distributed Verity configuration.
This is especially useful for running ColdFusion MX 7.0 on Mac OSX since Verity is currently not supported on that platform, as noted in a previous blog entry.
Although didn't help me with my quest to find out if two cf's can access the same verity collection stored on a remote disk :)

A ColdFusion MX 7 Verity K2 Server can only be configured to listen to 1 ColdFusion server at a time, and is configurable if you want to change the server that it points to. I'll try to dig up information that shows how to do it. The hostname of the CF server which K2 should listen for is set during the ColdFusion SearchService installation, so worst case to change the host that K2 listens to is to reinstall it and enter a different host name during the installation of the Search Service.

What i mean is two CF Servers using a SAN for storage and storing the verity collection on the SAN and then having the two CF servers using the same collection. We were able to do it with cf6.1 on *NIX but now I get a really unhelpful error message when i try it in our new windows environment.

Well that's certainly not a supported option. I'd guess there's a high risk of collisions should both server try to index/refresh the collection.

I'm sure you thought of clever configurations, but just as an idea, you could have one CFMX 7 server running with K2 and all collections are maintained there. Then expose Verity searches as a webservice or other remote invocation type. An array of matching records could be returned where each array index contains a structure with the various record metadata such as URL, size, title, etc...

me again :)
the article says,
"On the ColdFusion MX 7 server, open the ColdFusion MX Administrator. Select the Verity K2 Server link in the left pane. Enter the name or IP address of the server that the Verity search server (K2) is running on."
That option is only in Enterprise - I don't see it in CF Standard...Am having a silly moment?

John, you're right about that. Standard does not have the link for K2 Server, so the article can only be followed by those with Enterprise edition.
I notified the author and he said that since the download page for the Verity K2 installer kit was just changed to accept a Standard licence in addtion to an Enterprise license, he made the assumption his article would work for both editions.
The author will look into it and update the article. Thanks for letting me know!

I just want to correct a comment I made earlier.
I said "A ColdFusion MX 7 Verity K2 Server can only be configured to listen to 1 ColdFusion server at a time", but I meant that a ColdFusion MX 7 Verity K2 Server can only be configured to listen to 1 IP address at a time, where that IP address can have multiple instances of ColdFusion Servers.
The actual Verity collections are stored on the server where Verity is installed, not on the server hosting ColdFusion, so in this "distributed" Verity config, there's no potential for collection collisions due to multiple concurrent access.

Readers of this blog entry will be interested in a post by Ben Forta today on the Verity licensing restrictions regarding how many ColdFusion servers can connect to a single K2 instance:
Is it possible to move from a local verity installation to a remote one. I had verity working locally but now that I have installed it remotely I am unable to connect to the remote verity service. Do you have to uninstall the local version. The message I get in the adinistrator is that it cannot connect to the service.
