64 bit ColdFusion on 32 bit IIS

Lets say I have a 64 bit install of CF on Win 2003/IIS 6. If I move the IIS to 32 bit mode, will I lose the advantage of 64 bit CF? Do I have to make any changes to the CF connectors? Thanks -- Michael Dinowitz

You going to run the Enterprise version, and is ColdFusion V8 or V9? Lets say I have a 64 bit install of CF on Win 2003/IIS 6. If I move the IIS to 32 bit mode, will I lose the advantage of 64 bit CF? Do I have to make any changes to the CF connectors? Thanks -- Michael Dinowitz

>>> If I move the IIS to 32 bit mode, will I lose the advantage of 64 bit CF? No, CF couldn't care less what's serving it. The 64 bit advantage comes from the underlying JVM it's using. As long as it's 64 bit hardware, a 64 bit OS and a 64 bit JVM, then the 64 bit version of CF9 will work as expected. >>>Do I have to make any changes to the CF connectors? Not entirely sure, but I think you'll need to completely un-install IIS to make this change. If so, then yes you would need to update the connectors. You should be able to just run the connector.bat file... But I'm not sure, I've never tried to run the 32 bit IIS on a 64 bit windows install.

You simply set the application pool to 32-bit. You will need to reinstall connectors, though.

No, CF will still do its 64-bit thing. But I'm not sure whether the out-of-the-box connectors will work with a 32-bit application pool. Maybe you can ditch Ionic's ISAPI rewriter instead? There may be a 64-bit alternative out there.

Is it at all possible to upgrade to Win2K8? If so, you could use the URL Rewriting in IIS7 and dump Ionic. It has worked out quite well for us thus far. We had to tweak the rules some (we were using Helicon before) but since then has been solid. Otherwise, I'd suggest looking at Apache and Mod-Rewrite.

Also with IIS6 your locked in to using 32bit or 64bit application pools across the board (its all shared) but with II7 you can mix and match the application pools where some run 32bit and others run 64bit. ________________________________ From: Judah McAuley <judah@wiredotter.com> To: cf-talk <cf-talk@houseoffusion.com> Sent: Mon, March 15, 2010 10:58:18 AM Subject: Re: 64 bit CF on 32 bit IIS Is it at all possible to upgrade to Win2K8?

To reiterate what others have said in a different way, no, you will not loose CF's 64-bit functionality. The Application Pool's settings only effect the IIS connector, which matters little. The one possible hang-up would be if the connectors were compiled for 32-bit support. If they weren't, then you'll probably get an error because IIS can't run the connector in 32-bit mode.
