Hi all, I have a question that one of you with experience with CF Enterprise will probably know off the top of your head. Although I've worked in CF for 7 years now, I've only ever used the Standard edition, and I am unsure about exactly how clustering works in the Enterprise edition. In a clustering/load-balancing/fail-over environment, how are the various variable scopes handled? Do you have to do something special to make session variables available? What about application and server variables? They're all stored in RAM, so I thought they must be limited to one machine only, and that requests should come in to that same machine. I even thought I saw a post at one time where you could download a particular script or patch or something that shares session variables to the other computers in the cluster - is that all necessary, and if so, does it work? Hopefully you can see what I mean. I'm just trying to see what code changes might be required to our programs when we switch from CFMX 6.1 over to CF Enterprise 8. If you think you have any answers for me about this or other topics regarding upgrade problems that you can put into just a couple of sentences, or can point me to a good forum thread that covers this, then please let me know. TIA Steven Van Gemert P.S. I have searched forum messages for this answer, and have been unsuccessful. I'm hoping to get something from you guys I can tell my client. :) |
