For my company, for example, it is run entirely through our web site -- there's no shrink-wrapped product, no magazines, etc. Therefore, as a smaller company ourselves, we made the business decision that we would lose money beyond recovery if our site was down for an extended period of time. As such, the thousands of dollars we paid to be in a clustered environment (two physical servers each running full versions of JRun with CF Enterprise deployed in each behind a BigIP load balancer) is a drop in the bucket and a no-brainer. That being said, the situation is might be entirely different for you. In Adam's case, I believe he works for the US State Department. That's not one of my government agencies that I'd want to hear has constant downtime! (And $10K in the context of the State Department's budget is nothing anyway.) As others have noted, there are ways to achieve high availability without buying top shelf hardware and Enterprise versions of ColdFusion. Personally, I'd start by looking at your code, and, in particular, any potentially long running queries to see if that's what's causing your spikes. Make sure you're using the recently released JDBC driver upgrades and that they're properly installed. Turn on the "log long running requests" option in the CF Admin and set the threshold to a value right at what you think the longest page response should be. I think what you'll find is that most issues are with the codebase and not the CF server product itself. I've consulted on numerous engagements where the client was blaming the hardware, but there was zero effort to cache anything and their code was constantly making query calls to pull back 10,000 records just to get a record count! All of the above being said, there is great value in failover availability. Others have already chimed in with relatively cheap solutions you could try out if your code analysis is fully optimized.

Re: 1 ColdFusion Failover costs 8-10x more than a standalone server!
Sticky sessions are where a load balancer is smart enough to send all requests from a given user session to a single server in the cluster. I.e. instead of delegating each individual request to one of the servers, it keeps track of which requests belong to each session, and ensure that a single session always goes to the same server. You don't have to risk losing sessions when you fail over; there are two ways to avoid it. 1) Use CF Enterprise, which includes session replication so all servers can process requests from any session. Still a good idea to use sticky session, because replication isn't instantaneous. 2) don't use session storage, instead use client variables (or something like it), where the data is stored in a shared location (the DB), instead of in memory. That gives you the ability to have any request go to any server and that server will be able to get the needed data from the DB. This obviates the need for sticky sessions, though you can have a lot of weird concurrency issues, because of non-atomic operations on the client variables. If you're considering this mechanism, I'd highly recommend NOT using client variables, and instead using something home grown that addresses the concurrency issues. We use the latter approach, because we need to have perfect uptime (aside from occasional scheduled maintenance), with no session loss if something breaks. The former option is far more performant, but it's still possible to have session-related issues on a failover. The latter also doesn't require CF Enterprise, which saved us almost $20,000 in CF licensing (though we poured most of that back into developing a custom client variables implementation). cheers, barneyb On 8/30/05, Dustin M Snell [Network Automation] <[EMAIL PROTECTED]> wrote: > Thanks for all the answers so far, > > Hmm - so it may be possible after all if I am willing to loose the sessions? > What are sticky sessions? > > -Dustin Snell > Network Automation, Inc > > -- Barney Boisvert [EMAIL PROTECTED] 360.319.6145 http://www.barneyb.com/ Got Gmail?

You don't lose sessions - you only lose CLUSTERED sessions. "Sticky Sessions" is just a term which implies that once a visitor hits a server they'll STAY on that server - no matter what the load. So any server can use sessions all it wants: but if it crashes that session is lost. Clustered Sessions shares the session information across multiple servers in the cluster. In this scenario the visitor is not "stuck" to a server but can hit any server in the cluster and get their data. There are limitations to the type of data which can be stored in a clustered session and the process involves more than a little overhead... so even when it's possible some people choose not to use them.

You don't need enterprise to do failover or basic load-balancing (but you do need something to do that). You'd need it for session sharing and the like... but you can get around that as well (as long as your external solution can "pin" a visitor to a specific box you're set). > So the formula is: > > 1 server solution = $695-$1200 (depending on upgrade or new) > 1 redundant server solution (2 servers with same content) = $10,000+ > > Does this make sense to everyone here? Yes. For what it's worth that's about $90,000 cheaper than a similar WebSphere configuration and less than half of most other "enterprise" options. You might be able to stick with CFML and go even cheaper by adopting BlueDragon (if your app will run on it).

RE: 1 ColdFusion Failover costs 8-10x more than a standalone server!
If you want a complete, enterprise-ready solution, you will need CF Enterprise. This will give you almost no noticable problem if a server goes down. Otherwise, you can use CF Standard on two separate servers. If you use the OS's load balancing and failover such as Windows' NLB, and use single affinity (sticky sessions) you shouldn't have a problem. The sticky sessions will keep your users from automatically switching from one CF server to the other and losing their sessions. Of course, if a server goes down hard, the users will be shunted to the other server which will require their session to be re-created. This could simply mean a slight delay while their session variables are being set, or they could be asked to log in to the application again. If we are to pursue redundancy, this would be our solution. From what I remember, Roland Collins uses this solution as well. You might search back through this list. I think it was about a year back.

RE: 1 ColdFusion Failover costs 8-10x more than a standalone server!
You can do loadbalancing without using the enterprise version of CF (I'm assuming you're on standard now, since you're saying that the cost of the single server is $1200... You won't get session replication, but if you're willing to lose sessions when the server goes down, and set up sticky sessions for the rest of the time, you'll be fine... We are currently going from one server (standard) to 2 servers (enterprise). I'm currently setting up the cluster. We got a good deal from HostMySite for a dedicated loadbalancer (which I believe you can use to handle sticky sessions). You still won't get session replication without enterprise, but if you don't care about people losing their sessions when one of the servers goes down, you'll be fine. -Original Message- From: Dustin M Snell [Network Automation] [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 30, 2005 3:01 PM To: CF-Talk Subject: 1 ColdFusion Failover costs 8-10x more than a standalone server!

Maybe look into paying for support and have a MM engineer troubleshoot why the server's hanging. Will definitely cost you some bucks but the alternative will also cost you...

For example: JRUN will go completely haywire and take all the CPU and Virtual Memory on the system about once every 2 days, sometimes multiple times a day. We haven't been able to figure out why. For this and other reasons (such as the occasional upgrade), we have decided that a 2 server cluster would be a good idea so at least we could get some redundancy. We don't need load balancing really, just failover but it looks like you usually get both no matter what you do. Unfortunately, after calling Macromedia I have found that the only way to do this is to buy 2 licenses of ColdFusion Enterprise. So basically this will entail approximately a $10k+ investment in just Coldfusion licenses (not to mention hardware etc), which works out to about 8 times our original investment for the existing license, just to get some redundancy! So the formula is: 1 server solution = $695-$1200 (depending on upgrade or new) 1 redundant server solution (2 servers with same content) = $10,000+ Does this make sense to everyone here? For the love of God can someone tell me please: is there another way to get some redundancy? -Dustin Snell Network Automation, Inc ~| Logware (www.logware.us): a new and convenient web-based time tracking application.
