Re: Slow (sorta) site issues - Ideas?
In a shared environment you have to ask yourself to what degree optimizing the performance of your site's code is ultimately going to improve your web site's performance. Even if you were to increase performance 10-fold it's unlikely you'll see anywhere near that performance gain if there are 200 other web sites on the same server. It will of course depend on what those other sites are doing when yours is busy, but you have so little control over this that all you can do is cross your fingers. If you knew that your site was going to use a significant percentage of the server's resources then it may be worth the effort. If you don't know this then it's just a crap-shoot. - Original Message - From: Jim Davis [EMAIL PROTECTED] To: CF-Talk cf-talk@houseoffusion.com Sent: Monday, December 27, 2004 8:38 PM Subject: RE: Slow (sorta) site issues - Ideas? -Original Message- From: gabriel l smallman [mailto:[EMAIL PROTECTED] Sent: Monday, December 27, 2004 8:27 PM To: CF-Talk Subject: RE: Slow (sorta) site issues - Ideas? Couple of thoughts: 1. Flatten every page you can to html I'm loath to do that just because I'd lose my clickstream caching... but then again it'd be better to lose some data than the site. 2. Take a look at cfaccelerate sp? Basically saves flattened html in the app. Scope. If your sneaky you can cache chunks of the page even if its dynamic much of the page is not. I do some of this as it is (navigation for example)... but I'll take a look. I'm sure I could do more. 3. turn on trusted cache (you will get a nice boost) Unfortunately not under my control (this is a shared hosting account - we're not the only app on the box). 4. pray! Well... I'm an atheist, but I get your drift. ;^) 5. cache every query you can even if for 10 seconds The application is already pretty heavily optimized. The only real queries being done is the session manager (which would definitely not benefit from caching). The main events database, for example, is loaded directly into an Application scoped CFC bundle. It makes accessing event data insanely fast compared to DB calls. The festival itself is large by any standard, but doesn't represent a whole lot of data (about 200 artists at something like 60 venues). Loading it all into memory is the biggest speed boost I can get (which I've done). This leaves the database doing only two things: saving and fetching visitors plans (saved events) which is pretty peppy and storing session data. Neither can benefit from query caching. Btw.. What does a company like crystal tech charge to host? All sorts of prices. ;^) The account we're getting (VERY feature rich) is only $26 a month (with SQL Server, tons of space, a generous bandwidth allotment). CrystalTech has upped limits and features twice and dropped prices once since I've been with them. They're a very good CF host - any problems this site has on the 31st can't truly be blamed on them.

Re: Single application - multiple users with differing specifications
Hi, I don't think this is particularly unusual... While department B wants additional features and won't use some of the existing, I am assuming that the features they share, and indeed the business rules behind them all are common. In that case, write an application that does everything for everybody, then set up a security matrix that hides/disables the functionality from those users/groups/departments that don't want it (or shouldn't be using it for security reasons). I seem to remember there was a thread on this list recently discussing various security models using groups, roles and authorities. If you're using an architechture like fusebox, you can easily restrict an action or a circuit to a particular group or user.

Re: Single application - multiple users with differing specifications
Another thought. Whatever you do, bear in mind that department C and D will be along soon with their own requirements. You need to be able to design something whereby you can accomodate this without multiplying the amount of code you produce. It's probably worth thinking How will this look if I find myself with 10 or 20 departments, each with their own requirements.

RE: Dumb Question About CFPARAM
Yeah, that ought to work. CF can't see your sql if logic, so it might as well be one giant select statement for all it cares. On the SQL Server end I would expect it to handle that just fine.

RE: Form Data Tracking
From: Joe Eugene [mailto:[EMAIL PROTECTED] We have a need to track Form Updates by users i.e. history of updates to Forms. Once the user submits a from after validation, we want to track the updates done. e.g. User A can change their Credit card info several times on a Form, we need to Track those changes and any other agreements they might have agreed to on the Form. Options. 1. Save the entire contents of the Form as *.htm/*.pdf files or populate them in the DB. 2. Implement a complex DB Relational Structure to store the content and data. Any other Ideas? Anybody else implemented something like this before? Joe, I would recommend setting up a DB structure to take care of the historical change data. I would first identify how many fields you need to track. If it is just a couple then create a couple tables and use triggers (depending upon DB platform and application load) to capture when columns are updated or inserted. For example: I want to keep track of what credit cards users use with their accounts. Assuming I did not structure the DB to accommodate multiple accounts (CC) I would implement something like this: USER --USER_ID (PK) --USERNAME --CC_NUMBER HIST_CC_NUMBER --CHANGE_ID (PK) --USER_ID (FK) --FROM_CC_NUMBER --TO_CC_NUMBER --DATE_CHANGED Add a trigger to the CC_NUMBER column in the USER table for 'insert' and 'update' and store the appropriate values. If your needs go beyond a couple columns, you might consider a complete set of historical tables that mimic your transactional tables. If you go this route, I would evaluate application load to determine whether or not triggers are you best bet or if programming the routines in code would yield better results... I have done it both ways.

Mach-II client variables
Question for the Mach-II people on this list - I have a dropdown box that appears on every page, in its own form on each page of my small application. I'd like the most recently selected item on this dropdown box to be selected whenever I move to a new page view. I can set a variable that holds the last value selected whenever the dropdown is changed, but when I move to a view that does not pass the dropdown box into the form scope, I lose the most recently selected value and it moves to the default value on the next view. I tried placing the MRU value into both session and client variables, and enabling client and session variables in the CFApplication tag, but I just got an error. Also, the most logical place for me to put an assignment for this variable is in a CFC, but I see that Mr. Corfield does not recommend doing this: It's not that CFCs cannot access scope variables, just that they should not in general (since it breaks encapsulation). The general approach is to create a CFC whose sole job is to 'wrap' the scope access so as to hide it from the rest of the app. http://lists.topica.com/lists/mach-ii-coldfusion/read/message.html?mid=81031 3532sort=dstart=2193 So where/how can I create a variable that persists this information?

RE: Mach-II client variables
I tried placing the MRU value into both session and client variables, and enabling client and session variables in the CFApplication tag, but I just got an error. As Mike Tangorre mentioned, if you want to use Client variables you will need to specify where Client variables will be stored. You can either do this using the CLIENTSTORAGE attribute of the CFAPPLICATION tag, or you can specify a default storage location within the CF Administrator. However, I would generally recommend that you not use both Client and Session variables. Usually, I think you're better off just using one or the other, depending on the needs of your application. For most relatively simple applications, Session variables are your best bet. I'm oversimplifying a bit here, of course. So, what happened when you tried to use Session variables? Remember that they also need to be enabled within the CF Administrator and within your CFAPPLICATION tag using the SESSIONMANAGEMENT attribute. Also, the most logical place for me to put an assignment for this variable is in a CFC, but I see that Mr. Corfield does not recommend doing this: It's not that CFCs cannot access scope variables, just that they should not in general (since it breaks encapsulation). The general approach is to create a CFC whose sole job is to 'wrap' the scope access so as to hide it from the rest of the app. ... So where/how can I create a variable that persists this information? If you're using the Client scope, I suspect you'll get a little less value out of the idea of encapsulating access to it within a CFC, since the Client scope itself isn't stored in memory beyond a single page request, but rather is refetched for each page request from whatever storage location you specified. If you're using the Session scope, I would wholeheartedly endorse Mr. Corfield's recommendation.

RE: Single application - multiple users with differing specificat ions
I haven't done it myself, but I *think* I have heard of inheriting forms (presentation logic) in .NET programming, and I thought that there might be a process for CF. I'm pretty sure there are forms reuse mechanisms in Windows Forms, but not so sure about within ASP.NET. There's nothing really analogous to this built into CF, since forms themselves aren't objects within CF. However, you could certainly build components to generate forms, to provide your own inheritance functionality. I don't know if it would be worth the effort. I also don't know whether there's any functionality like this within Mach-ii - I'd probably look there first. However, the serious question isn't really a purely technical one, but rather a question of process - making sure that you figure out basic requirements for all the groups that will use your application in the future, or alternatively providing so much flexibility that you will be able to meet their requirements without knowing what they will be! This isn't a trivial task.

RE: My Init() in my CFC...am I on the right track?
Well I would say you maybe working a bit too hard. If that is all you want to do you can just do this. cfcomponent cfset variables.DSN = myDataSourceName cffunction ... This sets a variable that can be used by all functions. Now the limitation of this is that you can not pass parameters to this constructor. But since you stated that you did not want to pass parameters that should not be a problem. The reason for the defacto standard of an init() method is to be able to pass parameters to some kind of constructor like mechanism. If parameters are not needed, I would feel the init() method is not needed. But I'm sure that is debatable. -- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA C code.

Re: My Init() in my CFC...am I on the right track?
A few comments here: *Typically i make my init function public so I can call it directly. This lets me do this in code: cfset mycfc = createObject(component,mycfc).init(arg1, arg2, arg3) You need to make your method do a cfreturn this for it to work right. *Your init function didn't have an argument to it. Therefore, it is kinda pointless. You can replace all of that code with just: cfset variables.dsn = However, your best bet is to make the init function take an argument so you can customize the DSN on the fly. You can still use the line above (with a real value instead of three dots of course ;) so that the CFC has a default DSN at least. *And yes, if you want a variable to availavble to all methods of a CFC, use the Variables scope.

-Original Message- From: Jeff Small [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 28, 2004 11:39 AM To: CF-Talk Subject: My Init() in my CFC...am I on the right track? cfset init() cffunction name=init access=private output=false returntype=string displayname=Initializes my object and creates the datasource variable cfset variables.DSN = myDataSourceName cfreturn variables.DSN /cffunction This should work, but I would definitely accept the name of the datasource as an argument if it might change. I don't know what the purpose of this CFC is, but I can't see any reason that you would want the CFC to be modified in that case - it should be modified at the point the CFC is instantiated (I think). The only other point is that it's common (and I think very good) practice to return this from the init() method. This returns the instance of your CFC to the caller, which is most often what you want to do in the case of initialization. Something like this: ] cfset Application.MyDSNCFC = CreateObject(ThatCFC_Up_There).init() / The CreateObject() function returns the CFC instance, so you can chain the init() call it to it. Since the init() call also returns this (the CFC instance) you can assign it directly to a variable container as is. I hope I'm making sense, I've just woken up...

Re: My Init() in my CFC...am I on the right track?
Be wary of calling functions from the pseudo-constructor - if the CFC is accessed in any way, including the doc browser, it will execute this and call the function. In general I recommend *not* calling init() automatically in the CFC but requiring users of the CFC to call init() at construction time: cfset obj = createObject(component,mycfc).init()/ Okay, this makes sense. I'm reading about 4 different sources for how to build CFCs correctly (this is the first site where we get to program from the ground floor up and not add on to an existing website, so I'm excited to try and do what I would like to see as a CFC best practice where I'm setting things up the most correct way possible. I see what you, Ian, and Raymond were saying about how I don't even really need that init function, and I was struggling with that as well, but when I consider allowing it to take an optional paramter (DSN) it starts to make much more sense. So in my code where I'm using my CFC, I'm using CFOBJECT like so: cfobject name=myObject component=mySite.myComponent So how would I use that init function using the cfobject tag? Or should I just not use that and use CreateObject() instead? cffunction name=init access=private output=false returntype=string displayname=Initializes my object and creates the datasource variable Normally, people would expect init() to be public and return an instance of the CFC itself: This part somewhat confuses me, but again, I'm using CFOBJECT and not CreateObject so I'm not really setting anything equal to anything. I'm just creating an object on the page, then manipulating it via its methods further on down the page...for example, after my CFOBJECT, the very next line is: cfset qGetNews = myObject.GetNews() cfset qGetEvents = myObject.GetEvents(5) So I'm thinking that I've instantiated an object with the CFOBJECT call, why would my init() function return the object (I mean, it makes total sense, I'm just wondering how it works, which is what I think I'm fuzzy on). Yes, that's a reasonable argument. You could even give init() an optional argument to allow users to override the DSN without code changes: cfargument name=DSN type=string default=myDataSourceName/ cfset variables.DSN = arguments.DSN/ Okay, this is definitely the first *immediate* change I'm making. ~| Special thanks to the CF Community Suite Silver Sponsor - RUWebby http://www.ruwebby.com Message: http://www.houseoffusion.com/lists.cfm/link=i:4:188874 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54

If you go to the trouble of creating an init() function like that, is it then basically the idea that it's the coder's responsibility to make sure that the init() function is chained onto the end of any object creation?

Many of the pages are quite large and complex (for example the All Events list here: http://www.firstnight.org/Content/NewYears/Artists/Explore/Events.cfm?Type=All ) but it's exactly those pages that are the most popular. As an aside, you can see the current number of active sessions and the current page's tick count at the bottom of any page. 2) My session manager is worrying me. The site doesn't use CFs built in Session management. This allows me to capture user information at the end of a session, but means that I have to manually check and destroy sessions. When a session ends it's saved in a database along with the pages viewed during the visit, information about the user agent and several other things. This process requires several database calls (perhaps a minimum of 8, but a maximum determined by the number of pages visited) and averages in the range of 40-80 ticks per session cleaned. That would be fine, except I may be cleaning several thousand sessions at a shot on the 31st. The system is SQL Server and I've optimized it about as much as I know how (there are indexes on the major columns, I've cleaned out all unneeded data, etc). Any thoughts on using multiple CFQuery statements vrs one more complex SQL call? Right now, for example, I make a call to the DB to see if the session already exists, if it does I do an update, if not I do an insert. Could it actually be faster to do an IF statement in the SQL using only one CFQUERY tag? It seems to me that with maintain connections on this wouldn't make a difference... but I'm not sure (and want to use the time I've left wisely). I am using CFQUERYPARAM and caching what queries make sense. Some other thoughts: I've actually considered placing some of the site on another CrystalTech account (on a different server of course) and using redirects to move the traffic off. Of course there's no way I could get the URLs to stay the same (outside of frames) and I wouldn't want it there all the time - just for a day or two. It would also royally screw up my log statistics. Any other ideas for kludgy, cheap load balancing? I can easily turn off the end-of-session handlers. I know that this process will take a while, but I'm not sure if it's really the performance hog that I fear. It is, after all, spending nearly all of it's time waiting for the database - sitting effectly idle. So what if the clean up process takes two minutes if the thread isn't dominating the CPU? (I will also decrease the number of clean-ups to one every 15 minutes or so in an attempt to clear out old sessions as quickly as possible.) Many (sometimes VERY many) of the sessions in memory are generated from bots. I'm considering creating a ROBOTS.TXT that would prevent bots from indexing the site for our busy time, but I fear that would inhibit them more than I want - if you tell robot's to bugger off do they come back? I'm open to any other ideas. My gut says that with the resources we have we'll just have to live with overloads unless they want to create a much simpler site (and they don't want to do that).

I don't understand even from Seans's post what purpose it serves to return this when you're using something like CFOBJECT or CreateObject() which creates an instance of an object anyway... It helps me (but isn't completely correct) to think of the createObject() call as a blank CFC. The init() call populates it to make it useful. A metaphor might be a bunch of blank paper - all different sizes and shapes. You first choose one (deciding that piece has the properties you need), then your write your note on it (deciding what, specifically that appropriate piece will do). Assume a Recipe CFC. The CFC instance begins as a blank index card. Your init() adds (via arguments, a database call or whatever) three properties: Name, Ingredients and Directions. In pseudo code it might look like: cfset MyRecipe = CreateObject(Get One Blank 4x5 Index Card).init(Write Recipe for Ice Cubes on Index Card) / cfoutput h1#MyRecipe.getName()#/h1 p#MyRecipe.getIngrediants()#/p p#MyRecipe.getDirections()#/p /cfoutput (The above brought to you by the Coalition to Prevent the Proliferation of Automobile Metaphors in Technical Discussion.)

Whatever you plan to do, I would definitely give CrystalTech a heads up about your expected traffic spike. They might be able to give you a good suggestion, and if they can't, at least they won't be caught blindsided and just unplug you or something unpleasant. Hosts tend to get cranky when the other 50 sites hosted on your server all call at once to yell at them because you didn't warn them about your expected load increase. Already done. We've been with CrystalTech for three (or maybe four...) years now, this is becoming old hat. ;^) The main problem is that I never seem to get the same folks twice - so every year it's the same explanations and assurances that the traffic won't spike for more than three hours.

-Original Message- From: Jim McAtee [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 28, 2004 4:18 AM To: CF-Talk Subject: Re: Slow (sorta) site issues - Ideas? In a shared environment you have to ask yourself to what degree optimizing the performance of your site's code is ultimately going to improve your web site's performance. Even if you were to increase performance 10-fold it's unlikely you'll see anywhere near that performance gain if there are 200 other web sites on the same server. It will of course depend on what those other sites are doing when yours is busy, but you have so little control over this that all you can do is cross your fingers. If you knew that your site was going to use a significant percentage of the server's resources then it may be worth the effort. If you don't know this then it's just a crap-shoot. Too true - believe me, I understand this (this is the ninth year I've done this site and we've had similar problems every year). In this case our application, just on that one day, uses up to and over 95% of the available resources. Our host annually threatens to shut us down to protect the integrity of the other applications on the box and we annually start slowly down just in the nick of time. For example, last year we did just under 775,000 page views (not hits) for the month of December. But a third of those views were on the 31st (and 20% of them were on the 30th and 11% on the 29th - it's quite a steep, but regular, curve). A full quarter of the traffic for the 31st came in between 10am and noon. It's around 11:15 every year that we get a call from the host. ;^) Of course these aren't insanely large numbers but in general they're pretty high. But for a shared hosting account they're quite high. My worry this year is that 1) New Year's Eve is on a Friday, 2) It's now a holiday for nearly everybody and 3) it's predicted to be the warmest New Year's Eve in many years. I worry that we're going to do significantly more traffic this year.

Re: Form Data Tracking
If you just want to *see* the data and don't want to be able to extract it back out again you can use a more obtuse approach and store the submitted form data in a long text field, via cfdump if your needs (and data qty)(are very simple and via a loop and table row construct if more complex. You'll need a table that tracks the User's ID number as a separate field, as well as a date and time of mod. I usually log the entire submitted form scope minus a few key things like submitted passwords, the fieldnames field, the submit button name or anything else I don't want stored in the clear in a db (uh... like a cc number). You can fancy this up by encrypting data as well.

Re: Slow (sorta) site issues - Ideas?
Have you thought about using a web cache system like Coral? http://www.scs.cs.nyu.edu/coral/ If you set the no-cache http header to true it caches pages for 5 minutes before requesting a new copy. With a bit of experimentation it should be possible to track the user agent their bot uses and set the no-cache header only for that. You'd probably have to do a bit of testing to make sure searches hit your site directly rather than the coral cache, but it might be worth a try.

cfset variables.DSN = myDataSourceName This might be a little off the best CFC practice topic, but why not create a second CFC to govern all contact with your database(s)? This way you don't have to worry about each CFC that lives in your world understanding database lingo and knowing what the datasource names are -- there's only one spot where it needs to happen. We've done this (the component is called database.cfc), and it's really helped to streamline our code. All queries and other DB-specific interactions are done through this component. Other CFCs don't need to know anything about it other than invoking the proper method and passing the right arguments.

Re: My Init() in my CFC...am I on the right track?
On Tue, 28 Dec 2004 14:18:14 -0400, Matthew Drayer [EMAIL PROTECTED] wrote: cfset variables.DSN = myDataSourceName This might be a little off the best CFC practice topic, but why not create a second CFC to govern all contact with your database(s)? This way you don't have to worry about each CFC that lives in your world understanding database lingo and knowing what the datasource names are -- there's only one spot where it needs to happen. We've done this (the component is called database.cfc), and it's really helped to streamline our code. All queries and other DB-specific interactions are done through this component. Other CFCs don't need to know anything about it other than invoking the proper method and passing the right arguments. You absolutely could (and some might say should for maintenance reasons) do that. I just didn't want to muddy the waters with OO concepts when all he was looking for was feedback on his syntax and basic usage. While it's good to be cognizant of OO patterns, that's probably a bit beyond the scope of any beginner's use of CFCs. I'd suggest getting the syntax and basic usage down, and then refactor using OO-patterns (via DAOs) later.

If one of the things you're looking forward to doing is using some methods with Flash Remoting down the line, and you made an insert() method say, that was looking for a struct (insert(myStruct) for instance) can Flash provide the method with the appropriate structure that ColdFusion (the CFC) is expecting?

When I originally read your e-mail, I thought that you wanted to eventually be able to pass back the name of the datasource to your calling code (i.e., my_template.cfm needs the name of the datasource). From your follow-up posts, it looks like all you really want to do is use the datasource name in that CFC, in which case the getDSN/setDSN method really aren't necessary. Apologies for any confusion there. cffunction name=getDSN access=public output=false returntype=string hint=Returns the name of the datasource cfset variables.DSN = myDataSourceName cfreturn this /cffunction cffunction name=setDSN access=private output=false returntype=void hint=Sets the name of the datasource cfargument name=dsName type=string required=true hint=The datasource name to set cfset variables.DSN = arguments.dsName /cffunction /cfcomponent Again, if you don't want your calling code (the CFM template that invokes the CFC) to access the datasource name, then you really don't need these two methods -- you can use your initial approach of directly setting the variables.DSN value in your init() method and chop the methods out. Any other method within your CFC that needs to use variables.DSN can then directly refer to it rather than having to call getDSN() to get its value. Calling code: cfset variables.objMyCFC = createObject(component, path.to.my.CFC).init() cfset variables.myDSN = variables.objMyCFC.getDSN() Your calling code (again, the CFM template that invokes the CFC) now only needs the first line to actually create an instance of your CFC: cfset variables.objMyCFC = createObject(component, path.to.my.CFC).init() At this point, you have both created a new instance of the CFC and called its init() method at the same time. You now have a full-fledged CFC object and you can simply call other methods in that CFC using this syntax: cfset variables.myQueryResult = variables.objMyCFC.getMyData() Keanuwhoa/Keanu I think I need to print that out and go thru it slowly. Is your calling code in your page? Why do you use your getDSN function after you've already created an object and initialized it? If possible...could you please just sort of briefly explain the three functions? You're using some weird syntax in your init (dsName:myDataSourceName) that I don't kinda...well...get... I understand there's a lot to take in at the beginning!! As to the first question, the calling code is the CFM template that actually creates the CFC instance, and is where the variables.objMyCFC line of code would go -- *not* in the CFC itself. As I said before, I put in the getDSN line because I thought your *calling code* needed that value for some reason. Since it turns out it doesn't, then you can eliminate that line altogether. Lastly, the init syntax I used for setDSN() is an alternative way of calling CFC methods that some people don't use and some do -- I do. When invoking CFC methods, you have the ability to use named arguments or use positional arguments. Named arguments, as you might guess, is when you explicitly note the argument name that the value applies to. So, taking the setDSN() method from earlier, you'll see the I've created a cfargument called dsName in the setDSN() method itself that is expecting a string value. In the init() method, where I called the setDSN() method, I simply put the name of the argument in front of the value for clarity. Positional notation, like most other programming languages, is simply putting the values in the correct order without specifying the argument name that it goes with. ColdFusion then implicitly takes the first value and associates it with the first cfargument in the method being called, the second value with the second cfargument, and so on. So you can write the setDSN() method call in three ways (two using named arguments and one using positional arguments: Named: cfset setDSN(dsName:myDatasourceName) or cfset setDSN(dsName=myDatasourceName) Positional: cfset setDSN(myDatasourceName) Any of the above is perfectly valid. I personally prefer named arguments because it makes my calling code more explicit in that I don't have to go open the CFC to see what the argument name is that I'm passing in. Further, if you use positional argument notation and the order of your
Re: My Init() in my CFC...am I on the right track?
Named: cfset setDSN(dsName:myDatasourceName) or cfset setDSN(dsName=myDatasourceName) Aha! This I got immediately. I understand it all now and once we were both clear on what I was doing, it makes perfect sense both in what you were doing, and syntactically what you were writing. I've seen the lower named method in 99.99% of the examples that use that method, I don't honestly recall ever seeing the upper method used. But once I see what it is, it makes perfect sense. Positional: cfset setDSN(myDatasourceName) Any of the above is perfectly valid.

It's something I'm going to start trying to look at closer. Further, if you use positional argument notation and the order of your arguments gets messed up, then you will be setting the wrong values for each argument! ...again, another terrific reason... I should note that many prefer positional notation because it's just like Java, JavaScript, etc., where you just pass in the value, and it keeps your coding guidelines more consistent. Exactly! For me it was simply force of habit... Hopefully this helps a bit more?

shopping cart, session variables - best practices
I'm setting up a shopping cart for a jewelry store. I'm curious, what is performance limit for storing data in session variables? The following are lists: Item No (itemID used in check out) Item Qty (in case someone wants more than one) Item Price Item Description (most descriptions about 50 characters. ex: Ruby and gold drop-earrings) Most customers will not go above 3 or 4 items so I'm not concerned for this project. Just curious in general. At what point would storing data impact performance? Also, is updating session variables all that much quicker than updating a database. For example a customer wants two pairs of a particular earring instead of one. -- gil ~| Special thanks to the CF Community Suite Gold Sponsor - CFHosting.net http://www.cfhosting.net Message: http://www.houseoffusion.com/lists.cfm/link=i:4:188911 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
Re: shopping cart, session variables - best practices
I'm curious, what is performance limit for storing data in session variables? Memory (RAM) is really your only practical limit when using session variables. Just make sure you make your session timeout a practical interval. and (assuming you are on CFMX) make sure you set both your max and default memory sizes to the same value in the CFADMIN. It's conceivable that if you have too many sessions going at once, you could use up all the available RAM and run into out of memory errors, but based on the limmited data you are storing in session, you will likely hit another bottleneck point (ie: CPU or DB connections) before your sessions exceed available RAM. Also, is updating session variables all that much quicker than updating a database. For example a customer wants two pairs of a particular earring instead of one. Session variables are always going to be faster than making trips to the DB. -Cameron ~| Special thanks to the CF Community Suite Silver Sponsor - CFDynamics http://www.cfdynamics.com Message: http://www.houseoffusion.com/lists.cfm/link=i:4:188912 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54

I'll bet you've got isDefined(someUnqualifiedVariable) in your code - if the variable isn't defined, CF looks up the list of scopes (per the docs) and will eventually attempt to look in CGI scope if it hasn't found the variable elsewhere. If the connection between the browser and the web server has closed (for a variety of reasons) then the JRun connector will fail to read the variable from the header. You're much safer using structKeyExists(someScope,someUnqualifiedVariable) which is not only much faster but will avoid the (harmless) errors you are seeing, e.g., cfif structKeyExists(variables,codesnippet) ... /cfif -- Sean A Corfield -- http://www.corfield.org/ Team Fusebox -- http://www.fusebox.org/ Breeze Me! -- http://www.corfield.org/breezeme Got Gmail? -- I have 6 invites to give away!

There's no particular reason to use list. I was wondering about using arrays instead, and then got pulled elsewhere.

RE: FB4 on CFMX problem with set
From: Duncan I Loxton [mailto:[EMAIL PROTECTED] fuseaction name=checkUser include template=qry_checkUser.cfm/ if condition=validateUser.recordcount is 1 true set name=request.usr_id value=#validateUser.usr_id# / /true /if /fuseaction When I get thru the login process the request.usr_id isnt set - why?? I would first verify that the query returns a record. Can you verify that the query returns what you are expecting? Also, I would change your conditional statement to take into account multiple records or 0 records: if condition=validateUser.RecordCount EQ 1 true set name=request.usr_id value=#validateUser.usr_id# / /true false false /if Just cfdump the query first to make sure the values you expect are there... Then go from there.

Re: STICKY Application.datasource
Unless it's really necessary I would try not to set datasource as an application variable, either: cfset datasource=CODAGenomics or cfset request.datasource=CODAGenomics Andrew. I seem to have a sticky application variable. How do I get it to change? The application.cfm file is: cfapplication name=CBRLVer11 sessionmanagement=Yes clientmanagement=Yes SESSIONTIMEOUT=#CREATETIMESPAN(0,8,0,0)# cfparam name=Application.datasource default=CODAGenomics cfparam name=Application.name default=CODA All the queries use: cfquery datasource=#application.datasource# name=xxx So, when I changed the application.datasource default value, the related scripts Still bring up the old value. Have tried clearing the browser cache, etc. etc. Any idea why and how to fix? TNX if you can shed some light on this problem.
