Re: CF clustering with Standard version vs Enterprise version

2009-12-01T15:13:53Z

We always had good luck with hardware load balancers from Coyote Point, managing connections to 4 or 5 clustered web servers. For apps that needed to maintain seamless persistence, we used client vars (stored in the central DB), which allows the application to keep a running connection to a user even when the server they were on gets dropped from the cluster. There is some overhead with client vars, like having to WDDX non-simple variables, but it really worked very very well.

RE: CF clustering with Standard version vs Enterprise version

You can use client variable stored in a database to provide 'session'
failover when load balancing without Enterprise. We use two load balancers
(for redundancy) from http://loadbalancer.org/. They are very reasonably
priced, provide good throughput and have great support. I've been using them
for about 5 years and never had a problem. And I've always gotten great
support when I needed it...

Apologies for this vague question.

No need to apologize, but vague questions tend to get vague answers.
There are plenty of mechanisms for load balancing, using either
hardware or software solutions. You're looking for something that lets
you balance web servers, not application servers. If you're using
Windows and IIS, some versions of Windows Server include
software-based load balancing. If you're using some other environment,
it may or may not include software-based load balancing.

In any case, without CF Enterprise, you won't be able to provide
session failover. But you can use any standard load balancing stuff to
provide simple load balancing no matter what application server you're
using.

cf6 & above defaults to utf-8 (unless somebody changed it) but just FYI that

>>I'm processing DB columns with text containing – and —.

This means you are storing HTML code in your db text fileds.
By doing so, you are not supposed to use these data for other purpose
than HTML rendering.
If you need to use them for other purpose like generating text under
some non HTML environment,
you must get rid of these HTML codes or convert them.

For instance, I have an application which generates passports for
participant in conferences
in some RTF document to be printed.
Of course, HTML code inside an RTF document wont be rendered properly by
MsWord.

I'm grabbing data from an RSS feed and loading it in a DB. The description field contains the – and —. I want to display (print) the description on subsequent CFM pages. I believe the current encoding is utf-8 as <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> is in the header. I've tried to replace – and — with – and —.

CF clustering with Standard version vs Enterprise version

2009-12-01T07:43:44Z

Can someone enlighten me on the best direction to go for setting up clustering with CF Standard versions. I realize you can do this with the Enterprise version but is there an operating system/web server or software based method to manage load balancing, then point to my different CF instances? I'll be using CF 9 Standard. Apologies for this vague question.

Re: cfsqltype error

2009-11-30T16:41:25Z

Mathew is correct of course. Also, the CF error rarely ever points to
the correct line when the issue is with a SQL statement.

you could wrap your value in val() or try an iif() within the NULL
attribute of cfqueryparam if your column allows null values.

Re: Best Way to Handle Multiple Related Selects?

2009-11-30T13:10:31Z

Thanks for the suggestions, all. I ended up simply handling it with WDDX and old-fashioned Javascript. I was pretty disappointed that CF's new bind options proved to be a poor solution for more advanced needs, but in this case my lists are of reasonable length so AJAX is probably overkill anyway.

RE: cfsqltype error

2009-11-30T12:48:10Z

If you change something on the server (add a column to a table for example)
ColdFusion still holds onto the "old" schema. Consequently it tries to
insert into a column that is incorrectly mapped (via the tableid or whatever
in the system tables of the db in question).

Here's a post with the scoop.

http://www.coldfusionmuse.com/index.cfm/2005/4/29/dbschemaChange

To mitigate it you need to force the schema to be recached. Restarting CF
does it of course, but so does changing some of your queries - adding a
space works well on selects for example.

Hello folks,

This has to be something simple as I've seen example of ppl getting it to
work but I'm having problems running some JS on a cfinput type datefield.

Part of the code
----

<script type="text/javascript">

function calcAge(){
alert('calc age');
return true;
}

</script>

<cfform name="patient_form" action="patient_action.cfm" method="post">

<tr>
<td><b>Birthdate:</b></td>
<td><cfinput mask="DDMMMYYYY" name="patient_bdate" type="datefield"
value="" onChange="calcAge()"></td>
<td><b>Age:</b></td>
<td><cfinput type="text" name="patient_age" value=""></td>
</tr>

----

I've also tried onClick (Works if I click on the input box but not the
calendar icon), OnError, onValidate, onKeyDown, onKeyUp.

Just change that "EQ" to "LT" and you'll be set.

Date Compare Help

2009-11-29T09:25:37Z

Hi all,
Trying to do a date compare on a file datelastmodified (retrieved through CFDirectory).
If the file datelastmodified is older than 1 hour previous to Now, I want to refetch the file.

In other words, if the file is posted at 9:00 AM, if it's presently 10:05 AM, I want to get a new file.

Here's my attempt, but I can't get it to work right:

DateCompare(dirname.DateLastModified, DateAdd("h", -1, Now())) EQ 0

Thanks!

Mark

Look for the error message in cfusion-out.log and cfusion-err.log.

Thanks to everybody that chimed in.

The extensions are, as you've discovered, a bit shaky in the beta. The
only way I know to get them to work in Beta 2 is to install CF Builder
"standalone", rather than as an Eclipse plugin. I expect that'll be
ironed out before release.

CFBuilder extensions not working

2009-11-27T07:26:40Z

I am having the damndest time getting any of the CF Builder extensions to work. I have a CF multiserver setup with CF7, CF8, and CF9 all running on JRun. I have CFBuilder installed as plugins to a clean version of Eclipse 3.5 64-bit for OS X. I installed the basic extensions to map to the CF9 server. I also installed a couple from RIAforge, including the CFProperty Inspector.

However, none of these extensions are creating the files they are supposed to. An example is the CFC Generator. I open an RDS (any of the three) and select a database table. I click to generate the CFC (or the ORM CFC just for kicks), select a directory in any of my projects, and the files are never written out.

This is driving me crazy, especially since when I used this at the Chicago Flex training last week, it worked fine.

Anybody have a clue why this is happening?

The latest attempt at least shone some light on it, I am getting this error sometimes, but not all the time, in teh Console when trying the Adobe CFC Generator. But I am even more confused now because I have the server set up properly, I can go to this URL in my browser without a problem.

11/27 10:28:41 error Requested resource 'File not found: /Adobe CFC Generator/handlers/index.cfm' (File%20not%20found%3a%20%2fAdobe%20CFC%20Generator%2fhandlers%2findex.cfm) not found

Re: ORMExecuteQuery problem

2009-11-26T21:21:26Z

There seems to be some problem with the type conversion. So out of curiosity, can you check what happens when you replace the query with ormExecuteQuery("from User where region_id =? and usergroup_id=?", [1, 1]);

If that works fine, would you mind sending a test case to me (rukumar at adobe )? It would be great if you can also add the stacktrace for the null pointer?
