Re: cfthread running condition?

Yeah, I've been wondering why this would use multiple threads when the
aim is to deliberately single thread the execution.

RE: cfthread running condition?

2008-08-30 Thread Rick Faircloth
What!  Are you saying the Emperor has no clothes!  :o)
Why point out the obvious and ruin a perfectly good, pointless discussion!

It very well may be time to go back to just consolidate more and more
code into one or at least few threads.

I think I got started on the separate threads way back when I was first
testing parts of the functionality in a browser and wanted feedback
through the browser output about how the processing was working.

Then I moved that code into separate templates that had to run in a
specific order to process all the data. (54 templates at this point)

I think I've just become obsessed with making threads bend to my will.
It's definitely been a good learning experience about cfthread.

I'll have to sit back and reconsider how best to use cfthread now
that I'm consolidating many similar functions into single templates
and running them as scheduled tasks still.

I wish there was a way to watch scheduled tasks at work...showing data
processing, outputting results, starting and finishing of tasks, etc.
I generally just run the tasks in a browser when I need to see feedback.
Or I send myself an email with results I need to see.

Am I missing some sort of obvious feedback method when scheduled tasks
(and cfthread's, for that matter) are run?

Re: cf8 enterprise failover

2008-08-30 Thread Richard Steele
Great, thanks. How much memory is required or recommended for each instance? 
I'm on a Windows Server 2003 Standard Edition with 4 GB of memory (its max). 
How many instances would be recommended for that amount of memory?

Yes.  You add one or more instances to one or more servers.  Then you define 
a cluster, add the instances to it, and choose a load balancing algorithm. 
You then associate that cluster with your IIS site (or apache virtual server 
etc)

In my experience, clusters can be a little cranky if you are making changes 
to them, but once they are up they work pretty well.

The main gotcha's for clustering IMO are:
* Features that require subsequent HTTP requests to target the same initial 
server (cfchart, cfimage)
* Data that is specific to a users and stored in a persistent scope like 
session or Application does not automatically follow users from once 
instance to another.

Session replication can solve the latter, but still has some problems I 
think, and not many people seem to use it.
Sticky sessions eliminates both problems for the most part, and seems to be 
the most common way to handle clusters.  Of course, the failure of an 
instance won't be helped by sticky sessions since that only sticks a users 
to an instance as long as it is still up.

Re: cf8 enterprise failover

2008-08-30 Thread Matthew Williams
By default CF uses 512 Megs + up to 128 Megs of memory per instance.  
You can configure that to be higher, though I wouldn't go any lower.  
I'd go with a maximum of two instances with that type of system in a 
production environment.  This way, you could allocate about 1.2 gigs per 
instance and be relatively safe.  At least, that's what I've found to be 
the most optimum on my end.

Brad Wood wrote:
 How do you define working?  When you can't place CFCs or XML objects in 
 your session scope without ugly erros, I don't call that working. 
 Serialization of complex objects has plauged session replication for a 
 while.  CF8 made CFCs serializable and that was very good, but to this day 
 (and to my knowledge), ColdFusion is still incapable of serializing complex 
 variables (Arrays, Dates, Query objects) within a CFC. (Adobe Bug #70580)
 I know there are people who use session replciation, but in general, my 
 perception (from this list anyway) is that a lot of people have simply 
 enabled sticky sessions and then clocked out.
   
I define working in that we host about 130 applications, and none have 
had issues (beyond that MachII app) in 2 years with our setup.  At 
least, I've not had any complaints.  Now, we do use session stickiness 
in addition to the replication, so in theory we wouldn't have any issues 
unless the server goes down.  We've actually had 98+% uptime on the 
servers, so maybe we just don't come across it?  Mayhap we just have 
really boring devs that don't serialize objects.  I don't know.
 I'm not sure what you speak of, but to my knowledge this is not operation 
 out of the box since cfchart's cache location defaults to a local directory. 
 (Which is why it qualifies in my gotcha catagory) Your options are to cache 
 to a shared network location, or enable some sort of file replication beween 
 your chart caching folders.  Keep in mind, I didn't say it was impossible. 
 I simply said it was a gotcha.
 To my knowledge, cfimage does not allow customization of the caching folder.

   
Yes, sleep addled brain at work here.  I should say that since all of 
the sessions should stick, we don't typically have an issue with 
CFCHART.  Although, I should look at setting those folders as targets 
for our DFS shares.

I guess the only real thing I have going here is that, in my experience, 
life has been 1000x better since we've moved to multi-server with 
session replication and stickiness.  Customers and the public no longer 
catch a 500 server error (which happened frequently before I came on 
board).  The only complaint I've had for our public facing servers in 
the last few months is an issue with our front end balancer.  If a 
CFHTTP request gets routed back to the same server making the request, 
the load balancer fails the request.  This only applies to non-CFM 
related requests, so calls to XML files and images would fail 
intermittently.  The workaround for that is to use things like CFFILE 
instead, but I have no control over the front end load balancer.

Re: cf8 enterprise failover

2008-08-30 Thread Brad Wood
This is one of those things no one can really answer but you.  I can make 
suggestions, but other people on this list can probably make better ones.

Assuming you are 32 bit, your maximum heap size you can allocate to each JVM 
is 1.8 Gigs.

Factors you need to take into consideration are:  What else is running that 
server?  The operating system will need some memory.  Is that server 
dedicated to CF or are there a mail server, and a SQL server on it as well? 
How much memory does your CF application use at peak load times?



Also, you need to decide what you want to get out of clustering.  The topic 
of this thread says failover, so I'll assume redundancy in on your docket. 
For the record, keep in mind that multiple instances on the same physical 
server will not help in the event of hardware failure, network failure, 
power failure, OS failure, Web server crashes (IIS, Apache), or Database 
Failure.



This is totally my opinion based on some assumptions, and anyone else is 
very welcome to dissent, but if you have an average CF app on a dedicated CF 
box, I would probably start out with a simple cluster of two instances. 
Give them both 1 Gig min and max heap size and see how that treats you.  Set 
it up as regular (non-weighted) round robin, and enable sticky sessions.

Then run some tests.  Start putting some load on your app and watch your 
memory usage to see what it is doing.  Then shut down an instance and see 
how well it is handled.



There is an ideal set up for you, but I don't know of any magic formula to 
find it without testing and experimentation.



Here's a recent article by Mike Brunt on the topic.

Wildcard characters in filepath?

2008-08-30 Thread Rick Faircloth
How can I use wildcard characters in a file path?

Is it possible?

I have a data vendor that makes data available for download
using file paths that use as part of the path, .../2008_0830_103028/

In other words the paths are auto-generated and include the
year, date, hour/minute/second, in the file path.

I want to just specify the year and date in the path
and use .../2008_0830_xx/... so I can automate the
data processing.

I could use contains, I guess, but I'd rather specify
the path using variable characters.

How can I do this?

I bet it has.  In spite of the few gotcha's I believe it is a better world.

 CFHTTP request gets routed back to the same server making the request,
 the load balancer fails the request.

This _MAY_ be a routing issue if your web server has a WAN IP as well as an 
internal one.  I have see similar problems where requests going from one 
load-balanced server come back through the load balancer to the same server 
get stopped.  The fix I have found to be most useful is to put each server 
in its own host file.
Normally, when you ping your domain, it resolves to your load balancer IP. 
Set up your server's host files so when you ping it from that server, it 
resolves to the local IP address of that server.  In that way if will bypass 
the load balancer.

I wish I knew more about the networking aspect of the whole thing but I 
don't.  All I can offer is a post Ben Nadel has that I think is caused by 
the same issue:

If it is for an HTTP request, the answer is no.
If it is for CFFILE, it is still no.
Using wild cards could mean that several files could be returned, and
both HTTP and CFFILE can deal with only one file at a time.

However, you could use CFDIRECTORY action=list with a filter to get

I think, at least as far as remote access to ftp sites are concerned
(which is part of my issue), I see in the docs that I can use
listdir in cfftp to get the files in a directory, so that solves
the download side.

And I read in this blog:

http://www.bennadel.com/index.cfm?dax=blog:1221.view

can a pipe can be used to provide multiple filters to do this:

cfdirectory
action=list
directory=#ExpandPath( './' )#
listinfo=name
filter=anna.*|ben.*
name=qFile
/

And a ? can be used to designate single-characters wild cards.

Thoughts on this?

That's exactly what I'm doing, Justin.  And I'm trying to integrate data
from two different data providers with very different db schemas and will
probably have to add a third provider who yet another different db schema
to the mix.

Trying to get all this data in every day, parse it, then get it into
my local database, then uploaded to my production server is a big pain.

I'm able to almost completely automate the process with one vendor, but the
other one is the one that's causing all the problems and has me searching
for wildcard methods, etc.

You're right about the cfftp function.  I do use that with one and I'm trying
to get the other one to give me direct access via ftp instead of having to
click links on their site to get to the data folders.  If I can get direct
access via ftp I can use the listdir feature of cfftp to create that list
of filenames and bypass having to use wildcards at all.

Thanks for the tip!

 The question would really just apply to files.

Well, it DOES depend on how you want and can finally get the file.
Is the file on YOUR server, or somewhere else.
Is the file accessible through HTTP, FTP ?

If the file is not on your server, surely you cannot use CFdirectory.
If you only have HTTP access, you can only get all files names, no filter,
provided the server allows directory browsing.

If you have an FTP access, then you can get the list of all files, no 
filter either.

When you have all files names, you can loop on them and find the one 
that meets your criterion using
so regExp.

RE: Wildcard characters in filepath?

2008-08-30 Thread Rick Faircloth
Gotcha...

I wonder if cfhttp can help with this situation.
I've never used cfhttp for anything and only know what I just
read in the docs, but I'm still not clear on what I can do with it.

The way one of my data vendors works is like this:

They send me an email every morning with a link to my directory
of files for the day.

I click on the link and it takes me to a page in the browser that
lists the files I need.  I've started using FF 3 to download the
files because Windows Explorer's ftp capability just wasn't able
to get the job done.

I've tried getting into the site via ftp, but can't.

Is there some way I can use cfhttp to access the files listed
on the web page and download them?

Re: CF8 Dedicated server recommendations

2008-08-30 Thread Dan Crouch
I have a dedicated server at CFDynamics. It is pretty cheap for a dedicated 
server setup and in the year and a half I have had it up and running, I haven't 
had downtime at all. So their infrastructure has been more stable than anything 
else I have used to date. We have also been researching some SAS 70 compliant 
hosts and may be using hostmysite in the near future as well.

Verity Collection Unable to create temporary file

2008-08-30 Thread Mike Kear
I have a verity search faciaility on one of my sites, and we recently
moved the site to a new server box.Now, when i go to refresh the
indexes I get the following error:

Unable to create temporary file

And the error is pointing to the line containint the CFINDEX tag .

I guess this is something to do with the permissions, but i'm not sure
what is needed - I had no such problem setting the search up on my dev
machine, nor on the previous box.   I managed to use CFINDEX to delete
the collections, and to create them again programmatically, but this
error occurs when i go to populate the collections with data.

What do i need to do ?(or perhaps i should ask, what do i need to
ask my Sysadmin to do?)

Re: Verity Collection Unable to create temporary file

2008-08-30 Thread Barney Boisvert
sounds like the user the CF server runs as needs write access to the
Verity temp directory.  I don't know what that directory is, but you
should be able to find our from the dogs for you platform.
