RE: [flexcoders] LiveCycle Data Services 2.5 - Using dynamically referenced queue destinations

[Eric D Anderson]

Hi Brian,

 

We have some code that will make what you are trying to do easier, but
it is currently available in our private beta program.  Can you email me
off-list ([EMAIL PROTECTED]) and I'll get you set up in the beta where
you can get access to this?


Thanks

Subject: [flexcoders] LiveCycle Data Services 2.5 - Using dynamically
referenced queue destinations

 

Our application currently uses a large number of queue destinations. We
create the 
destinations in the messaging-config.xml file and compile our app
against the FDS 
configuration files (and then upload to the J2EE container). There are
100+ queue 
destinations defined in messaging-config.xml currently.

Our Java backend creates these queues in ActiveMQ or JBoss (using the
same queue 
destinations as configured in messaging-config.xml) and pumps data in to
them. 

I've read through the beta documentation and there is a section on
"Configuring components 
with a bootstrap service". Do we need to create a class that
creates/exposes these queue 
destinations to the Flex app, or can we just attach Flex consumers to
queue destinations and 
the new LCDS libraries will do the work for us?

Any input you might have would be appreciated.

Thanks,

Brian

 

RE: [flexcoders] Re: FDS/Hibernate - LazyInitializationException when writing AMF output

Hi PW,

 

I'd suggest that we add you to the latest Data Services beta because
either we have fixed this issue, or we will fix this issue in the next
release.  Can you contact me off-list and I'll add you to the beat so
you can test DS with the latest DS and hibernate assembler.

 

Thanks

This is happening from FDS... flex.data.assemblers.HibernateAssembler
uses a function called fetchObjectProperties() that's supposed to load
them all while the session is open right?

I've seen in other posts that FDS eager fetches the properties in the
Assembler, so that they are available during serialization... 

am I missing something here?

Hi,

 

The info that Matt provides below is
totally accurate.  I would only add; please reach out to us if you have a
compelling reason to use our technology and would like to explore custom
pricing options.  

 

Feel free to reach out to me directly ([EMAIL PROTECTED]) as I don’t frequent

Per application means a conceptual application.  Each one of
our samples is an application.  While the component explorer is made up of
over 100 small application.mxml files it is still conceptually 1
application because it’s delivered through that one URL. 

 

So for departmental it doesn’t matter how many CPUs you
actually have, you are limited to 100 concurrent users across the whole cluster
for a given application 
(section 3.1.2 in the EULA doesn’t say per CPU it says per CPU
group/cluster).  If you want to support more than 100 concurrent
users you will need to use the enterprise license.

 

HTH,

Matt

Flex Data
Services (Departmental license) : $6,000 per CPU, with a
limit of 100 concurrent users per cluster

Q3: How do you measure concurrent users in the Flex Data Services
departmental license?

A: Concurrent users will be counted by the number of unique IP
connections to the CPU and/or CPU cluster

We have two hardware load balanced servers both with two cpu's in
them. They are not clustered in anyway.

Does this mean I can have 200 concurrent users (100 for one server and
100 for the other server) because each server has 2 cpu's and is 12k each.

Or does this mean that I can have 400 concurrent users (100 per cpu
per box) so 2 cpus one server and 2 cpu's the other gives me 400?

The EULA also reads:
http://www.adobe.com/products/eulas/pdfs/AdobeFlexSDK-DataServices2_0.pdf#search=%22flex%20data%20services%20departmental%22
About 100 per application per cpu.. But this is beyond me.

Any help. Thanks

David

RE: [flexcoders] flex 1.5 : AMF and ports and Max users

[Eric D Anderson]

You can configure your data transport
channel in the data-management-config.xml file in your FDS application.

 

FDS can support more than 100 users per
CPU.  Scalability is very application dependent, but our tests have shown that
you can support 1000’s of concurrent users per CPU.

Well
thanks Eric but my question is :

- How do I use Rtmp, where do you declare this ? and If I use rtmp for my remoteObject
will it be "faster" ?
- Still don't understand if ONE CPU could support more than 100-200-300-400
users ...

Eric D Anderson a écrit : 







FDS can use HTTP(S), AMF/HTTP(S) or RTMP(S) for data
transport.  You need to define each destination to use one (or more) of
those data transports.

 

In terms of scale, FDS Dept edition is targeted at applications for
work groups or departments (you deploy an application for a 50 person call
center). FDS Enterprise is targeted at larger applications with hundreds, thousands
or tens of thousands of users.  Our internal load testing (which will be
available in a public document on the adobe.com website shortly) shows that FDS
scales linearly with a web server and is typically limited by the performance
of the systems it connects to – our messaging performance is typically
limited by the JMS server we’re talking with.

pricing for clustered solution



 







Hello
flexcoders
I found no info on the Adobe site about pricing, 
from the threads I understood that FDS is priced 20K$ per CPU for unlimited
concurrent amount of users. We are building the solution that will require
support thousands of simultaneous users on the site and will require up to 100
application servers as we grow. 
I know that Adove guys are reading this list so I have a questions first of all
to them and to those who have some relevant info about this

- Is it true about pricing 20K$/per CPU for unlimited users?
- Do you have some discounts policy for such cases as described above? 
- How much will it cost us to license FDS for 100 dual CPU servers?
- Can we license only AMF gateway without any client pushes etc with discount?

The problem is that we simply need amf gateway on that 100 servers and paying
4M$ just for gateway is too kewl as for me. I'd better develop one on my own :)


We are investigating alternatives such as OpenAMF but we want to know the
amount of money we need to spent on original Adobe solution.

Thanks in advance for any comments.

RE: [flexcoders] What is the difference between versions of Flex Data Services

[Eric D Anderson]

Hi,

 

To clarify:

 

FDS Express

COST: Free

LIMITATIONS: no more than one application
per CPU.  No clustering (through J2EE) or load balancing (through hardware
or software load balancing) allowed.  No multi-CPU deployments of FDS
allowed.

NOTES: Multiple applications per 1 CPU ok,
1 dual-core CPU ok.

 

FDS Dept

COST: 6K per CPU

LIMITATIONS: No more than 100 concurrent
users per application.  

NOTES: Can deploy on multiple CPUs,
clusters, with load balancing.

 

FDS Enterprise

COST: MSRP 20K per CPU (work with Adobe sales
for the price that is appropriate for your project)

LIMITATIONS: none

NOTES:

 

Hope this helps.

I would love to
hear if there is any other similarly priced server software technology (and I'm
not talking ERP or something) on the market.

I am in awe.

Hank

 

But has anybody
bothered to call and ask Adobe what this all means or are we all relying on
speculation and gossip of a news list and based on that information, judging
Adobe to have priced themselves out of the market. I suspect a company as
experienced as Adobe is very much aware of the market and what other similar
technologies go for.

 

I would suspect
the way it might work is that a large organization would have a FDS server that
many other servers talk to for the FDS tasks. This is supposed to be a
multi-tier concept is it not? Do you guys running large enterprise systems put
an Oracle database server on all your web servers? We do not. 

 

That is my
uniformed 2cents. And since I know our organization can get by for a long time
on the free version and maybe, eventually, someday the 6k version; when and if
we get around to using FDS in the first place. So far what I have played with
works very well with the ColdFusion flash remoting connection, which is a free
upgrade to our ColdFusion license. I am not too concerned about the large
version for the foreseeable future.

RE: [flexcoders] Problem with listItemRenderer and AddChild

[Eric D Anderson]

Hi,

I tried this with the Flex 2 beta and I don't see any problem.  Can you confirm 
you're using Flex 2 beta?

Thanks

Eric

Subject: [flexcoders] Problem with listItemRenderer and AddChild

Hi again;

This might be a bug. The code at the end of this message creates a 
list with a custom item renderer. The renderer handles clicks by 
changing the component's state, effectively adding a button.

This works fine as long as the list property `variableRowHeight' is 
set to `false'. If it it set to true, very strange things happen. 
Clicking on the first row adds a button to the second row. 
Repeatedly clicking on the first row will add a button to the second 
row, remove it, add it to the first row and then remove it.

Does anyone know a way to dynamically add and remove children from a 
custom list item renderer that allows variable height rows?

Thanks.
Tobias.

Here's the code:

- TestAddChild.mxml -

xmlns="*" layout="absolute">


Alpha
Beta



   




- ItemRenderer.mxml -


http://www.macromedia.com/2005/mxml"; xmlns="*" 
click="DoItemClick(event)"
height="60">

RE: [flexcoders] converting to RTF in flex

[Eric D Anderson]

One common way to accomplish this is via a server-side process that will create 
your RTF file based on input from the Flex client application.  I've seen 
people do this kind of stuff with XLS among other things.

Subject: [flexcoders] converting to RTF in flex

Hi,

I have a concept of a "form" in my flex app.  I have this requirement
where we want to export this "form" into an RTF formatted file.  Has
anyone ever done this before?  Do you know of any flex capabilities
that could assist me in implementing this?

Thanx,
George
