Heavy data push

we have this requirement to push some heavy messages from server to flex client.
what are my options ? currently we are investigating blazeds.. but looks like it has some performance issues. is that true ?
our message rate is high. flex client is expecting to receive atleast 3-5 messages a second.
is there a way to push messages to client directly without using blazeDS ? i read somewhere that you can do this with using some security policy files on server side ? what kind of performance we gain if we use this approach ? any issues if we decide to go this route and eliminate the whole blazeDS ?
one more question about blazeDS. ? what kind of security does it have ? can i make some secure messages that only particular consumer gets and not other should be able to even see that messages ? (like JMS queue.. send secure message to only one consumer) ? how can i achieve this using blazeDS ?
any good tutorial or any infomartion would really help ..
Thanks a lot.

yes you can't change battery and display on software because it's hardware may be release another model aspect your requirement from blackberry ok!

Server/Data Push Form Java to Flex.

Hi All ,
In my application ( Flex3 + Java Struts) i am using RPC (HttpService) calls only . Recently i read the article about
DATA PUSH FROM JAVA TO FLEX WITHOUT PAGE REFRESHING USING SERVER PUSH.
Can anybody tell me more about this , how to use this in my application.
Thanks in Advance....

Did not worked that much with those but I know there are some embedded example
that comes along with the blazeDS download.
The DB is embedded but you can have a rough idea. alsoe there are some
turtorials and odcs for both of them, Google is your friend. Also google for
James Ward's blog and Christophe Coenraets, they have posts about this.

Data push in flex

Hi
I am working on data push in flex!
I am using consumer component in flex to subscribe to server to receive the data push by it!
Data push is happening for sometime and when I switch to other browsers and come back consumer is not listening to the data sent by server but I can see the logs in the server. let me know any poitnters regarding this?
Find the piece of code below...
<mx:Consumer
id="cameraControlConsumer" destination="deviceDataFeeder" message="messageHandlerForCameraControl(event)" fault="faultHandler(event)"
/>
private
function faultHandler(event:MessageFaultEvent):void{
Alert.show(event.message.faultString);
private function messageHandlerForCameraControl(event:MessageEvent):void {
var msgSender:String = event.message.headers["USR_LOGIN_ID"].toString();
if (msgSender == myModel.loginUserId.toString()) { tempObj =
new ObjectMap(event.message.body as Object);tempMap = tempObj.getHashMap();
if (null != tempMap) {
var tempVar:String = tempMap.getValue("vmsDeviceId");
if(tempVar != null) {selectedCameraId = tempVar;
else {selectedCameraId =
null;}
if (1 != getStatus(selectedCameraId)&& selectedCameraId != null)
{disableCameraControl(
false); tempVar = tempMap.getValue(
"MdviZoomMax");
if(tempVar != null){
maximumZoom = int(tempVar);
tempVar = tempMap.getValue(
"MdviZoomMin");
if(tempVar != null){
minimumZoom = int(tempVar);
else {disableCameraControl(
true);}

Hi
Yes the the most bugging problem, took lot of time to debug this.
check web.xml file in your server, need to set session time out property as below

 <session-config>
 <session-timeout>120</session-timeout>
 </session-config>
Set '-1' for session to be continuous...
Thanks and Regards

Fast online processing and heavy data crunching in cluster

Hi,
I have a Coherence cluster and two types of operations I need to perform:
1. Lightweight online processing e.g. updating user profiles etc. This type of processing is invoked by web application and must be very fast, so that application is responsive for the users.
2. Heavy data crunching (data aggregation). This type of processing must occur on hourly basis.
Both types of operations work on the same data.
I would like to minimize the impact of data crunching on online processing. What is the best way of doing it?
Is is possible to "dedicate" part of servers to do the fast, online work and run heavy tasks on other part of cluster?
I can imagine using active-passive sort of architecture, where data crunching is done on passive cluster. Is there any other option, avoiding active-passive pattern?
Best regards,
Jarek

Hi Jarek,
It may be simpler to use different services to dedicate different servers to different tasks, for example:
cache-config.xml:

* dimitri Feb 22, 2010 7:28:39 PM
public class MyCacheStore extends MapCacheStore
 public MyCacheStore(String sCacheName)
 super(CacheFactory.getCache(sCacheName));
 }and run servers dedicated to online processing with -Dprocessing.localstorage=true -Daggregation.locastorage=false and servers dedicated to aggregation with -Dprocessing.localstorage=false -Daggregation.localstorage=true.

Data push problem

Hello,
I've implemented Data push using the amfstreaming channel. But, the client keeps on polling to get the data every 3 seconds,(blazeds does it I guess). The product which we develop will have more than 1000 users hitting the server, The blazeds model is obviously not good in this senario, which is the better way to implement the data push? Sockets? or Blazeds? Or any other way? And we are not in a position to buy the LCDS .
Thanks in advance!

I am using sockets for a data push. I dont have 1000s of users but I have around 50 scanning stations that are scanning thousands of barcodes per day, have no problem at all.

Data Push

Hi,
When it comes to data push in coldfusion everyone start talking about Live cycle and BlazDS, but looks like those 2 products can't work unless you use Flex , Flash or AIR, looks like it can't update just a simple div content on a web page, I saw one example which use a third part server http://pusherapp.com/ to make the data push!!.
Can't ColdFusion just do a simple push without using Flex ... etc or a third party server, any example??

The app you mention only works on HTML5 (which hasn't been released yet), and indeed it falls back to Flash on browsers that don't support HTML5.
The fact of the matter is that most people can't use HTML5 features yet because it's not widely supported (by that I mean: it's not supported on IE, which is the browser the bulk of people use, whether we like it or not).
Also, looking at this - http://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28HTML_5%29 - general HTML5 support aside, it seems that web sockets are hardly supported on any browser at all, as yet.
So it would be a poor use of resource for CF to include support for this sort of "edge case" just yet.
And even after HTML5 is released, it will be quite a long time before it has the ubiquity necessary for this sort of solution to be a sensible approach. IMO.
The current best option for push-capable applications is... Flash. It does have the ubiquity (some niche Apple products aside ;-)

Iphone 6 heavy data usage

I bought my iPhone 6 in the States late last year - unlocked and sim free. While in the states on a pre pay sim, data use was as expected, I am not a heavy data user on my phone.
Back in Europe, I used my Belgian pre pay sim with much the same result as the USA - no unusual data use.
Get to England and put my Vodafon pre pay sim in and my data gets munched up before I know what is happening - 500mb gone in less than two days.
I always keep my apps closed when not in use, don't use cloud, all software is up to date.
My gut feeling is that the data use is only high on the UK sim. I have read lots of other comments about this problem from worldwide users but none give a definitive resolution, some blaming carrier updates, others suggesting resetting the phones from scratch. I spoke with vodafone who gave me some credit back on my data account (strangely enough - without me even asking for it or suggesting it) and have tried a phone reset but am now worried about putting the UK sim back in. The phone can easily munch through my data allowance AND an additional 10-15 pounds per day in extra data
Does anyone have any ideas or simimlar experiences

Brett
Thanks for the link - it has re-enforced how I already use my phone. I am seeing some strange things though - mapping and app store are the biggest consumers and look like the culprits that are sucking my data. I find this very strange though as the mapping service consumes the most but when I have no mapping apps open and I NEVER use the app store via my phone. Even when I turn them off as you suggested, they still consume data.
I regularly close off all apps by double tapping the home button and then swiping the app up. I never allow apps to send me notifications, nor do I allow any app access to my data. I have a couple of apps that I allow access only while using them, Runkeeper being one such app but when I see their consumption it is always measured in Kb rather than Mb so that doesn't worry me too much.
I am currently turning off cellular data to stop the bleed but this means useful things like iMessage will not work for incoming messages.
I am sure there is something else being missed. Any ideas? Especially concerned that when I have disabled something in the settings, it can still continue to use data.

Audigy 2 makes "scritches" when making heavy data tranf

Hi everyone.
I've have a weird problem with my Audigy 2: When I'm making heavy data transfers between my dri'ves (I've seven of them...), the soundcard starts making very agrressi've noise "scritches" through the speakers, regardless of the player. It does that with MediaPlayer, iTunes, MusicMatcjh and PovwerDVD, so I'm pretty sure it's not player-related. It is also prone to make such noises when I go over the internet.
Now, in the normal course of my doings, I don't make huge transfers, so it's fairly managable. But when I tranfer big chucks of data (500+ Gb), it starts. It's particulary loud when I'm tranfering to another computer, either FiWi, USB or RJ45. And it occurs from any dri've to any dri've.
When I game, play movies, do PhotoShop, ANY usage, even highly demanding CPU processes, no problem. But if I simply move chunks of data from a dri've to the other (no problem in searches or seeking), it happens.
Any idea why so? My setup in a nutshell:
WinXP SP2, firewalled, antivirused and antispied
Various demanding games and applications
ASUS P4C800 Deluxe
,5 Gb DDRAM, 400 FSB
480 watt power supply
4 fans
x 60 Gb IDE
x 80 Gb IDE
x 80 Gb IDE, on Promise channel
x 20 Gb IDE
x 200 Gb IDE, on Promise channel
x 200 Gb SATA
x 300 Gb SATA
Audigy 2 Platinum
nVidia GeForce FX 5200
ATI RADEON 9250
I'm a but fuzzy on the brand of the HDDs, I haven't opened my case in a while, but I know I have Maxtor and WD dri'ves.
Any help would be glady appreciated.
Thanks!
Vaixe

- check if Audigy is sharing IRQ with IDE/SATA, NIC, FireWire, USB controller?
- check if DMA transfers for IDE channels are set correctly for best performance (if you transfer from IDE disks).
- check how antivirus program is set (if it is set to scan files when transferred).
- decrease graphic card(s) PCI latencies to 28 (you can do this with PCI Latency tool (if you do use your PC otherwise acti'vely (not just listening music) while transfering files).
- check if you have autoupdete(s) running/acti've on OS/other programs
these came into mind now ...

Issue having seperate data pushes for multiple email accounts

I've always had gmail set up through my phone. I love push and don't receive any issues using it.I recently added a 2nd, work email (exchange) to my phone. However, I'd prefer to manually check the exchange account while leaving my gmail on push. I can't seem to figure it out though. My best guess was to go:
settings>mail>fetch new data>advanced.
I have my gmail on push and my exchange on manual. I would assume the advance settings override the push and fetch settings on the primary "fetch new data" screen. However, nothing seems to be working the way I want it to. Sometimes my phone will auto-update my exchange, sometimes i'll get gmail belated, etc.
If anyone could please advise the proper settings for both the primary screen as well as the advance settings in order to have my exchange on manual and gmail on push.
Thanks

Note sure what G mail is, but if it involves another isp email provider not interested, I have multiple accounts as a garbage dump for spam possibilities too much spam on one account bye bye. Usually 2 main email accounts though. btw, not a memory issue either. still plenty left. Was looking at the contacts thread and there is receiving/sending issues with email since 2.0 update anyway.

Activation date pushed back twice

Hello,
I recently moved into a new flat and told BT 4 weeks in advance that I will be moving and I was told the line would be activated on the 27th of June. That day passed and only the phone line was activated. I called up and was then told that there was an issue with activating Infinity broadband so they gave me another activation date which is today. Today I called just to check if everything was fine and after about an hour of waiting in queues I was told that the order got "lost in the system" and that a new activation date has been set for the 16th of July.
Is this normal? How many times can they push back the activation date? Im considering cancelling my contract as it's becoming more and more frustrating. Can I cancel my contract if they haven't provided me with the full service?
I depend on the internet as I work from home and I've pushing back deadlines as I can't work properly without it. I already spent £80 on topping up mobile data and I just can't afford to keep working like this.
Has anyone had a similar experience? Can anyone give me some advice?

activation is by openreach who own the lines so regardless of ISP apart from cable you will need openreach to install/activate your connection.
as this is a residential line and is not supposed to be used for business purposes albeit many use it for checking business email and casual business use. there is therefore no consideration about loss of business. did you consider a business line which would give you a better level of service guarantee

There is a Blaze forum. Try asking there.

Service install date pushed back a month

After waiting approx. a month for my Fios install, I get an email three days before the initial install date saying that it has been pushed back, another 30 days.
I call to find out why, no one can tell me. I want to cancel my order, no one can help me.
FTTP is great, but Verizon is horrible.

Probably related the potential for a strike by the CWA.

Iphone 6 plus ship date pushed up!!

Although my original ship date was supposed to be 9/19, and was then pushed back to 10/7, I checked this morning and it was pushed up to 10/3. That is a little bit of good news! I can only hope it gets pushed up again!
A little less frustrating

I agree Wiugraduate17 it isn't exactly good news considering we were told 9/19 to begin with. But, I am still happy to see the date moving back just for the simple fact that I don't want to wait an additional month to get it. Verizon & Apple as well as all other mobile carriers knew that this was going to be HUGE. They knew everyone was waiting for a bigger and better iPhone. They had the knowledge to prepare, and didn't. It was a complete failure on their part. When customers are willing to pre-order phones in the middle of the night, they need to be able to fulfill the orders and make their devoted and loyal customers know it wasn't a waste of time.
