Multiple HTTP Listeners

Hi!
In Oracle 9i db release notes:
"2.9 Starting Multiple Oracle HTTP Server Listeners on the Same Windows NT Computer"
It works fine, i've got one problem:
When i start an apache server from command line,
it brings up a Command Prompt window, and it's
on there, while the server is running.
Is it possible to start apache from command line,
without a window?
Of course, i need this feature, because i have to
run 2 instances of it.
(I've got XP pro)
Thanks:

Hi,
how to configure single HTTP server to listen on multiple ports? We have Oracle 10gAS installed RHEL 3.0 AS and changed the default port number from 7777 to 80 using the ias admin console and its working fine. But we want the 7777 port also to be active and listening so that whenever a request comes to either 80 or 7777, it should be handled by the single HTTP server which comes by default with the Oracle 10g AS.
Any kind of help would be of great help for us.
Thanks,
Balakrishna.

Using Multiple Event Listeners

Hi,
I have a movielcip (A) class in which I have used a Tween class effect on a child movieclip (B) scrollRect. The (B) Movieclip in turn has several movieclips whose have tween class effect being executed on thier child movieclips.
the tweens are all unique to each movieclip
and the event listeners are taken off once completed.
This works all well and good in FLASH IDE...
My problem arises when I try to view this in a browser on a Windows XP
it doesnt work in
Opera Version 9.63
Firefox 2.0
and Google Chrome 2.0
The only browser it works fluently in is
Internet Explorer 7.0.5
What is happening in most cases it that the animation appears to "stick" but i think what may be happening is the listening or removal of the event listeners. The animations are left incompleted.
Is there any rule of thumb when using multiple event listeners?
here is a snippet of some of my code
on click event from movieclip (A)
private function scrollToSlidePrev(e:MouseEvent) {
               if (((slideIndex - 1) >= 0)) {
                    nextButton.mouseEnabled = nextButton.enabled = previousButton.enabled = previousButton.mouseEnabled = false;
                    var position:Number = 0-SLIDEAREA.width;
                    var slide1:TileListSlide = slides[slideIndex] as TileListSlide;
                    var slide2:TileListSlide = slides[--slideIndex] as TileListSlide;
                    scrollSlide(position,slide1,slide2);
tween animation in movieclip (A) on (B)
private function scrollSlide(pos:int,slide1:TileListSlide,slide2:TileListSlide) {
               slide1.resizeSlideTo(0.6); // execute tween on child movie clips in B
               slide2.resizeSlideTo(1); // same as above;
               var rect:Rectangle = sliderMc.scrollRect;
               var tween1:Tween = new Tween(rect,"x",Regular.easeOut,rect.x,rect.x + pos,3,true);
               tween1.addEventListener(TweenEvent.MOTION_CHANGE,setSliderScroll,false,4);
               tween1.addEventListener(TweenEvent.MOTION_FINISH,toggleButtonEnabled,false,3);
tween animation in movieclip (B) children
public function resizeSlideTo(sc) {
               var m:Matrix = tileList.transform.matrix as Matrix;
               var p:Point = new Point (m.a, 0);
               var tween2:Tween = new Tween(p,"x",Regular.easeOut,p.x,sc,3,true);
               if (numericStepper != null) {
                    if (sc != 1) {
                         numericStepper.visible = false;
                         tween2.removeEventListener(TweenEvent.MOTION_FINISH,showStepper);
                    if (sc === 1) {
                         tween2.addEventListener(TweenEvent.MOTION_FINISH,showStepper,false,2);
               tween2.addEventListener(TweenEvent.MOTION_CHANGE,setScaleOnScroll,false,3);
here is the link
http://visual_admin.web.aplus.net/ticker/ticker_widget.html
the effect disables and re-enables the buttons when its done.... then the listeners are removed.
each one with the exception cretes its own unique tween (obviously this is a custom class built as each clip)
i really don't know what to make of it guys

apparantly making the tween a property of the class rather than a random variable in a function worked.....go figure

HTTP Listeners shown as running but can't stop, start or configure

In 4.0.8.2 Oracle Application Server Manager Enterprise
Edition, HTTP Listeners, for the "www", the listener shows as
down but is actually running. If I try to stop it, it says it
is not running (the IE dialog box pops-up). If I try to start
it, it says (in a new small browser window) "OWS-08806: Oracle
Web Listener 'www' is already UP and running at pid 0." Since
my site is up, I know it is running. However, how can I bring
it down?
If I look at the Http listener views it shows both admin and
www listeners are up and shows pid's for them. But when I go
to them individually they say they are stopped as I said above.
I use Oracle Application Server Manager 4.0 to view the HTTP
Listeners configuration. The Oracle Application Server Manager
4.0 looks like this:
- name of the site
+ Oracle Application Server
- HTTP Listeners
- host name: admin
Network
Server
etc
When I click on, for instance: NETWORK, it supposed to show me
the properties after prompting for a username and password. But
it just didn't do anything showing page not found.
Any assistance would be greatly appreciated.
Thank You!!!

Thanks again.
I'll try to be more clear about my current setup:
Modem
->
Router
DHCP enabled but supplying server with static ip of: 192.168.1.2 - hence my Ethernet 1 settings on my Xserve. The DHCP address the router supplies to other devices range between 192.168.1.101 - 192.168.1.150 (this is temporary). I'm using the Router as a temporary network connection for devices as I continue to setup the server. Once the server is completed, I will hook everyone up through the switch.
->
Xserve
The Xserve receives a static IP from the router above (192.168.1.2) even though the router gives DHCP addresses to other devices. The Xserve then goes out Ethernet 2 to (which has also been assigned a static internal address: 192.168.1.3) a switch.
->
Switch
The Switch definitely has DHCP disabled, and merely extends the network connection.
Right now, the Xserve is doing nothing other than attempting to supply an internet connection to devices attached to it. I performed a clean install after a day or two of troubleshooting.
I really want to be able to control content access as well as give certain devices priority over others using the Xserve. I want it to control... the network, in all aspects: DNS, Open Directory (Master), Firewall etc. Am I still able to control the network with the Xserve if it is hooked up side by side to the clients without reconfiguring my router to hop through the Xserve before going to the internet? If not, why not just use the Xserve as a middle man as I currently do?
What are the benefits of using it side by side to the clients? What are the drawbacks of my current setup? (Other than it not functioning)

How best to make a transaction span multiple HTTP requests?

Hi, all. What is the best way to implement a transaction that spans multiple
HTTP requests? Many J2EE applications must solve this problem, but I can't
any guidelines for an implementation.
Consider an application that implements a multi-step wizard. Each step
gathers data from the user; step one gets the user's name, and step two gets
his dog's name. When the user completes the wizard, the application saves
the user & dog in two entity beans. Conceptually, the application treats
this wizard like a single, long-running transaction. The transaction begins
when the user launches the wizard. Submitting the JSP for step one adds the
Boy bean to the transaction, and submitting step two adds the Dog bean.
Finishing the wizard commits the transaction. Exiting the wizard or timing
out causes the transaction to rollback.
Although the wizard looks like a transaction, the entire sequence of user
interactions can't be captured in a single JTA UserTransaction. A
UserTransaction must be associated with a single thread, but each wizard
step is handled asynchronously by its own execution thread. It's impossible
to funnel the conversation through one thread that can demarcate the
transaction. (This would be a pretty dumb solution for other reasons, but I
don't want to get lost in details.)
I think the standard way to solve this problem is to store conversation
state in a stateful session bean (or the http session) and create / update
both entity beans in a transactional EJB method after the wizard completes.
Unfortunately, this solution prevents me from leveraging a lot of great
transaction management features provided by the app server. For example, I
can't use optimistic concurrency to make sure that the dog object hasn't
changed in the database between the start and end of the wizard. Also, I'm
forced to keep track of changes to the dog object in the conversation state,
then replicate these changes to an entity bean at the end of the wizard.
Keeping track of state in a stateful bean is pretty straightforward, but it
seems like there must be an existing solution that leverages the appserver's
concurrency and state management features. Am I missing something? Is there
code, a pattern, or an article that describes the best way to implement a
multi-step process that looks transactional? I suppose WLI does what I want,
but that feels like killing a roach with a SCUD missle. Thanks for any
advice.

I assume from your answer that I'm on my own for implementing stuff like and

usual pattern is when you're pushing the JavaBean back to the CMP you
call all the setXXX methods on the CMP bean. Our CMP container will
check if the value you are setting is the same as read from the db. If
so, it will not update that column.

I'd recommend that you include a separate version or timestamp column in
your db schema.
Then do something like this:
Client Server
1) First HTTP Request
2) Read current Dog and Boy Entity Beans
(if any) and copy their values into a JavaBean.
You want to include the version
column(s) in the JavaBean(s) along with the data values.
You probably also want to store the JavaBeans in
your HTTP Session.
3) Client proceeds through wizard interacting with JavaBeans
4) Finish with Wizard, copy JavaBean values (including
version columns) to CMP 2.0 Entity Beans.
The version column will give you the optimistic concurrency protection
that you desire without opening a JTA transaction to span user input.

Creating multiple http servers on one machine

I created multiple http servers on one machine.
I did this in the following way:
Created a http service as nt service with the following command:
apache -i -n Testservice -f d:\oracle\isuites\apache\apache\conf\httpd2.conf.
When I start the service, I always get an error:
Didn't return an error. Cannot start service.
Can someone help me.
I need two httpd services as nt service. Because, I want to use oracle fail safe. So I need a service.
Alternative : I can create batch files. But I want to start these batch files as nt service. Is there a possibility on
Windows nt to do this, or an available tool.
Thanks in advance,
Iloon

          If you want to have multiplie servers in the same machine and you want to cluster them then you need ip for each instance.
          If you want multiple instances without clustering, then you can have them run on the same ip but each one should have a different port.

          If you are accessing the ejb/services on the same server using a servlet. You can get the context, simply using the default getInitialContext(). This should return the context to the local machine. This shoudnt require any ip information.

Oracle iPlanet Web Server - HTTP listeners based on hostnames

Regarding the HTTP listeners configuration I read:
IP Address — A Valid IPv4 or IPv6 address. “” implies that the HTTP Listener will listen to all IP addressed for the configured port.*
(no mention to hostnames)
I have tested that it is also possible to specify a NAME in the IP Address field and the effect is the same if I specify the explicit IP the name is associated.
Is it a supported but not documented feature ?
In other words can I use this feature for my deployment ?

It seems like I was wrong, you can not use hostname in <ip> element. Code doesn't try to convert hostname to <ip> address.
When you said that it worked for you, can you show the output of "netstat -an | grep <listen_port>".

I'm not sure what you mean by the "like" commands, but if you
just use a
repeater to repeat your buttons and use ONE HTTPService that
looks at what
index the button that was clicked is in the repeater list and
sends based on
that, I'd think you'd be pretty much there.

Multiple http connection

is it possible for me to make multiple http connection to server?
I'm trying to send data for about 40kb, i send the data into 80 parts ( a part about 500 bytes)..
is it possible to make about 80 thread in the same time??
I do this way to reduce time consumption...
Help me please..

No, in this case, more threads will most likely slow down the data transfer:
- more threads means more TCP connections, means more overhead
- CPU scheduling will make it slower than using one thread, they can't work symultanious anyway
- One thread is probably already capable of fully filling the network bandwidth with data

Http-listeners on 0.0.0.0

Hello...
I've installed j2eesdk-1_4_2005Q1-linux successfully on a machine running several nics. I removed all http-listeners and created new ones assigning them a specific IP-Adresse. After restarting the domain, the server still listens on 0.0.0.0 (according to netstat) and not on the fixed IP. I've also tested creating two http-listeners with different IPs listing on the same port. In this case the server randomly displays data of the first or second virtual server.
Is this a bug? How do I tell the app-server to only listen on a specifc IP-Address and not on 0.0.0.0?
many thanks in advance ...

Many thanks for your answer but I had already read that document. I removed all standard listeners and created a new one. In the "Network Address" field I entered a valid IP. Actuallay I thought, the server will only listen on the entered IP but it continues creating a listener for 0.0.0.0 making it impossible to create several listeners with the same port on different IPs.
I'd like to create a configuration shown in figure 15-4 of
http://docs.sun.com/source/817-3652-10/agvirt.html#wp1021931, but the app-server always uses 0.0.0.0 for listening.

Multiple HTTP requests using single HTTPService component

Hi,
I am having one requirement, I need to use a single HTTPService component to send request to a same and single ASP.net multiple times.
How can I acheive that..? I know that I can acheive this by sending one request at a time and after the "result" event is called for the first request then sending the second request and so on...
But if I do so then it will be delayed response as I need to wait until the result handler for the previous request is called...
So how do I do this..?
Any help greatly appreciated....:)
Thanks in advance..
Thanks,
Bhasker Chari

yep, the setting works when set to 10. Seemed to not work when set to 20. Anyways, summary is "long polling" and Flex
or Flash are not good compatriates. So, you will need to work out your own mechanism on the server or client
side to limit the sockets used/wasted. Painful but true.

Multiple HTTP requests through same connection

Hi...
I am writing an application which connect to its server through HTTP protocol and the server is basicaly a bunch of servlets hosted somewhere (Right not it in the tomcat running in my PC)
I know that with Connection Keep-Alive header you can keep the connection alive and do multiple requests from the same server.
Can some one point me to where can I find some sample code which shows how to send multiple requests through same URL conection or URL object. What i cant figure out is how to reset the URL connection or its streams a and make them send anotehr request message to the serverso server can respond.
Or do I have to do this manualy (using sockets)

You SHOULD be able to do a HttpUrlConnection method. However, I have hand-coded HTTP server and client apps and the keep-alive is rarely enabled in servers.
This is due to better handling of millions of unique hosts requesting, unlike a network os, which is made the other way around.

Multiple HTTP Servers, 1 for HTTP and other for HTTPS

I am trying to install 9ias 1.0.2.2.2 on 2 machines both running solaris. 1st machine hosts the database (8.1.7.4) and the other hosts the App server (9ias), what i am tryin to achive is have 2 listeneres. One for HTTP traffic and other for HTTPS traffic. Have anyone configured this and could shed some light and enlighten me.
With all the notes i have read i have understood that i need to basically install 2 instance of Apache in 2 different Oracle Homes. but my question is how can i just have one portal repository. or rather i should say if somebody could guide me from installing the 2 instance of Apache.
Thanks
