How to detect when service is down?

During the LCCS service outage this morning, when my app was launched it seemed to just hang on the service login (saw same behavior when I logged into my developer portal account).
I am currently checking for exception generation around the session login call and have a callback registered for the error event. Is there something else that I should have in place which would have been able to catch this so that I can display something meaningful to my users?
Thanks

OK - another request related to the status of the LCCS service. I have been using health.acrobat.com and watching the corresponding rss feed in Google Reader to keep track of scheduled maintenance events and service outages.
I am trying to track down an older log entry where a call to keepalive on the Ruby AccountManager object generated a 403 which was logged on our side yesterday, Thursday 2/18 around 4:40pm PST. I am trying to figure out what could have caused the problem, but didn't see anything from the rss feed indicating that there were any recorded problems yesterday.
(1) Is there another resource that I can be checking to help in troubleshooting these sort of errors when we are unable to make connections to the service?
Thanks - Chris

How to detect when 2 movie clips have been clicked?

Hello:
I'd like to know how can I detect when 2 movie clips have been clicked (irregardles of the order).
What I have is this:
In my main timeline I have 2 independent movie clips (mc_him and mc_her) each in it's own layer that, when clicked, play an internal animation without moving my main playhead anywhere. What I need to do is, once they are both clicked (as I said, it doesen't matter in what order), a button that sends me to another section of my movie has to appear. It really doesen't matter if the button shows by enabling it with alpha or by sending me to a specific frame where my button lies. What I need to detect is both clicks so that the button shows up.
How can I achieve this?
Thank you very much.

btn1.onRelease=function(){
// do whatever
this.clicked = true;
checkBothClickedF();
btn2.onRelease=function(){
// do whatever
this.clicked = true;
checkBothClickedF();
function checkBothClickedF():Void{
if(btn1.clicked&&btn2.clicked){
// do something. both clicked
// reset both clicked properties?

How to detect when a page is in view with jQuery or javaScript?

Is there a way a detect when a page is in view? Currently it seems that my document ready function is being called when the page is the next or previous page as well as the current page. Seems that this gets called twice... is there a reliable way to detect this?

I ran into this alot. first thing is that when you are looking at a particular page, DPS is caching the pages around it, all around it, so it caches the top, right, bottom and left pages, which will launch things and play videos and what not.
Here's the workaround for getting it to only launch when in view. set the autoplay time (I assume this is for a "webcontent overlay") to .125 seconds. it will start the clock only when the page (tile) is in view.
don't know if theres an easier way, but that's how I do it and it works.

How to detect when new record is created?

How can I detect when new record is created in PA30? For example, a newly create record for infotype 6 (address).
Can I get the information in PCL4?

Hi Irene,
the field PAnnnn-AEDTM, nnnn is the infotype number, will give you the date when the record was last changed.
Not sure if you can precisely get the date when the infotype was created. I dont feel the need to read cluster form the same.

How to detect when a tile fails to load

We currently use SSRS to generate maps w/ custom layers and data. The requests made by SSRS to the Bing Map system occasionally fail when creating PDF versions of the reports under heavy load. I am looking for a way to work around SSRS's limitation
when using Bing Maps.
One approach I am exploring is to create a system that generates my own map images using the Bing Maps Api directly rather than being dependent upon SSRS. However, i can imaging that at some point a request to Bing Maps will result in a failure. Either
the system was unavailable or the request for the map tile timed out.
I would like to be able to detect when a tile failed to be received.

Hi Z3M,
Thank you for your question.
I am trying to involve someone more familiar with this topic for a further look at this issue. Sometime delay might be expected from the job transferring. Your patience is greatly appreciated.

How to detect if Database is down when client application is running?

Hi,
I have a oracle Forms application accessing a remote database. While doing processing, application has to post some data in a remote database.
As of now, when the Forms client is running and remote database is down, the client hangs.
I have tried Creating a timer before remote database procedure call in the FORMS Trigger and checking in the when_timer_expired trigger, if a specific duration has passed or not. This doesn't work as timer fires only after the remote procedure call completes and other SQL statements in the FORMS trigger where i have created the timer completes.
I Know sqlcode -3113 can be of help.
Hope someone can help me with a solution/suggestion.
Thanks
Hari

interesting situation.
what about issuing the select count(*) into cnt from dual, if cnt>0 then do post.
better to setup the remote database has fail-over to another node.

Data service ONLYT to retry NOT to failover when service is down

Hi All,
I have around 10 services to be clustered under 3.2 with network aware agents; normally I use scdbuilder to create agents.
There is few services, which I want them to stay down if they fail in the running node.
Let say I have service1 - running on port 2000, If port 2000 is down, I want advice it to restart this, failing the restart I want to make it START_FAIL, rather than switching to other nodes and try to restart there.
Is it possible to achieve this thru Sun Cluster 3.2
Thanks for the time,
Aruna

Hi Detlef,
Many thanks, I was reading about failover mode property - RESTART_ONLY, I guess It should work becoz my data services are build from scdsbuilder, so they should use DSDL. I will test it.
Thanks again,
Aruna

Add a mouse motion listener to the tree, and check the node at the mouse location.
Then change the icon of the tree accordingly:
tree.addMouseMotionListener(new MouseMotionAdapter() {
    public void mouseMoved(MouseEvent e) {
        JTree tree = (JTree) e.getComponent();
        TreePath path = tree.getClosestPathForLocation(e.getX(), e.getY());
        Rectangle bounds = tree.getPathBounds(path);
        if (!bounds.contains(e.getPoint()))
            System.out.println("No tree node under mouse");
        else {
            TreeNode node = (TreeNode) path.getLastPathComponent();
            System.out.println("Tree node under mouse: "+node);
});

Detecting when user clicks title bar of TitleWindow

I am just beginning to dabble in Flex and am loving it so
far. I can't seem to figure out how to detect when a user clicks
the title bar of a TitleWindow. Could someone please give an
example of the correct way to detect this? How do you tell the
application to dispatch an event only when the title bar is clicked
and not the contents of the TitleWindow.
Thanks!
Josh

Subclass TitleBar and add a mouseDown event handler to the
protected titleBar property (of type UIComponent). That event
handler will execute when a person clicks down in the header.

How to detect is response deliverred to the client?

Hello everybody...
I have problem and don't know how to solve.
My server application runs on apache tomcat 5.5, and deals with some important data transactions.
After getting the request, server has 5 sec. to send response, after that clients will close their sockets.
The connection can be very slow, (GPRS), so it is very possible that transaction will not be over in that time.
I need the way to find out, on my server side, when response isn't get to client in 5 sec.
Is there any idea how to do that?
Sorry if my English is not so perfect.
Thanks

Yes, but that way of write timeout means that write have 5 sec to send buffer to the underlying protocol.
I can't know if TCP succeed or not to deliver data in that short time. I think write is asynchron.
Problem is how to detect when client is disconnect and data are not delivered.
Once again, sorry if my English is not so good.

How to detect the content of a Loader?

well if you are using the MCL you can set up a function to
handle the loadError event and trap the error and print it out or
stick a default image in it's place. read up on the moviecliploader

Detect when play audio is done.

Hi,
I use this javascript function to play my embed sound file:
function PlaySound(soundSrc) {
var thisSound;
if((!document.all)&&(document.getElementById)){
thisSound = eval("document." + soundSrc);
thisSound.Play();
else if(document.all){
thisSound = eval("document.all."+ soundSrc + ".src");
document.all.sound.src= thisSound;
else
return;
It works good. Now I need to do something right after sound file is done playing. Can somebody tell me how to detect when sound file is done playing?
Thank you,

Hi,
a Google search doesn't bring up an event being reaised on stop. So I guess a timer is what you should consider using.

Detecting when user closes browser or moves to another site

How can detect when a user has closed the browser or moved to another website

No, it doesn't automatically fire any request to the server or so. Best what you can do at the server side is intercepting the session destroy using HttpSessionListener. You can also let Javascript fire a (ajaxical) request to the server side notifying that the onunload/onbeforeunload has occurred.
Difference between onunload and onbeforeunload is by the way that the onbeforeunload can still prevent the page actually being left using a warning message like "are you sure to leave page?" and that it is NOT supported by w3 specification and thus not guaranteed to be supported in all webbrowsers (as far under each Opera -which very strictly follows the standards- doesn't support it).
