How can a JMS Listener Notified get when a Topic Server Goes Down?

I'm in the process of looking into pub/sub model for a centeralized data source where vertical applications subscribe to a topic to get updates on person demographic information.
          I was playing with the JMS topic examples and noticed that when I have a Durable Subscriber listener (java main) and the topic Server goes down. It never gets notified. When I restart the Topic server and send msgs to the topic, the Durable Listener doesn't get them.
          Once I restart the Durable Listener (java main), it receives all the messages that were pending.
          I implemented the ExceptionListener and it never gets a shutdown msg either. I shutdown the Topic server via Ctrl-C, Graceful Shutdown and Forced Shutdown.
          Is there a way for the client listener to determine when the Topic Server went down, came backup, and restore the connection to it automatically? Or do we have to implement some type of ping mechanism on the client listener and re-create the connection ourselves?
          Thanks. Later...

Hi Wayne,
          I think the exception listener should have fired. Some comments/questions:
          - Does your app call "connection.setExceptionListener" in addition to implementing ExceptionListener?
          - Which version and maintenance/service pack are you using?
          - Is the client using the wl* "thin" client jars or the "thick" client jar?
          - Version 9.2 provides an automatic reconnection capability for consumers. This behavior isn't enabled by default due to natural side effects that some apps might not be prepared to handle (needles to say, I recommend reading the doc thoroughly).

How can I visit the performance tab when the target DB is down?

Hi, All:
I wonder if it is possible to visit the performance tab when the target DB is down. I thought it should be possible. But whenever I first click the performance tab, I will be asked to enter the user/passwd for the target db(I have set the preferred credentials).
Furthermore, is it possible to analyze the history sql/performance if the target db is not startup? and how can I do it?
Thanks in advance

I have seen other postings by the same ID and my suggestion is that you have a look at the Enterprise Manager Documentation Library. After that, you can ask questions relating to subjects you cannot solve with the documentations.

How can i do with labview program,when i have 20 different values,and 1 want to add it with constant value.and how to get the results?

how can i do with labview program,when i have 20 different values,and 1 want to add it with constant value.and how to get the results?

Why do the 20 values have to be different? The same code should work even if some are equal.
What do you mean by "get the result"? The result is available at the output terminal and all you need is a wire to get it where you need it. That could be an indicator, another operation, or even a hardware device.
What is the data type of the 20 values? An array? A cluster? A bunch of scalars? A waveform? Dynamic data?

How can I fix the crop? When I crop my photos and click okay, the layer no longer shows the resulting photo -- just a dark gray background.

Can anyone help me to resolve my cropping issue? I have either hit a key I wasn't supposed to hit accidentally, or the software needs to be fixed or reset. And if I reset or reinstall the software (Photoshop Elements 10 + Organizer), will all my categorized photos in the Organizer be lost with the new installation?
I have three screen shots to help show my problem.
The first one is the page before I make any cropping edits:
This next one shows the beginning of making the crop, before clicking the green check mark to accept the crop. Notice the photos are still intact and visible in the layers:
And when I accept the crop (by clicking the green checkmark), below is the view of my resulting new layers (the photo is no longer there):
As you know, what I should see is the resulting, cropped photo in both layers -- not a grayed-out set of boxes.
How can I fix this to get the crop feature to work again?
Thanks in advance for your help!

How can I populate a date field when document is signed?

I have 4 digital signature fields in a PDF form. Next to each signature field is a date field (m/d/yyyy format). I would like it so when the user signs the signature box that the date field next to it populates with todays date, then changes to read only (so it cannot be altered).
In Adobe Acrobat Pro 9 I have this form and it has the following fields
Signature1
Signature2
Signature3
Signature4
DateField1
DateField2
DateField3
DateField4
The Signature fields trigger a Topaz.GemSignPlus driver where the end user will be signing on an electronic signature pad.
How can I use Javascript to detect when one of those Signature fields is populated and then fill in the date to the approrpiate date field? I tried creating boolean variables initialized as false for each sig field. Then when the signature is done I try to change it to true, but for whatever reason my javascript detecting the value doesn't do anything.
I've searched the net endlessly for this solution. I can't believe I'm having such a hard time finding an answer. I mean how many places do you go where they ask you to "Sign and date here". Every signature based document I've ever seen also requires a date.
Anyway here's what I have. In Document JavaScript functions I have a script name called populate date:
function populatedate()
var bSignature1 = new Boolean();
var bSignature2 = new Boolean();
var bSignature3 = new Boolean();
var bSignature4 = new Boolean();
if (bSignature1) {
    DateField1.value = util.printd ("m/d/yyyy", new Date());
if (bSignature2) {
    DateField2.value = util.printd ("m/d/yyyy", new Date());
if (bSignature3) {
    DateField3.value = util.printd ("m/d/yyyy", new Date());
if (bSignature4) {
    DateField4.value = util.printd ("m/d/yyyy", new Date());
In each signature field I have under the Signed tab "This script executes when field is signed:
var bSignature1 = new Boolean(true);
I'm trying to change it to true see. My thinking is if its true than DateField1.value should print the m/d/yyyy in it from the built in Date() function.
But maybe I am not getting this context correct. I am new to Javascript in Adobe.

It's quite a round-about script... Why not simply use the signature signing script to set the value of the date field? The correct syntax for that is:
this.getField("DateField1").value = util.printd ("m/d/yyyy", new Date());

Thanks for the help. The restore seems to have solved the problem. I had a bit of a panic attack when things started going haywire and the Apple 'Support' told me to call back during business hours!

HT5105 How can you do picture in picture when you are working with a Multicam clip?

How can you do picture in picture when you are working with a Multicam clip?

Im doing a drumming music video and with the multi cam clip all the angles are nicely sync'd top the audio.
Problem is if i want to have 3 angles on top of the main shot, im gonna have to re-sync them all to get them to line up manually. If i could use the multi cam clip they will already be aligned
Thanks for trying to help appreciate, hoping someone has some multiclip knowledge and will be able to tell me if yay or nay.
