What would be possible reason for this? any solution or check we need to make in our application.

I didnt get this line
>>Seems to me it means that an attempt was made to use a channel that's already closed by another operation. Did you re-use resources?
what is channel? how channel is closed by another operation? what kind of resources?

You made a connection to another application; I call that a (virtual) channel.
Did you use such a connection (object) a second time?
;JOOP!

;JOOP!
Do you have the complete stack trace?
I feel, there should be another error on the lower half of the stack trace.
There might be a statement "Caused By ...(another Error)".
giving the stack trace of error might help.

We user oracle 9i database. There we use Connection object.
Here is caused by Stack Trace.

Are you saying other application[which are possible application?] gone away
without giving us final message.
Basically in my application I am hitting to external urls to get the information, timeout is
3000 ms.
It is possible that it is happening in this case.

Well, there's all kinds of communication:
With a time server, without being asked for it, it gives you a timestamp and goes away instantly,
with a 'question server', it waits for your call, answers and then goes away instantly,
with dialogue servers, you open the 'rally' with a question and finally close when you're done.
So, what's the nature of this communication of yours?
;JOOP!

ya I am using response.sendRedirect in some of jsps.
ASKER
I am reading external URL which gives xml and parsing that xml
part of code is
socket = new Socket(url.getHost(), port);
socket.setSoTimeout(3000);
Writer writer =
new OutputStreamWriter(
socket.getOutputStream(),
"US-ASCII");
part of code is
socket = new Socket(url.getHost(), port);
socket.setSoTimeout(3000);
Writer writer =
new OutputStreamWriter(
socket.getOutputStream(),
"US-ASCII");
From the (sparse) comment in the APAR description, it sounds like the code that was seeing/causing the error was in the Administration Console where it tried to access the connection after the redirect was done. Hence, they attempted to use a resource that was invalidated (connection was closed) because of the redirect.
ASKER
so what kind action should I can take?

After redirect there is always new request, new connection. I am not using same connection after redirect. In JSP we dont hit database...through service-daolayer we hit database.

As actual solution was not provided, I am awarding points just for information.
I'm sorry that no definitive solution was provided. Thanks for the assist.
Good luck & have a great day

When accessing external resource, the data retrival purely depends on the volume of the data and the request IO Connection time out.
It is good to check the request time out value and see if the exception is occuring after the timeout period. If so, you need to increase the time out.
In Websphere environment the value set to 60 seconds by default.

Seems to me it means that an attempt was made to use a channel that's already closed
by another operation. Did you re-use resources?
;JOOP!
