Failed session with Java Thread error message

Hi:
We are using Oracle Forms 10g (application server 10.1.2.0.2).
One of our users sessions just went unresponsive and when we took a look at the Java Console we captured the following:
Exception in thread "AWT-EventQueue-2" java.lang.IllegalStateException: cannot open system clipboard

Has anybody seen this before and found a solution for it?
I searched the forum and found nothing that seems to apply.

Bug 4520121 is about a java.lang.OutOfMemoryError or performance degradation when large amounts of data (megabytes) is on the system clipboard. Not sure if that's related to your problem as the call stack seems to indicate you're getting this when pasting information from the clipboard to an item
Update: searching on metalink quickly reveals Note 301618.1 which refers to the bug Jan mentions and also to "Bug 4290580 JAVA.LANG.ILLEGALSTATEEXCEPTION: CANNOT OPEN SYSTEM CLIPBOARD"
From the metalink Note:
The both bugs are fixed in 10.1.2.2 of Forms. In order to implement the full fix for Bug 4290580 / 4170518, the following modifications must be made:
1. formsweb.cfg:
a. Locate forms90/server (9.0.4) or forms/server (10.1.2)
b. Add allowAlertClipboard=true
2. Add the "allowAlertClipboard" to the following HTML templates used by Forms:
base.htm
baseie.htm
basejini.htm
basejpi.htm
* Syntax for the <OBJECT> </OBJECT> and <APPLET> </APPLET>
<PARAM NAME="allowAlertClipboard" VALUE="%allowAlertClipboard%">
* Syntax for the <OBJECT> </OBJECT>
allowAlertClipboard="%allowAlertClipboard%"
This paramter is added so that user has a choice of disabling the Clipboard alert Dialog is added so that user has a choice of disabling the alert Dialog by setting this parameter value to false in case of System Clipboard is used by some other Application.

Pages failing with Java Heap errors

We are running CF 8,0,0,176276 on a Windows 32 bit 2003
server, with IIS 6 and Java Runtime version 6 ( it's really version
1.06).
We started getting the java heap error messages two weeks
ago. Now we are also getting the 'GC overhead limit exceeded'
error, which is concerned with the Java garbage collection. I tried
to change the JVM heap size from 1GB to 2GB, but CF wouldn't start
up. I've since found out that Windows 32bit servers can't use 2GB
for Java.
One java article I found said to turn off the Java garbage
collection using -XX:-UseGCOverheadLimit (
http://forums.java.net/jive/message.jspa?messageID=228596).
It seems like turning off the garbage collection would be the
opposite of what I am trying to do. Are there any thoughts about
this?
Are there any hotfixes for CF8? and where are they located?
Scott

Scott, the error is a symptom, not the cause of your
problems. Turning off that option won't "solve" the problem, which
is that you're running out of memory. More on that option in a
moment.
Let's talk first about your observation of trying to change
the max memory from 1 to 2 gig. Since you're on Windows (32 bit),
as you say, you can't use more than 2g per process (it's not really
a Java limit, but rather a Windows one).
But as you found, you can't set CF to 2g because the JVM
won't start. Again, this is not a CF-specific issue. You can see
discussions of the same problem with plain old Java apps, as at
http://forums.java.net/jive/message.jspa?messageID=228596.
So, similar to what they say, the consensus seems to be that
you can set it to somewhere between1.3 and 1.7 gb, before the JVM
won't start. You have to try different values for yourself.
Now, that extra few hundred meg may be all you need to get
past your problem, but really that's often just forestalling the
inevitable. You need to find why CF is using so much memory. You
say you're using CF8 but don't say if it's Enterprise or Standard.
If the former, then you have the CF8 Server Monitor (accessible in
the CF Admin, and discussed in a multipart series I wrote for the
Adobe Dev Center, as discussed at
http://carehart.org/blog/client/index.cfm/2008/7/30/45page_server_monitor_guide).
That, as well as tools like FusionReactor and SeeFusion, can help
you to better see how CF is using memory.
All three offer a graphical interface to show how memory use
is trending. You may see if it grows steadily throughout the day,
or grows in spikes. People tend to say "I have a memory leak", when
in fact it may be just that they have either a few requests that
use too much memory (so you'll see a stair stepping rise in memory
use concurrent with their execution), or it may be that they're
sticking stuff into shared scopes (session, application, or server)
and those are living well beyond the live of each request.
The CF8 Server Monitor even has a memory tracking feature,
but it has to be used carefully. If you enable it, you may find it
brings your server to its knees.I'll do a blog entry soon on how to
use it most effectively (something I learned since writing the
articles last year).
One thing that the monitor can tell you, without any of the
"start" buttons enabled at the top of the monitor, is how many
sessions you have. That may be very enlightening. You may have
thousands of them, and not realize it, because of bots, spiders,
and other crap requests. See the "active sessions" page of the
Server Monitor, and its graph icon in particular (discussed in more
detail in one of my articles).
Sadly, neither FusionReactor nor SeeFusion can tell you how
many sessions are currently running, so if you're on CF8 Standard
(or if others reading this are on 6 or 7, where they can use FR or
SF), you can't easily see how many sessions there are. (There are
undocumented, unsupported methods, such as discussed at
http://rewindlife.com/2003/09/08/undocumented-application-scope-functions/.
Just be aware some techniques work differently depending on whether
J2EE sessions are enabled in th CF admin.)
Finally, about your observation of the usegcoverheadlimit
option, and the recommendation to turn it off: the article you
point to doesn't say doing so would disable GC. I'm curious how you
may have concluded that.But digging into things more, I see that
disabling it (using the - before it) will turn off a feature
(introduced in 6) which limits the proportion of the VM's time that
is spent in GC before an OutOfMemory error is thrown. That's the
error you're seeing, that the JVM has detected too much time is
being spent in doing GC.
So turning off the option doesn't "turn off the Java garbage
collection". It just changes whether an OOM error will be thrown
even before being really out of memory, simply because too much
time is being spent in GC.
And even then, how this option works (if enabled, which it is
by default) changes depending on whether you're using a parrallel
or concurrent collector (as discussed in two places in
http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html,
if you search for that switch).
Hope some of that helps.

Processing data for a remote command failed with the following error message: Error occurred during the Kerberos reponse.

Hi!
We have 5 Exchange 2013 servers and when I’m trying to run a script that includes the cmd-let Get-MessageTrackinglog with StartDate = the first of the month and with EndDate = the end of the month I get the following error message after
a couple of hours. The script is run on the server SERVER01 and goes through the Message Tracking logs of all Exchange servers. I have tried the script on other servers and get the same result.

Hi Henado
Check the time on your Exchange server(s) relative to the DCs and ensure they are in correct sync
Use another account which is assigned the Organization Management permission and log to to the server run the command in shell and see the results
Run
Add-PSSnapin -Name Microsoft.Exchange.Management.PowerShell.E2010
Set-Adserversettings -ViewEntireForest $True and then run message tracking command and see the results
If none of the above helps you may need to remove and re-install the WinRM and see the results
Good Luck :)

I have two versions of Pr, one is the latest 2014 and when trying to open a Pr2014 session, I get an error message saying the project was saved in a newer version and cannot be opened. Help

I have two versions of Pr, one is the latest 2014 and when trying to open a Pr2014 session, I get an error message saying the project was saved in a newer version and cannot be opened. Could there be an issue with an older Pr application on the computer? Please help!

You need to be very careful which project you open in which version.
For 2014 make sure its on 2014.1 build 81.

I tried to install the latest version of iTunes on my Windows PC, but the installation failed and I have the error message "Runtime Error R6034 An application has made an attempt to load the C runtime library incorrectly."

I tried to install the latest version of iTunes on my Windows PC, but the installation failed and I have the error message "Runtime Error R6034 An application has made an attempt to load the C runtime library incorrectly." When I then tried to run iTunes (assuming that, since the new install failed, my older version was still OK) I got the message "iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 1114". I tried then uninstalling iTunes and reinstalling it fresh, but encountered the same problems. Help!

Java.lang.error message after updating blackberry protect

I took the update for Blackberry Protect today on my Blackberry Bold 9900 with OS 7.1.0.391 and now I get the java.lang.error message on re-boot. Anyone know what this is?
I've tried uninstalling BB Protect and still get it, also tried re-installing it and message is still there.
What is this error, how will it hinder-impact device and is there a way to fix it?
Thanks in advance.

Ok I figured this out
1) alt lglg - this will show the entire event log
2) click the blackberry key then select "options"
what we want to do is basically see what application or applications in the event log is causing the error,
In order to do that...
3) Click the blackberry key again... Select "hide all types"
Now we don't see anything in the event log, all the filters are unselected,
Scroll down in the list till you find the "java exception" filter, click it... You will see a small menu , select "toggle filter"
Now you will see exactly what application or applications is causing the java exception error :-)
Mine was facebook, it could be anything you never know,
Now.... Open up blackberry desktop , go to applications, remove the application or applications causing the error,
Select Update
Your device will now update then reboot, this might take over ten minutes, be patient
This will work :-)

Java.exe error message

I am getting a java.exe error message after installing Oracle 8i Enterprise Edition on a Windows XP home edition. Can anyone help?

Hi,
Oracle usually installs it's own JDK for it's usage. Probably the paths are updated so that iAS is not able to use java that is bundled along with it. Please check the version of java at the command prompt by issuing..."java -fullversion". Please let me know the outcome for me to help you further on this.

I had a itune update fail, now I get an error message (windows error 2). what do I need to do?

I had an itune update fail. now I get an error message. "windows error 2". I can not open itunes!

With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

When syncing with itunes, got error message saying had error and now ipad2 will not do anything other than showing the USB cable with arrow pointing to Itunes on screen. have done the reset and restart, but still get same thing.

when syncing with itunes, got error message saying had error and now ipad2 will not do anything other than showing the USB cable with arrow pointing to Itunes on screen. have done the reset and restart, but still get same thing. Ipad does not show up in itunes even though cable plugged in. Have shut down and restarted Windows 7 computer.

I had done all of that to no avail. I did call Apple Tech Support and after he suggested I try a USB port in the rear of the Win 7 computer, things starting working again. I had tried switching the USB port at the front of the machine but that had not helped. Everything is good to go again. thanks for your reply

Updated to Firefox 35.0 recently and I keep getting a Java Application error message everytime I pull up a new page

This is more of a heads-up rather than a ques
tion.
I recently update Firefox to version 35. My computer operating system is Windows 7 Starter. Since adding the update every page I pull up I get a Java script error message "Error: 'console' getter called on an object that does not implement window interface."
I followed the steps for trouble shooting extensions and managed to isolate the problem. It was an add-on extension for Youtube Auto HD 1.4. The message no longer pops up.
I hope others out there find this helpful.

Sorry didn't noticed it was solved.
