thank you for so quick response.
I don't understand what happened when the error appeared.
The trace file is so difficult to read, I don't know what it want to show.
Would you like to tell me what happened with simple language?

OC4J Instance crashes on Linux

We have a standalone OC4J instance version 10.1.3.2 on Linux that we use to provide pdf print service for applications developed using APEX. Java version is 1.4.2. I have deployed the fop ear file to the instance, this is delivered with APEX. On several occasions, end users have reported that they can not open the pdf report. When I check the server, the OC4J instance is not running. There is nothing in the java logs or OC4J instance logs to indicate why the instance crashed. When I restart the OC4J instance, printing once again works. Has anyone else had stability problems with this product?
Thanks,
Don Morse

Standalone OC4J runs quite stable on every platform.
You should check the log files or the standard output (where you started OC4J). Also check the memory settings for the JDK. A common problem is that the JDK throws an OutOfMemoryException and won't respond anymore. You should also consider using JDK 1.5.0_x since it has a better memory management.
If this doesn't help post the complete command line.

Oracle instance crashed

Oracle-Version: 9i R2 9.2.0.1.0.
Hello !
My oracle instance crashed and I found the following message in the log file :
LGWR: terminating instance due to error 472
Instance terminated by LGWR, pid = 1304
I have not found any other messages and the ORA-00472 message says that the PMON process terminated with error.
Did anybody have the same error ?
I need to know why the instance crashed.
I hope you can help me. Thanks in advance.
Andreas

The 472 is just the error issued when the Oracle background processes are signaled to terminate. It would appear log writer took an error and either notified the other background processes to terminate or it terminated and another backgroun process detected the problem, probably smon, and killed the rest of the system processes.
Look in the bdump directory for the log writer trace file and see what it says. There may also be some entries in the alert log depending on exactly what happened.
If the database fired back up without problem and the problem does not reoccur frequently then if might just be one of those things. However, if you can find the trace file and error messages for the problem cause then you should probably open an iTAR with Oracle support to find out he fix/work around.

Why premiere CS% crashes opening project and in encore

I have 12gb ram- CPU-I-7, NVIDIA 5000 plus graphics card, asus 58P motherboard.
I have a 2 hour project on my time line. When I open the project, the system crashes and about 5 minutes later works fine. I now want to export the timeline to Encore to make a dvd menu. Encore imports(dynamic Link) the sequence and at the 50% mark, crashes.but does not want to open. I have no idea why systems are crashing. I have not rendered the sequence in premiere pro as I don't know if I need to when going to encore. Comments would be appreciated.
Leo.

The symptoms you decribe, white screen, the beachball, the not-responding message and the media pending message all are indicative of a Windows problem. Probably you will encounter the same problem when for instance you have 5 large (2+ MB) .HTML files open in Dreamweaver and those files have been modified enternally and need to be reloaded, especially in split mode.
It boils down to the fact that when opening your project, PR needs to get all those files from disk, or at least the indexed and conformed files into memory, as well as the .PEK files and while it is waiting for that to happen, it shows the media pending message. Windows itself is usually in a hurry to show the not-responding message, while it is waiting to finish a requested task, even when it is responding, albeit slowly.
My guess is that you haven't tuned your system yet, see Adobe Forums: Guide for installing and tuning a Vista... which also applies to Win7 and your disk setup may be lacking the necessary speed. After following the tuning steps, you can try to delete the media cache and then reopen your project. It will index and conform your clips again, so be a little bit patient for that process to finish.
Also have a look here: Adobe Forums: Generic Guideline for Disk Setup

Firefox crashed down many times (6-7) and doesn't open anymore giving me a warning sound each time i try to open it any suggestions?

I'm using firefox (now 27b2) having many tabs opened and i got used to the fact that many times crashes down ... each time i restore the session and it starts again ... but yesterday it "died" on me. Each time i'm trying to run it i get a warning sound and firefox refuses to open. As far as i remember i didn't install any soft lately ... but right before it's death, my pc was getting frozen and need it reboot ... that happened 3-4 times and then firefox "left" this cruel world. I run S&D, Malware bytes, Avast IS ... found nothing. Tried to open it in safe mode unsuccesfuly getting the same warning sound. I decided to uninstall it (Revo uninstaller) and used Ccleaner to wipe the leftovers then i tried to reinstall it but when running setup i get a message says "File corrupt" and everything ends here. I tried firefox 26 stab and it worked like a charm but the question remains the same why the beta version refuses to run and/or to be reinstalled ... If there is someone out there (I'm sure there are many...) with any suggestions or advices i would be very grateful ...Thank you all...

Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!
Thank you.

<b>WARNING:</b> Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These cannot be recovered unless they have been backed up to an external device!</u>

HT1665 There is a bug in the spellchecking functionality when typing in the web view or while using Blogsy App. Why? Why my IPad crashes so often?

There is a bug in the spellchecking functionality when typing in the web view or while using Blogsy App. Why? Why my IPad crashes so often?

I have always found spell check to be "buggy" in every version of all of the iOS's that I have run on my original model iPad and my new iPad - especially when replying and typing posts in these forums. It works perfectly in every other application on my iPad but it has never worked perfectly in any web browser that I have used on my iPad - no matter what I have done to try to correct it. That is what MY experience has been with spell check on my iPads.
As for the crashes on your iPad try these basic troubleshooting steps.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Quit all apps and restart. Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
/System/Library/LaunchDaemons
/Library/LaunchDaemons
Open Console in Applications>Utilities, check the system log for the date/time of the last problem & next startup for clues.

Oracle instance often down!!!

Hi
I've have an Oracle 10g (10.2.0.4) 64bits database installed on a x64 window server. The server itself has 16gb ram. My current SGA + PGA is about 4-5gb memory, processes=500 but I am still getting random problem like oracle instance killed/down, low swap page memory from OS, listener could not hand off client connection etc. Should it be the existing server RAM(10-11gb RAM free after deduct from the SGA+PGA allocated) is more than enough?

FireFox88 wrote:
So far from what I can recall my database server used to once a while getting "Significant virtual memory paging was detected on the host operating system" until i turn the OS page memory to system manage which is to use whatever hard disk space available, only then the warning seldom/rarely occur. listener could not hand off client connection is another error quite often prompt. When ever this error prompt, most of the time I've to bounce the database instance.Speculation - could be caused by PGA, as a result of poorly written PL/SQL code using very large PL/SQL arrays (for bulk collection). I have seen a single PGA (private process memory of a dedicated server process) growing to 50% the RAM size of the server. I have even seen a couple of server crashes due to the kernel being starved of CPU time due to swap space thrashing.
Before resetting a server in such a situation - get whatever diagnostics available. The problem will be gone (for the time being) after reboot, without the ability to get an actual look at just what the heck is going on. There are some magic sysrequest keys on Linux that is useful - all you need is the ability to echo specific keys to a proc device in order talk to the kernel and request various data and process dumps. Pity you are using Windows - not the easiest of kernels to troubleshoot.

Accidently remove oracle_home software, instance is down, how to do?

Hi,
I have a quick question,
when using installer uninstall(remove) oracle software, selected wrong oracle home, then
removing process only happens for 1 sencond (stop almost immediately), the instance still crashed down. how to bring up the instance, reinstall oracle?
or any other better way?
Thanks
Jerry

If this is a non-Windows OS, you only have to restore a backup of the ORACLE_HOME location.
If any parameter files (eg initSID.ora, spfileSID.ora, listener.ora, tnsnames.ora) were updated since the backup, you'd have to correct them.

Anyone have a solution to why Illustrator CC crashes on Mac Pro running OS 10.6.8?

Anyone have a solution to why Illustrator CC crashes on Mac Pro running OS 10.6.8?

We recently (yesterday) upgraded our Adobe apps to CC versions. InDesign, Photoshop and Bridge all run perfectly. Illustrator crashes at startup. Tried launching it from Administrator account and it crashes. I have disabled fonts except the bare minimum, no success. If it would launch, then I might be able to narrow it down to an incompatible print driver, but it has to actually be running first. We use no third party plugins with it, so I doubt that is the issue.

Why does Safari crash in the middle of a movie or show from the internet?

Why does Safari crashes in the middle of a movie or show from the internet?

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if Safari crashed, you would enter "Safari" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

Can anyone answer why photoshop CS3 shuts down when I use the scanner?

Can anyone help me with why photoshop CS3 shuts down when I use the scanner? I recently upgraded to OS X Yosemite.

Ask in the PS forum and be much more specific. You have not provided exact system information, crash logs, scanner details. That said, this may be a compatibility issue that can't be overcome.

ASM instance getting down

While production database is operational, ASM instance gets down out of sudden.
The error reflecting in alert log is :
ORA-15064: communication failure with ASM instance
ORA-03113: end-of-file on communication channel
Also in trace files the same error is reflecting. I am unable to find the root cause why the ASM instance getting down again n again .
Kindly help !
Thanks !!

I thought about more input. But well: Check for errors in the clusterware logs next. And check your system logs.
Any tracefiles created by the ASM instance?
A note: You´re on 10.2.0.2.0. Thats way too old. The current version is 10.2.0.4.0. I STRONGLY recommend to upgrade your clusterware and ASM to that version. If you need for some reason you can leave your database on 10.2.0.2.0.
