Frequent Locking

Hi all,
We were developing a system based on Oracle8i. Then we upgraded to Oracle9i, which provided nice performance enhancements. On the other hand, we keep facing a problem.
The schema which contains the application we're developing keeps locking some objects. We've seen the error "RA-04021: timeout occurred while waiting to lock object" about 100 times now!
This error raised in many cases: DML statement, complie a procedure and even sometimes when querying a table.
Even killing the suspicious sessions using ALTER SYSTEM KILL SESSION statement didn't manage to solve the issue.
We hadn't faced this problem in 8i. :-S
Any clue plzzzz???
Issue Info.
Client OS: Win2000 SP4

I am getting frequent lock-ups and blue screens during boot up. The lock ups occur during normal use and I cannot click anything or force quit. The cursor shows something is loading, but never stops. I have to use power button. Ideas?

My iPad frequently locks up, even after updating to iOS 7.1. When it locks up it's nonresponsive to the home button and the only remedy is to force a shut down and reboot. Help!

DEVICE NOT RECOGNISED IN ITUNES
If you have connected your device to your computer and it does not appear in the side bar in iTunes then for Windows computers read http://support.apple.com/kb/TS1538 or if you have a MAC then read http://support.apple.com/kb/ts1591 for troubleshooting steps.

Table Row Frequent Lock

Dear All,
Recently we had changed our remote connection from 128KB Leased Line to high speed IP VPN (1MB) MPLS based lines. After that onwards Oracle table rows are getting locked frequently. We are using Windows 2003 Server Std with 9i 2.0.7 database loaded. Server Total Memory is 4GB with 3.2 MHz dual processor.
When we increase the sga_max_size (1400MB or above), ORA-12500:TNS:Listener failed...... error appears and users can't connect to our database server.
Memory Configuration is:-
Shared Pool - 352MB
Buffer Cache - 584MB
Large Pool - 128MB
Java Pool - 16MB
SGA Max Size - 1281.573 MB
Aggregate PGA Target - 259MB
Please help to correctly calculate the Memory configuration if its wrong. Or is there any other solution to sort out the table row locking problem.
Thanking you all in advance,
Manesh

On initial guess, it sounds like you are chasing the wrong aspect of the problem.
You do not describe what the application is doing, but logically it appears that you are getting more transactions happening because of the higher access speed. In other words, the client is no longer being throttled back.
You also do not decribe the actual kind of lock. It intrigues me that specific rows would need to be locked - that implies that the application is attempting to capture the rows ahead of time. This sort-of feels like the application may have been ported from another system, or designed based on a totally different locking machanism that what Oracle usess, forcing Oracle to try to work in a way it is not supposed to work.
Simply throwing more resources at the problem will [probably] not solve the problem - it may alleviate it for a while. Better would be to understand what is actually happening and correct the root cause.
I encourage you to read Tom Kyte's "Expert Oracle Database Architecture: 9i and 10g Programming Techniques and Solutions" to get some tools to help undertsnad and isolate the actual problem. (http://apress.com/book/bookDisplay.html?bID=10008)
As for the ORA-12500, I believe Metalink has a few notes about that.

Firfox frequently locks up when accessing American Express Web site

Firefox will frequently (but not always) lock up (i.e., I must use the Task Manager to terminate the process) when initially accessing the American Express web site; or when clicking on the "recent activity" link; or when clicking the "Log Out" link. I click on the red "X" to close the window, the window is removed from the desktop, but the process "firefox.exe*32" is still running preventing it from restarting - message box: Can't open Firefox since it is still running (paraphrased text). This is a recent development since Firefox 5 - worked fine for years prior.

I located some suggestions for flushing the cache.
There are really three ways you can flush the DNS cache on your iPad.
1) Simply turn the iPad off and on again using the power button. A simple reboot will go a long way.
2) Turning on Airplane mode and then turning it off again will also clear the DNS cache and should be enough to fix the problem. Tap on your Settings icon, then swipe Airplane mode to On and then back off. Since Airplane mode disables the wireless features of your iPhone, iPad, or iPod touch to comply with airline regulations, this will generally do the trick.
The third method would reset all your network settings and I'm pretty sure you don't want to do that right now.

Frequent lock ups

I am almost at my wits end with my MAC. When it is running right, it is wonderful. When it's not, its very frustrating. Shortly I will be contacting Apple AGAIN to try and resolve the problem. this has been going on for about 5 months, and it is always the same problem, requiring the same resolution to get it working.
The problem is that the machine locks up, and I can't do anything with it, other than turn it off with the power button, wait a while, restart it, use Drive Genius 3 to repair it, restart again, and it works fine, for a few days.
After locking up, shutting it down and re-starting, the same error code appears "Invalid Volume Directory Count". This has happened 13 times since August 29, 2010.
I have spent many hours with MAC tech support on this issue the first time. Worked for a couple of weeks.
Second time I was instructed to bring it into the "Genius Bar" where they installed a new hard drive. Worked for about a week.
Third time I re-installed the operating system. Worked for about a week.
I have been working with this issue because I rely on my MAC for so much, but on several occasions I have lost data when the computer stopped working.
I am entering this information on this forum in the hope that somebody else has had this problem, as well as a fix for it.
Thank you for your help.

Hi-
Your error could come from a number of places, with RAM being a likely source.
Replacement of the hard drive helps exclude that as a possible suspect (for now).

Wierd lines on my display and frequent lock-ups w/ and w/o display problems

When booting I sometimes get weird lines and blocks on my display (the GRAY Apple screen) and then it hangs, other times the computer will boot and run fine for 20-30 minutes and then the display goes wonkers with blocks and lines and the computer does not respond. The only way I can get it to boot is to reset the PRAM by letting it CHIME 3x and then occasionally it will boot without issue and run, while other times I still get the blocks and lines on the display.
When I am able to get it to recover and re-boot after the lock-up and display problems and occasionally the box in the middle asking me to re-boot similar to a kernel panic the OPS gives me the option to REPORT the error and here is the error for others who would know more...
Thank you in advance,
Darren

Anyone know what is causing my problems? I thought it was heat so I downloaded a CPU and FAN temperature monitor and the CPU was getting VERY HOT at first so I then ramped-up the CPU FAN SPEED to maximum - it turns out the CPU FAN was not rotating well at low speed - since then I have cleaned and checked the fans and they all work as they should and blow on high(er) when the CPU temperature is above a certain level.

S.U.
Is there a kb article or something that would illuminate what to look for in these logs, or is it a matter of learning by osmosis?
Both. I am not skilled in reading logs. It is a very technical and time consuming task for the uninitiated (me!) In scanning a log I look for the backtrace and loading dependencies. The first item in the backtrace is usually the roadblock.
Beyond that you can look at the Technical Note TN2063: Understanding and Debugging Kernel Panics
Should make for good bedtime reading. Puts you right to sleep.

Itunes slow to load and frequently locks computer

why is itunes so slow to load and why does it lock up so much?

I was able to get my iTunes functional again after disabling a lot of my windows services -- use this thread for your reference:
http://support.apple.com/kb/HT2292?viewlocale=en_US
I haven't pinpointed exactly which service(s) were causing the iTunes slowdown, as I haven't had time to test re-enabling all of them yet. But so far I've just disabled the services that I know I don't need anymore and iTunes has been running like a champ =)

ITunes 9 and Windows 7: iTunes frequently locks up

Hi,
I just wanted to report that my iTunes frequently will freeze up when not playing. For example it could not be playing a certain song, and I press play, and the play button just freezes at the pushed in state. The only way I've solved this is by rebooting because just ending the process doesn't solve the problem.

7.3.2 is the last version of iTunes that was designed to work with Windows 2000. Nothing later than that supports 2000: iTunes 7.3.2 for Windows 2000
iTunes 9 requires:
Windows XP Service Pack 2 or later, 32-bit editions of Windows Vista, or 32-bit editions of Windows 7. 64-bit editions of Windows Vista or Windows 7 require the iTunes 9.0.2 64-bit installer

Frequent lock-up of iTunes Store feed

We got our ATV a couple of weeks ago. Everything was fine at first. Watched a couple of movies on our Netflix Instant View without a hitch. But a week ago I was watching a flick and the picture froze as though I'd paused it. I messed around with the hand control--which didn't seem to do anything--and it finally restarted in a minute or two. Then it happened again. And again. But this really started happeneing since we've been renting TV shows from iTunes. It would freeze, the timeline indicator would appear with the little endlessly spinning wheel indicating it was waiting for signal to download or something. I messed again with the hand control and a dialog would appear saying stuff like "Loading..." or "Ready to Play in 18 minutes (or 25 minutes, or 1 hour and 15 minutes)" and we'd have to sit there and wait for it to decide to say "Your TV show is available. Press Play to begin." If we hit fast forward before it was ready (trying to goose the thing) it would lock up and start the process all over again.It was getting to the point where an 42-minute program would take an hour's time to watch.
I tried changing cables and went back to a rented show where it had happened and it worked fine. I then changed back to the original cable and it too worked fine. However it was earlier in the day and it got me to wondering if it's a server streaming issue. Could this be it? I'm at a loss. It's making me question the worth of this paradigm.

I think that it might be caused by some problems in your feed. You have a lot of HTML in your podcast description and subtitle areas that could possibly be causing iTunes to have problems reading it properly.
I ran the feed through feedvalidator.org and it popped up several problems. One of your <itunes:subtitle> tags is too long. The <itunes:subtitle> should just be a short one line description of the podcast episode. Feedvalidator is saying that one of these is over 255 characters in length.

like spread spectrum,eist etc and since i came to know from other threads about the video corruption issue,i updated the bios to 1.2B1 still the problem persists.the system is completely unpredictable as it simply locksup with the audio goin into an infinite loop with the video still.I hav everything running at stock speeds includin CPU,NB,DRAM all set to auto.
My memory timings are 5-5-5-18 with command rate 2T at 1.8V.CPU,system and GPU temperatures are normal.Please help me as i am not able to hav a stable system.Suggest any remedies for this issue.
thanks

ok i will up the CPU and NB voltages as u specified and lets hope its the end of this problem and i hav disabled the spread spectrum in the bios before only..

Ms 6378 ver 3.0 or what / lock up Athlon XP 1800

:O
I too have a MS-6378 notherboard. Version 3.0. I am running a Athlon 1800 XP with 256 MB ram. I have a problem that my computer lockup everyonce in a while. Sometimes I could be surfing the net or the next just typing a letter on word. I know I can not play any games because that is a automatic lock up. I tried to uninstall the on board graphics and install my Nvida TNT 64 Pro. No way computer lock up on boot up. For those of you thast are having video problems, can you see the first screen at all. If you can make sure you go in to your bios and change the video to AGP. Yes I know that you don't have a AGP slot but MSI considers that on board video junk a AGP graphics card, I guess. Any way MSI says on their page realease for the ms-6378 that only Version 2.1 supports Athlon 1800 XP cpu's. My book says the one I have does. What gives?????? I amn tired of frequent lock ups. I has nothing to do with heat. It can lock on boot up or sometimes after 12 hours of sitting here. SOme please help me. If anyone needs help let me know. May I hqave been through that as well and can help.

Hey buddy, I have a similiar problem with my computer. What happens is that my CPU overheats extremely bad and locks up. I don't know what's happening. My computer is a MSI board, not sure which since I sold it already with a T-Bird 800. It say in the bios that the heat is as high as 55 C or 110 F. I been using my system for 2 years now (sometimes I leave it on 24/7), and it just suddenly happened one day. I know it doesn't have anything to do with my CPU or FAN, cause I replaced both of those (I also use termal grease). I was using Windows XP, than I switched back to Windows 98 SE, same thing happen. Sometimes I just want to boot up and it will lock up. I would format and it would lock up half way too. If anyone knows whats happened to my computer, please let me know! Thanks.

Aperture 3.1 - Love Full Screen Mode, Hate The System Lock-Ups

Hi Guys,
I don't know if I'm the only person encountering this issue but Aperture 3 is driving me nuts. While I absolutely love the program and the full-screen mode, what I hate is the frequent lock-ups that force me to completely restart my iMac. Having the application lock-up is highly annoying but at least in "normal" mode I could kill the application from the Dock or Activity Monitor. However, when I'm operating in full-screen mode then I can't switch out of the application and seem to have no option but to completely restart my computer. This problem, which I first started experiencing with version 3.0 but which does seem to have been addressed in version 3.1, is happening so often that I'm afraid now to even use full-screen mode.
This problem only, to my memory, seems to happen when making adjustments but it does not seem to matter which adjustment. In the most recent occurrence the lock-up happened when I cancelled the application of a Crop by clicking the X icon on the Crop HUD.
Does anyone know either a) what might be causing the lock-ups, or b) how I can kill Aperture without having to completely restart my computer?

You could also set up SPACES to see if that works when lock up occurs in full screen
Apple Icon > System Preference > Desktop & Screen Saver > Hot corners
I have bottom left set to spaces
Then drop the mouse to bottom left, 4 windows appear, drag aperture to a seperate window and run there, you desktop is in a different space and can be accessed by bottom left of screen mouse movement (if the mouse works when A3 locks up)

IPhoto 8.1.2 - on a teacher's iBook: Worked flawlessly 2 weeks ago. Now it continues to lock up, it often will not import scans, I can not rotate a picture - it just flips back and forth. HELP I need to get a project out!

I created a beautiful Keepsake book a week or so ago. It worked flawlessly. Since - I've had several problems (nothing has changed on the computer/system). iPhoto will frequently lock up causing me to force quit. Other times, upon opening, it says that I don't have permission or something to open it. It often is not importing a scan saying it is an unrecognizable format (it's what I used before). When trying to rotate a photo it keeps flipping back and forth and wont stay put.
iPhoto 8.1.2
I've run Disk Utilities multiple times - fixes for about 1-2 scans/launches of iPhoto
I've restarted the computer.
I've tried to update - but can't locate a version my computer will allow me to update to.
Using an HP C3180 scanner/printer --- that is also recently not working ---- locks up, takes FOREVER to scan and then show up on the desktop.
HELP ME!!!! We're trying to get 2 books out for our students before the end of the school year.
Thanks

Sounds like your Library is corrupted to me. Simple solution: restore form your back up.
Other than that:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

Pdf files are locking up mac repeatedly, having to reboot - Please Help

I've been using a website (not mine) where the user enters info into a form, and it generates a single page report that pops up a download dialogue box on your computer that says:
“bh_main-53.cfm” may be an application. It was downloaded from the Internet and will be opened by Adobe Reader. Are you sure you want to open it?"
Smaller text notes that firefox has already downloaded the file. When you say Open, it automatically launches Adobe Reader and displays the file. From that point it can be saved as a pdf. I've been using the macintosh Preview.app with the resulting documents also - Preview can open both pdf and cfm files. Oddly enough, Adobe Reader (AR) can't open cfm files, and yet it is automatically called and displays these files.
The problem is that it seems that working with these files either in AR or Preview frequently locks my entire computer up. Typically the screen just freezes, while the cursor can still be moved around. Sometimes I get the spinning wheel, but sometimes not. Computer won't take any input from cursor or keyboard, waiting doesn't help, and I wind up having to use power key to do a hard shutdown.
What is going wrong here, and how can I fix it?

Did you try this one
Apparently you need to tell Windows that you want to use the machine as a file server and that it should allocate resources accordingly. Set the following registry key to ‘1′:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
and set the following registry key to ‘3′:
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size
After making these changes and restarting, I haven’t seen this issue arise again
