WebServer needs restart if Oracle DB is down.

We are developing an Java Server Pages (JSP) Application. We are
using Oracle Thin driver for connecting to Oracle 7.3.3 Database
thru' JSP.
When there are people logged on to the JSP application and I
reboot the ORACLE DB Server, our JSP Engine hangs. Unless I
restart the web server (Microsoft IIS 4.0), JSP Engine does not
initialize and Application does not run at all.
Another observation is that if we don't use thin driver and use
OCI driver, restarting the WebServer is not required. When
Oracle Database is up, Web Application resumes to run smoothly.
(However considering Platform independance, usage of thin driver
is an essential requirement for us.)
Is there is any process which I can kill on the web server to
reinitialize JSP Engine ?
Thanks in Advance,
Vinay.

Thanks for your response Justin, I understand that Enterprise Manager does that, but wouldn't the EM be on the same server. As I explained, there are scenarios where my Server itself goes down. So writing another program on a different machine would be the only solution ? Kindly correct me and provide any alternatives if available ?As I said, Grid Control involves installing agents on the various machines you are monitoring and having Enterprise Manager running on a separate server. The central application pings the agents periodically-- if the agent doesn't respond because the server is down or if it does respond and indicate that the database, the listener, or some other component is down, Enterprise Manager knows that there is a problem and alerts you. Of course, Enterprise Manager can also send you alerts for hundreds of other problems.
As Sybrand points out, Enterprise Manager is hardly alone in having this sort of architecture where agents are deployed to the monitored machines and a central process collects the information from many agents in order to provide for centralized management.

Kernel Panic: You need to restart you computer. Hold down the Power button until it turns off, then press the Power button again.

I apologize for writing a book, but I think explaining the full story may possibly get me a correct answer. I hope that someone can give me some insight as to what is the problem with my MacBook Pro. I have a MacBook Pro (15-inch Early 2008), model identifier: MacBookPro4,1 running OSX Lion 10.7.5 with 6 GB memory. My wife first noticed a problem with the display. Every so often it would get fuzzy with jumping lines going across the screen making it vitually unviewable. The final time that incident took place the computer froze which required holding down the power button to restart the computer. The computer started up to the point of the Apple logo and the spinning gear for quite some time until the screen darkened from top to bottom displaying the following message in five different languages: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again." I have read other blogs and support communities where people get the message intermittently, but my computer would not go past that point no matter what. Through research and the Apple Store I was told that this is a Kernel Panic. The so called "Apple Genius" at the local Apple Store was unable to get the computer to boot past that point even with his gadget. It would not startup in recovery mode, safe mode or off of a disc. I forget exacty what he told me, but he said it was getting past the first two startup steps, but it would not get past the third step which is to mount the desktop. He guessed that it may be a problem with the hard drive; a loose wire or something or other. I disconnected the hard drive completely and took it out. Everything appered to be connected properly. Then I installed it back correctly, but it did not solve the issue. So I guess I disproved his theory of a loose wire... I purchased ProSoft Data Rescue 3 and connected my MacBook Pro to another Apple computer using a firewire 400 cable. I was able to get everything I needed off of the hard drive. I did some more research and I decided to restart the MacBook Pro in verbose mode (holding down the command button and V button). The computer magically started up!!! I was upset that I wasted my money on the ProSoft Data Rescue 3. I managed to take additional items off of the computer and back it up on to an external hard drive. After some time the computer froze. I repeated the power button process to restart and received the same kernel panic. I managed to get the computer to startup approximately six or seven more times via verbose mode; each time the computer staying on for a shorter amount of time before it would freeze. I managed to run Disk Utitlity. I performed first aid to fix the hard drive and it said that the hard drive appeared to be fine. After first aid I erased the hard drive and booted off of a Lion disc to perform a clean install or an erase and install. Lion installed until the progress bar got the the end where I received a message that there was an error installing Lion, please try again. Each time I attempted to install the software I would receive the same message. Eventually the computer would not boot from the Lion disc. I went back to the Apple Store and the Apple Genius was able to get the computer to boot off of his gadget where Lion istalled completely. I set up the computer as a new computer. He said that he partitioned the hard drive as DOS and then back to Mac OS Extended (Journaled) which would get rid of any errors the drive may have had. He guessed that the problem was the hard drive, but was not exactly sure. When I brought it home I installed all of the software applications I had on it previously. Approximately three days later, which may have been the fifth of sixth time starting up the computer, the display became fuzzy again and the computer froze. The computer did restart once and I was able to retreive a "log" which I have pasted below. After if froze for the second time it restarted once using verbose mode and froze almost immediately. After holding down the power key to shut it down and then restart; I received the same kernel panic after the Apple logo and spinning gear which put me right back to square one. Now the computer will not boot via any method. It freezes at the end of verbose mode which forces you to hold down the power button to shut down. I also read that poorly seated ram may cause this issue, but I removed and installed the ram multiple times. I even purchased new ram from Other World Computing (Mac Sales) 6 GB, but that did not make a difference. I think I may see six possible problems on the verbose screen mode, five errors and one warning; I will type them out here:
1. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key $Num (kSMCKeyNotFound)
2. SMC: :smcReadKeyAction ERROR: $Num kSMCKeyNotFound(0x84) fKeyHashTable=0x0
3. SMC: :smcInitHelper ERROR: MMIO regMap ==NULL - fall back to old SMC mode
4. WARNING - ACPI_SMCCtrlLoop: :initCPUCtrlLoop - no sub-config match for MacBookPro4,1 with 8 p-states, using default stepper instead
5. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key MOTP (kSMCKeyNotFound)
6. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key BEMB (kSMCKeyNotFound)
I was hoping that someone could read my log to ascertain wether or not they see a problem that stands out. I was also hoping that someone could tell me if verbose mode provides any information that may be wrong with my computer. I just hope that someone can give me some insight as to what may be wrong with my computer. If it is the hard drive I will easily replace it, but I want to make sure that is the problem first before I waste money on a hard drive or anything else. Please let me know if anyone requires any other information from me.
Thank you!

I had already written a book and I did not want to bombard people with more information, but in my previous research I did come across the major issues with the NVIDIA card. I also was well aware that Apple offered a replacement program that ended in December of 2012. I was going to add that in my original post, but I discounted that theory because I put my faith in the so called "Apple Genius" when I made my second trip to the Apple Store. I brought the NVIDIA card issue to his attention and asked him if he thought that may be the problem, but he said no. He said if it was the NVIDIA card that the screen would be completely black and there would be no startup chime. When I experienced the screen issues I thought it was a problem with the NVIDIA card or the logic board. I asked myself, how can a flawed hard drive cause the screen to act funny.
nbar and Rick Warren, I thank you both for your help and insight; people like you are the real "Apple Geniuses." I was hoping there was a way I could wipe the hard drive before I dumped the computer or attempted to sell it. I guess I will look into purchasing a new machine when I have the funds. Again...thank you both!

"You need to restart your computer. Hold down the power button for seve..."

Hello,
I have recently been getting this same message "You need to restart your computer. Hold down the power button for several seconds or press the Restart button." whenever I start up my computer. It happens about 95% of the time. I have been reading on different forums that I should reset the PRam and the NVRam and I have been doing so and it does help as it does EVENTUALLY start up (sometimes takes me 5-10 min. to get it to start up).
I have also read that it may be the RAM that is loose, so I did check that and made sure that the ram is properly placed (which it is).
I don't know what else I can do. Should I reformat and reinstall Mac OS X?
Here is the exact error form the dump:
IOAPIC: Version 0x20 Vectors 64:87
AppleACPIPlatformExpert::start failed
panic(cpu 0 caller 0x55c095): "Unable to find driver for this platform: \"Macbook 2,1\".\n"@/SourceCache/xnu/xnu-1504.9.26/iokit/Kernel/IOPlatformExpert.cpp:1389
Debugger called: <panic>

Well just got around to installing the new HDD and RAM yesterday, and I am sad to say... that the problem persists. :/
I reseated the memory and made sure they were in there properly, and I also installed the HDD and ran DiskUtility before I erased/reformatted and installed a fresh version of MacOSX Leopard, then updated to Snow Leopard.
As long as I am using my computer everything works fine, the problem occurs when the machine is shut off or put to sleep for a long period of time. Because when I shut it off and turn it right back on a few minutes later it works, or if I shut the lid and open it 10-20 min. later everything works fine, it's only when the machine is off or asleep for long periods of time.
So, I do not know what else can be wrong.
Should I try to take out the old RAM and just leave the new module in and see if that works out? See if that specific module is faulty?

On startup: "You need to restart your computer. Hold down ..."

When I start up from system folder 10.4.3 on hard disk, I get this message:
"You need to restart your computer. Hold down the Poweer button for several seconds or press the Restart button."
When I do this, my eMac restarts but returns to this very same message.
I did recently fix disk permissions using Hard Disk Utility. Tech Tools program reports no failures.
How can I restart my computer?

Find some body that can download and and burn you a copy of techtool 3.0.4 contact micromat and see if they know of a way to roll back a repair. Diskwarrior might help. There again check for the version number compatibility. Utilities are not like they use to be on OS9 and below; here you could use a version designed for lower OS and get by using it.
Todays utilities are based on the operating system themselves. There was a Major change in the version of UNIX used in OS X.3 and X.4 previously they used BSD (Berkley Systems Development) originated my Berkley University. Apple had to pay a Royalty payment for each copy sold. OSX uses FreeBSD UNIX which originally started from BSD UNIX; but, was taken over by the General UNIX community under a License like Mozilla uses for FIreFox and others. Anyway it can be used Royalty free. What's better is FreeBSD is constantly being improved literally daiyly; and therefore is much improved.
I digress. because of these differences the utilities must be written for the differences in code. And what worked on one doesn't on the other.

Problem restarting my Oracle WebLogic Server 10.3

I am having a problem restarting my Oracle WebLogic Server 10.3.
If I try to restart or republish my server, it gives me the error 'weblogic.management.ManagementException: Unable to obtain lock on D:\user_projects\userdomain\servers\AdminServer\tmp\AdminServer.lok. Server may already be running'.
This problem happens only when the server is inactive for a while. Say, if I leave the server running overnight without any activity, the server state reads stopped in the morning, even though background java processes are still running. Now, at this point, it doesn't let me restart or republish my server until I explicitly kill all the java process from windows task manager.
Any help to solve this highly frustrating problem is gratefully appreciated. BTW, this happens on development systems, running on windows, using Oracle Workshop for WebLogic v10.3.
There are 1 nested errors:

</jsp-param>
I saw this thread: Weblogic server 10.3 needs restart to reflect jsp changes. , but it not helping me.

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?

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.

If restoring the phone as new did not solve your problem, you'll need to bring the phone to Apple for evaluation.

Many Thanks,
Need a small clarification in the normal scenario it works, if shutdown the server without shutdown the database we not receiving the alert.
is there any way i can configure alert mail for the instance shutdown (database is up and oracle instance is down) due to some unexpected reason.
Thanks
sankar"database is up and oracle instance is down"
A very interesting concept. Given that a database is just the collection of files that are kept transactionally consistent, and the instance is the memory and processes that manage those files, could you explain what is meant by "database is up and oracle instance is down". If the instance is up it may (or may not, depending on its state) have the database (files) open. If the instance is not up, then the database is ???

As Meg said, no, you don't need a converter. Take a close look at the charger... it says 110-240VAC Input, or something similar.

Cannot restart - log out or shut down...VERY FRUSTRATING!!!!!!!!!!!!

Hi
I can't restart, log out or shut down my power book g4. I have always done it through the apple display cinema to which is connected but when I hit the side button on the apple display, nothing happens the light on the bottom-right corner dims but no window pops up with the usual shut down/sleep/log out options.
Even if I try directly from the menu...nothing works except the sleep option.
I tried as well directly from the power book after having it disconnected from the display, does not work.
Disk permissions are repaired, but it did not help.
PLEASE HELP HELP!
Many thanks in advance.

Hmm, sounds to me like a software issue. Maybe something is installed which prevents the shutdown. It could be harware (peripherals) too. Try without any connected peripheral (display, usb/firewire-devices, etc.). If that does not work try adding a new user account (you can call it "test") via System Preferences and see if the problem is the same with this user.
Good luck!

The remote app requires both to be on the same network and home sharing to be enabled, you will need the physical remote to set this up. You can purchase a replacement through Apple.
