How to find the Kernel panic's cause?

I have a HP G7 server, OS is RHEL 6.0, and it often kernel panic.
Who can tell me how to find the cause?
I even try use kdump service to collect the cause, but you know, the kdump(kexec) have a bug, so collect fail.

pleese help

If you can't scroll to the bottomof the page:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Kernel Panic probably caused by Video Card: solutions?

Hi,
I have a G4 iBook, 12", 1.2 GB Ram, 1.2 Ghz, should be "Late 2004" Model.
This morning, while I was surfing, suddenly OS X crashed, just freezing everything on my screen (not the multi-language kernel panic screen), still on and working but no movement on the screen. Surprised, I hold down the power button and then again to start it again. Read the kernel panic (KP) log, send it to Apple and just after few minutes it does the same. The KP log is always the same, I use it for about a minute, then it happens again. Another reboot and then the iBook stops just before the login window. So, if I switch it on, it chimes, usual grey Apple logo, then the screen becomes blue as it always used to do before showing the login window but the it stops there.
If I boot with command-S, I obtain a working root command line, didn't check if it hangs in this way. If I boot in Safe Mode, it works, but it hangs there as well after few minutes. As you see in the KP Log, the cause is probably the ATI Graphic Card (even cnsidering that screen just freezes, as if the graphic card doesn't send nothing new to the screen), but I have no idea how I could solve this issue.
KP Log is the following:

Any ideas? Any help?

I believe you're right; your graphics card has some trouble. The iBooks are notorious for such things, unfortunately. I believe the heat of the machine causes the connections to loosen.
If you're in the US, you can send the logic board to Super Reball and have them fix up the connections; I believe the cost is around $75, if you remove the board yourself.

How to find the number of references created for a given object ??

How to find the number of references created for a given object in a big application environment.
That means, if i give any object name (of my application) as input, then how can i find the[b] number of references created for that particular object ??

Please do not post the same question multiple times.
As for your original question, there is no direct way to do it.
Especially not the way you phrased it,
since objects don't have "names".
Applications also don't have "names".
They have classes and instances.
Also, there are 2 related issues, and I'm not sure which one is the one you asked.
#1. Finding the number of references to the same object.
Eg.
Map<String,String> a = new HashMap<String,String>();
Map<String,String> b = new HashMap<String,String>();
Map<String,String> c = a;In this case, there are only 2 objects.
The first object has (at least) 2 references pointing to it.
The second object has (at least) 1 reference pointing to it.
(There may be more, if the HashMap library keeps
references to these things, or if the HashMap object has
some internal cyclic references...)
If you're asking this, then it can't be done.
It's an active research topic in universities
and software research labs, called "alias analysis".
Type it in google, and you'll see people are working hard
and having little success so far.
#2. Finding the number of instances created from a class.
In this case, what you have to do is to add a counter to
the constructor of the class. Every time an object is constructed,
you increment the counter. Like this:
   class MyClass
       public static int counter = 0;
       public MyClass( ) { counter++; }
    // Then later in your program, you can do this:
    MyClass a = new MyClass();
    MyClass b = new MyClass();
    System.out.println(MyClass.counter); // It should show 2Note: you won't be able to do this to every class in the system.
For every class you care about, you have to modify its constructor.
Also: when an object is deleted, you won't always know it
(and thus you won't always be able to decrement the counter).
Finalizers cannot always work (read Joshua Bloch's
"Effective Java" book if you don't believe me), but basically
(1) finalizers will not always be called, and
(2) finalizers can sometimes cause objects to not be deleted,
and thus the JVM will run out of memory and crash

How to find the user exit for order cancellation

I want to find the user exit for order cancellation. And also to ensure that no one amends the order once the canellation has taken place. The cancellation shall be deemed to be affected only if the vendor has confirmed the acknowledgement of the order cancellation.
I have got a Zreport where this order should not come as open order item.
Please tell me the method of finding the users exit for order cancellation and stop the order from getting modified. And also how to find the tables in which the data has to be updated that the order has to be cancelled.
In the PO header i want an additional tab <cancellation> by which the user by the help of userid and password should be able to cancel the order. An order once cancelled cannot be undone. A new order has to be placed. The new order can be placed refencing the cancelled purchased order.
My client has got a very stringent requirement. In the past cancelled order has been undone and caused lot of problems.
Regards.

hi
pls tell me t.code so that i will send all user exits related to that particular t.codes
Thanks & Regards

How to find the recent changes done in the workflow by user id ?

Hello all,
How to find the recent changes done in the workflow by user id ?
I have made changed in Production system .
Like changing the status ,
changing the agent ,
but for these it will , not ask for any request .
So i want to know is there any method to find what are the changes done by me ?
Thanks and regards

Hi,
This is caused by mandant settings in scc4. It's better not to make changes in PRD, because then your DEV en QA systems differ.

How to find the workflow for Change Request for the PO's

Hi All,
We have a PO which is pending and we can't receipt it again nor make payment on this. After checking the Approval history for that PO we found that the change request has been made. The change request was to change the amount to be paid to R39196 instead of R58237.00. We don't know where to check the workflow for the change request to identify the cause.
what i need to know is how to find the workflow for that change request? The other workflows can be checked using the po_header_id for the PO's but i am confused with the change request workflow
Your input will be highly appreciated.
Thanks in advance
Rgds,
Sonia

For 11.5.10.2 run this query to determine the keys to search on:
Select wf_item_type, wf_item_key from APPS.po_change_requests where document_type = 'PO' and Document_num = 'put-PO-number-here'
Then use the keys returned by the query to look up the Workflow in
Workflow Administrator Web Applications / Administrator Workflow / Status Monitor
Search using the results returned in fields "Type Internal Name" and "Item Key" in Status Monitor
The query for change requests on a specific Requisition would be:
Select wf_item_type, wf_item_key from APPS.po_change_requests where document_type = 'REQ' and Document_num = 'put-Req-number-here'

How to fix a kernel panic

my macbook pro is stuck on the kernel panic message, and i tried to restart a lot of times but it doesnt work my mac doesnt start, please can anyone help me?

Kernel Panics are caused by hardware problems or serious OS damage. The first thing I'd try is restarting while holding the shift key (this is a safe boot). If this succeeds at the very least you can now get important data from the hard drive onto an external drive if you haven't backed up recently. It is even possible that rebooting normally will now work (but I wouldn't hold my breath).
If safe boot fails or if the computer fails to restart after safe boot worked, the next thing to try is reinstalling the operating system. I hope you've backed up recently because I'd strongly recommend that you erase the hard drive and reinstall rather than just reinstall the OS. If you've been using TimeMachine use System Setup to migrate your data and applications and you should be good to go.
If your computer won't reboot with your install disk (or into recovery mode if you are using Lion) then you are probably looking at a hardware repair.

How to find the number of data items in a file written with ArryToFile function?

I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
If you are young work to Learn, not to earn.
Solved!
Go to Solution.

What about:
OpenFile ( your file );
cnt = 0;
while ((br = ReadLine ( ... )) != -2) {
if (br == -1) {
// I/O error: handle it!
break;
cnt++;
CloseFile ( ... );
There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
Proud to use LW/CVI from 3.1 on.

How to find the number of entries in a master data table

Hi Experts,
I am trying to find the entries in 0CUSTOMER master data.
BW>LISTCUBE>Data target: 0CUSTOMER and selected the fields that I need.
I would like to know how to find the "number of entrees". I tried to run the SUM for a count field, but it is taking forever as there are huge number of records .

Hi Dev,
Go to the change/display mode of the info object (0CUSTOMER) in your case. Go to the Master data/Text tab. Here you will find the master data tables according to your settings (P orQ or X or Y). Double click on the table name and it will take you to the SE11 display. From there, you can check the number of records as you do in any transparent table.
Hope this helps.
Thanks and Regards

How to find the number of links in a website

hi every body
can any one clear my doubt
my doubt is that
in a website how to find the number of links the hole website contains
is there any navigation tool to find that
plz help me yar
i am waiting for the reply

If you're talking about commercial sites (sites you don't have the source code for) I'm not sure.
If you want to count the links in site that you have the source code for, it should be relatively easy to write a Java application to do it. All you really need to do is have a list of the files you want to count links in, read each file line by line and check for the existance of the <a> tag in each line. Anywhere their is an <a> tag there is a link.
Hope this helps.

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

How to find the number of fetched lines from select statement

Hi Experts,
Can you tell me how to find the number of fetched lines from select statements..
and one more thing is can you tell me how to check the written select statement or written statement is correct or not????
Thanks in advance
santosh

Hi,
Look for the system field SY_TABIX. That will contain the number of records which have been put into an internal table through a select statement.
For ex:
data: itab type mara occurs 0 with header line.
Select * from mara into table itab.
Write: Sy-tabix.
This will give you the number of entries that has been selected.
I am not sure what you mean by the second question. If you can let me know what you need then we might have a solution.
Hope this helps,
Sudhi
