What is "gc cr disk read" event?

hi,
Do you know what "gc cr disk read" event exactly means? I could not find any useful information on oracle documentation, metalink and web?
I suspect that it is related to parallel disk reads on RAC nodes. I mean for a query assume that all rac nodes do db file scattered/sequencial reads in parallel. If main node where sql run has finished db file scattered/sequencial reads but other node(s) has not finished yet, then "gc cr disk read" event occurs on main node.
However, i could not find any information to prove or disprove this assumption

By the way there is an explanation here
Re: What means "gc cr disk read" event?
but Jonathan may not be right, because i see this event in my rac cluster which is a 2-node RAC cluster...

What means "gc cr disk read" event?

Hi everybody,
I have a process that executes four times per day, and in a specific execution the process consome most time. The quantites of data to be process in each moment is same.
Last day, I enabled trace to comper and I get the event gc cr disk read very difente from other execution.
Some one can explain what means the gc cr disk read event?
I have looking on the net but i found no documentation about it?
Thanks

Having done a search for exactly "gc cr disk read" on Google I can confirm that the available information on that particular wait is hard to find - but we can guess that it's cluster related (gc = global cache), for a consistent read (cr) and involves a disk read.
Possibly it's an indication that one node has requested a CR block from another node and been told that the holding node has been told to write the CURRENT block to disk (fusion write) and the calling node will have to read the current block and sort our read consistency for itself.
This would tend to suggest that you have more than two nodes in your cluster, and you have some blocks which (on occasion) are rapidly updated from all three nodes at more or less the same time.

GC CR disk read

Hi,
We are facing the gc cr disk read wait event especially when issuing the following sql statement.
select b.tablespace_name||':'||nvl(round(sum(bytes)/1024/1024),0) from dba_free_space a,dba_tablespaces b where a.tablespace_name(+)=b.tablespace_name and b.status != 'READ ONLY' group by b.tablespace_name;
This wait event occurs only when the block requested by the 1st instance is on the other instance and it is dirty so the second instance has to create a duplicate block for read consistency purposes. and more interestingly this wait event occured on 1st instance and the backups were running on the second node.
Does this mean that the tables related to the view dba_tablespaces and dbA_free_space updated during the backups or we might be hitting a bug.
Thanks,

"disk read error occurred" when i turned on my notebook. what can i do to correct this?

when i tried to turn on my computer, i got an error message stating that a "disk read error occurred"
turned it off, restarted, pressed escape & got HP advanced system diagnostics (version 3.1.1.0)
the hard drive test resulted in:
               smart check - passed
               short DST - failed
   failure ID: RLSNO3-5LC5T5-XD6V4J-60W303
   product ID: XZ165UA#ABA
notebook is pavillion - DV5 - 2231nr
windows 7 Home Prem OA
the notebook is about 6 months old, so it's still under waranty.
what can i do to fix this problem?

Hi,
Failure of the Short Disk Self Test would indicate that your Hard Drive is failing and will need to be replaced.
As your notebook is still under warranty, contact HP and arrange to have the drive replaced.
If you live in the US, contact HP Here.
If you are in another part of the world, start Here.

What do i do when my lap top says disk read error

when i start my lap top its go to a screen that says "a disk read error occurred" press ctrl+alt+del to restart

Hi,
Shut down the notebook. Tap away at the esc key as you start the notebook to enter the Start-up Menu. Select the Bios option ( usually f10 ) and under the Advanced or Diagnostic tab you should find the facility to run a test on the Hard Drive. Post back with the details of any error messages.

"Disk read error occurred" cannot even load System Recovery

Hello,
yesterday I powered on my computer, and it was almost froze, with only the mouse moving and even the task manager not showing up when called.
I first tried to make it go in standby, as I thought it was some program which didnt start as planned. After I closed the screen , the screen went black, but the pc continued to run. I then pressed the power button, shutting the system the hard way.
After that, I powered back the pc, which now only showed "Disk read error occurred, press ctrl+alt+del to restart" and obviously this wasnt the solution. I tried resetting the BIOS, then running the diagnostics on f2: it ALWAYS passes the test the first time, then if i try to run the diagnostics again, it says "NOT INSTALLED". I tried running the system recovery on f11, but the same "disk read error" appears.
I-ve already confirmed the problem lies in the hard disk itself {hitachi 750gb}, having plugged it in another notebook with an hitachi hard disk and still showing the same problem, while the other hard disk booted just fine in my HP.
I tried with a win7 cd, both recovering and installing a new version, but they both kept frozen for about 1 hour and did nothing.
I then made a bootable USB with Trinity Recovery Kit and after a quick diagnostic, it said boot partition has "unclean" windows files and tried fixing the problem, without success. I-m now writing from a bootable USB linux distro, because i cannot find a bootable iso oh hitachi recovery program, what should I do?
Is it possible the hard disk failed so bad for an uncommon closure of the system? It looks to me like some data got corrupted.
Please help me, as I-m an academy student and I use the PC for almost everything.
Thank you.

However, it does not have a valid fake msdos partition table, as it should.
Perhaps it was corrupted -- possibly by a program that doesn't understand GPT
partition tables. Or perhaps you deleted the GPT table, and are now using an
msdos partition table. Is this a GPT partition table?

What does the recovery disk assistant store?

hello everyone, my questions:
1.what does the recovery disk assistant store?
2.is it necessary to use the recovery disk assistant often or is it enough to use once.
thanks
Fatih.

As it said in the link I posted:
has same capabilities as the built-in Lion Recovery: reinstall Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari. This drive can be used in the event you cannot start your computer with the built-in Recovery HD, or you have replaced the hard drive with a new one that does not have Mac OS X installed.
And here it is explained further:
http://support.apple.com/kb/HT4718
It stores some tools (Disk Utility) to repair your drive and lets you connect to the app store to re-download the OS or restore it from a Time Machine backup. That's it.
And it will re-install or restore your system (OS), it will not touch your files. However,
NOTE: before doing anything like that, it is wise to have a complete backup - things can happen.

What type of hard disk should I use if I want to use it on mac and windows?

Hey Forum,
I am using windows xp on my macbook (snow leopard). I came across some dealers who say that there are hard disks for mac only and for both mac and windows. So, I wanted to buy a hard disk so that I can use it both on mac and windows xp, so what type of hard disk should I use? Must I partition into 2?
or are there any harddisk in the market which is compatible for both mac and windows xp without screwing up the format(NTFS/Mac OS X Journaled)? Pls look into this matter and help me with it.
All of your replies and suggestions is much appreciated.
Thank you.
Ala.

Run, don't walk, from that dealer! and never look back
Once in a very long while Apple will have customized firmware on drives, and it is possible to find SCSI/SAS or drives that are destined to be used with high end storage controllers.
But that is the exception that makes the rule.
SATA is SATA. Though.... there are now SATA III drives that don't work in XP, or that need a jumper, and Seagate and some drives have managed to deliver firmware that has caused trouble... and Apple has had to issue firmware updates to help compatibility....

Yay...disk read error

I just started an entirely new PC, except for the hard drive (160 gb, maxtor), which still had my previous installment of windows XP. On boot-up, I get the 'Post' splash screen, followed by like 10 sec's of a prompt if I want to set up RAID, and then I get ... 'disk read error, press cntrl+alt+del to reset.' I rechecked all connections and another run-through with no success.
Then, I tried replacing the hard drive with an older one which had windows 98, where the system got the splash screen, the raid prompt, and then just sat at the windows 98 splash screen indefinitely.
Lastly, I put in the windows XP cd with the 160 gig hd and created a new partition on the c: drive. After partitioning and prompting to reset, it again just gets to the 'disk read error, press cntrl+alt+del to reset' message.
Any suggestions? Thanks in advance.

Hmm . dunno exactly. i think the best process is memory module.
test cables for ide by swaping them round with the ones that are optical
what rating is your psu and whats are the amp specs
Try formatting a complete drive with full ntfs format. if you current drive has a previous partuion on it then that could be corrupting it.
we know the bios posts and we know ide works to an extent or your optical drive would fail
it seems that when loading os the resources may be taking more power if a drive is not getting power then it will also result in this error

GT780 Disk Read Error, Boots fine after 15-45 minutes

Hi.
I've been having a problem with my laptop for the past few months now. When I start it up I end up getting a disk read error but after a short time it seems to boot up properly. I will have this problem for a couple days and then the problem disappears for about a month then reappears for couple days then disappears for the same amount time. I've sent it in once but the problem started again about 1 month after it was sent back. Does anybody have any idea what the problem could be?

G460 Disk Read Error

Can someone help me, i'm figuring out what caaused this problem and i have so many files in my computer. When i turn it on it doesn't go through the LENOVO screen, then after 2 or 3 minutes it displays Disk Read Error, please press ctrl + alt the delete. the Harddisk light doesn't light up. and it makes a horrible noise. the noise I hear is like a Hard Disk spinning without a disk.

it seems your harddisc is dead. ( or possible connector issue )
if you have external harddisc box, remove your hard and replace into it, test your harddisc.
if it works, backup your data, replace your harddisc into computer.
try to re-install operation system. if it doesn't work, call lenovo and ship your computer back to service.

A Disk read error has occurred

My laptop froze the other day and now when I try to boot I keep getting the message A disk read error occurred. Any ideas of what I can do to get my computer to boot?

Which computer? There is a label on the bottom.

What caused the Windows 2008R2 Security event discarded

Dear Support team,
I have a windows 2008 R2 server, The security events didn't recorded from last year.
1. The maximum log size set to 100 MB, But the log file is 300 MB. The retention was set to "archive the log when full,do not overwrite events".
2. Below last entry security log show the registry key that i modified at that time. After i modify the registry value all of the security event were discarded
A registry value was modified.
Subject:
Security ID: domain\userid
Account Name: userid
Account Domain: domain
Logon ID: 0x2c202074
Object:
Object Name: \REGISTRY\MACHINE\SYSTEM\ControlSet001\services\eventlog\Security
Object Value Name: Retention
Handle ID: 0x100
Operation Type: Existing registry value modified
Process Information:
Process ID: 0x129c
Process Name: C:\Windows\regedit.exe
Change Information:
Old Value Type: REG_DWORD
Old Value: 0
New Value Type: REG_DWORD
New Value: 4294967295
3. As i know,The Windows Event Log supersedes the Event Logging API beginning with the Windows Vista operating system. Here is the KB link: http://msdn.microsoft.com/en-us/library/windows/desktop/aa385780(v=vs.85).aspx?ppud=4
And the registry key which i modified at the before ( \REGISTRY\MACHINE\SYSTEM\ControlSet001\services\eventlog\Security\retention ) Seems only apply to Event logging for Windows 2003 and prior system.
Here is the KB link: http://msdn.microsoft.com/en-us/library/windows/desktop/aa363648(v=vs.85).aspx
May i know what is the reason cause security event discarded ?
Does the retention setting at Registry still working at windows 2008?
Thanks very mush.
Randy

The new methods are via GPO described here.

FAQ: Installing Elements 10, or What do all these disks do?

When you purchase Photoshop and/or Premiere Elements 10 as a boxed product, you get a fair number of disks. The main reason for this is that a boxed product purchase of Elements is dual platform, that is, it's for both Windows and Macintosh.
When dealing with a Photoshop and Premiere Elements combo purchase, you get 5 disks. Here is what they all do:
Disk 1 = Installs the 32-bit version of Premiere Elements 10 and Photoshop Elements 10 on Windows
Disk 2 = Windows 7 64-bit installer (skip Disk 1 if this is your OS). Installs the 64-bit version of Premiere Elements 10 and Photoshop Elements 10 (32-bit)
Disk 3 = Installs Premiere Elements 10 and Photoshop Elements 10 on Mac
Disk 4 = Installs Premiere Elemenst Content (DVD themes, menus, titles, etc.) for Windows
Disk 5 = Installs Premiere Elemenst Content (DVD themes, menus, titles, etc.) for Mac
When working with Photoshop Elements only, you have 3 disks. Here is what they do:
Disk 1 = Installs the 32-bit version of Photoshop Elements 10 on Windows. Also includes a trial installer for Premiere Elements 10
Disk 2 = Installs a trial 64-bit version of Premiere Elements 10 for 64-bit versions of Windows 7
Disk 3 = Installs Photoshop Elements 10 on Mac. Also includes a trial installer for Premiere Elements 10
And finally, when using Premiere Elements only, you have 5 disks. Here is what they do:
Disk 1 = Installs the 32-bit version of Premiere Elements 10 on Windows. Also includes a trial installer for Photoshop Elements 10
Disk 2 = Installs the 64-bit version of Premiere Elements 10 for 64-bit versions of Windows 7
Disk 3 = Installs Premiere Elements 10 on Mac. Also includes a trial installer for Photoshop Elements 10
Disk 4 = Installs Premiere Elemenst Content (DVD themes, menus, titles, etc.) for Windows
Disk 5 = Installs Premiere Elemenst Content (DVD themes, menus, titles, etc.) for Mac

Is it rolling back the installation? you can follow the solution on this link:http://kb2.adobe.com/cps/894/cpsid_89403.html
try to save the file on your C drive if it doesnt work install it as trial first and just put your serial number once you launch it.
Hope this helps!
