Why can't I drop the ASM disks and stop ASMLib?
Hi, I wanted to remove the disc, but this operation has failed:1.
/etc/init.d/oracleasm deletedisk DATA1
Remove ASM disk "DATA1" [NOT]
I know there is the solution to replace header ASM on a disc information
DD if = / dev/zero of = < your_raw_device > bs = 1024 count = 100
and then droping is successful
but I've also seen resources who said that it should be count = 50
If someone could confirm count = 100 or 50?
2.
In addition to this I tried to stop ASMLib and she doesn't have too:
stop /etc/init.d/oracleasm
Drop Oracle ASMLib discs: [OK]
Close the driver Oracle ASMLib: [FAILURE]
OK, so using dd will help me to get rid of the disks, but I'm worried about ASMLib in general, why can't you stop it? All instances of the ASM have been removed before. There is no software installed ASM, in addition to ASMLib.
There are several things not clear
1 as most of the people here you forgot to display four-digit version number, assuming that Oracle never changes, or we can guess that you are running.
The two statements are false. To stop asmlib, you use exit oracleasm
2 you use the root account or another account? You must use the root account
3. Why do you not use the oracleasm command?

Why can I not move the photos in an album
I've updated to 16 items. I want to put back some photos in an album. But when I try to drag the image to the selected place a circular symbol with a fallen on line diagonally appears instead of the arrow cursor. Why can I not move the photos in the album?
Once you have selected an Album, the Album order, choose sort by drop-down list and then you should be able to move the images.
Thank you

Add more space to the ASM disk group
Hi all
I am new to the DBA role and also in a process of learning. I need your help in putting a space at the ASM disk group. My VMware admin will add disk space to the virtual machine, and then the Linux admin will add space on Linux servers. Finally, I think I need to rebalance the database disk group to view the extra space. I'm not sure of what all the steps involved in this process. I like to read the Oracle Documentation, but I'm blurry and hesitant. Please let me know the steps to follow to add the ASM disk group space.
We use
Oracle DB version 11.2.0.3.0
Linux version: 2.6.18 - 238.12.1.el5
Thanks for your help
No....
You don't need any instance restart. More when you add a disk to a diskgroup, all rac nodes can see.
just...
You should add a node and watch v$ asm_operation...

Create the ASM disk groups instance is not found
HelloI just started to learn Oracle, very inexperienced database in Oracle.
I have a problem to create an ASM instance. My environment is SUSe Linux Enterprise 11 64-bit, I am creating an instance ASM 11.2.0
1. when I create ASM instance, I couldn't find ASM disks, if an ASM Instance could not be created.
2. when I search on the internet on the creation of the ASM disk, it seems that I need to connect to the instance ASM as ASMSYS, but I have not an ASM instance is runing so ASM DISK groups has not can be created.
I feel that I'm at an impasse.
Could someone help me?
Thank you.
You may need to configure the udev subsystem to set permissions of the device and configure the parameter diskstring ASM or install Linux ASMLib, that supports both and more. In any case, you will need to provide more details and probably do some research to learn more about the basic concepts. To install Oracle ASM is not click and play.

I just tried to resize an ASM disk and although the reaction was "successful", it does not appear to have been any change.

I tried to restart the ASM instance, but it made no difference.

Thank you
SteveHi Steve,.
I think what happened occurred due to certain steps in your initial procedure, a corruption of ASM header that cannot be repaired automatically more. Therefore, check if ML Note 553319.1 - ORA-15036 when to start an ASM Instance - can be used to solve your problem, too.
Now, in order to avoid such things, I would make the following the next time:
Stop all except 1 ASM instance.
CHANGE Diskgorup RESIZE DISK - the disk that you want to resize.
Wait for the rebalancing that may occur finally.
stop this ASM instance
change the size of the disk to the disk level
restart all instances of the DSO.This seems to be the safest way to do it. A perspective HA, some optimization might be possible, I think.
Hope that helps. Thank you

If the video does not the restrictions of DRM (Digital Rights Management), so you can see just by changing the .mp4 extension allows it to be played in Windows Media Player, but if Apple added restrictions to the file DRM then you will be limited to such players as apple deems suitable to be used, probably iTunes or Quicktime.
