• 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

  
  Hello

  I 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.

  Thank you

  Hi 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

  but I wanted insurance with people with experience as you go this drive on differnet LUN will not impede performance.

  A LUN is a logical unit - it may be a single physical disk. It may consists of 20 physical drives. If the LUN itself does not determine the performance. Performance is determined by the parts in movement under it.

  Multiple LUNS to the same diskgroup using or the volume of file system is a common practice. If this would be a problem (performance or otherwise) depends on the cloth under the LUN.

  For example, a logic unit number could be RAID5 and another logic unit number can be RAID0 + 1. Mixture of different RAID levels is not really a good idea.

  A LUN can be a storage on a San and accessible via the fiber channel. Another logic unit number could be an iScsi device, accessed through intellectual property. Mix very different storage architecture and storage protocols are not a good idea.

  A LUN can be RAID0, through fiber double channels connected to a switch, for the storage of 1 storage server. Another logic unit number can also be RAID0 and accessible through the same fiber channels and switch, but since the storage server 2. Whereby the RAID levels are the same and the storage Protocol and infrastructure the same - and that will not only make a compatible mix, but can actually increases the redundancy if you use these as disk mirrors ASM (which means that ASM can lose the server storage 1 or 2 and still works).

• file data and the ASM disks.

  Hi experts,

  We have a situation where one of the data file has been corrupted. Can we find the related ASM disk... no request to find that the drive associated with asm (physical disk) will be useful...

  because for example I need to find the disk related asm for the data file: +disk_group_1/my_dir/my_file.dbf

  Kind regards

  Spengler

  Hi Spengler,

  In ASM we saw exactly the same as database.

  What you do is,

  Your file "+ disk_group_1/my_dir/my_file.dbf" is an alias, so go to this directory through asmcmd and ls - lt and get the original physical file named ..

  + Now check where the distribution of the is distributed for this file.

  To do this, run the command UESA (read-only)

  UESA - diskstring ''-'' dump - noimage

  This will generate a new directory.

  on the inside you will see 2 files.

  + Now open the .map file and find this filenumber, it is like F00000NNN

  Where NNN corresponds to file_number

  + See related disc of the map as N00n file, then look for this file report.txt N00n.

  -This will give you disc associated with this asm file.

  Kind regards

  Change your PFILE file to specify that IFILE = 'location_of_spfile. '

  OR

  use STARTUP PFILE = "location_of_spfile."

  Ensure that the spfile has the specific parameters of 2nd instance defined properly.

• 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?
