• How to solve the problem of 'ASM disk group is inaccessible' slave VM rac2?

  People,
  
  Hello. I want to install Oracle 11 g RAC 2 using 2 virtual machines (VM main rac1 and rac2 VM slave) with Oracle Linux 5.6 according to the website http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
  
  Grid and data base RAC have been installed successfully for VMS rac1 and rac2.
  I use the slave rac2 VM test data grid and CARS because rac1 disk is full.
  The problem is that the OCR file is not available or currupted in the rac2 VM slave. To know his reasons, I check permission on disc ocr as below:
  
  [ora11g@rac2 bin] $ pwd
  / U02/11g_db/ora11g/racdb/bin
  
  [ora11g@rac2 bin] $ srvctl start asm

• How to increase space in the ASM disk groups?

  Hi all

  I'm a newbie DBA in my team and today morning received an alert of OEM which:

  Target name = + ASM_ZEUS.techiebros.com

  Message = disk group DATA requires rebalance because at least a disk space is low.

  Any solution?

  To fix this, you can run this command: Alter diskgroup ASMDB add drive "here, the way of the new disk" Rebalance power 4 WAIT;

  After that, you can see through the v$ asm_operation;

  If the TM drive storage is full TM automatically deletes the version the oldest files for the new incremental backups can be made. Thus, in this case you cannot restore the versions that TM deleted because it takes more storage.

  Place your cursor on the image you want to make a picture, so that it displays in the preview window.   Then it spread, as an 'image' on your desktop.  File > share > Image.

  Another way is to take a screenshot of the image in the preview window, which will place a .jpg of the framework file on your

  You can expose the pic with pressing your pad mouse or track that you drag in the photo.

• How to move or migrate whole directories between ASM disk groups?

  Hi all!
  
  I'm playing with Oracle ASM and Oracle Database 11 g R1, I am a student. It's just for testing purposes.
  
  Features of the computer are:
  Processor: Intel Pentium 4 HT 3.00 Ghz.
  Memory RAM: 2 GB.
  Hard drive: 250 GB
  O.S.: Windows XP Professional Edition SP 2.
  
  I installed Oracle ASM, I have created an ASM disk group (+ FRA), I installed Oracle Database and I created a test database. The database works correctly on the ASM disk group. Days, I got help on the initialization parameters, DB_CREATE_FILE_DEST, DB_CREATE_ONLINE_LOG_DEST_1, DB_CREATE_ONLINE_LOG_DEST_2 and DB_RECOVERY_FILE_DEST, according to their function, I created another 3 ASM (+ FILES, LOG1, LOG2) disk groups. There are four initialization settings pointing to its corresponding ASM disk group. As you can deduce, for the time of installation of the Oracle database, I used the ASM '+ FRA' disk group and inside the directories were created: CONTROLFILE, DATAFILE, ONLINELOG, fichier_parametres, TEMPFILE, and the SPFile.
  
  My point is that I want to move or migrate the DATAFILE, fichier_parametres, TEMPFILE directories and the SPFile to '+ FILES', ONLINELOG and CONTROLFILE to '+ LOG1' and '+ LOG2', in this way, the ASM '+ FRA' disk group will contain the Flash recovery area only. What is the procedure for that?
  
  Thanks in advance!

  Hello

  There are two approaches that you can use, here are some
  -To move the data file, start the database in State of Mt.
  RMAN > copy datafile '+ FRA/xxx' to '+ FILES1 ";
  SQL > alter database file rename '+ FRA/xxx' '+ fichiers1/xxx. "

  -To move the temporary file
  SQL > alter tablespace TEMP add tempfile '+ FILES1' SIZE 10 M;
  SQL > alter database file temporary '+ FRA/xxx' drop;

  -To move onlinelog
  SQL > alter database add logfile Member '+ LOG1' group 1;
  SQL > alter database add logfile Member '+ LOG2' group 1;
  SQL > modify the members of database drop logfile "+ FRA/xxx."

  -To move controlfile
  SQL > restore controlfile on '+ FILES1' of '+ FRA/xxx. "
  the spfile update to reflect the new location of the controlfile

• Reinstallation of Oracle 11 g 2 RAC grid problem - ASM disk group

  People,
  
  Hello.
  
  I want to install Oracle 11 g RAC 2 with 2 Virtual Machines (rac1 and rac2 which BONES are Oracle Linux 5.6) in VMPlayer.
  
  I was installing Infrastructure of grid using runInstaller in the first rac1 VM from step 1 to step 9/10.
  
  On 9/10 in the wizard step, by chance, I touch the mouse, and the wizard disappeared.
  
  The grid in the 2 VMs installation directory is the same: / u01
  
  I have to make sure that everything is correct, delete the directory/U01 to 2 virtual machines and install again the grid in rac1.
  
  I realized that this is not the right way to remove/U01. The right way is to follow the tutorial
  http://docs.Oracle.com/CD/E11882_01/install.112/e22489/rem_orcl.htm#CBHEFHAC
  
  But I have deleted/U01 and must correct one by one. I reinstall the grid and get the error message in step 5 of 9 as follows:
  
  [INS - 30516] Please specify unique disk groups.
  [INS-3050] ASM disk group empty.
  Cause - the installer has detected the name of Group of disk already exists on the system.
  Action - specify the different disk group.
  
  In the wizard, the old disk group name is 'DATA' and his candidate records (5 ASMDISKs) are gone. I try to use another name "DATA2", but no ASMDISKs are "candidate records. For "All discs", it is impossible to select all ASMDISKs.
  
  I want to use the same disk group ASM 'DATA' and do not want to create a new disk group.
  
  My question is:
  
  How to make previous ASM disks and his group of 'DATA' therefore "Candidate records" who can use again?
  
  
  Thank you.

  Hello
  If you use oracleasm, then rebuild again asm disks.

  oracleasm deletedisk

• 11 GR 2 Grid Infrastructure install - with normal redundancy ASM disk group requires 3 disks?

  
  Hello

  I want to install 11 GR 2 grid Infrastructure in a new environment in cluster - 2 nodes). I use the 11.2.0.4 GI Installer on Oracle Linux 6.5 x 86-64

  However when it is in the installer of GI, it comes to choose the storage Option - I choose ASM disk groups.

  Then change the path of discovery to pick up my candidate ASM disks.

  I enter the disk group name SIR give Normal redundancy, choose 2 discs of candidate and then press < next > to Setup.

  However, I gives me the message

  [INS-30510] Insufficient number of ASM disks selected

  The number of selected disks was inadequate for the level of redundancy selected

  For a disk group with redundancy level "Normal" disks at least "3" are recommended

  I always thought that Redunancy Normal required only 2 discs and high redundancy requires 3 disks?

  No idea what is gpoing?

  Thank you

• Difference between ADVM Volume and filesystem ACFS ASM disk group

  Q1. What is the difference between an ASM disk group and a Volume of ADVM?

  In my opinion, an ASM disk group is actually a logical volume to the database (including the FRA files) files.

  11 GR 2 appears to have introduced the notions of volumes ADVM and filesystems ACFS.

  11 GR 2 ASM disk group can contain:

  • ASM disks
  • Volumes ADVM
  • Filesystems ACFS

  Q2. ADVM volumes appear to be dynamic volumes.

  However is it therefore not effectively overlaying a logical volume (the volume ADVM) under ASM disk group (conceptually a logical volume as well)?

  Even worse, if you left the ASM disk group redundancy in hardware RAID / SAN level (as recommended Oracle), you actually have 3 layers of logical disk? (ASM on top of ADVM on top of RAID/SAN)?

  Q3. If it is 2 layers of logical disk (i.e. on top of ADVM ASM), what makes this better than 2 layers using a 3rd party volume manager (for example the DSO at the top of the 3rd party LVM) - something Oracle encourages against?

  Q4. ACFS file systems, seem to be file systems clustered for not including ORACLE_HOMEs database files, application exe etc (but NOT GRID_HOME, OS root, OCR or voting records)

  Can you create / modify filesystems ACFS using ASM.

  The diagram of topology of oracle for ASM in ASM 11 GR 2 administration guide, says ACF in ASM. I'm not sure about that if ACFS belongs to ASM or ASM is located at the top of the ACF?

  Q5. Connected to the 4th quarter. There seems to be a number of different ways, ACFS file systems can be created? Which of this is the valid methods?

  • Thanks to ASM?
  • through native OS file system creation?
  • through OEM?
  • through acfsutil?

  my head explodes

  Any help and clarification appreciated

  Q1 - volume ADVM is a type of special file created at the DG of the DSO.  Once created, it creates a block device on the BONE itself which can be used as any other block device.  http://docs.Oracle.com/CD/E16655_01/server.121/e17612/asmfilesystem.htm#OSTMG30000

  Q2 - the asm disk group is a group of disks, not really a logical volume.  It combines the attributes of both when it is used for purposes of database as the database and some other applications know how to talk about Protocol 'ASM '.  However, you won't find all the versatile applications that can do.  In addition, some clients prefer to deal directly with files and devices of volume systems which ADVM is forced to make.  In your thinking, you have 3 layers of logical disk, but each of them provides features and different attributes.  This is not a bad thing, though, as each has a slightly different purpose - os file system\device, specific database and storage-centric.

  Q3 - ADVM is specifically developed to extend the features of the DSO for use by General applications of BONE.  It includes the performance of database features and is tuned to work well in this situation.  Because it is developed in-house, it benefits from the design of ASM model.  In addition, rather than having to communicate with several vendors for support, your support is limited to calling Oracle, a single window.

  Q4 - you can create and modify filesystems ACFS by using command line tools and the ASMCA.  Creation and modification of logical volumes coming through SQL (ASM), asmcmd and ASMCA.  EM can also be used for the two elements.  ACFS is located at the top of the ADVM, which is a file in an ASM disk group.  ACFS is aware of the characteristics of the ASM\ADVM volumes and tunes it's IO make best use of these features.

  Q5 - several ways:

  1) connect to ASM with SQL, use 'alter diskgroup add volume' as Mihael points out.  This creates an ADVM volume.  Then, put in shape volume using the "mkfs" (* nix) or acfsformat (windows).

  (2) use ASMCA - a GUI to create volume and a file system.  Probably the easiest if your head is explosion.

  (3) use "asmcmd" to create a volume and 'mkfs' to put in shape file ACFS system.

  Here is information on the ASMCA, with examples:

• 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.

• Standby Database ASM disk groups

  Hi guys

  I wonder if someone can tell me - a database of Eve should have a similar configuration to its ASM disk groups?

  My production database has groups of two disks, one for data and one for temp.  Can I go out with one single diskgroup in my database pending or do I need both the same name as the production database?

  See you soon

  Simon

  You need not the same configuration between the primary and standby.  But I prefer to do the the same because it is easier to manage.  Oracle recommends also 2 groups in any case.

  Hope that help

• Question about the use of size mixed with ASM disk groups

  I support a RAC 10 g 10.2.0.3 running and using ASM cluster. We currently have a group of data disks, which is 600 GB in size, consisting of 3 individual raw disk 200 GB devices. The RAC cluster runs on a server pSeries IBM using AIX 5.3
  
  I need to add more space, but the system administrator can give me only 100 GB in the new raw device. What will be the impact, if any, the addition of this feature of smaller crude disk in the same data ASM disk group? I understand that ASM is trying to "balance" the general use of each raw device. ASM still works very well, or will he constantly try to rebalance the disk group because the a raw device is only half of the other three? Any help and advice would be greatly appreciated. Thank you!

  It works, I do the same thing in a production database. What happens is, asm will distribute data on the size of the disks. 200 GB drives will get two times more data than the 100 GB drive. The downside is that it will also result in an unequal distribution of the IOPS / s: adults discs will be achieved more often.

• How to remove the msg: "consolidation of disks of virtual machines is necessary."

  Hi all

  I implement vSphere 5, and I have the following message displayed in the vCenter (virtual machine Summary tab). Does anyone know how to remove the message without consolidating the snapshot?
  ----------------------------------------------------
  "Consolidation of disks of virtual machines is necessary."
  ----------------------------------------------------

  I think vCenter is detect the Delta for this virtual machine and warning me that I have to consolidate the snapshot. However, I do not want to consolidate the snapshot because the database is still running when the snapshot was taken, and there is a great chance that the data will be corrupt when I consolidate this delta disk file.

  I looked towards the top of the Knowledge Base, but it does not say how to stop the message without actually consolidate the snapshot.

  Thanks for you information in advance!

  the message will disappear as soon as snapshots are consolidated.  There is no way to remove the message otherwise.  Just think of it as a reminder that the snapshots should be engaged.
