  We have 2 instance of node CCR on win2003 64 bit with three starts DATA, BKUP + FRA.
  We ordered new servers until then I won't have any instance test but that the production to work on.
  I'm taking care of files db, ctl, spfile, arcivelog files using RMAN.

• can ocr and vote files resident on the same disc?

  Hello

  We use 11.2.0.3 on linux.

  When I created OCRVOTE diskgroup with 5 raw disks, oracle created default 3 discs with right of vote and rest 2 discs to keep the OCR files.

  But when I created OCRVOTE diskgroup with 5 raw disks, I have found that all 3 disks are votingdisks and OCR, also located in the same diskgroup.

  
  

  How can it be possible? That is to say, is it possible for OCR files be placed disks marked as voting disk?

  Kind regards

  Check: RAC: frequently asked Questions (Doc ID 220970.1)

  How the registry of Cluster Oracle (OCR) is retained when using ASM?

  https://support.Oracle.com/epmos/faces/DocContentDisplay?ID=220970.1

  > Oracle instructor is to show that scopes are spread over only 2 discs among the 8 discs.

  As far as I understand:

  What Oracle instructor shows an example of how is stored the mirror of the measure where OCR has been stored, it has used a simple example with only 2 measure showing a measure and a mirror of measure on different failgroup, does not mean wich used only OCR 2 measure or use only 2 asmdisk.

  In this case, Oracle will use all failgroups placing a (primary) measure in each failgroup and store a copy of the measure (mirror) in a different failgroup.

  Concerns about redundancy (that was the point):

  Votedisk you have a right to vote in each asmdisk.

  OCR store using a diskgroup redundancy with normal you have a measure mirrored in a different failgroup. (she)

  How to measure Oracle Store OCR?

  She spread file OCR on all disks if ASM Diskgroup configuration allows do.

  If you have an OCR with 300 MB and store you it in a Diskgroup with external redundancy using 1 MB AU_SIZE and the size of the measure is 1 MB ASM spreads extended across all the disks in the Diskgroup storing bodies in all the balancing asmdisk.

  But we should consider the OCR file size and configuration of the ASM Diskgroup

  The ASM file content is stored in a disk group as a set or collection, extensions of data that are stored on individual disks in disk groups. Each extension resides on an individual disk. Extensions are made up of one or more allocation units (to THE).

  When you create a disk group, you can set the Oracle ASM with A unit allocation size U_SIZE disc of the group attribute. The values can be 1, 2, 4, 8, 16, 32 or 64 MB

  Therefore, if you create an external redundancy diskgroup with 8 ASMDISK using 64 MB AU_SIZE, EXTENT_SIZE is 64 MB and size of 100 MB Oracle will use OCR only two ASMDISK using 2 scope of 64 (128 MB) does not matter if you have 8 DISKS ASM.

• 2 questions: backups of disk XP and EULA talk about more than 1 CPU.

  2 questions: The Windows XP Home EULA says that I can not use the program on more than one CPU. Does this mean that I am breaking the agreement by running on a dual-core CPU? Second question, it is good to re - install Windows XP from a backup copy, when I lost the original disk but still have a valid product code?

  First question: a dual-core CPU has two processing cores, packaged in a single module.  It counts as a single processor for Windows XP license.

  Second question: Yes.

• RAC + ASM: Grid OCR and VotingDisk - installer puts on simple Diskgroup

  Hi all
  
  It seems that the grid Setup does me not to choose/create more than 1 (one) Diskgroup OCR and voting disk. Am I missing something, or is it best practice?
  
  I thought it would have been good to multiplex OCR/vote at least 2 different ASM starts...
  
  I'm also confused because the oracle documentation says that, for most installations, starts at only 2 would be enough ("Data + index + LOBs" and "FRA").
  
  In a matter of fact, what I was planning to do is have 3 starts in this configuration (data, index + LOBs, FRA) and have OCR and vote multiplexes on TWO 'data' and 'Index + LOB '. But now I don't know if the sharing of data and indexes have a meaning, ASM...
  
  (1) that it makes sense (the fact I want to multiplex OCR + vote)?
  (2) how to achieve the result desired during the installation, if possible (multiplexing OCR + vote)?
  (3) to other recommendations (for example using a 4th Diskgroup, or should I use only 2 of them)?
  (4) with ASM, is it still wise to separate the data and the indexes on different starts?
  
  Thanks for your help

  My recommendation: this first diskgroup you can use to store your files with the right to vote and the OCR, and later, you can create another small diskgroup add OCR and move ASMSPFILE to this new diskgroup.

  Vote files can be stored in a single diskgroup.

  I thought it would have been good to multiplex OCR/vote at least 2 different ASM starts...

  (1) that it makes sense (the fact I want to multiplex OCR + vote)?

  I really do not recommend putting database files and clusterware together. This may disturb the management of the environment and could dowtime. (for example, you can never stop the diskgroup)
  for example: files with right to vote are not stored in the diskgroup (+ data), they are placed directly into asmdisk, then in case of maintenance in the diskgroup, for example to increase the size of the lun, you can just delete the asmdisk, you must move the files with right to vote in another place and realize the diskgroup maintenance.

  Dowtime? Yes... You can move only the voice and the ocr without interruption of service, but to move ASMSPIFILE, you need downtime. This is necessary for ASM using new SPFILE and release the old Diskgroup. * ORA-15027: active use of the diskgroup opposes its release (with no connected customer database) [ID 1082876.1*]

  (2) how to achieve the result desired during the installation, if possible (multiplexing OCR + vote)?

  You can't get the result desired during installation, but you can reconfigure at the end of the installation.

  Read:
  {message: id = 10028550}
  I recommend you read the entire thread above

  (3) to other recommendations (for example using a 4th Diskgroup, or should I use only 2 of them)?

  My recommendation, OCR and ASM SPFILE (diskgroup1), MIRROR of the OCR and VOTING QUEUES (DISKGROUP 2), FILES of DATABASE (DISKGROUP3), ONLINELOG (4 Diskgroup in an array with RAID 10) and FRA (DISKGROUP 5)

  Read:
  {message: id = 9676881}

  (4) with ASM, is it still wise to separate the data and the indexes on different starts?

  If you use different tables in the storage of data and indexes, perhaps, but I recommend doing this only if you have performance issues and you did the test and know there will be benefits if you don't have a reason why I do not recommend this because it increases the administration of storage, ASM and data base.

  Read about the use of different tablespace for data and indexes.
  {: identifier of the thread = 2189138}

  More 1 diskgroup using database files must be careful, because the Oracle restore can only use a single diskgroup.

• Oracle 11g r2 Linux backup voting disk and OCR

  Hi experts
  
  I want to back up the voting disk and OCR for our Oracle 11 g r2 on broadband, what is the best way? Thank you

  Hello

  Oracle Clusterware automatically creates backups of OCR every 4 hours. At all times, Oracle Clusterware still retains the last 3 copies of backup of the OCR that are 4 hours old, aged 1 day and 1 week.

  If you want to save your metadata ASM which includes (OCR and voting disk) tape
  You can create a script to let the backup agent judge with the backup job, and then copy it to the tape library

• OCR and voting disk

  Hi all
  
  What is the difference b/w OCR and voting disk

  The voting disk is a file that manages information about the node membership and OCR is a file that manages the cluster and RAC database configuration information.

  Vote of disc - Oracle Clusterware uses the drive to vote to determine which instances are members of a cluster. The voting disk must reside on a shared disk. Basically, all the nodes of the RAC cluster register their heartbeat information on teas voting records. The number will determine the number of nodes in the RAC cluster. They are also used to check availability of instances at the JRC and remove the unavailable out of the cluster nodes. It helps prevent the condition "split brain" and maintains intact the database information. The split brain syndrome and its effects and how it has been successful in oracle is mentioned below.
  For high availability, Oracle recommends to have a minimum of three disks with voting rights. If you configure a single voting disk, then you must use external mirror to provide redundancy. You can have up to 32 disks with right to vote in your cluster. What I could understand the odd value of the number of disks to vote is that a Noah should see voting disk to continue to operate, so with 2 maximum number, if he sees that 1, is not the maximum value but one half of the value of the voting disk. I always try to look for more on this concept.

  OCR (Oracle Cluster registry) - is located on the shared storage, and maintains information on the configuration of the cluster and cluster database. OCR contains such information which instances of database nodes and services that is running on what database.

  Registry of Cluster Oracle (OCR) is such a component in 10g THAT CARS used to store the cluster configuration information. It is a component of shared disk, usually placed in a shared gross volume that must be accessible to all nodes in the cluster. The demon OCSSd manages the configuration information in the OCR and maintains the changes in the cluster registry.

  ocrcheck is the command to check the OCR.

• OCR and voting disks (vd) are in ASM, I can stop the ASM instance?

  Hello
  
  I have two RAC nodes in the program of production installation and test setup. OCR and voting disks (vd) are in ASM, I can stop the ASM instance?
  
  -Kumar

  Hi Kumar,

  No, we can't.

  Best practice is that you need to stop the battery Oracle Clusterware on the node on which you must stop the Oracle ASM instance.

  Use "crsctl stop cluster node_name - n" or "crsctl stop crs" for this purpose.

  It could be that useful...

• About size OCR and voting disk

  Hallo,
  
  I have a simple question for OCR and voting disk in a configuration of RAC 10 g / 11g:
  official documentation talks about sizing OCR and voting disk approximately 280 MB, but they mean each OCR and voting disk LUN?
  
  In other words, for 2 OCR and 3 voting disk, I need 280 * 5 MB (o several single LUN)
  
  Is it so?
  
  THX in advance

• How to OCR and the drive to vote of raw devices for ASM diskgroup

  Hello
  
  I plan to upgrade my environment clusterware/ASM 11.1.0.6 to the grid
  infrastructure 11.2.0.1 on Solaris sparc 64-bit.
  I also plan on spending the OCR and discs of raw devices to ASM voting
  starts. But how to do? When should I do: upgrade
  process or after the upgrade? When should I start?
  
  Thank you

  create a disk group or use an existing disk group that matches your redundancy needs

  To ocr asm
  ===============
  1 ensure that the clusterware version 11.2.0
  # crsctl query crs activeversion
  Oracle Clusterware version active on the cluster is [11.2.0.1.0]

  2. replace the OCR file by the asm disk group
  #ocrconfig - replaced - replacement<+ASM diskgroup="">

  3 remove the old file ocr
  #ocrconfig - remove

  4. check the integrity of the ocr
  $cluvfy comp ocr n - verbose

  SE asm votedisk
  ======================
  1. Add the voting disk to the asm disk group
  #crsctl replace votedisk<+asm disk="" groupname="">

  Note: According to the disk group redundancy the required number of ocr and voting disk files will be created
  Normal: 2ocr, 3voting disc
  For the great: 3 ocr, voting 5 disc

  do not backup the ocr/votedisk dd in 11.2.0

• Backups taking over 130 GB of 160 GB, getting 'Startup Disk Full' and the computer does not. Help!

  I fight for free space on one of my older iMacs work and I am to the point that we cannot use it because the startup disk is full.  I've recently upgraded to Snow Leopard OSX Lion (10.7.5) so I could update our video editing software, Adobe Premier.

  We run all our video projects on external hard drives, which does not have the boot disk space and are always good on the erasure of files from the Recycle Bin, audio, photo and video so that they are not get bogged down.  About this Mac shows my 160 GB boot drive contains 8.87 GB Audio, 7.69 GB, 6,49 Photos GB movies, 6.58 GB Apps and a huge 129.34 GB of backups.  I have time Machine backed up on an external hard drive and can't seem to find out where these files are to be removed from the startup disk.

  Turn off time Machine and restart does not clear space.  I have even made the Terminal kill command no matter what auto backups, deleted device and old library version in iTunes, etc.  and I have no backup label appears when I bring up the screen of star wars of the time Machine. I went through so many stages and suggestions to get this machine working again.  I understand these backups are supposed to remove themselves automatically, but why are there still first place if I save on the outside?

  PS I'm not very computer savvy, but I know my way around.  Additional suggestions are appreciated - please let me know if I need to provide more information.
