• How to customize the location of OCR and voting disks.

  Hello

  Today I installed the first time CARS (gR 11, 2) on HP UX 11-31 with ASM. Customer wishes to place OCR and voting disks in a specific disk group.  Today during the installation, I couldn't find an option to indicate the location of the OCR and voting disk. That's why I continued with the default location and the installation is completed successfully. Now my question is

  (1) is it possible to change now?

  (2) I have a facility more tomorrow, is it possible to specify the location before you start the actual installation. Can any body tell me the way to do this?

  In parallel, I check in the net as well...

  Thank you in advance...

• 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?

  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...

• May read IBM easy level affect OCR and voting disk diskgroup?

  Hello world

  I have an Oracle 11 g (11.2.0.4) CARS on a Solaris 10 Sparc Server, we also have a midsize v3700 IBM and we had no problem until last Friday, so far there has been activated the easy level feature since we connected two drives in the solid state it. Minutes later the diskgroup DG_GRID that stores OCR and voting disks that are non-mounted and the resource ora.crsd changed in DISCONNECTED state.

  We have that at this time, it was a question of synchronizing the disks, but this situation is repeated every day since last Friday,

  The alertlog displays these messages:

  2015-04-30 00:48:09.228:

  also, when I checked the crsd.log I can read the following lines:

  So I noticed the diskgroup DG_GRID was down, I re - it easily mounted without warnings and errors, and then I started the resource ora.crsd, according to the journal of alerts, everything was ok

  The fact is, it is events every day approximately at the same time (00:30-00:45) and he started since the easy tier feature has been enabled in the SAN.

  I want to know is there any recorded case that happened with this feature? How can I solve this?

  Any help will be appreciated.

  Looks like maybe even cause high latency but low IOPS / s

  In other words, san won't answer the door immediately because he's busy household and crsd looks forward to someone to answer the door.

• 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.

• 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

• Confusion with the file system OCFS2 OCR and voting disk RHEL 5, Oracle11g,

  Hi all
  
  I am trying to install the Oracle 11 g 3 node RAC database
  
  The environment on which I must make this implementation is as follows:
  Oracle 11g.
  Red Hat Linux 5 x 86
  Oracle Clusterware
  ASM
  Storage EMC
  250 GB of disk storage.
  SAN
  
  From now on, I am installing Oracle Clusterware on 3 nodes.
  
  I performed these tasks for cluster installations.
  
  1 configure the kernel parameters
  2 configure the user limits
  3 edit the /etc/pam.d/login file
  4 set up the groups and users to the operating system for Oracle Clusterware
  5. configure the environment Clusterware Oracle owner
  6. install the rpm CVUQDISK package
  7 configure the Hosts file
  8. check the network configuration
  9 configure SSH on all the Cluster nodes (equivalence of the user)
  9 enable SSH on all the Cluster nodes (equivalence of the user)
  10 installing Oracle Cluster File System (OCFS2)
  11. check the Installation of the (OCFS2) Oracle Cluster file system
  12 set the OCFS2 (/ etc/ocfs2/cluster.conf)
  13 set up the stack of Cluster O2CB for OCFS2
  
  BUT, here again the after that I'm a little confused on how to proceed. The next step is to format the disk and mount the OCFS2, directories of software... so, create etc.
  I asked my administration system to provide me with two partitions so that I could get in shape with the OCFS2 file system.
  
  He wrote telling me.
  
  * "Is what you want before I do it?" *
  
  * / dev/emcpowera1 is 3 GB and OCFS2.* format
  * / dev/emcpowera2 is 3 GB and OCFS2.* format
  
  * Those who are big enough for you? If not, I can re-size and re - format the *.
  * before I climb on the servers.*
  * the SAN is shared storage. / dev/emcpowera is one of the three LUNS on *.
  * storage is shared, and it is 214 GB. At the moment there are only two *.
  * partitions on it - the ones I have listed below. Can I repartition the LUN everything *.
  * as you want it.*
  * Where do you want that these climbs to: *.
  
  * / dev/emcpowera1 *.
  * / dev/emcpowera2 *.
  
  * I thought if this mounting technique would work as follows: *.
  
  * emcpowera1: / u01/shared_config/OCR_config *.
  * emcpowera2: / u01/shared_config/voting_disk *.
  
  * Let me know how you would like that mounted. » *
  
  Please recommend me what I should pass so that I can ask him exactly the same.
  
  My second question is, as we use the DSO, for which I'm going to configure ASM after clusterware installation, do I install Openfiler?
  PLS, check the environmental information that I provided above and make recommendations.
  
  As of now, I am using Jeffery hunters guide to install the entire installation. You think the installation guide everything is fine with my environment?

• How to make a backup of the drivers and applications

  I have a HP Pavilion Desktop PC all-in-one 23-B115EA, originally with Windows 8 installed which I have updated to 8.1 of the store.  After a problem, I was advised to create a System Image on an external hard drive, what I've done.  I also have a recovery disk including the recovery on a USB Partition and a new Restore Point.

  The reason why I write, is that what follows has been also sugested "Furthermore, make a backup of the drivers and Applications.» Still, if the hard drive needs to be replaced, you will need to install all the drivers and perhaps some applications again for which you have this backup. "I don't know how to do on the PC and I was wondering if it was possible.

  Best regards, Mike-01

  Mike, you're welcome.

  I know that in the past, there are third-party programs that could back up the drivers, but I could not find one to win 8.1.  With respect to applications, the CD recovery and Image will be all you need.

• backup of the OCR

  Hello
  melting procees takecare of ocr backup automatically.

  The CRSD process that creates backups has also creates and maintains a backup of the OCR for each full day, then at the end of a week a full backup of the week.
  So, there is a robust backup taking place in the background. And you guessed it right; You cannot change the frequency of backup. It's supposed to protect you, the ADMINISTRATOR, so that you can copy these backup files generated at least once a day to another device where resides the primary OCR. These files are located in % CRS_home/cdata/my_cluster.

• What is the difference between a backup of the plant and a recovery disk?

  For me a simple question, so I hope a simple answer.

  When I got to my laptop that I created a USB using DBR recovery. It is a little more than 8 GB in size and is appointed SYSRECOVERY.

  At that time there I didn't create a backup of the plant.

  Having recently been read on things related to the re-establishment of a system in case of disk failure hard etc, I saw that Dell has said you must create USB recovery media and a backup of the plant. So, I got a new USB and today created a backup of the plant.

  Looking at it, it is also called SYSRECOVERY and both have exactly the same list of files and folders and have almost the same size.

  So just what is the difference between these 2 options (if any)?

  Or do I now have 2 USBs that will do exactly the same work to restore my laptop computer provided that the factory?

  Case there is no difference, why Dell offer both (and recommend you create both)?

  Thank you

  Technically speaking a recovery media and backup of the plant are the same. But according to the post that you saw at Dell, recovery media is a backup of backup from the factory with the files and applications that you added later. Therefore, to be on the safe side, Dell recommends to create a backup of files and software that have been added later (or is not part of the default configuration).

  The factory backup contains all drivers and software according to the configuration of the PC, and that were pre-installed on your computer.

  Generally, Windows failure, you can use factory backup media to restore the PC without affecting your personal files and software. In the event of hard disk failure, where the hard drive is replaced, recovery media will be useful to restore Windows as well your files and applications.
