• Backup of the OCR and voting disk

  Hello
  
  A few quick questions related to the backup of the OCR (via ocrconfig-export) and vote (via SD) disc.
  
  
  (a) I can back up disc OCR and vote while the database is running.
  
  (b) do I need login as root for the backup of the OCR disk and vote.
  
  
  Thank you
  C.

  Hello

  I recommend you read the TechNote below, if you use Clusterware 11.1 or earlier:

  * Information on OCR and drive to vote in Oracle 10 g Clusterware (RAC) [ID 1092293.1] 2 *.
  Follow these topics:

• 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

• 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.

  You can layer does not to futz with things?

• 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?
  
  -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...

  Thank you

• 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?

  The following ocrdump utility examples extract various types of OCR information and write it to various targets:
  
  ocrdump
  Writes the OCR content to a file called OCRDUMPFILE in the current directory.
  
  ocrdump MYFILE
  
  $ ocrdump
  
  $crsctl query css votedisk

• Apple and legacy applications file system?

  Hello

  I heard that Apple will release Apple (SATF) filesystem in 2017.

  I'm sorry, I have no idea what it means for my system. Will be my apps (I got a few apps too, and the apps that I don't have form the Mac App Store) continue to work?

  Thank you for your help.

  The release of a new file system has nothing to do with your applications, so they will still work correctly if you start to use it (even if you need to check that your applications are supported whenever you upgrade OS X)

• Corrupt boot drivers and XP NTFS file system

  The system event log shows that I have files corrupted ntfs and suggests also I have the drivers corrupt boot and MS says I should check and repair if necessary - but how do I do this?  There seems to be nothing in the knowledge base on this issue. I have also a no momentum for a service of IP security, but maybe it's just the result of corrupted file system and I will need to recheck once I fixed the underlying problem. Advice please?

  There is also a logon successful for 'Anonymous' on several occasions that may or may not indicate a virus, but may also be the result of damaged files - messy!

• CPU, RAM and disk, file system information for the data, logs, temp, Archive for database

  Hello gurus,
  
  How can we see what size of CPU and RAM for the database? According to the previous steps of this great site, I could able to do
  

  SQL> show parameter sga_max_size
  
  NAME                                 TYPE        VALUE
  ------------------------------------ ----------- ------------------------------
  sga_max_size                         big integer 800M
  SQL> exit

  Therefore, the size of the RAM for the database to which I have connected
  

  rootd2n3v5# ioscan -kfn |grep -i processor
  processor    0  13/120         processor CLAIMED     PROCESSOR    Processor
  processor    1  13/121         processor CLAIMED     PROCESSOR    Processor
  processor    2  13/122         processor CLAIMED     PROCESSOR    Processor
  processor    3  13/123         processor CLAIMED     PROCESSOR    Processor
  rootd2n3v5#

  The one above was the command give the OS level that I don't know what information he gives and what database, since there are 12 databases on this server.
  
  How can I get the CPU information?
  
  And where can I find information for information of system data files, logs, temp, Archive?
