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.

(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.

    Yes. You will need to first 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.

    Since you are using OCR and VOTING DISK on ASM, it is not possible only stop ASM and keep cluster running.

    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...

    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.

  • Install RAC 11 GR 2 and apply the patches with the new Option of software updates YES

    Anyone tried the installation with the new Option of software updates?

    I'm going to install grid RAC 11 GR 2 and I intend to do the following steps:
    (1) install the Oracle Grid Infrastructure 11.2.0.2 patch group
    (2) make all configurations with YES
    (3) create ASM disks
    (4) install Oracle Database 11.2.0.2 software only
    (5) apply recommended patches 11.2.0.2.2 Oracle (12311357) and 12431716. (Ref. MOS doc [756671.1 ID])
    (6) create the RAC (advanced option) with DBCA database

    With these steps:
    Grid and ASM disks would be configured without the recommended patches, but the database will be created with applied patches.

    I would not do a "Software only" install IM and then apply the patches because later I would have to manually do all the configuration steps.

    If I use the Option of YES software updates to apply patches, YES makes the adjustment, and then I would set up the GRID with YES?

    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.

    Hello, Arturo.

    Negotiators and GNS are independent of each other

    From 11 GR 2 onwards, files with right to vote can be hosted on ASM. And the upcoming ASM to cssd demon. And for the cssd start the cluster needs to access files with right to vote.

    These voting files location information is stored in the profile of negotiators (grid Plug n Play) file.

    GNS, is for the resolution of the cluster name. For customers outside the cluster to find the virtual servers in the cluster, we provide a Naming Service (GNS) grid. It works with any level superior DNS to provide names can be resolved to external customers. DHCP provides dynamic configuration of the IP address of hosts, but does not provide a good way to produce names which are useful to external clients. Accordingly, it has been rare in the server complex. In Oracle 11g release 2 Clusterware (11.2), this problem is solved by providing clusterwares own service name in the cluster and this connection resolution DNS that is visible to customers.

  • 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...
