ASM Configurations

Hi,
I am new to configuring ASM,
Can you tell me how to start from scratch like what kind of disks required. which raid level should be configured, which one is the task of sysadmin and which tasks will be performed by dba?
My operating system is solaris 9 x86 and database would be 10gR2.
We are going to deploy data warehouse environment.
alomost 100gb RAM is available (expectedly from 80gb to100gb ram).
please help me understanding the ASM configuration and disks knowledge along with RAID levels.
Note: we have 600GB hard disk (6 disks 100gb each).
Thanks all........

  • How to reuse the same disk (partition) for next ASM configuration?

    Hello All,
    I had successfully installed and configured ASM instance once, but I need to do a reinstallation and I would like to use the same disk (partition) as with previous ASM configuration.
    The disk path used was: /dev/rdsk/c1t3d0s7
    I have to regretfully admit that I may not have used the right ASM un-installation procedure. I ran installer and opted to de-install products. Consequently, I had removed ASM home. Now, when I running new ASM installation, everything goes fine until the screen where I should select disks for ASM configuration. Unfortunately, I see the /dev/rdsk/c1t3d0s7 with status > MEMBER < and I can't select it for the new ASM installation.
    I will really appreciate if anyone can let me know how to change status from MEMBER to CANDIDATE.
    Thank you for your time.
    DanielD

    Overwrite the first several MB of the partition with /dev/zero.
    So, use this command:
    # dd if=/dev/zero of=/dev/rdsk/c1t3d0s7 bs=1024k count=10
    That clears out the ASM header on the disk so that it looks like a clean disk again.

  • Database is not created on ASM configured Disks

    hi,
    I have installed Oracle 11gR2 Grid Infrastructure and Automatic Storage Management for a Standalone Server through "Grid" user. After then I install Oracle Database 11gR1 Software through "Oracle" User. There is no problem occure during the installation of these software. The OS is OEL-5.4. AND
    ASM configured Disks are "DISK1, DISK2 AND DISK3" and the Group Name is "+DATA".
    The Problem is when i want to create Database and chose ASM configured disk for Database storage, at the database creation process on 27% an error occur that is "ORA-03114 Not connected to Oracle". Sir but when i chose File System for Database Storage, Database created successfully.
    Sir i am new in Oracle Grid Infrastructure and ASM please help me.

    Hi buddy,
    Are there errors in the alert.log of RDBMS istance, and what about traces ? Have it been generated ?

  • Oracle database 10g RAc an ASM configuration

    Hi all,
    I want to ask to everybody something about Oracle 10g RAC and ASm configuration. We plan to migrate to Oracle 10g from 9i, and we will begin configuring oracle but we have to decide which configuration are the best.
    Our materials are bellow:
    Hardware: RP 3440 (HP)
    OS : HPUX 11i Ver 1
    Storage: EVA 4000 (eva disk group)
    The problem is:
    Our supplier recommand us to use HP serviguard + HP serviceguard extension for RAC+ RAc and Raw device as configuration.
    But we want to use Oracekl Clusterware + RAC + ASM
    My question is if anybody know what is the best configuration, we want to use ASm.
    Can we use HP serviguard and ASM.
    Some documentations or link explain oracle RAC and ASM configuration will be appreciate.
    Thanks for your help.
    Regards.
    raitsarevo

    Hello,
    there's no extra RAC software package, but the option is only offered, if one of the supported cluster layers for the respective OS has been installed before.
    10.1.0.3 looks like a complete redesign, but anyway it is a patch, you have to install 10.1.0.2 first.

  • ASM Configuration

    Hi Everybody,
    My question is:
    Is it possible to configure ASM using shared file system on RAC other than configuring raw devices . If it so how to do it?
    Environment:
    OS: Sun SPARC Solaris 10
    SUN Servers:V490
    Number of Nodes: 2
    Storage Server:3150
    Switches:SAN
    RDBMS: Oracle 10.2.0 RAC
    Clusterware: Configuring Raw Devices for OCR and Voting Disk.
    How to configure ASM on Shared Storage for database files as we are not using Third party clusters?
    What are the possible storage options for ASM as per my requirement?
    I seen in document it is very dfficult to manage and administure ASM configured using RAW Devices?
    in both the cases kindly provide me steps how to do it by using DBCA.
    Is it necessary to use recovery area on ASM?
    Waiting for your favourable reply from RAC experts.

    Hi,
    Steve Karam has some great notes on this:
    One thing to remember is that ASM is not RAID. Oracle portrays ASM as a Volume Manager, filesystem, miracle, whatever you would like to call it, but in reality it is no more than extent management and load balancing; it scatters extents across your LUNs (1MB stripe size for datafiles/archivelogs, 128k stripe size for redo/controlfiles). It also provides extent-based mirroring for extra redundancy.
    This benefits us in a couple ways. First, remember that your OS, HBA, or other parts of the host driver stack may have limits per LUN on I/O. Distributing your extents across multiple LUNs with ASM will provide better I/O concurrency by load balancing across them, eliminating this bottleneck.
    Second, carving into multiple LUNs allows multiple ASM volumes. Multiple volumes help us if our hardware has any LUN-based migration utilities for snapshots or cloning.
    Third, you may end up with multiple LUNs if you need to add capacity. ASM allows us to resize a diskgroup on-the-fly AND rebalance our extents evenly at the same time when we add a new LUN. Even if you only start with a single LUN, you may end up with more in the long run.
    Fourth, because an ASM diskgroup is not true RAID, you are able to use it to stripe across volumes. This means that in a SAN with 3 trays, you can carve a LUN from each tray and use it to form a single ASM diskgroup. This further distributes your storage and reduces throughput bottlenecks.
    I have not seen any tried and true formula for the number of LUNs per ASM diskgroup, but you can calculate it based on your throughput per capacity. Make sure the LUNs provide maximum and equivalent I/O operations per second per gigabyte.

  • Silent install- ASM Configuration Assistant fails

    I am trying to do a silent install with response file. At the end of the install it says I need to run configToolAllCommands which I do but the ASM Configuration assistant fails. I assume I need to pass in asmsnmp password but how do I do that? I see I can specify ResponseFile=<fn> when I run configToolAllCommands but how do I set the asm passwords in a response file? I tried just creating a response file that included asmsnmpPassword=mypassword and sysAsmPassword=mypassword but it didn't like that. Anyone know how to pass in the password? I think it will set up the asmsnmp user in this configuration assistant? because that is one of my problems after the install completes I don't have that user set up. I need all of this to be automated.
    thanks for any ideas.

    well I did not find any documentation on how to create a resposne file for the ConfigToolAllCommands- all I found using the -help option was that I could include a ResponseFile=<fn> parameter. so all I did was put 2 llines in the file sysAsmPassword=mypassword and asmsnmpPassword=pAssword. And that doesn't work...

  • ASM Configuration on oracle 10.2 RAC

    hi all
    os : sun sparc solaris 10
    db : 10.2 rac database
    clusterware configured using raw devices.
    we have no other option than configuring asm on raw devices.
    could u tell me narrows steps how to do it manually as well as using dbca

    Hi
    I've do mine last week but it's in HPUX not sun and not with raw device but i think it's the same
    Steps:
    1- Launch dbca
    2- Choose configure ASm
    3- Select all the nodes
    4- Choose Create Initiialization parameter file and click on ASM parameters and in the asm_diskstring parameter specify the disk you want to use in asm group example
    vg01/vol1,vg01/vol2, ... Don't specify first the disk group
    5- Create new disk group
    6- choose the disk candidate for the group
    7- Finished

  • The ASM configuration

    dear team,
    i have been working on migrating my DB to ASM and while i was configuring ASM i got the following issues.
    1- when i have to prepair the disk i used fdisk tool to make the filesystem table and then save the configuration for each disk. "do i have to use mkfs tool after that"
    2- after that i used the command "oracleasm createdisk" to create the ASM disk but when using the DBCA to configure ASM the names of the disks i created using "oracleasm createdisk" wasn't available instead the original disk names were there. (so the question here is what is the difference between using the oracleasm createdisk and creating disk group using DBCA)
    3- for the DBCA to be able to see the disks, i have to change the permission of the disk to 666 using chmod command.. but when i restart the system, these permission just return back to the old value(NOT 666) nwhich makes it impossible to start the ASM instance.
    4-Do i have to use scsi disks for ASM or i can use IDE disks too. if yes please tell me how...
    thank u in advance.

    Overwrite the first several MB of the partition with /dev/zero.

    # dd if=/dev/zero of=/dev/rdsk/c1t3d0s7 bs=1024k count=10

  • ASM Configuration on Solaris

    Hi,
    I want to configure ASM on Solaris Oracle sparc-64 bit server with Netapp storage.
    I am bit confused, when to create diskgroup using asmca. Because there is no asmlib package available. I cannot start grid installation because during installation it asking for disk (which i want to use from shared storage diskgroup).
    Yuvraj

    You should read the installation REQUIREMENTS for the platform you are using. You do NOT need to follow some other document to "mark" the devices for ASM. It is not necessary. I have NEVER done this, nor have I EVER used asmlib on Linux. IT IS NOT NECESSARY!!!!!!! Read the Oracle docs.
    have sys admin configure devices to be visible for all nodes (stand-alone or cluster)
    Make sure you use fdisk and use a partition that excludes the first 2 cylinders (0-1). Your partitions should start at cylinder 2. If you do not, ASM will overwrite the Solaris VTOC for the device rendering it unusable until you correctly partition the devices. The device should only have 2 partitions. Partition 1 is cylinder 0-1, and Partition 2 is cylinders 2-<last>. All ASM disks in a given DISKGROUP need to be EXACTLY the same size. You can have multiple diskgroups with different size devices, but that just makes managing your devices more complicated. A word of warning, in 11gR2, if you use a diskgroup with EXTERNAL REDUNDANCY, you will only get 1 voting file. The recommendation for a CRS diskgroup is to be made up of 3 x 2G devices for OCR/VOTING with NORMAL redundancy. This will create 3 voting files.
    set correct ownership of grid:oinstall (or whatever:whatevergroup) for only partition 2 of these devices
    Next make sure the grid user and the oracle rdbms user can both READ and WRITE to these partitions (rdbms user must be a member of the oinstall/whatever group).
    during the install, make sure you change the ASM_DISKSTRING to point to these devices:
    eg: /dev/whatever*p2. The installer will then mark the devices properly and create the diskgroup(s)
    I don't know why so many people make this so hard. It is NOT that hard!!!!!

  • To reduce a miror copy from high redundancy ASM configuration to normal?

    If we have configured "high redundancy ASM disk group", then late on, wanted to change it to "normal redundancy", then it becomes 2-mirror copies.
    Can I achive that, and what steps ?
    Thanks for your inputs in advance.

    backup database (someplace other than ASM)
    shut down database
    drop diskgroup
    recreate diskgroup with normal redundancy
    restore database
    or
    create new diskgroup with normal redundancy
    migrate all datafiles to new diskgroup
    (look at RMAN backup datafilecopy and switch datafile)
    you must shut down the database in order to move the system datafile etc... Which, if the database is small enough, it may be faster to do option 1.

    After reading some more documents, I found out that you actually need to partition the harddrive. I probably will partition it using a software like magic partition. This is different than Redhat Linux 9.0 Personal.

  • SSD and ASM configurations

    Hello all,
    Although I realize that the question of configuration on ASM regarding the use of SSD storage devices is, or should be mote at this point.
    I still see, from time to time, questions and discussions on this topic in the other forms.
    I am wondering if it would be possible to create such a forum just to discuss these questions?
    But then where do you put it?
    Should this be a storage section for SSD?
    Database ASM storage or a subset or either?
    What do you think?

    No.

    If you happen to have a question dealing with a Sun/Oracle branded piece of storage hardware such as an array or a tape library, it goes here.

  • Asm configure for windows

    Hi All,
    I am using Oracle 11g with win xp as operating system.
    I have three partition for hardisk.
    c:\ is for windows and oracle and program files - Primary partition
    d:\ free space no file exists here but can see in windows explorer - logial drive partiton
    and one more partiton is there but I have made it unsed. it shows green color in computer management\disk management windows.
    so when check in windows explorer I find it had c: and d: drive only.
    I want to create oracle database with asm
    I click the DBCA and select configure automatic storage management and then
    click next
    step 2 asm diskgroup I find no groups there.
    so I click the create new button and then
    the next window says to add a disk group name
    I enter dsk1 as my disk group name
    I have to select member disk path. but there are no path I can find below.
    I tried with show all radio button but still there were no files.
    I select the stamp disk button and n window open
    I the n select add or change label and click next
    it shows windows with two paths and both of them a disable.
    I cannot select those path
    select the disk to be stamped. it shows partiton1 and partion2.
    I have loged in as admin on OS
    oracle csservice is started
    oracle asmservice is started
    Pls some one help me
    rgds
    saz

    Hi, you say that
    +"it shows windows with two paths and both of them a disable.+
    +I cannot select those path+
    +select the disk to be stamped. it shows partiton1 and partion2."+
    Disable because have formatted these drive,delete these volumes and do not format then you will see these as enable,Then you can create ASM instance and diskgroups,finally you can create database using this disk groups.
