Oracle 11gR2 RAC installation with DNS

Dear Guru's,
I want to configure RAC on two node cluster with DNS(For SCAN) in my testing server.
O.S: RHEL5.4(64 bit)
Oracle Version: 11gR2(11.2.0.2)
Note: Am creating nodes in VMware ESXi server.
Just I want to know whether DNS should be configure in any one of those NODES or in separate machine.
Bala :)

Hi Bala,
I want to configure my Database with & without DNS. (Will try both installation in different servers)I think, you have already received a link on very good article about Oracle RAC installation without DNS and DHCP (I mean Jeffrey Hunter's article).
There is one more about Oracle RAC installation with DNS and DHCP (http://gjilevski.com/2011/10/05/build-two-node-oracle-rac-11gr2-11-2-0-3-with-gns-dns-dhcp-and-haip/).
And want to know how it forwards the client connection if a node fails.. Can anyone update the URL for this..There are a lot of information about it:
- http://www.oracle.com/technetwork/database/features/oci/taf-10-133239.pdf
- http://docs.oracle.com/cd/E14072_01/java.112/e10589/apxracfan.htm
- http://www.oracle.com/technetwork/database/app-failover-oracle-database-11g-173323.pdf
Very good videos:

  • SCAN Name issue in Oracle 11gR2 RAC Installation

    Hi,
    I am trying to install Oracle 11gR2 RAC on VM ware and I got the INS-40922 (Invalid SCAN name). Do I need to create the SCAN name prior to the installation?
    I have public,private, and VIP's. I am not sure how I create this SCAN Name. Please share your thoughts
    Thanks

    During installation of grid infrastructure SCAN will be automatically created. If you are using DNS then put the scan name and scan ip addresses entries in DNS . If you are not using dns/gns then put scanname and scan ipadress hosts file on each node in the cluster. Before installation, you should not be able to ping scan ipadresses.

  • Oracle 11gR2 RAC problem with resource state

    Hi all,
    I installed Oracle 11gR2 grid infrastructure with 2 nodes and I installed DB 11gR2.
    S.O: HP-UX
    I actived both DB instance in each node.
    For an hardware problem node 1 become unstable (continuos auto reboot).
    I found that the problem was RAM.
    However I note that database resource is in a particular state and i don't able to reset it.
    Performing command crsctl status resource ora.orcl.db this is the result
    ora.orcl.db
    1 OFFLINE UNKNOWN node1 Startup Initiated
    2 ONLINE ONLINE node2 Open
    That UNKNOWN state is really abstruse.
    I tryed to perform crsctl stop resource ora.orcl.db -n node1 and the result is

    How do I do to reset that UNKNOWN state?
    Thanks in advance.
    Bye

    I tryed srvctl enable instance -d orcl -i ORCL_1
    but the results is
    srvctl enable instance command is not supported for configuration using server pool.
    I tryed to delete service ora.orcl.db and recreate it.
    Now I have

    In new project we have proposed to have 2 nodes single site RAC database Oracle 11gR2 64 Bit . We are going to have OEL 5.4 64 Bit Linux as OS and IBM as machine .
    We are migrating standalone 10g R2 database to 11r2 Rac and from HP-UX to OEL Linux . We are migrating from different datacenter .
    What would be the pfile configuration (i mean memory size doubles ) in RAC ?
    We are going to use IBM storage . Need light on followings . Pls help me out
    1>Requirements for installation
    2>Grid installation requirements
    3>ASM instance is physical database instance or just service ?
    4>Any oracle document for installation of 11gR2 Grid and RAC?
    If you provide me authorized links of RAC installation that would be better .

  • Oracle 11gR2 RAC setup with ASM option running on two nodes . Seeking help

    Hi ,
    Recently we have migrated to 11gR2 extended RAC for one of our application using ASM . Its a two node RAC setup . We are using ASM Normal redundancy feature maintaining two failure group .
    I need few clarification regarding our new DR set up .
    We are planning to have EMC SRDF replication from any of node storage ( Either 1 or 2) to the DR disks .
    Its stright to use when we use the normal file systems . In case of ASM , I am not sure how this replication will work ? and on which level the replication should happen ?
    Do i need an ASM instance up and running on DR server , Which will recognize the disks as it is once DR disks are separated from prod replication and assigned to the server ?
    What should be prerequisite on DR server before we can start the srdf replication (EMC) and make it work .
    Thanks for All your Valuble suggestion .

    Before you decide to use EMC replication give considerable thought to the fact that you are introducing a single point of failure.
    Hardware snapshot replication is very fast. That is all it is. If you database crashes because of corruption on disk ... your replica will be equally corrupt.
    What is fast can not do what DataGuard does ... verify quality. If the point is DR. Go with DataGuard unless EMC is willing to, in writing (not verbally) give you a guarantee (in hard cash) to cover all costs if they replicate bad blocks and it causes an outage.
    And just so no one thinks I'm picking o EMC ... the same weakness exists with all of the other storage vendor's products.

  • Oracle 11gR2 RAC Installation - ASM Disks - Need advice on configurations

    Hi Guys
    How many disks are needed for Voting, Data, Log and Failover. Each should be in a seperate group or it can be in a single group of disk. Please advice. Thanks.

    Hi Friend,
    Option 1 :
    If Oracle Clusterware is used for implementing normal redundancy. We require the following for failover purpose also.
    1. Two OCR files - 280 MB each
    2. Three Voting Disks - 280 MB each
    Total - 1.4 GB approx
    Option 2 :
    Oracle recommends that the disk used for the file system be on a RAID. When you use external redundancy the minimum requirement is One OCR and One Voting Disk with 280 MB each.
    Choices :
    1. External Redundancy - > Minimum No Of Disks (1) - > One OCR (280 MB) and One Voting Disk (280 MB) -> 580 MB
    2. Normal Redundancy - > Minimum No Of Disks (3) - > Two OCR (560 MB) and Three Voting Disk (840 MB) -> 1.4 GB
    3. High Redundancy - > Minimum No Of Disks (5) - > Three OCR (840 MB) and Five Voting Disk (1.4 GB) -> 2.3 GB
    So, Choose based on redundancy...
    Hope it helps..
    Note : Use ASM for storing above files..
    Thanks

  • Oracle 11gR2 RAC with Sun clsuter 3.3 clsetup not showing  ASMDiskGroup RS

    Hello,
    I am installing Oracle 11gR2 RAC on Solaris cluster 3.3 with hardware RAID and ASM
    I was able to register rac-famework-rg and crs-framework-rg.
    Oracle RAC is up and running (confirmed from crs_stat -t -v)
    However, while creating option 5. Automatic Storage Management (ASM) on clsetup, I was getting ERROR: ASM is either not installed or the installation is invalid!
    I have created the asm-inst-rg with resource asm-inst-rs and asm-dg-rg with resources asm-dg-fra, asm-dg-data and asm-dg-crs using CLI. Please find the complete clrg and clrs status output below:

    Once I reach clsetup option 6: Resources for Oracle Real Application Clusters Database Instances, I was able to select cluster db name, oracle home, SID for both nodes, and it listed the asm-inst-rg and asm-inst-rs for selection of "Specify Oracle ASM Instance Resource".
    The problem is the the next selection which is "Specify Oracle ASM Disk Group Resources" which does NOT list any asm-dg-rg or asm-dg-fra or anything, instead, it throws error "No existing disk-group resources available for selection. Run ASM subwizard create new resource(s) and come back to this panel for the selection."
    Kindly guide me to create Resources for Oracle Real Application Clusters Database Instances either in CLI or clsetup
    Thanks and Regards

    Solaris Cluster 3.3 u1 solved the issue.
    The problem right now I am facing is IPMP on the public interface.
    When I remove the cable on the bge0, the ip on bge0 and the SCAN IP's are plumbed to bge1 which is in sc_ipmp0, but NOT the virtual IP!!! and the listeners on both nodes go offiline!!!
    any inputs on the configuration will be highly appreciated..

  • Oracle 10g R2 installation with ASM+RAC

    Gurus,
    Need some suggestuon on Oracle 10g R2 installation with ASM and RAC option.
    We have found many documents on the Oracle, HP, HP-Oracle CTC and third party web sites, but nothing that is specific to this particular combination of separate
    ORACLE_HOMEs, ASM and 10g RAC CRS. It is unclear for me from the documentation how this combination of ASM and 10.2g RAC may best be installed.
    The high level steps i got after reading lot of docs as follows - but i am not sure whether these are correct or not. if they are correct, can any one share their experience/notes please?
    1) Install CRS
    2) Install RDBMS for ASM HOME - create separater oracle home for ASM instance using OUI
    3) Install RDBMS for RAC Database Home - create separater oracle home for RAC database using OUI
    4) Create ASM database using DBCA -
    5) Use dbca to create database.

    Oracle provides 'paint by numbers' tutorials called 'Oracle By Example'. (Go to OTN, check under the Training tab)
    They have one for a Windows based ASM/RAC that you might want to review. Not your specific environment, but the steps will be dag-nabbed close.
    I recommend walking the path (http://otn.oracle.com >> training:OBE >> Database 10g Release 1:VMWare:Installation

  • Oracle 11gR2 RAC VM and SCAN and DNS and /etc/hosts (two) setup questions

    Hi,
    I am looking forward to setting up two Oracle 11gR2 RAC instances
    on my Oracle VM test machine.
    I plan on using the Oracle 11gR2 RAC VM template.
    I want the final Oracle 11gR2 RAC instances to have SCAN that uses DNS.
    The DNS will be pre-installed in the JeOS.
    My first simple question about the setup is the following.
    In my DNS name file, for example,
    /var/named/chroot/var/named/milkyway.univ.db
    do I need to provide the racnode1 and racnode2 information,
    for example,
    # DNS name file (snippet)
    myjeos IN A 192.168.1.150
    racnode1 IN A 192.168.1.161
    racnode1-vip IN A 192.168.1.163
    racnode2 IN A 192.168.1.162
    racnode2-vip IN A 192.168.1.164
    rac-scan IN A 192.168.1.131
    rac-scan IN A 192.168.1.132
    rac-scan IN A 192.168.1.133
    Or, can I just provide only the rac-scan information
    # DNS name file alternate (snippet)
    myjeos IN A 192.168.1.150
    rac-scan IN A 192.168.1.131
    rac-scan IN A 192.168.1.132
    rac-scan IN A 192.168.1.133
    What I am getting at is the following.
    Within the install process, will racnode1, racnode1-vip, racnode2,
    and racnode2-vip host names and their IP address be written
    to the RAC instances /etc/hosts files? (So I should not bother
    to put them in the DNS name file like '# DNS name file alternate (snippet)'?)
    Or, should I put the racnode and racnode-vip host names and IP addresses
    in the DNS name file like '# DNS name file (snippet)'?
    The second question is the following.
    Are the cluster name and the scan name allowed to be different?
    Currently, I would plan them to be different,
    for example, rac-cluster and rac-scan.
    Or, are they required to be the same,
    for example, rac-cluster and rac-cluster.
    Thank you.

We write this data out to /etc/hosts just to reduce the amount of round-trip DNS requests the cluster nodes make for themselves.
    Are the cluster name and the scan name allowed to be different?They can be different.

  • Oracle 11gR2 RAC - R language integration

    Hello,
    We want statistical language R integration with oracle database. Does this come with default installation of oracle database Oracle 11gR2 RAC ?
    OR it requires EXADATA - BIGDATA (oracle appliance)?
    Kindly let us know steps for installation /enabling R language ? Basically we are looking for 3 options (transparency, In-database, embedded). Optimal option choice is done automatically depending on R language script (I think R script needs to have different calls?)
    Thanks

    Please do NOT duplicate your questions here.
    R is a language. Oracle is a database. You store data in a database. You write programs [using a language such as R] to extract and manipulate data from the database.

Does these options come by default or we require statistical language R integration?

    The only methods of optimization are partitioning of the data by some date or if data set is narrow (few columns)l enough, partitioned IOT.

    Folks,
    Hello. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer and according to the tutorial
    http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
    I have been installing Grid Infrastructure using runInstaller from step 1 to step 9 of 10 in both VM rac1 and rac2.
    Now, I am running the script root.sh in VM rac1 and rac2 as below:
    [root@rac1 /]# /u01/app/grid/root.sh
    Output:

    As we see the output above, rac1 and rac2 get the same problems. in addition, rac2 fails to start ASM and Clusterware stack. Thus, I have 2 questions:
    First, the common problem for rac1 and rac2 :
    1)Module "oracleoks, oracleadvm, oracleacfs" not found
    2)/dev/asm/.asm_ctl_spec not detected
    3)ADVM/ACFS installation failed
    Do the above 3 factors affect Grid and DataBase Installation later ? If yes, how to solve these problems ?
    Second, how to start ASM and Clusterware stack in rac2 ?
    Thanks.

    you have 2 options:
    1. OEL 5.6 comes with 2 kernels, the original Red Hat, and Oracle UEK, you can choose not to use UEK
    or the one i would recommend:
    2. Upgrade Grid Infrastructure,
    *11.2.0.3.1* (patch 13348650, released about a 1 month ago) supports ACFS on UEK (starting with 2.6.32.200 IIRC)
