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.

  • Reinstalling Oracle 11gR2 RAC Grid Problem - ASM Disks Group

    Folks,
    Hello.
    I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer.
    I have been installing Grid Infrastructure using runInstaller in the first VM rac1 from step 1 to step 9 of 10.
    On the step 9 of 10 in the Wizard, accidentally, I touch the Mouse, and the Wizard is gone.
    The directory for installing Grid in the 2 VMs is the same: /u01
    In order to make sure everything is correct, I delete entire directory /u01 in the 2 VMs and install Grid in rac1 again.
    I have understood it's not the right way to delete /u01. The right way is to follow the tutorial
    http://docs.oracle.com/cd/E11882_01/install.112/e22489/rem_orcl.htm#CBHEFHAC
    But I have deleted /u01 and need to fix one by one. I install Grid again and get the error message on step 5 of 9 as follows:
    [INS - 30516] Please specify unique disk groups.
    [INS-3050] Empty ASM disk group.
    Cause - Installer has detected the disk group name provided already exists on the system.
    Action - Specify different disk group.
    In Wizard, the previous Disk Group name is "DATA" and its Candidate disks (5 ASMDISKs) are gone. I try to use a different name "DATA2", but no ASMDISKs come up under "Candidate disks". For "ALL Disks", all ASMDISKs cannot be selected.
    I want to use the same ASM disk group "DATA" and don't want to create a new disk group.
    My question is:
    How to have the previous ASM disks and its group "DATA" come up under "Candidate Disks" so that can use it again ?
    Thanks.

    Hi, in case this helps anyone else. I got this INS-30516 error too was stumped for little while. I have 2 x 2-node RAC which are hitting same SAN. The first-built RAC has a DATA diskgroup. When went to build second RAC on new ASM disk new DIskgroup (but same diskgroup name DATA) got INS-30516 about diskgroup name already in use etc. Finally figured out all that was required was to restrict diskstring using button in installer to only retrieve the LUNS for this RAC (this was quick and dirty - all LUNS for both RAC being presented to both RAC). Once diskstring only searched for the LUNS required for this RAC only, e.g.
    ORCL:DATA_P* (for DATA_PD and FRA_PD)
    the error went away.
    I also have DATA_DR and FRA_DR presenting to both RAC. Apparently it scans the header and if it finds a diskgroup name that is already in use based on the diskstring scan it will not allow reuse of the diskgroup name since it has no way of knowing that the other ASM disks are for a different RAC.

    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:
    [[email protected] /]# /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)

  • Oracle 11gR2 RAC: how to solve "user profile creation mask failed" ?

    Folks,
    Hello.
    I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer.
    I am using Cluster Verification Utility (CVU) to test the 2 nodes for Grid installation as follows:
    [[email protected] grid] $ ./runcluvfy.sh stage -pre crsinst -n all -r 11gR2 -orainv ora11g -fixup -fixupdir /mydir -verbose
    All items for rac2 are passed. There is only one item for rac1 is not passed as follows:
    Check default user profile creation mask:
    Node Name: rac1
    Available: 0002
    Required: 0022
    Comment: failed
    There are 3 ways to solve this issue:
    1) In the file /etc/bashrc, change the line "umask 0002" to "umask 0022".
    2) In the file /etc/profile, add line "umask 0022" at the end of the file.
    3) In the file /etc/csh.cshrc, change the line "umask 002" to "umask 0022".
    In rac2, I got the same issue in the past. I just change the line "umask 0002" to "umask 0022" in the file /etc/bashrc and the issue is solved.
    But in rac1, I have tried each of the 3 options and also combined 1) and 2), 1) and 3), 2) and 3), 1) and 2) and 3). Totally, that's 7 options. But all of 7 options cannot solve the issue.
    The script runcluvfy.sh still tests rac1 user profile creation mask failed. My question is:
    Do any folk understand how to solve VM rac1 user profile creation mask problem ?
    Thanks.

    Folks,
    Hello. I follow the document "Oracle Grid Infrastructure Installation Guide 11g Release 2 (11.2) for Linux E22489-04" and do the following:

    Output: /bin/bash
    This means we need to edit Bash shell file .bash_profile.
    [[email protected] ~]$vi /home/ora11g/.bash_profile
    Add this line: umask 022
    Then I save the file .bash_profile and reboot OS.
    Then I run the following command:

  • Installing Oracle 11gR2 RAC Problem: ASM disks

    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
    At the first time, I create VM rac1. While its OS Oracle Linux 5.6 is booting, initializing ASMLib Driver OK. I create 5 ASM disks successfully using the command:
    [[email protected] /]# /etc/init.d/oracleasm createdisk ASMDISK1 /dev/sdb1
    Output: Marking disk "ASMDISK1" as an ASM disk: OK
    Because the hard disk space of rac1 is not enough to install Database, I create VM rac1 again with bigger hard disk space (30GB). I do everything the same with that at the first time. But this time, While OS Oracle Linux 5.6 is booting, initializing ASMLib Driver failed. I create 5 ASM disks using the same command:
    [[email protected] /]# /etc/init.d/oracleasm createdisk ASMDISK1 /dev/sdb1
    Output: Marking disk "ASMDISK1" as an ASM disk: failed
    But when I use the command:
    [[email protected] /]# /etc/init.d/oracleasm listdisks
    Output: ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5
    My questions are:
    First, can the 5 disks "ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5" be used correctly in spite of Marking disk "ASMDISK1(2 3 4 5)" as an ASM disk failed ?
    Second, how to fix OS Oracle Linux 5.6 so that initializing ASMLib Driver OK while booting ?
    Thanks.

    Folks,
    Hello. The issue is solved by myself. Thanks.

  • Install Oracle 11gR2 RAC : Cannot remove directory bootstrap under /tmp

    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 am installing Grid infrastructure. I am on step 7 of 10 (verify Grid installation enviroment) and get this error:
    "Free Space: Rac2: /tmp
    Cause: Could not determine mount point for location specified.
    Action: Ensure location specified is available.
    Expected value: n/a
    Actual value: n/a "
    In order to fix the above error, I run "cluster verification utility" according to
    http://docs.oracle.com/cd/E14072_01/rac.112/e10717/cvu.htm I run the following command:
    [[email protected] \]$ /home_grid/runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose
    Output:
    /bin/rm: cannot remove directory '/tmp/bootstrap': Operation not permitted
    ./runcluvfy.sh:line 99:/tmp/bootstrap/ouibootstrap.log: permission denied
    From the above output, we can see the directory bootstrap under /tmp causes the problem. The solution is to remove the directory bootstrap. I run the 2 commands:
    [[email protected] tmp]$ rmdir bootstrap
    Output: Operation not permitted
    [[email protected] tmp]$ rm -rf bootstrap
    Output: cannot remove bootstrap: Operation not permitted.
    [[email protected] tmp]$ ls
    Output: there is no 'bootstrap' directory.
    My questions are:
    First, does "cannot remove boostrap in rac1" cause that /tmp in rac2 could not be determine mount point ?
    Second, can any folk help to remove the directory bootstrap under /tmp ?
    Thanks.

    Folks,
    Hello. Thanks a lot for replying. I have just run the 2 commands:
    [[email protected] \]# chown -R ora11g:dba /u01
    [[email protected] \]# chmod -R 775 /u01
    ora11g is the user who installs the Grid and /u01 is the directory where Grid is installed and dba is the group.
    I go back to Grid Installer Step 7 of 10 in rac1 and check again and see as below:
    Free Space: Rac2 : /tmp
    Cause: Could not determine mount point for location specified.
    Action: Ensure location specified is available
    Expected Value: n/a
    Actual Value: n/a
    The problem is not solved after run the above 2 commands in rac2.
    In addition, I have run Cluster Verification Utility using the command:
    [[email protected] grid]./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -r 11gR2 -orainv ora11g -verbose
    Output: All of items for rac2 are passed. There is only one item for rac1 is failed as below:
    Check default user file creation mask:
    NodeName: rac1
    Available: 0002
    Required: 0022
    Comment: failed
    As we see above, the result of CVU command is not the same with Grid Installer step 7 of 10 (Installation Environment Verification):
    CVU command doesn't find /tmp mount point problem for rac2 that Grid Installer does.
    Grid Installer step 7 of 10 doesn't find user file creation mask problem for rac1 that CVU command does.
    I have tried to find out whether creation mask failed for rac1 causes /tmp problem for rac2. I have changed the line "umask 002" to "umask 0022" for rac1 in each of the 3 files below and run CVU command each time for each file:
    rac1:
    /etc/bashrc
    /etc/profile
    /etc/csh.cshrc
    But chang the line "umask 002" to "umask 0022" for rac1 in each of the above 3 files does not solve the problem.
    My questions are:
    First, why is the result of CVU command not the same with that of Grid Installer step 7 of 10 ?
    Second, why change the line "umask 002" to "umask 0022" in 3 files can't solve creation mask problem for rac1 ?
    Third, how to solve /tmp problem for rac2 and creation mask problem for rac1 ?
    Thanks.

  • 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.

  • 11gr2 Rac Install: Stuck at the DNS SCAN portion.

    Hi Guys, it's Xev.
    Ok, I have followed his install guide to the dot. http://www.oracle-base.com/articles/11g/oracle-db-11gr2-rac-installation-on-oel5-using-virtualbox.php#install_grid_infrastructure
    During the Grid Infrastructure install portion, it's stops me and tells me that "No Locally adapter is defined" when I am right here, it won't let me past this point right below...
    http://www.oracle-base.com/articles/11g/images/ol5-112-rac/47-grid-ssh-connectivity.jpg
    Now, this install document, tells you to put the 3 SCAN Ip addresses in the /ect/hosts file and does not tell you that you need to install DNS on a server and configure it, or does he? The way he says it to
    me just doesn't make sense.
    My question is to only people that have actually installed 11gr2 RAC using VirtualBox and using oracle linux 5.8.
    He says in the install document this right here, but some how i think he is just flat out wrong.
    I quote from the install document,,,
    If you are not using DNS, the "/etc/hosts" file must contain the following information.
    127.0.0.1 localhost.localdomain localhost
    # Public
    192.168.0.101 ol5-112-rac1.localdomain ol5-112-rac1
    192.168.0.102 ol5-112-rac2.localdomain ol5-112-rac2
    # Private
    192.168.1.101 ol5-112-rac1-priv.localdomain ol5-112-rac1-priv
    192.168.1.102 ol5-112-rac2-priv.localdomain ol5-112-rac2-priv
    # Virtual
    192.168.0.103 ol5-112-rac1-vip.localdomain ol5-112-rac1-vip
    192.168.0.104 ol5-112-rac2-vip.localdomain ol5-112-rac2-vip
    # SCAN
    192.168.0.105 ol5-112-scan.localdomain ol5-112-scan
    192.168.0.106 ol5-112-scan.localdomain ol5-112-scan
    192.168.0.107 ol5-112-scan.localdomain ol5-112-scan
    Note. The SCAN address should not really be defined in the hosts file. Instead is should be defined on the DNS to round-robin between 3 addresses on the same subnet as the public IPs. For this installation, we will compromise and use the hosts file. This is not possible if you are using 11.2.0.2 onward.
    If you are using DNS, then only the first line needs to be present in the "/etc/hosts" file. The other entries are defined in the DNS, as described here. Having said that, I typically include all but the SCAN addresses..
    END QUOTE.
    So, Guys, what does he actually mean with this? MY Grid install fails when it's trying to resolved the scan. DO I need to install DNS like he gives in the link above, OR can the install work with the SCAN in the /ect/hosts file? I Personally think this is just wrong, and you have to have DNS working 3 ip round-robin for the SCAN to work.
    Please only reply to this thread if you have actually successfully installled 11rg2 Rac (11.0.1) on Oracle Linux 5.8 using VirtualBox, or actually know where i am going wrong by your own experience, not just goggle searching.....but you got it to work....
    I am begging on my knees for help with this, since I have been at this for weeks now.
    If you help me through this, I'll be your friend
    Xev.

    Hi Shivendra,

  • 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:
    [email protected] # clrg status

    rac2 Online Online - Mounted: DATA
    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..
    Thanks and Regards

  • Oracle 11gR2 RAC in LDOM Network issue

    Hi, Requesting your expert advise regarding this configuration.
    We are implementing LDOM 2.2 on two SPARC T4-4 for Oracle 11gR2 RAC; Solaris 10 U10 on both control and guest domain. The setup for each primary/control domain is: Two 10g links aggregated and have four VLAN trunked on the aggregate. vSwitch created using the aggr as the device as following per T4-4:
    NOTE: VLAN 1501 is for data connection and VLAN 10 is for heartbeat for one RAC cluster and VL 1601 and 11 is for another RAC. all together four LDOMS.

    Yes, I can connect to the vswitch interface on the control domain. I didn't specify any PVID because my understanding is that PVID will tag any frame with the PVID VLAN by default. basically the PVID for this interface is 1.
    Here's the VNET config for the other LDOM in the RAC cluster:

  • 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.

  • Oracle 11gR2 RAC - timeseries

    Hello,
    We would like to know if Oracle 11gR2 RAC supports timeseries data storage and time-series functions. Timeseries storage is quite different - in terms of storage optimization - block storages, compressions, columnar databases and others. Time-series functions like regressions, data-mining. Does these options come by default or we require statistical language R integration?
    Thanks

    1. Usally time-series data goes in multiple millions, so timeseries databases like FAME,KDB,SYBASE-IQ are used. Does oracle11gr2 provide storage optmizations, compressions, columnar database like FAME,KDB,SYBASE-IQ?

    Link is about R statistical language and data mining integration with Oracle database 11gR2. Does this come default during installation or with BigData - EXADATA? OR this is a seperate license?I am not sure about the licensing, you will need to ask your sales person, but it looks like it might be apart of ODM (oracle data mining - a licensed product)
    Take a read through this case study.
