1. Are you installing an Oracle 12c RAC or Oracle 11g… check this, maybe it’s a typo error:

    Oracle Grid infrastructure Prerequisites

    Step 1: Verify oracle-rdbms-server-11gR2-preinstall-1.0-7.el6.x86_64 rpm on both the nodes

    [[email protected] ~]# rpm -qa | grep 11g

    • Thanks Luis. At the time oracle-rdbms-server-12cR1-preinstall was not available. It can now be downloaded and installed by typing the yum command.

      yum install oracle-rdbms-server-12cR1-preinstall

  2. Hi got the following error message due to SCAN.

    [INS-20802] Oracle Cluster Verification Utility failed

    INFO: PRVG-1101 : SCAN name “vstracdb-scan” failed to resolve
    INFO: PRVF-4657 : Name resolution setup check for “vstracdb-scan” (IP address: failed
    INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name “vstracdb-scan”

    is there any workout for this

    • Hi Rajbir,

      The message “SCAN name “vstracdb-scan” failed to resolve” suggests that the SCAN name is not registered in the DNS.

      You need to define the SCAN name in one of the two.

      1. Define a SCAN using the DNS (Domain Name Service)
      2. Define a SCAN using the Oracle Grid Naming Service (GNS)

      Look at the SCAN Document for more details.

  3. Assalamu alaikum

    You missed the cloning part and its set up. Can you please explain that ?



  4. Nice blog….i have installed oracle 12c Rac successfully following above steps.

    Thanks Natik
