    Oracle Inventory Directory

    Documents(rac 2 day) says the oraInventory directory is created by OUI during installation. But based on what I remember, we need to create this directory beore run OUI. So need to test. ???????????????

    1. Run the following command to check for an existing Oracle Inventory directory:
    # more /etc/oraInst.loc
    2. If the oraInst.loc file exists, then the output from this command is similar to the following:

    inventory_loc=/u01/app/oraInventory
    inst_group=oinstall
    In the previous output example:
    ■ The inventory_loc group shows the location of the Oracle Inventory.
    ■ The inst_group parameter shows the name of the Oracle Inventory group(in this example, oinstall).

    If the Oracle Inventory directory does not exist, then you do not have to create one before installing the Oracle software. ?????????????????????

    Oracle Grid Infrastructure Home Directory

    OUI installs Oracle Clusterware and Oracle ASM into a directory referred to as Grid_home.

    To create the Grid home directory as the root user, enter the following commands:
    # mkdir -p /u01/app/11.2.0/grid
    # chown -R oracle:oinstall /u01/app/11.2.0/grid

     

     Oracle Base Directory

    Oracle Universal Installer (OUI) creates the Oracle base directory for you in the location you specify.   ???????????

    1. Log in as the root user.
    2. Use the mkdir command to create the path to the Oracle base directory.
    # mkdir -p /u01/app/oracle/
    3. Change the ownership of the Oracle base path to the Oracle software owner,
    oracle.
    # chown -R oracle:oinstall /u01/app/oracle/
    4. Change the permissions on the Oracle base directory to 775.
    # chmod -R 775 /u01/app/oracle/

    Oracle Home Directory

    The document says "You do not have to create these directories before installation. By default, the installer suggests a subdirectory of the Oracle basdirectory for the Oracle home." ????????????????

    ASM

    If you
    select a noninteractive installation mode, then by default it creates one disk group
    and stores the OCR and voting disk files there. If you want to have any other disk
    groups for use in a subsequent database install, then you can choose interactive
    mode, or run ASMCA (or a command line tool) to create the appropriate disk
    groups before starting the database install.
