Tag: Deinstall RDBMS home

  • Deinstall Oracle Homes On Exadata Database Machine

    Overview
    After
    Oracle Platinum upgrades Oracle software for example from 11.2.0.3 to 11.2.0.4,
    the OLD Oracle Homes are not removed immediately. There are 2 different types
    of Oracle Home, Grid Infrastructure (ASM + Clusterware) home and RDBMS
    (Database software) home.
    In this article I will
    demonstrate how to De-install Oracle 11gR2 and 12cR1 Homes on Exadata database
    machine.
    Why De-install Oracle Software?
    One should consider de-installing
    Oracle software for the following reasons:
    • To save disk
      space
    • To ease
      management complexities
    • To avoid
      accidentally using unused home

    About De-install Utility
    The de-install utility works
    different for Oracle Database 11g and 12c.
    Starting with Oracle database
    11.2.0.1, Oracle recommends to use de-install utility to de-install Oracle 11.2
    software.

    You can de-install Oracle database 11gR2 software in 2
    ways:
    • External De-install
      Utility – highly recommended method
    • runInstaller

    In Oracle Database 12c, deinstall
    utility is now integrated with the Database Installation Media. You can run the
    deinstall utility using the runInstaller command on Linux and UNIX. In 12c, the
    de-install external standalone utility is replaced with a deinstall option
    using Oracle Universal Installer (OUI). The standalone or external deinstall
    utility is no longer provided as a separate installation media.
    You can de-install Oracle database 12cR1 software in 3
    ways:
    • From
      Installation Media using runInstaller (UNIX)
    • After
      Installation from ORACLE_HOME/deinstall directory
    • Using
      Parameter / Response file

    De-install utility can be used to de-install
    • Grid
      Infrastructure home (GRID_HOME)
    • Oracle Real
      Application (RAC) Database Home
    • Non-RAC
      Database Home (Single instance)
    • Grid
      Infrastructure for standalone server Homes.

    Procedure Download De-install utility for 11gR2
    • De-install
      utility can be downloaded from:

    http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
    • Accept
      license Agreement

    • Select
      latest Oracle database version based on your Operating system. 

    Here I am
    selecting Oracle Database 11.2.0.1 and Linux x86-64
    • Click
      on the “See All” hyper link to see
      all the software underneath it.
    • Accept
      License Agreement and look for the latest Oracle database version. For Example
      11.2.0.4

    Note: It is recommended to use the latest version
    of the 11.2 de-install utility. If you want to de-install 11.2.0.1, 11.2.0.2 or
    11.2.0.3 then you should use the latest version of the 11.2 de-install utility,
    which would be version 11.2.0.4.
    • Click on the
      download link to download the De-install utility for 11.2.0.4
    •  Enter the
      username and password, if prompted.
    • Download box
      will appear on your screen click OK to save the file.


    Copy De-install Utility to Exadata Compute
    Once De-install utility is
    downloaded, copy the zip to Exadata Compute node 1 and unzip it into a staging
    area. You can use WinScp or similar tool to copy the de-install utility to
    Exadata Compute node.
    Here I copied the file under “/u01/app/oracle/software” directory.

    Unzip De-install utility
    Use unzip OS command to unzip the
    de-install utility. This will create a sub-directory called “deinstall” which
    contains deinstall script.

    De-install utility Options
    The following
    are the options available with Oracle De-install utility.

    De-install DATABASE and GRID Homes
    Before running de-install:
    •  Unzip
      de-install utility into a directory outside Oracle Home.
    • No databases
      configured to use the Oracle home.

    $ srvctl config database -d <db_name>
    •  Home is not
      a configured Grid Home.

    $ ps -ef|grep d.bin
    • ASM is not
      detected in the Oracle Home.

    $ env | grep
    HOME

    Steps to De-install Oracle 11gR2 database
    software
    • After the upgrade is complete and
      the database and application have been validated and in use for some time, the
      11.2.0.2 or 11.2.0.3 database and grid homes can be removed using the deinstall
      tool. 
    • Run deinstall commands on the
      first database server. 
    • The deinstall tool will perform
      the deinstallation on all database servers. 

    Deinstall Database Home

    Here we are deinstalling Oracle
    Home:  /u01/app/oracle/product/11.2.0.2/dbhome_1/
    Replace the location with Oracle
    Home location you are deinstalling.
    Navigate to deinstall directory
    and perform a deinstall check only. The –checkonly option we will only perform
    a check without deinstalling the software.

    Post De-install Steps
    • Verify the OraInventory is update
      and OLD Oracle Homes are removed.

    orcl1@dm01db01-/u01/app/11.2.0.2/grid_1:
    dcli -g ~/dbs_group -l oracle -s “-q” “grep
    ‘/u01/app/oracle/product/11.2.0.2/dbhome_1’ /u01/app/oraInventory/ContentsXML/inventory.xml”

    orcl1@dm01db01-/u01/app/11.2.0.2/grid_1:

    /u01/app/oraInventory/ContentsXML/inventory.xml”

    • Verify the directories are deleted;
      if not manually delete them carefully.

    IMPORTANT NOTES
    • For 12.1.0.2.0, please be aware
      of the known issue with oraInst.loc discussed in “Deinstall Unable to
      Determine Product Version Number (Doc ID 1966643.1)”
    • Oracle 12c Release 1 (12.1)
      deinstall tool from Installation Media should not be used to deinstall earlier
      releases of Oracle Home as it is not supported.
    • The deinstall tool from Oracle
      Home should be used only if the Oracle Database 12.1 Software is being
      successfully Installed.
    • For Incomplete or Failed
      Software Installation, you must only use the deinstall tool from Installation
      Media.

    Conclusion
    In this article we have seen how to de-install Oracle Grid and RDBMS software. The external deinstall utility for 11gR2 and built in De-install utility makes the process easier to remove the unused or old Oracle Homes.
