Oracle 11g Hot patching

Online Patching : you can apply or roll back online patches while the RDBMS instance is running

1) download an interim patch for 11g, f.ex. dummy patch 6198642
2) unzip p6198642_111060_LINUX.zip
3) cd 6198642
4) $ORACLE_HOME/OPatch/opatch apply -silent -connectString LSC08 -runSql

The local system has been patched and can be restarted.

OPatch succeeded.

OPatch did run the necessary script (catcpu for Dummy2007) on the various instances (LSC08). It needed only one step and 34 seconds on my notebook. This patch is a dummy patch, let’s wait for CPU January to see if it is online applicable ;-)

  1. Please shutdown Oracle instances running out of this ORACLE_HOME on the local system?

    Lets wait..

  2. I was curious about the ho tpatching as well. I looked on Metaink and found serveral patches for 11g. I looked at all the README files and they say ” Please shutdown Oracle instances running out of this ORACLE_HOME on the local system”.

    At OOW I was told that 95% of opatches can be applied hot, are these ALL in the 5%? :)

  3. I have tried a few…

    ApplySession applying interim patch ‘6353873’ to OH ‘/u021/app/oracle/product/11.1.0.6-db’

    Running prerequisite checks…

    (Oracle Home = ‘/u021/app/oracle/product/11.1.0.6-db’)

  4. Thanks for the post…this didn’t work for me, for some reason…I even tried patching opatch to a more recent release. All the locations are correct (however unorthodox) including oraInst.loc entry, etc…in your tests, have you run into this particular pre-requisite failure? Thanks!

    Running prerequisite checks…
    Prerequisite check “CheckActiveFilesAndExecutables” failed.
    The details are:

    Following executables are active :

    /u03/app/oracle/product/db/11.1.0.6/bin/tnslsnr

    System intact, OPatch will not attempt to restore the system

    OPatch failed with error code 74

  5. But I couldn’t find the p6198642 for Windows 32bit anywhere on Oracle’s Metalink site.

  6. Let me rephrade that, when I tried OPatch with the latest patch on windows, it says the OPatch file is not recognized as an internal or external command, operable or batch file. Am I right to assume that the opatch file is not compatible with windows? Please advise. Thanks.

  7. I figured out the the problem. In my case, I’m patching Oracle v11.1.0.6.0 with patch 6 (#7210195) on a Windows 2003 Server. Here’s what I did:
    1. Shutdown the Instance and all it’s services (backup first). You have to go to manage>services> and manually turn off all Oracle related services and the Distributed Transaction Coordinator (which is not of Oracle)
    2. Replace the contants in OPatch dir with the updated one from Oracle #6880880
    3. Set ORACLE_HOME path to your Oracle Home Directory to something like x:app…product11.1.0db_1
    4. Download and unzip patch 7210195 to x drive same drive as your oracle home
    5. go to the 7210195 folder and run OPatch apply
    6. reboot when patch complete

    I may have skipped some minor step here and there but that’s the basic

    …. now back to playing my xbox :)

  8. “There are no hot patches (yet)”.
    That is my proposition.

    There are no technical details available for hot patching, only pre-11g launch marketing materials.

    If there is a counterexample, except the dummy patch, for Oracle database, I will stand corrected.

  9. Hi,
    I have also tried hotpatching with dbconsole in windows but it failed,
    not sure when these kind of patches will be available.for minor one-off patches it may be available in future,i hope:)
