    What is the process for obtaining/applying the quarterly Oracle Critical Patch Updates?


    Oracle patches are released and certified by Ex Libris twice a year.   Currently (2016), we are on a Q2 (April) / Q4 (October) schedule.
    We strongly recommend that you obtain the CPU from Ex Libris. Ex Libris customers who have an Oracle embedded license -- the majority -- are not supposed to apply the CPU directly, but to use our DB software-packing, which includes bug fixes found during the CPU testing.
    If you have an Oracle onsite license and choose to apply the CPU, we handle problems which occur on a support basis.
    This policy is described more completely in the "Ex Libris Security Patches Policy" document in the > Cross-Product > Security > Security Updates directory on the Doc Portal.


    Currently (June, 2016), the most recent updates are in the ./oracle/ directory, found on when logged in as "produser".  (The password is in the article " What login/password should be used for obtaining Oracle patches & Upgrade kits? ".)

    The 11.2 April CPU may be found at /oracle/ .


    The Cross-Product > Technical Documentation > Oracle > Oracle 11g directory on the Doc Portal have instructions for installing patch updates.  The instructions for 11g are "Oracle April 2015 Critical Patch Update for Ex Libris Products on 11.2" (found at .) 

    Note that kits are created for Oracle patches for currently-supported versions. For example, on May 20, 2012, Aleph 20 / 21 (Oracle 11) were being supported and kits were no longer being created for Aleph 19 (Oracle 10.2).


    Additional Information

    When you go to and cd /oracle/ , you see about 270 ora11.2.0.4_linux64.tar.gz_xx files. 

    You can toggle off the prompt by entering: 

    ftp> prompt 

    It will respond with "Interactive mode off." 

    Then you can do: 

    ftp> mget ora11.2.0.4_linux64.tar.gz* 

    to transfer all the files at once without needing to respond to a prompt for each.
