    Cold Backup with Ex Libris Backup package fails with Oracle 19c in an all-in-one environment

    • Product: Aleph Version 
    • Product Version: 23
    • Relevant for Installation Type: Local



    The Cold Backup with the Ex Libris Backup package (Oracle 19c) in an all-in-one environment fails with error:


    By default the following option is  set up in $alephe_root/aleph_start



    if ($ORA_HOST != $Z39_HOST) then

               setenv    TWO_TASK $aleph_db

               setenv    ora_connect_mode   LISTENER



    $alephe_root/aleph_start was defined as:

    setenv    ORA_HOST          alephprod

    setenv    Z39_HOST


    Since variable ORA_HOST is not equal to Z39_HOST, the system is assumed to be working as a TWO_TASK system, i.e. dedicated Oracle Host, causing the Backup to fail.



    1. Adjust Z39_HOST to contain the same value of ORA_HOST in $alephe_root/aleph_start



    setenv    ORA_HOST          alephprod

    setenv    Z39_HOST          alephprod


    2. rerun the Cold Backup
