    • Product: Aleph
    • Product Version: 20, 21, 22, 23
    • Relevant for Installation Type: Dedicated-Direct, Direct, Local, Total Care

     

    Description

    1) Job daemon process jobd is not always killed from the aleph_shutdown and may run twice after aleph_startup 

    2) UTIL C 1 may display strange processes: 
    *** util_c_01 - check ABC01 batch queue *** 
    19430 pts/0 S+ 0:00 grep -E /exlibris/aleph/a22_1/tmp/ABC01 | ABC01 
    Enter to continue

     

    The problem is caused by a change in grep-command in a recent Red Hat 6 update. 
    Customers using other OS (as Sun Solaris or CentOS) or older Red Hat versions are not affected. 

    Ex Libris will provide fixes in upcoming Aleph 21 and 22 Service Packs: 

    #2644 (SP 21.1.10) (scheduled for Dec 6, 2015) (scheduled for Jan 31, 2016) 
    #2242 (SP 22.1.4) (scheduled for Dec 6, 2015) 

    Until the SPs are released, affected customers can implement the workaround.

    Workaround

    Important: 
    Only customers running Aleph 21 or 22 on Red Hat 6 should implement the workaround. It is not relevant for Sun Solaris customers or customers using other Red Hat versions. 

    To implement the workaround: 

    1) Make a copy of the current version of your aleph_ps-script in $aleph_proc-directory (e.g. /exlibris/aleph/a22_2/aleph/proc): 
    >cp aleph_ps aleph_ps.save 

    2) Download the file aleph_ps.gz to $aleph_proc-directory on your Aleph server. 

    3) Unzip the file: 
    >gunzip aleph_ps.gz
