    • Article Type: General
    • Product: Aleph
    • Product Version: 20

    Problem Symptoms:
    * "Cannot read reply" in GUI with this message in pc_server.log:
    Empty table /tmp/utf_files/exlibris/aleph/u20_1/alephe/tab/tab_version

    * Course Reading module is unavailable and error ?€žError parsing find request" when performing searches in XXX30-library

    Cause:
    Some Aleph processes were started by root user instead of aleph user.

    Resolution:
    1. Check if (apart from apache) any active Aleph process is still belonging to root user:

    Example:
    >ps -eaf | grep root | grep aleph
    root 4129 1 0 Sep20 ? 00:00:13 /exlibris/aleph/a20_1/product/local/apache/bin/httpd -d /exlibris/aleph/u20_1/alephe/apache
    root 11080 1 0 Oct03 ? 00:01:17 /exlibris/aleph/a20_1/aleph/exe/rts32 ue_11_a xxx00.a20_1

    In this case ue_11 is belonging to root user.

    2. As root user shutdown the Aleph processes belonging to root

    3. As aleph user perform aleph_shutdown

    4. Check if any files under utf_files-directory are belonging to root user:
    > cd $aleph_utf
    > pwd
    /tmp
    > find . -user root -print
    ./utf_files/exlibris/aleph/u20_1/xxx10/tab/tab_z105_filter
    ./utf_files/exlibris/aleph/u20_1/alephe/tab/tab_io_remote
    ./utf_files/exlibris/aleph/u20_1/xxx30
    ./utf_files/exlibris/aleph/u20_1/xxx30/tab
    ./utf_files/exlibris/aleph/u20_1/xxx30/tab/tab_publish

    5. As root user delete all files and directories under /tmp/utf_files
    6. Restart all Aleph processes as aleph user (aleph_startup)
