I have Linux SUSE 11 SP3 with Cobol Server 2.2. When restart the server i need to change to $COBDIR/bin and execute mfds.

 

I tried launch as a service in /etc/init.d activate for level 3 and 5 of boot. It don't work.

I tried launch as a process in crontab (at reboot). It don't work.

 

Check /var/log/boot.msg

...

<notice -- Nov 17 14:17:43.782447000> mfds start
Running /etc/init.d/rc5.d/S01mfds (start)...
Done /etc/init.d/rc5.d/S01mfds
<notice -- Nov 17 14:17:44.70369000>
'mfds start' exits with status 0

...

but mfds don´t work (the port 86 web administrator show not found and the process mfds is not in the list of active process).

 

What need to start mfds automatically at reboot?

 

Please send me any suggestions.

Thanks in advance,

 

Enrique Vera.

    Probably you're missing something necessary in the environment, or starting MFDS under a non-privileged account. (MFDS needs to run as root in order to bind to port 86, which is a reserved port on UNIX/Linux systems.)

    If you provided the contents of S01mfds, we might be able to guess what the problem is.

    Well, for one thing, you're not exporting COBDIR. (PATH should already be exported, though it wouldn't hurt to export it again.) Nor are you setting LD_LIBRARY_PATH, though $COBDIR/bin/mfds is actually a shell script which exports it for you.

    I'm also wondering why you're including things like /usr/bin/X11 and /usr/games in PATH. That looks like you copied some other start/stop script rather than creating one specific to your needs.

    And you're not capturing any output from the mfds script or the mfds32 process it will eventually execute.

    And you made this an S01* script, which means it will run early in the runlevel. Possibly too early. Why are you trying to run it at that point?

    (And "Micro Focus" is two words.)

    I suggest renaming the script to something more reasonable like S95mfds, and rewriting it along these lines:

    #!/bin/bash
    # Author: your name here
    #
    # /etc/init.d/mfds
    #
    ### BEGIN INIT INFO
    # Provides: mfds
    # Required-Start: $null
    # Should-Start: $null
    # Required-Stop: $null
    # Should-Stop: $null
    # Default-Start: 3 4 5
    # Default-Stop: 3 4 5
    # Short-Description: Micro Focus Directory Services.
    # Description: MFDS for Web Services Cobol.
    ### END INIT INFO

    . /etc/rc.status
    rc_reset

    export COBDIR=/opt/microfocus/VisualCOBOL
    export PATH=$COBDIR/bin:$PATH:/bin

    # log file
    LOGDIR=/var/mfcobol/logs
    LOGFILE=$LOGDIR/S95mfds.log
    mkdir -p $LOGDIR
    echo "$(date): $1" >>| $LOGFILE

    case "$1" in
    start)
    # use colour for ease of spotting
    echo -e "\\E[36mRunning $0 (start)...\\E[0m";
    nohup $COBDIR/bin/mfds >> $LOGFILE 2>&1 &
    echo -e "\\E[36mDone $0 \\E[0m";
    ;;
    stop)
    echo -e "\\E[36mRunning $0 (stop)...\\E[0m";
    $COBDIR/bin/mfds -s 2 >> $LOGFILE 2>&1
    echo -e "\\E[36mDone $0 \\E[0m";
    ;;
    restart)
    $0 stop
    $0 start
    rc_status
    ;;
    *)
    echo "Usage $0 (start|stop|restart)"
    exit 1;
    ;;
    esac

    rc_exit
    #

    Untested, but give it a try. If it doesn't work, post the contents of /var/mfcobol/logs/S95mfds.log.

    Michael,

    My previous script is "under construction", i copied the PATH (and other environment variables) and use for trial-and-error approach because lack of documentation about this topic (launch mfds as a Linux service). The use of S01 is because initially use S95 without sucess, so change it run early for test conflict with other service.

    The good news: the script run fine, with a minor change: the line
    echo "$(date): $1" >>| $LOGFILE
    don't need the |, so the correct line is:
    echo "$(date): $1" >> $LOGFILE

    Thanks so much,

    Enrique.
