  • 1.  Avoid to see the Last 20 Sessions Terminated in onstat

    Posted 01/04/23 06:30 PM
    Hi,

    Recently I upgraded the informix server from 11.70FC8  to 12.10FC15 (due to compatibilty issues I don't upgrade to version 14.x)

    Since then, the output of "onstat -g ses " always shows the Last 20 Sessions Terminated

    Example:
    ...
    5 informix - 0 - 0 20480 16832 off
    4 informix - 0 - 0 20480 16832 off
    3 informix - 0 - 0 20480 16832 off
    2 informix - 0 - 0 20480 16832 off

    Last 20 Sessions Terminated
    ...
    Ses ID Username Hostname PID Time Reason
    1493833 user1 server01 28016 10/23/2022.07:00 onmode z
    1777441 user2 server02 8452 10/30/2022.07:00 onmode z
    2054425 user3 server03 16380 11/06/2022.07:00 onmode z
    ...


    I don't know why IBM changed the default behaviour of onstat -g ses

    Is there a configuration parameter or another option in onstat to avoid this part of the output ? 

    Thanks in advance,
    Roger

    Hey Roger

    The Last 20 Sessions Terminated section of the output from the onstat -g ses command was introduced at IDS 12.10 but I am not certain at which patch version ...

    As far as I know, there isn't a parameter that can be set to suppress this section of the output. Restarting the Instance will yield the desired result but that may not be feasible if your system is in Production. I haven't tested whether or not onstat -z has any effect but you may upset a few people if you wiped out the statistics gathered over the Instance uptime.

    I prefer to use what follows; Employing  sed, I search for the first occurrence of the string: Last 20 and once pattern matched I delete from that line number to the end of the piped output resulting in...
    [ informix@informix-01 ] ~ > onstat -g ses | sed '/^Last 20 /,$d'

    Thanks for your response Kirit,

    I verified that onstat -z doesn't have any effect.

    Finally, I created a little script as a "wrapper" that use "sed" according your suggest. 

    #!/bin/sh

    if [ $# -ne 1 ] ; then
    echo "Ingrese sesion"
    exit 1
    fi
    sid=$1

    onstat -g ses $sid | sed '/^Last 20 /,$d'

    exit 0

    Regards,
    Roger

    Looks good. Does it work? You may have to fully qualify the path to the onstat binary or export the PATH variable at the head of the script.

    I see those information in version 14.10.fc8 also, it's useless.
