Re: How do I kill a hung process on Informix ODS
I think the only thing you missed is the warning that a kill -9 on a
process in a critical section can crash your engine. Dave Kosenko did a
very nice write up years back on safely killing an Online process - should
be in the archives. I think it was called 'The killing of sqlturbo' or
somesuch.

} Easy, easy guys. The " kill -9 pid " is too ugly for Informix's process
}in critical section.
}And for the first time we must to log on the remote site. The easiest way
}is to use the "telnet" utility. Issue something like this:
} telnet remote_server_name
} If you are trusted on the remote server you can spawn a remote shell :
} rsh remote_server_name
}After you log on the remote server define the pid of a hanging process and
}issue command
} onmode -z pid
}Don't use this command three times one after another ( gives the same
}effect as "kill -9" ).
}There are also some soft "kill" options like "kill -15 pid " (see man
}kill) which don't kill a process without warning.
}You can also shutdown the Informix ODS using the onmonitor utility as last
}chance.
}
} Good luck,
} Taras.
