Re: [Wrapper-user] Wrapper-user Digest, Vol 52, Issue 4

vishal,

please have a look on the Service Controller ("sc") command available on
windows since WinNT4.

you might take a look at the "failure"-part:

DESCRIPTION:
        Changes the actions upon failure
USAGE:
        sc <server> failure [service name] <option1> <option2>...

OPTIONS:
        reset= <Length of period of no failures (in seconds)
                after which to reset the failure count to 0 (may be
INFINITE)>
                (Must be used in conjunction with actions= )
        reboot= <Message broadcast before rebooting on failure>
        command= <Command line to be run on failure>
        actions= <Failure actions and their delay time (in
milliseconds),
                  separated by / (forward slash) -- e.g.,
run/5000/reboot/800
                  Valid actions are <run|restart|reboot>  >
                  (Must be used in conjunction with the reset= option)


Hope this helps you out.

Sincerely,
Christian

Hi Leif,

Thanks for the info. This method does not work for us since it requires
manual setup. I think this is a serious limitation of the wrapper.
Unfortunately, without this fix we may not be able to use Tanuki. Do you
have an estimate of when a fix for this would be released? Can we do the
recovery settings that you mentioned by running an external command (and
need not be part of wrapper.exe)? If yes, that would work as an
temporary solution until a real fix is available, because we can script
it.

Your help will be greatly appreciated.

Regards,
-Vishal

        Vishal,
        After you have installed the Wrapper as a service, go into the
        Windows
        Service Manager and view the Properties for the Wrapper
        service.  You
        can set this up using the "Recovery" tab.
        http://mdenomy.files.wordpress.com/2008/02/configuring-recovery-2.jpg?w=500
        
        If you kill the Wrapper process, then the JVM will keep running
        for up
        to 3 times the value of the wrapper.ping.timeout property.   It
        will
        then shut itself down.   If you use the Recovery feature, I
        recommend
        setting the delay before restart to at least this long.   If you
        start
        a second JVM before the first has shut itself down then you
        would
        encounter port conflicts when the second JVM tries to start.
        You
        could handle such errors with the normal JVM restart features in
        the
        second Wrapper instance however.
        
        We are looking into what would be involved to support this
        directly
        from the Wrapper configuration file.  That would be in a future
        release however.
        
        Please let me know how this works for you.
        
        Cheers,
        Leif
