Re: [foxboro] Foxapi Applications

As a long time FoxAPI user, I can say that monitoring the processes is the
only technique that I could find.


It's pretty easy to implement in /etc/fox/user_apps.dat. The script that
processes this file won't start the next script until the current one
completes so make sure the test is the first command run.


If you put your startup stuff in /etc/fox/rc.foxapps, you can simply add the
loop to that file since it is a script.

smarter
        solution around that can be shared?
        You could just "sleep long" but I don't like that approach myself
(well not
        in a script that is), does any real programmer have any thoughts on
this
        subject?

        Of course you don't have to watch for FoxAPI in every program start
script.
        Just do it once and if FoxAPI is running all depending progs can be
        processed.
        That last remark was probably just annoying but I pressed "Send"
before I
        could remove it.

        Thanks,  

                I am doing something similar.  I was hoping that there was
some nice
        method that does not involve looping to check for Foxapi.

        Thanks Again,
        Joe

        Hi Joe.
        A solution I employ was given to me by Ron Deen via the list.  I've
modified
        it slightly to fit our installation, but it works every time.  Here
is the
        email Ron sent to me:

        *****************************
        What I did for PI:
        In the script that starts the PI client I added a test for the
presence of
        the FoxAPI progs.
        The count of 5 programs (-lt 5) includes the "grep foxapi" utility
of
        course.

        while [ `ps -ef|grep foxapi|wc -l` -lt 5 ]
        do
           echo "Foxapi not running yet"
           sleep 10
        done

        After this I run the PI start script.
        Simple but at least a bit conditional. You can make it more
intelligent of
        course...

        ****************************

        Hope it answers your question.

        I have a few Applications that use Foxapi.  What is the best way to
start
        these up when the machine is rebooted so I know Foxapi is running
before I
        start them.  Does anyone have a good solution for this?

        Joe
