You would have to have an external process tickling the tango server
to determine if down. A good tool on os x is pagesentry.
You can teach it to test certain aspects of the server, and run scripts.
Then you would have to have a script, that would run on the witango
server, that would kill the server, and start back up with the
SystemStarter command.
Don't rely on a SystemStarter restart, when witango dies, it may be
hung, and may not restart gracefully.
I do this on windows, where I first attempt to restart, after a
timeout, I kill and start.
However, this should be only needed on rare occasions, if you have to
do this alot, you have to track down stability issues.
Ultimately, with regards to stability, upgrade to 5.5, and see if
witango will let you upgrade from os x to windows.
MANY mac users have come to me for help on OS X witango systems over
the years, and I have gotten to the point, where I tell them, go to
windows.
There are too many issues on OS X witango that effect stability. And
in my opinion, most are not the fault of Witango, but OS X.
Especially as it relates to database connectivity. Witango is highly
optimized for the windows preemptive threaded environment.
I have converted 2 clients completely over to witango 5.5 windows,
and they went with skepticism at first, and now, they can't believe
the difference in speed and reliablity.
Wintel hardware is so cheap, that the hardware cost is almost a non
issue.
Something for you to think about.

Hello,
Lately our WiTango 5.0 (for OS X) witangod has been dying on us.
I'm not
really sure how to even start trying to track down why... So I'm
looking
around for info on how to do that.
In the mean time, it would be nice if there was some way to have it
automatically restarted if it dies. Is there a way to set it up to
do that,
or is there some other tool for OS X that would do it for me?
As it stands - we start it manually from the command line. I seem
to recall
trying to get it to start automatically before and having trouble
with it,
but that was probably a year and half or two years ago and I
haven't really
touched it since.
The server has pretty much been sitting unused for that time until
about 2
months ago when our old Tango 3.x server became too problematic to
continue
using. ;) So.. It's not like it's been running along fine and now is
dying.. It's only really dying now since we started acutally using
it. ;)
Any thoughts or suggestions, or whatever would be very much
appreciated.
Thanks!
- Andrew
