The Process Watchdog for OS/2 Servers is available now!
Introduction
------------
We're running a few internal and external servers in our office and many of
them are accessible through the Internet. There are all kinds of services
running on them (HTTP, FTP, SMTP, POP3 etc). Everything worked (almost)
pretty well. I just had one little problem: From time to time, the SMTP
server which processes incoming mail closed without any notification. This
happened about once a week and we never found out the problem because we
couldn't reproduce the problem. No logs, no messages, NOTHING. The main
problem was that this was an unattended server and nobody took notice of the
failing service. If this happened on friday night, the server remained
inactive until monday morning. I had to find a solution...
Description
-----------
This software uses the information of the OS/2 PSTAT utility to determine
whether a certain program is still active or not. If the watchdog detects a
program which isn't active anymore, it will be restarted automatically. I
decided not to write a PM program because this utility must be as small and
slim as possible.
What you need
-------------
You need Warp V3 or Warp V4. Be sure to have the system utilities installed
because this software needs the OS/2 PSTAT command.
Configuration File
------------------
The Process Watchdog (PROCWD) needs a PROCWD.CFG configuration file. This
file contains all names of processes to be watched. Refer to the software
documentation on how to create your own configuration file.
