Try to use SERVICES.NET.SYS and inetd:

out of MPE/iX 5.5 documentation:
The services file

The services file associates an official service name and alias with the
port number and protocol that a service uses.  You will edit the services
file for each new service that you want to add to your system.  The
remaining chapters in this book, which describe the configuration of
individual services, will assume that you know the information below.
And, of course, you can refer back to this section as needed.

If your service can configured in this way it should work, having the
background job
JINETD running all day long.

Andreas,
Thank you for your mail.
Here some more details:
The operating system:
HP3000  Release: C.55.00   User Version: C.55.00   THU, OCT 15, 1998,
8:25 AM
MPE/iX  HP31900 C.05.08  Copyright Hewlett-Packard 1987.  All rights
reserved.
I have a job that launches a perl script in the POSIX environment. This
job
communicates through pipes to an executable. In some cases, it depends
on
the server load and user input the pipes are broken and the job ends
abnormaly. The question is how to restart the job automatically and is
there
a possibility to do this with a built-in operating system feature.
As it exists for example on Unix systems: You can setup a service (the
job)
as a respawned permanent job. The operating system keeps track if the
appropriate process id does still exist and if not it automatically
restarts
the job.
Thank you for your assistance
Regards
Raymond Roesch

could you please give more details ? I'm not so firm in Unix that
respawn
and disappear will ring a bell in my MPE brain ...
Thanks, Andreas Schmidt, CSC, Germany
