Hello,
My company uses a CAD programm runing on NT 4. This program was running
previously on UNIX et we made
many periodical tasks with cron. This program runs now in CYGWIN
environment and everything works fine
in Bash.
However, I tried these days to run this Programm in terminal mode with
CYGWIN cron and it did not work. The CAD program
is actually made of several modules (several little programs)
cummunicating with a file created in a working directory.
I made many tests to compare cron with planning service NT regarding to
my Bash script. My test are done with the local user
Administrator of PC NT 4. Here are the tests made :
1) The Bash script is run under Bash and creates a log file from CAD
program : IT WORKS
2) The Bash script is run under Bash but Bash is run first with a bat
File from service Planning : IT WORKS
3) The Bash script is run as a task with CRON under CYGWIN : IT DOES NOT
WORK, first module does not work
4) The Bash script was modified, I added theses two lines :
export USERDOMAIN=AUTORITE NT
export USERNAME=SYSTEM
The first module works but as soon as the second module is runned,
the CAD program stopped with errors
5) I noted same troubles when running the program with rlogin or rsh
with CYGWIN. First module is running but the second one
not. The error message of CAD program point out problem with
communication file (unable to open in READ mode).
What is the difference between CYGWIN cron and Planning regarding to NT
privileges of users. With Planning, it is the user SYSTEM
who runs CYGWIN environment but with cron it is the user Administrator.
Is there en explanation to my problem ???
