stty tcgetattr errors

Hi,
I have an app that runs Oracle 8.1.7 residing on a AIX 4.3 ML 10 . preiodically app sends out a status log like the one displayed below. Lately I have noticed this stty:tcgetattr message in the log. Script that writes this output calls sqlplus, gets the required count and writes output to file.
Question is what is causing this "stty: tcgetattr" message and how can i prevent it from occurring
Please let me know Thnx....

stty: tcgetattr: A specified file does not support the ioctl system call.

What usually causes a situation like this is a .profile file. People will load commands like:
stty intr ^c
or something into their .profile. And then Oracle people also put in stuff like
ORACLE_VARIABLE=something
export ORACLE_VARIABLE

Then they write a script that needs that oracle variable. So to make the script self-sufficient, they will run .profile with the dot command.

Then they run that script via cron and now there is no controlling terminal. The script runs .profile and .profile tries to run stty. Bingo.... you get that error message.

So check for that...

Thank You this is pretty cool...
profile has stty erase ^?, script inturn was running .profile.
I have removed stty erase ^? from .profile and no longer get the error. Now I will move towards trying to fix the script..

Thnx....

Well that's not a great solution. Now when the oracle user signs on, the erase character will be wrong.

I would move those environment settings into a file called .oracle_setup or something. Then put a
. ./.oracle_setup
in .profile and in any scripts that need it.

Hi,
Well thats exactly whats happening, all week i have been attending calls regarding dev and test engineers not being able to use the erase character.
I have the script below. Would appreciate if you could guide me with your valuable suggestions.

script runs in a cron every ten minutes:

#!/bin/ksh

# $Log: getStats,v $

stty errors

All well, with the . ./.oracle_setup solution.
But what if is the script is executed as follows:

su - sewiefr -c start_application.sh

The .profile is called anyway
