I am able to execute my script fine at the command prompt (i.e. ./ScriptName.ksh. But, it fails when I run it in the background using nohup (i.e. nohup ./ScriptName &

It outputs:   [1] + Stopped (SIGTTOU)        nohup ./ScriptName.ksh &

The nohup.out file logs: stty: setattr: There is an input or output error.

Any ideas what is causing this?

What program are you trying to execute?

Seems it's attempting to set tty attributes or do things like cursor positioning which is not supported in the background (i.e. without an associated tty).

The "smit" menus resp. the underlying binaries (starting with "sm_...") do such things.
Are you trying to outsmart our friend smitty?

Perhaps your script has (is executing) a terminal command like "stty"?
:p

Ooops, just saw woolmilkporc's answer...

I guess it has to do with "imp".

Just for testing: Comment out the "$RUNS 2>&1" line. Does the rest work now?

I hope you didn't post a "real" password??

Commented out the $RUNS 2>&1 line and still doesn't work. Same error.

I copied the whole script to one of my  AIXes and ran it there, without the "$RUNS 2>&1" line, because I obviously can't do an ORACLE import without making lots of modifications to your script.

Sad to say, it worked - in background as well as in foreground. I got the email (added my address, of course), containing:

(my hostname)  Wed Mar 28 00:06:29 DFT 2012-- Oracle Process on edwdev :
        COMPLETED NORMALLY.

and got a "nohup.out" file containing:

imp c25540/********@edwdev PARFILE=/data/edwtempitar_export/import.par
Ended at Wed Mar 28 00:06:29 DFT 2012

(I obfuscated your password).


Did you really post the whole, unmodified thing?

Did you remove the existing "nohup.out" file, or are you perhaps looking at old output?  The shell will append to this file instead of overwriting it!
