remsh?

Terry Kummell — Wed, 16 Aug 2000 14:14:36 GMT

I have two HP-UX 10.20 systems. From systema I enter the following:
remsh systemb -n doit

doit is a shell script that looks like this:
cd /a/b/c/d
domore
echo "do it done"

domore is a shell script that resides in directory /a/b/c/d and looks like this
upgm udata
echo "do more done"

upgm is a unikix cobol program that accesses data in the udata file. When
I proceed as above, I get an error.

START

Execution error : file 'udata.int'
error code: 114, pc=235, call=1, seg=0
114 Attempt to access item beyond bounds of memory (Signal 10)

HP/MF COBOL Version: B.12.25
HP-UX triserv B.10.20 E 9000/899

do more done
do it done

However, if I logon to systemb and enter doit, everything works okay! I suspect that so environment variable is to blame. To diagnose that, I inserted echo "`pwd`" commands into doit and domore. They both show directory /a/b/c/d. Any ideas?
TIA

remsh is doing the job. Try to set up the path required in your script. (path to cobol, or apps). PATH=$PATH:/whatever/you/need:/plus/more

Terry:

The problem is that remsh does not inherit the environment (which you inherit when you rlogin - ie. there is no equivalent for .profile) so you would have to set the environments... PATH as described above, as well as any SHLIB_PATH etc.

actually, you might want to rlogin to the box and type env, so that you know what variables to set.

Good luck

The issue was two environmenet variables. One for informix and the other was the PATH. I took your advice and used rlogin then env to find out what the working environmente looked like. Then, I just modified the shell script to add these variables. I was able to simplify the shell script by incorporating the domore shell script in the doit shell script. So my final shell script looks like this:

PATH=/all/sorts/of/path/stuff/plus/my/working/directory
INFORMIXDIR=/informixdir/
export PATH INFORMIXDIR
cd /a/b/c/d
upgm udata

and all is well! Thanks for the help!
