Omnibacks's uma utility

[Marco V. Corrales]

I can't use Omnibacks's uma utility from cron
Someone know why ?
I'm trying to invoce uma from cron to move a tape from a slot to a drive in a DLT.

Sure, because /opt/omni/lbin is not in the PATH when cron runs. Cron's PATH is intentionally sparse. You will need to set and export PATH within your script before your call to uma.

Thanks, but I'm invoking de uma with the absolute path: /opt/omni/lbin/uma

What errors do you get with uma from cron?

Thanks.
Prashant.

You also need to specify the undocumented option -tty to tell uma that this is a non-tty based session. You didn't indicate what OS and OB2 version you are running but there is a patch for this bug.

Hi Marco:

Just I as test I ran the following script to do a "stat" and send the result to a temp file under cron; it worked like a champ.

#!/usr/bin/sh

TDIR=${TMPDIR:-/var/tmp}
PID=$$
C1=${TDIR}/C${PID}_1.cmd
T1=${TDIR}/C${PID}_1.txt

ROBOT=/dev/robot/c2t3d0
D1=/dev/rmt/1mnb
D2=/dev/rmt/3mnb



echo "stat" > ${C1}
/opt/omni/lbin/uma -ioctl ${ROBOT} -tty -barcode -device ${D1} ${D2} < ${C1} > ${T1} 2>&1
STAT=$?
rm -f ${C1}
exit ${STAT}

Thank you very much.
