Script question

[wvsa]

Good morning admins. Have a quick questions regarding the following script:
# begin script
PATH=/sbin:/usr/sbin:/usr/bin:/opt/omni/lbin:/opt/omni/bin
export PATH

if [ $SMEXIT != 0 ]
then
/opt/omni/lbin/backuperr

exit 0

else
echo "Successful Backup"
echo "Now submitting Daily_PROD_2_ULT backup run."
omnib -datalist Daily_PROD_2_ULT -no_monitor
touch /tmp/daily_prod_2_ult
echo `date` >> /tmp/daily_prod_2_ult
fi

echo "${progname} completed!"

exit 0

Would like to have the omnidb process complete before the file is touched, in effect have the script suspend until the Omniback backup is complete, once the backup is complete then have the file created. THankyou in advance for input.

omnib surely starts backup in background.
you should use wait to be sure omnib is finished.

Try to look how this can be merged in your script (might be better with awk, but...)

#!/bin/sh

nohup sleep 5 >/dev/null 2>&1 &
SleepPID=`ps -edf | grep "sleep 5" | \
grep -v grep | tr "[:blank:]" " " | \
sed "s/ */ /" | cut -d " " -f 3`
wait $SleepPID
echo I waited for sleep to finish

Hi,

# begin script
PATH=/sbin:/usr/sbin:/usr/bin:/opt/omni/lbin:/opt/omni/bin
export PATH

if [ $SMEXIT != 0 ]
then
/opt/omni/lbin/backuperr

exit 0

else
echo "Successful Backup"
echo "Now submitting Daily_PROD_2_ULT backup run."
omnib -datalist Daily_PROD_2_ULT -no_monitor
wait
touch /tmp/daily_prod_2_ult
echo `date` >> /tmp/daily_prod_2_ult
fi

echo "${progname} completed!"

exit 0

I am not sure if this will work - but try it out.

Hi,

You can remove the no_moitor option and check for RC and if you get a RC=0 then touch the file, else exit.

omnib -datalist Daily_PROD_2_ULT
if [ $rc = 0 ]
then
touch /tmp/daily_prod_2_ult
else
fi

Hope this helps.

Hi,
The correct solution is to run
touch /tmp/daily_prod_2_ult

as a post_exec script in the

Daily_PROD_2_ULT

datalist

[RAC_1]

Change following code
else
echo "Successful Backup"
echo "Now submitting Daily_PROD_2_ULT backup run."
omnib -datalist Daily_PROD_2_ULT -no_monitor
touch /tmp/daily_prod_2_ult
echo `date` >> /tmp/daily_prod_2_ult
fi

TO

else
echo "Successful Backup"
echo "Now submitting Daily_PROD_2_ULT backup run."
omnib -datalist Daily_PROD_2_ULT -no_monitor && touch /tmp/daily_prod_2_ult
echo `date` >> /tmp/daily_prod_2_ult
fi

(See the use of &&)

Sorry,
I noticed that your script is a post_exec script (the SMEXIT variable) and you want to start a another backup from that script (consecutive backup).

You could use a post_exec script for the second backup which do the:
if [ $SMEXIT = 0 ]
then
touch /tmp/daily_prod_2_ult
echo `date` >> /tmp/daily_prod_2_ult

echo "${progname} completed!"
else

........

fi


Or you can use the same post_exec script for both jobs and use the variable
DATALIST
to chech which of the two jobs is runnnin and what should be done.

[wvsa]

RAC, what does the && do? Could you provide a brief explanation? Thankyou!!

"Execute upon successful completion of the previous task", as against || which is "Execute upon un-successful completion of previous task".

If the previous task is backgrounding off however, then it won't be much help, as the return is still immediate.
