script with symcli command not work in cron

Camel_1 — Sun, 30 Nov 2003 18:44:05 GMT

Hi there,

I have a script with the following lines:

#!/usr/bin/ksh
SYMCLI_DB_FILE=/var/symapi/db/symapi_db.bin
/usr/symcli/bin/symmir -g bcv1 query > /tmp/bcv_list

The script works find if I submit in Unix promot, but it didn't work if I put the script in the cron. Any idea.

Thanks,

Simon

What is the exact entry your using in cron?
What are the permissions/ownership on the script?

I put in the full path of the script, the script is owned by root:sys and has "rx-" permission to owner, group.

Hi Simon

Presumably you're running the script from root's cron?

Also check /var/adm/cron/log.
Is the cron job listed there? It should show a rc??

Cheers

the cron daemon is running, I can see the script was execute from cron log. The output file didn't generate, but when I run the script in Unix promph it works fine.

Try exporting the SYMCLI_DB_FILE variable in your script.
(ie export SYMCLI_DB_FILE)
I've had problems with cron in the past when I didn't export the variable.

Besides adding 'export VARIABLE' as suggested by Con, you could also use an output log and add 'set -xv' to the script, to see exactly what it is doing. Remember cron is really stupid and does not like utilising any type of environment variables, so therefore all of them must be in the script.

Hi,

To debug the script problem, I always append output from every step of the script to a full path logfile, which permission could be 777.
Good luck.

I thought of a couple of things that you might check...

In addition to checking permissions, and exporting your variables, you should make sure that the script is running under root's crontab. Also, try sourcing the user's environmental files in the script. That would make your script look something like this:

#!/usr/bin/ksh
. /my/user's/home/directory/.profile
. /my/user's/home/directory/.kshrc
export SYMCLI_DB_FILE=/var/symapi/db/symapi_db.bin

/usr/symcli/bin/symmir -g bcv1 query > /tmp/bcv_list

This is the key:

When you login, your .profile is sourced which sets up your environment variables.

Cron runs in a pseudo environment. So any environment variables needed would have to be set in the script.

set -x will help you find what is not being set.

Hi Simon,

since you do not redirect errors, you might find error ouput in mail.
If the command ran, it should have created /tmp/bcv_list no matter what other errors come from the programme.
Can you post the crontab entry?

use:
#!/usr/bin/ksh
export SYMCLI_DB_FILE=/var/symapi/db/symapi_db.bin
/usr/symcli/bin/symmir -g bcv1 query > /tmp/bcv_list 2>&1

greetings,

Michael
