-bash: /usr/bin/crontab: Permission denied

By default de Oracle user has no priviledges to add cron jobs under SLES 10.
when trying to do so you will recieve an error which looks something close to this :

oracle@xxx:~> crontab -l
-bash: /usr/bin/crontab: Permission denied

The solution to this is to add the “trusted” group to the user oracle.
To so this , you can login as root and preform this command :

[]oracle@xxx:~> su
Password:
xxx:/ # usermod -G trusted oracle
xxx:/ # exit
[]oracle@xxx:~> crontab -l
-bash: /usr/bin/crontab: Permission denied

After have done so, you need to login with oracle again to let the changes work.

[]oracle@xxx:~> su - oracle
Password:
[]oracle@xxx:~> crontab -l
no crontab for oracle

You can now either use
[]oracle@xxx:~>crontab -e
(to add,remove or edit the oracle cron jobs)

Or use
[]oracle@xxx:~>crontab -l
(to simply list scheduled cron jobs foir the user oracle)
