6. Drop the partitioned table.

Cronjob Doesn't Source Profile By Default

The script runs perfectly in command line won't necessarily run in cronjob. The most possible reason for this is that 'PATH' is not set in the script because by default cronjob won't source '.profile'. And user won't notice this because if user runs the script in command line, he's already sourced his profile. You should include it in your crontab shells or run commands in a way they source profile.
