After logging as an application user (oradba), when I issued “crontab -l” system throwed the below error

Error Message:

0481-103 Cannot open a file in the /var/spool/cron/crontabs directory


a) Create an empty file /var/spool/cron/crontabs/oradba
b) Change the ownership of the file to root.cron
c) Login as oradba and issue “crontab -l” to verify the cron.
