I. description

Today, I configured a linux machine with crontab. I hope to run two import data scripts at 0 o'clock and 14:00 every day, but after the configuration is done. Upon inspection, it is found that the script did not run successfully, so you need to check the reason and deal with it.

Second, troubleshooting

1. Check the crond service

[root@testdb ~] # service crond status

Crond (pid 31955) is running …

two。 Check the system log

Query / var/spool/mail/oracle log found error message / home/oracle/impdp_xf.sh: line 2: impdp: command not found

This found no reason for failure, the command was not found, it seems to be caused by the lack of environment variables.

3. Problem handling

It works after adding source / home/oracle/.bash_profile to the execution of the / home/oracle/impdp.sh script.

On the crontab problem inspection and handling methods to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
