cron not running

Ragni Singh — Thu, 10 Mar 2005 20:21:40 GMT

Hi all, have a dilemma here. I have a cronjob that runs sucessfully on the command line but it fails out of cron. Does anyone know what could be causing this issue? I have a system going in production so I need to get this resolved right away. Thanks for your time and points will be assigned.

Different behavior in and out of cron is almost always due to differences in the environment.

add a line to the script:

env > /tmp/$env.txt

Let cron run it and then run it manually.

diff the two files.

There will be different and when corrected the behavior should be consistent.

Hi,
Check your env,Cron runs in posix born shell.Also check your syntax when you crontab -e.

Good Luck,

Hi Chand,

I suggest you can export environment values in the crontab to have a try. For example:
crontab -e
====================
export xxx=xxxx
*/5 * * * * /test.sh
=====================

Sanjith,
Its most of the time as mentioned by others due to environment not being set properly.
If you are having problems trying to figure it out, post it here and the one having sharp eyes will get it first :)

Hi Sanjit,

as all mentioned before, set all needed variables before job is running

bellow is example for my Oracle env.
#!/bin/bash
export ORACLE_SID="SMS"
export TWO_TASK=SMS
export ORACLE_HOME="/opt/Oracle"
export PATH="/usr/bin/:$ORACLE_HOME/bin:"

This is the problem. we have elm installed in /usr/local/bin/elm. When I run the script from the command line, it is able find elm and it runs. When I run the same thing out of cron, my output says it is not able to find elm...elm: command not found. The user has a search patch in his profile to search /usr/local/bin.

Also I don't know if it makes a difference but my elm permission is the following..

-rwxr-sr-x 1 bin mail 325106 Mar 10 13:57 elm

Any help is appreciated and points will be assigned.

Hello, thanks for all the time and help. Actually to make it work, I ended up copying elm to /usr/bin.
