Cron Job Issue

shameemsoft — Tue, 23 Feb 2010 12:09:02 GMT

Dear,

We have created one script to collect recent files(when this script executed, it will check less than one hour time stamp files) and zip that files and transfer to other server.

When i run the script manually, it is working properly.

I tried with cron job. But it is not taking any files & zip file is created with 0 bytes and transferred to other server.

I am confusing why it is not executing with correct output only in cron job.

Kindly clarify on this.

Thanks in Advance
Shameem

check on the "cron logs" to send some light on your problem

/var/adm/cron/log ? and also it could better if you can post "entry of your crontab" and location of the script which you are calling

Hello,

Try to set up in your srcipt the shell you are using and set the PATH variable (copy the value from profile)

Thanks a lot your quick response.

Hi Shameem,

Looks like environment and PATH for the commands in your script is not defined.

Define it PATH variable in your script or replace each command with its absolute path.

Regards!
Johnson

Edit your script

/home/eppadm/scripts/epp-sync-j2ee-daily.sh

And define the PATH in there (get it from profile)

As johnson said check the cronlogs whether is script is executing or not.

Also check for the absolute path of the script in your crontab.

Check for the permission of the script/file & the directory structure.should have execute permission for the script file for the owner of the sript/file.

Rgds.,

can you post the script /home/eppadm/scripts/epp-sync-j2ee-daily.sh

Re: Cron Job Issue

Horia Chirculescu — Tue, 23 Feb 2010 12:24:28 GMT

#!/bin/sh
#

PATH=/usr/sbin:/usr/bin:/usr/ccs/bin:.....

Copy the value from your user's profile.

Thanks for your response.

I updated PATH. i have taken path details from /etc/profile.

Still it is not working... Again i am telling this script is working properly when i execute manually :).

I have attached script in the attachment.

Re: Cron Job Issue

Horia Chirculescu — Tue, 23 Feb 2010 13:03:25 GMT

PATH=/usr/sbin:$PATH:/sbin:/home/root:/usr/local/bin:$JAVA_HOME

Not good enough...

As the user you are running "manually" the script and it is working, do

set

and copy PATH line

Then open your script and past the line there (delete this line)

I believe the only problem is with gzip but just to be sure, add the correct PATH variable as above.

"ipaddress "

I assume it is an IP address, not some variable?

Jupinder Bedi — Tue, 23 Feb 2010 13:06:57 GMT

you can set the path by using set command as follows

set pathname

and than try

Good luck

Johnson Punniyalingam — Tue, 23 Feb 2010 13:28:02 GMT

also it would be better if you can / direct the output for your script by crontab to "some logs" like >> /tmp/daily.log -> it can capture of the execution and we narrow down the problem

>>IP address<< as per IP attachment have exculded, becoz its confidential ..?

Re: Cron Job Issue

shameemsoft — Wed, 24 Feb 2010 04:58:35 GMT

Thanks for your response.

I removed IP & server name from the script and uploaded to ITRC :)

If I set a path using set command, will it update the existing path configuration? It is production host. Thats why i would like to reconfirm with you guys.

Thanks in Advance

if you run manually the script run as per your earlier post,

can we redirect to a log file to capture the output of your script while execution in crontab.
so that we will all know what causing the actual problem. Guess we are all shooting in the dark room.

Re: Cron Job Issue

shameemsoft — Wed, 24 Feb 2010 05:44:52 GMT

Thanks Johnson.

I tried with that option...find the log output

#cat /tmp/log.out
Waiting until tar is complete ...
Tar completed successfully
Waiting until gzip is complete ...
Gzip completed successfully

tar & zip is completed with 0 bytes.. if i run manually at same time, some files exists in zip.

Kindly clarify on this

Thanks in Advance

Create to different script one for data collection and another for zip and transfer. And add two different entry in cron with sufficient time between them.

Horia Chirculescu — Wed, 24 Feb 2010 06:05:08 GMT

Have you set the PATH variable like this:

>As the user you are running "manually" the script and it is working, do

set

and copy PATH line into your SCRIPT.

Please re-attach the modified script here.

>>>#cat /tmp/log.out
Waiting until tar is complete ...
Tar completed successfully
Waiting until gzip is complete ...
Gzip completed successfully<<<

as long as i see from above. time taken "tar" is too short. and between you can "use " sleep command optins

man sleep

"sleep - suspend execution for an interval"
