Hi i ahve configured cronjobs for certain backups on my clearcase server but i am getting some dump emails stating like CLBU VOB Admin in subject and the contents says like

Cron: can't change directory to your home directory.
Your commands will not be executed.

kindly suggest

Dig into scripts which you configured running from cron.
Try to start scripts from user, not from cron. It is a work ok ?

does it have something to do with the var/spool/cron crontab.root file
this is what it says

@(#) $Revision: 72.1 $

This is a sample crontab file for the super-user.


log kernel diagnostic messages every 10 minutes
05,15,25,35,45,55 * * * * /usr/sbin/dmesg - >>/var/adm/messages

Sample nightly invocation of calendar. If you wish to run calendar,
just uncomment the next line.
0 4 * * * exec /usr/bin/calendar -


is there a way to findout which script is a problem as i have 4-5 scripts running
and i can't run each of them right away there are some backup scripts also

Aaa.
You need search in /etc/cron.d /etc/cron.daily /etc/cron.montly /etc/cron.weekly
depends on your distribution.

there is nothing like /etc/cron.d or etc/cron.daily............ it only have a cron exeutable file actually its HPUX11.0

Hi manoj,

You say that you're using HP UX....I dont know if crontabs have different format in HP UX, but In Red Hat 9, this is not the correct format....

The format in Red Hat is

Minutes Hour DayOfMonth Month DayOfWeek Command

So a sample crontab can be

30 4 * * * /usr/bin/dmesg

(That means every day at 4:30 am, run the command 'dmesg'. So there are only 6 fields in a crontab file in Red Hat Linux. If HP UX has a similar format then take a look at your crontab file:


This is a sample crontab file for the super-user.


log kernel diagnostic messages every 10 minutes
05,15,25,35,45,55 * * * * /usr/sbin/dmesg - >>/var/adm/messages


The line below matches more with the Red Hat format

Sample nightly invocation of calendar. If you wish to run calendar,
just uncomment the next line.
0 4 * * * exec /usr/bin/calendar

The line in bold is not correct unless HP UX follows a different format then Red Hat...so check the format of the command.

Also, check if users have execute permissions to their home directories set properly, otherwise, you wont be able to run a script that resides in the user's home directory.

just a correction...the line in bold is correct as u r running the script every 10 minutes...

In that case check for the permissions for the user's home directories...Let see if we can pick up something thats causing the error...

You can also check if the user for which these cron jobs are being executed is not mentioned in the file

/etc/cron.deny

Regards,

amit

If we speak about hp-ux, not linux that
man cron and check this files and dirs
FILES
/var/adm/cron Main cron directory
/var/spool/cron/atjobs Directory containing at and batch job files
/var/spool/cron/crontabs Directory containing crontab files
/var/adm/cron/log Accounting information
