Cron log showing error as rc=1

I have a cron user abcd and the script file is /home/abcd/script/auto_run_db_extract.ksh

the user abcd has a cron file under /var/spool/cron/crontabs/abcd

The crontab entry in abcd is

01 19 * * * /home/abcd/script/auto_run_db_extract.ksh

Till Dec 12th the script was executing fine, but since Dec 13th the script is not working.

No changes made to crontab file or to the script.

Since Dec 13th the cronlog entry shows

May I know why the script failed and what is the meaning of rc=1 in cron log file.

Re: Cron log showing error as rc=1

looks like there are syntax errors in the script... The script should always start with #!/usr/bin/sh

You can also try:-
# /sbin/init.d/cron stop
# /sbin/init.d/cron start

try PATH=${PATH}:${ORACLE_HOME}/bin
${PATH} is another way of writing $PATH.

Re: Cron log showing error as rc=1

Hi:

Cron is telling you the return code (rc) of the last command. In your case the last command returned a value of one (1).

Regards!

Re: Cron log showing error as rc=1

Thanks Grayh,

The script file has not been modified till Dec13 and it has been working till then.

Also the cron is executing this file using /usr/bin/sh only.

With regard to path also the script is not modified. I dont know what happened all of a sudden.

Let me restart my cron and will let you know.

Thanks for your reply.

Re: Cron log showing error as rc=1

If rebooting the cron works... it should be fine..

>No changes made to crontab file or to the script.

So you may try to run the script independent of cron.

Also check the permissions for file if they might have changed, and your scripts might be failing.

And check if the directory for cron.allow and at.allow is "/usr/lib/cron"

Nothing has changed on your computer? A full filesystem (ie, /home), you have exceeded filesystem quotas, a change in the database logins, scp is failing due to a public key problem, etc... For most commands, the return code is the error number, also known as errno, and errno=1 means:

from /usr/include/sys/errno.h:
errno 1 = EPERM /* Not super-user */

[EPERM] Not owner. Typically, this error indicates an attempt
to modify a file in some way forbidden except to its
owner or the superuser, such as to change its mode. It
is also returned for attempts by ordinary users to do
things for which they need, but lack, a special
privilege.

Even though this is being run as root, your script depends on other subsystems such as sql and another computer. Don't run it in cron until you run it from a root login shell. And run it this way:

sh -x /home/abcd/script auto_run_db_extract.ksh

The -x will trace each step. If that works OK, put the line:

set -x

at the top of your script and let cron run it. You'll get an email with the trace and be able to see which line is failing.

> Also the cron is executing this file using /usr/bin/sh only.

It is a bad idea to allow any scripts without the #!/usr/bin... header line. Without this line, someday a script will be run from a non-standard shell and cause problems. Always include #!/usr/bin/sh for your POSIX shell scripts.

Re: Cron log showing error as rc=1

Thanks Grayh,

I have rebooted cron. I need to wait till the server time tickles 19:01.

With regard to running the script manually,
the user is saying that the @ symbol in the following line is giving some error.

sqlplus -S "reporting_user/fnsw@ABCPRDB" @/home/abcd/script/reporting_db_extract.sql

I dont have the exact error message now. So what the user is doing is he logs on to sqlplus and does his tasks which goes smoothly.

I will let you know after 19:01 hrs CST.

Thanks

Re: Cron log showing error as rc=1

My users also had the @ issue many a times... Just that their .profile needs a bit of modification...

'stty -a' should show as:

kill = ^U -------->which is the default terminal setting.

& stty kill ^U

Re: Cron log showing error as rc=1

I seriously doubt that stopping / starting cron will help here.

The user that is running this job needs to check their mail on the HP-UX system. Cron will send an e-mail to the user account that runs the job EVERY TIME it runs.

From this e-mail you should be able to see how / where it is failing.

I would modify the line in cron so that I get an e-mail after the script runs. Do something like:

01 19 * * * /home/abcd/script/auto_run_db_extract.ksh 2>&1 | mailx -s "Output from auto_run_db_extract.ksh cron job" user@domain.com

Re: Cron log showing error as rc=1

Bill note "Even though this is being run as root, your script depends on other subsystems such as sql and another computer."

Actually, he said user "abcd" ran the job out of cron, so it gets id / permissions, correct?

I'd suspect a (possibly inadvertant) change in one of the directories noted for the "scp" or the "rm"....possibly others depending upon what's in "reporting_db_extract.sql"

also of note is the fact that the orignal script (or at least the portion posted) will *NOT* run if it can't find "lost+found", which makes absolutely no sense at all, as it doesn't use anything located there.

interesting that the original script is .ksh, but doesn't have the #! line...
