Cron Issues

Jeff_Stark · July 11, 2007, 4:06pm

Hello everyone…

RT 3.6.3, RHEL, Oracle DB.

I have a cron job I created in cron.hourly…its pretty simplistic and
the command works great when I run it directly. Being very new to
Linux, I was hoping one of you may notice something simple that I am
missing here.

#!/bin/sh

/opt/rt3/bin/rt-crontool --search RT::Search::FromSQL --search-arg “(
Status = ‘new’ OR Status = ‘open’ OR Status = ‘stalled’ ) AND (
‘CF.{Severity Level}’ LIKE ‘Sev 2 (Premier Support ONLY)’ ) AND (
‘CF.{Customer}’ NOT LIKE ‘%§’ AND ‘CF.{Customer}’ NOT LIKE ‘%(ep)’ )”
–action RT::Action::DemotePremierLevel

Thanks,

-Stark

Do you have any output from a cron run of this? It could be that the
cron invocation is not getting the Oracle environment variables it needs.

The only item in /var/log/cron is:

Jul 11 09:01:01 infrt01 crond[23295]: (root) CMD (run-parts
/etc/cron.hourly)

Is there somewhere else I should look?

I think any output (stdout or stderr) from the cron job that isn’t
explicitly redirected is mailed to the crontab owner. So there may be
a mail message that contains a clue.

Excellent! Had no idea…you are correct, it is Oracle Connectivity
that is causing the issue.

Any ideas how I solve this? I used the priority escalation script as a
template.

Another guess - do you have LD_LIBRARY_PATH defined? I think
$ORACLE_HOME/lib should be included in this path.

Yes, that is defined.

It’s been a long while since I dealt with this issue, but I used to
have a file I called ~/.oracle, which set all the Oracle-related env
variables. I sourced this from my shell start up file (e.g. .bashrc)
and also in each crontab entry that needed Oracle access. That way I
was sure that both command-line and cron jobs were getting the same
Oracle environment.

This might be trivial but make sure the job is running the job as the
user you expect. If cron.hourly is being executed as root then it may
be reading the wrong files to setup the environment.

Jeff_Stark · July 11, 2007, 7:50pm

Thanks, yes, actually I am expecting it to run as root. (I know bad
karma to follow)

But I am just trying to get it working. I have tried forcing the
loading of .bash_profile and have also tried adding the following to the
script:
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/client_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib

But I still get this error:

I got past the Oracle issues, so that all is working now…thanks so
much for all the help.

I can run the script directly and it works fine. However, when running
under CRON I get a new error now:

: bad interpreter: No such file or directoryotePremier.cron: /bin/sh
/etc/cron.hourly/RT-Resolved.cron:

Any thoughts?
