Cron Job Not Running

Question

Oracle Linux 5.10

I can manually run the script "tblspc_usage.sh" successfully as the oracle user. I know this because it emails me a report.

But it not run at all from cron. It doesn't generate a log file.

[oracle@dub-ImrORA3 scripts]$ crontab -l
# user /bin/sh
SHELL=/bin/sh
# mail to oracle user
MAILTO=oracle
# run at 9:45 AM monday thur friday
45 09 * * 1-5 /home/oracle/scripts/tblspc_usage.sh 2>&1 /home/oracle/scripts/tblspc_usage.log

[oracle@dub-ImrORA3 scripts]$ ls -al tblspc_usage.sh
-rwxrwxr-- 1 oracle oinstall 2013 Jan 20 09:12 tblspc_usage.sh

Okay, here is the email in /var/mail/oracle /home/oracle/scripts/tblspc_usage.sh: line 15: sqlplus: command not found grep: body.log: No such file or directory

Here is my shell script:

#!/bin/sh
#
# tblspc_usage.sh

#
# Checks for tablespace usage exceeding 90% and email the details
# does not check undo or temp tablespaces

Answer 1

The message sqlplus: command not found gives the answer. Since you have an environment variable ORACLE_HOME set, put this line in your script after exporting ORACLE_HOME:

export PATH=$PATH:$ORACLE_HOME/bin

I also have a superstition of exporting TNS_ADMIN:

export TNS_ADMIN=$ORACLE_HOME/network/admin

I don't know if that's strictly necessary.

Answer 2

Seems like you updated your post with more information, like Bruce said, that error tells you that ORACLE_HOME path is missing. Update your script to include:

export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_SID=IMR1

I would still fix this in your cron:

# run at 9:45 AM monday thur friday
45 09 * * 1-5 /home/oracle/scripts/tblspc_usage.sh >> /home/oracle/scripts/tblspc_usage.log 2>&1

• Append to log: >>
• Redirect stderr to log file (in this case same as stdout): 2>&1
