Question SH Script Execution Problems with Cronjob
Hi,

I have created a sh script to startup and shutdown the oracle database, when I execute the script thru command line it execute successfully, but when I call the script thru cronjob it does not execute.

The scripts are as follows:
Code:
 
LOG=/oracle/times.log
export ORACLE_SID=prod
echo $ORACLE_SID" Standby Database Open READ ONLY initiated   " `date` >> $LOG
sqlplus "/as sysdba"<<EOF
recover managed standby database cancel;
shutdown immediate;
startup mount;
alter database open read only;
EOF
echo $ORACLE_SID" Standby Database Open READ ONLY completed   " `date` >> $LOG

Code:
 
LOG=/oracle/times.log
export ORACLE_SID=prod
echo $ORACLE_SID" Standby Database Close READ ONLY initiated  " `date` >> $LOG
sqlplus "/as sysdba"<<EOF
shutdown immediate;
startup nomount;
alter database mount standby database;
alter database recover managed standby database disconnect from session;
EOF
echo $ORACLE_SID" Standby Database Close READ ONLY completed  " `date` >> $LOG
echo $ORACLE_SID" Standby Database Recovery Mode Started      " `date` >> $LOG
echo "===============================================================================" >> $LOG

Cron job is as follows:

Code:
 
00 0,9,12 * * * sh /oracle/scripts/standby_open_reporting.sh
00 2,21,13 * * * sh /oracle/scripts/standby_close_reporting.sh


Below is output of times.log file

Code:
prod Standby Database Close READ ONLY initiated   Wed Jun 29 21:00:00 PKST 2011
prod Standby Database Close READ ONLY completed   Wed Jun 29 21:00:00 PKST 2011
prod Standby Database Recovery Mode Started       Wed Jun 29 21:00:00 PKST 2011
===============================================================================
prod Standby Database Open READ ONLY initiated    Thu Jun 30 00:00:00 PKST 2011
prod Standby Database Open READ ONLY completed    Thu Jun 30 00:00:00 PKST 2011
prod Standby Database Close READ ONLY initiated   Thu Jun 30 02:00:00 PKST 2011
prod Standby Database Close READ ONLY completed   Thu Jun 30 02:00:00 PKST 2011
prod Standby Database Recovery Mode Started       Thu Jun 30 02:00:00 PKST 2011
===============================================================================
prod Standby Database Open READ ONLY initiated    Thu Jun 30 09:00:00 PKST 2011
prod Standby Database Open READ ONLY completed    Thu Jun 30 09:00:00 PKST 2011

You need to set the proper environment variables.

so cron finds sqplplus

Thanks!
I haved added the environment variables in my shell script and it is running fine now thru cron job.
Can I executed the .profile in shell script instead of adding the environment variables in shell script?

you can add.

but instead of adding the .profile, you can create a file and out the necessary variables and source it

You probably use ksh as your scripting language. Then it is advisable to NEVER rely on any environment (like the one set in ~/.profile or ~/.kshrc) but always set it explicitly. This way you never have to worry about the script being called from command line, cron or wherever.

I have for this a central file /usr/local/lib/ksh/f_env where i store all the necessary PATH- and other environment-variables, do things i want done in all my scripts (for instance: start some logging so that if a script breaks i can at least find out where it was broken), etc.. All my scripts source in this script as the first thing to do. Here is an example:

Code:
#! /bin/ksh
# This is an example script

. /usr/local/lib/ksh/f_env

# here starts the scripts code
command_1
command_2
[...]
exit 0

I hope this helps.
