Linux Script doees not executed as cronjob

Question

I have created a script b.sh as follows to get the status of Oracle Database
[oracle@accurman1 tmp]$ cat b.sh
#! /bin/bash
$ORACLE_HOME/bin/sqlplus -s < /tmp/1.sql >> /tmp/mylog.log
[oracle@accurman1 tmp]$
[oracle@accurman1 tmp]$ cat /tmp/1.sql
connect sys/xxx@orcl as sysdba
set heading off
set feedback off
set verify off
select 'STATUS:'||status from v$instance;
select 'MODE:'||log_mode from v$database;
[oracle@accurman1 tmp]$
when execute manually from command promp it executes properly and I get the sql output in mylog.log file
However if I schedule the script, b.sh , as cron job then it does not executes... and do not through any error.....
What is wrong here?

#! /bin/bash
$ORACLE_HOME/bin/sqlplus -s < /tmp/1.sql >> /tmp/mylog.log
What is wrong here?Environment. Cron doesn't know the enviroment of (oracle) user.
So set the environment (at least ORACLE_HOME) in your b.sh script.
as cron job then it does not executes... and do not through any error.....Usually when error occurs during cron execution it is mailed to user's inbox.
So try to log as that user (su - oracle) and try to execute "mail" command.
The other way how you can log the output and errors is (crontab entry example):
5 * * * * /home/oracle/bin/my_cron_script >> /tmp/my_cron_script.log 2>&1
