I have a simple script that stops and starts the services (of Oracle Hyperion)

#!bin/ksh

/path/to/dir/stop.sh

sleep 1200

/path/to/dir/start.sh

I have scheduled it for every night and it does run, however there is an issue with database connectivity afterwards. But when i run stop.sh and start.sh manually, there is no such issue. Obviously the job had not run completely.

Here’s the output from crontab -l

00 02 * * * /export/home/oracle/scheduled_restart.sh

Could someone please advise on the problem? Thanks.

    The usual cause for cron jobs to differ from command line during execution of the exact same code is environment, specifically the variables like ORACLE_SID, TWO_TASK, LD_LIBRARY_PATH, and so on.

    Assuming the oracle user own the crontab:
    When a job is run by crond it does the equivalent of su oracle, not su – oracle. Try doing something to ensure that the command sources everything the oracle user would normally source during login.

    To see what is going on:

    /export/home/oracle/scheduled_restart.sh && set > /tmp/my_variables.txt

    You do not need the /bin/sh if the /export/home/oracle/scheduled_restart.sh file is executable.
    It should have a shebang on line 1. ex: #!/bin/ksh for korn shell or whatever shell you use.
