script - April 30, 2009 at 20:00 PM by Amit Satpute
Explain how to run any oracle script file through shell script in UNIX.
A shell script is simply a text file containing a sequence of commands. When a
file or script is run, it executes the commands contained in the file
Scripts written to interact with Oracle Database sometimes require the entry of
sensitive information such as a database password.
The stty –echo command turns off the screen echo. After the sensitive
information has been read and stored in a variable, the display can be turned
on again with stty echo.
Here are a few script commands:
-
get_inv_location.sh
To determine inventory location
-
list_oracle_homes.sh
To determine the ORACLE_HOME for a given database
-
search_log.sh
A variety of logs are generated by Oracle products like the database alert log,
installation de-installation logs. The following script iterates over a file
passed to it as an argument.
Script:
cat $1 | grep ORA- > alert.err
if [ ‘cat alert.err|wc -l‘ -gt 0 ]
then
mail -s "$0 $1 Errors"
admin@careerride.com < alert.err
fi
