Oracle 10g/11g Linux:SMS the alert logs ORA- errors generated in timestamp

SMS Alert logs ORA- errors

This is something new in database administration part.Suppose DBA was out of office and got call from company manager to come to office.There is some problem in database.Generally DBA connect database and check connection possible or not then check any alert log entry.It is better if DBA and their company people got messages whenever any ORA- errors came in certain period of time.

For this,I found some solution to read alert log and send sms to respective people.
It is mandatory if we put database in archive log and where frequent archives generated.This is require because of the timestamp of archives used to get the start and end time of alertlogs entry.

This is all done through SHELL script and on linux machine.

Here it is the magical script can help to get the info of SMS by mail ans SMS.

This shell designed to read alerts of last 30 minutes.

#Go to bdump location
cd /oracle1/oradata/pindb/bdump/

#SMS duration
sms_first=`perl -e "use POSIX qw/strftime/; print strftime('%I:%M %p',localtime(time()-1800))"`
sms_last=`perl -e "use POSIX qw/strftime/; print strftime('%I:%M %p',localtime(time()))"`

#Current and previos time of alert
current_time=`perl -e "use POSIX qw/strftime/; print strftime('%a %b %e %H:%M.*%Y',localtime(time()-1800))"`
future_time=`perl -e "use POSIX qw/strftime/; print strftime('%a %b %e %H:%M.*%Y',localtime(time()))"`
#search the current time
first=`cat -n alert_pindb.log | grep -i "$current_time" | awk '{print $1}' | head -1`
#last=`cat -n test_kavya.log | grep -i "$future_time" | awk '{print $1}' | tail -1`
#1800(30 min)-60(1 min)
#Log the all activities of this shell
