E-Mail notification When There is a New Entry in ALERT log

By DatabaseJournal.com Staff



>>Script Language and Platform: Oracle
Most of the Alert scripts found in the Books sends duplicate mails to the user.This script is developed to avoid the duplication. It consists of two scripts.Alert_master.sh is the main script which will call alert.sh for all instances in your server.Please edit the scripts to suit your environments.
