Shell Script to Monitor Data Guard Status

Here is a shell script that can be scheduled to monitor the status of the data guard. The best method for monitoring data guard and databases is to user Oracle Enterprise Manager Grid Control and setup  and Manage the Data Guard.

Environment Used to test the script.

OS: Enterprise Linux Server release 5.3
Database: 11.2.0.2
No of Standby DB: 1
Data guard  Type: Physical Standby

Below script will connect to primary database and query V$ARCHIVE_DEST_STATUS and V$ARCHIVED_LOG to get the data guard status and un-applied log sequence count. If the data guard status is in error or count of un-applied logs are greater than 2, a subroutine can be called to alert the DBA. Assume that DEST_ID 2 is Standby Database.
