You are developing a user callout procedure to send an email to the helpdesk whenever a RAC database
instance fails to restart after node failure.

Explanation:
FAN callouts are server-side executables that Oracle Restart executes immediately when high availability
events occur.
You can use FAN callouts to automate the following activities when events occur, such as:
Opening fault tracking tickets
Sending messages to pagers
Sending e-mail
Starting and stopping server-side applications
Maintaining an uptime log by logging each event as it occurs
To use FAN callouts, place an executable in the directory grid_home/racg/usrco on both the primary and the
standby database servers. If you are using scripts, then set the shell as the first line of the executable. The
following is an example file for the grid_home/racg/usrco/callout.sh callout:
#! /bin/ksh
FAN_LOGFILE= [your path name]/admin/log/`hostname`_uptime.log
echo $* “reported=”`date` >> $FAN_LOGFILE &
Note: Oracle has proved options where a script or utility or application (called server side callout), if placed in
$GRID_HOME/racg/usrco directory, will be executed automatically.References: Expert Oracle RAC Performance Diagnostics and Tuning (2014), page 506
