Logs and Out files will be generated under $DBA_SCRIPTS_HOME/logs/$HOST_NAME

So make sure to create logs/$HOST_NAME directory under $DBA_SCRIPTS_HOME before executing 

the script.

Once the script is ready, then as per the requirement please schedule it in crontab/OEM.

Execute the Script as below:

Syntax :  sh <script_name> <ORACLE_SID> 

$ cd $HOME/DBA_MON/bin
$ sh WorkflowStatusCheck.sh ORCL

This script will send alert notification if one or more workflow mailer components are down.
