First Install UTL_MAIL ###

To install UTL_MAIL:

sqlplus sys/****
 @$ORACLE_HOME/rdbms/admin/utlmail.sql
 @$ORACLE_HOME/rdbms/admin/prvtmail.plb

### Create a Reporting User ###

create user tctreport identified by tctreport;

grant connect to tctreport;

grant dba to tctreport;

sqlplus tctreport/tctreport

## Grant TCTREPORT User permission to execute UTL_MAIL ##

sqlplus "/as sysdba"

grant execute on sys.utl_mail to tctreport;

## Create Directory MY_DIR as location to generate the files ###

create or replace directory MY_DIR as '/ACFS/report';

grant read, write on directory MY_DIR to tctreport;
