Method to find Oracle high consumption statements

Before you can run the following script, you need to find the starting and ending snapshot Numbers: begin_snap and end_snap with the SQL that generated the AWR report (the program script is normally stored in the RDBMS /admin under $ORACLE_HOME, named awrrpt-sql, and you need to enter the range of days to generate the AWR report).

Save the script output to notepad TXT, and change the notepad suffix to.html, so you can output the following web content:
