you can use this script. in an non-interactive fashion without executing the script. through awrrpt, then do something similar to the following:

define inst_num = 1;

define num_days = 3;

define inst_name = 'testdb';

define db_name = 'testdb';

define dbid = 2591037507;

define sql_id = 'abcdefabcdefa';

define begin_snap = 71;

define end_snap = 72;

define report_type = 'text';

define report_name = awr_sql_report_71_72.txt
