Queries are derived from the view V$SQL_MONITOR for OEM, and inbuilt query.
Use query something like below:
select sid, sql_id, sql_exec_id, to_char(sql_exec_start,'DD-Mon-YY HH24:MI:SS') sql_exec_start, sql_plan_hash_value plan_hash_value,
elapsed_time ， buffer_gets, disk_reads
from v$sql_monitor
where sql_id like nvl('&sql_id',sql_id)
