Session Activity Queries

--> Checking session

select sesion.sid, sesion.username, optimizer_mode,

hash_value, address, cpu_time, elapsed_time, sql_text

from v$sqlarea sqlarea, v$session sesion

where sesion.sql_hash_value = sqlarea.hash_value

and sesion.sql_address = sqlarea.address

and sesion.username is not null

--> Get the rows fetched, it there is difference it means processing is happening

select b.name, a.value vlu

from v$sesstat a, v$statname b

where a.statistic# = b.statistic#

and sid =&sid

and a.value != 0

and b.name like '%row%'

--> Get the sql_hash_value

select sql_hash_value from v$session where sid='&sid';

Get the sql_Text

select sql_text v$sql from v$sql where hash_value =&Enter_Hash_Value;

Get the explain_plan

select

case when access_predicates is not null then 'A' else ' ' end ||

case when filter_predicates is not null then 'F' else ' ' end xms_pred,

cardinality xms_opt_card,

bytes xms_opt_bytes,

optimizer xms_optimizer

from v$sql_plan

where hash_value in (&SQL_HASH_VALUE)

and to_char(child_number) like '%';

Based the cost u can decide what to be done.

One of the solutions is to analyse the statistics

exec fnd_stats.gather_schema_statistics('ALL');
