Find session details sid/pid from concurrent request id

Oracle Performance Analysis - Long running Concurrent Requests

The following query can be used to find the sid,pid, spid for a specific concurrent request. If a program is running for long time and user requests to verify the root cause, this will help DBA to find the sid and then dba can go beyond this and look for sqlid, plan etc. This will be helpful while doing performance analysis

SELECT a.request_id,

       d.sid,

       d.serial#,

       d.sql_id,

       d.osuser,

       d.process,

       d.client_identifier "requestor" ,

       c.SPID

  FROM apps.fnd_concurrent_requests   a,

       apps.fnd_concurrent_processes  b,

       v$process c,

       v$session d

 WHERE     a.controlling_manager = b.concurrent_process_id

       AND c.pid = b.oracle_process_id

       AND b.session_id = d.audsid

       AND a.request_id = '&REQUEST_ID';

 

Create/update sql profile/ sql baseline in Oracle Database

Oracle Performance Tuning

How to create SQL baseline in Oracle database from the backend. 

1. Check for baseline if available, from the SQL-ID

SELECT sql_handle, plan_name, enabled, ACCEPTED,FIXED,created FROM dba_sql_plan_baselines WHERE signature IN ( SELECT exact_matching_signature FROM gv$sql WHERE sql_id='&SQL_ID');

or

SELECT b.sql_handle, b.sql_text, b.plan_name, b.enabled

 FROM   dba_sql_plan_baselines b, v$sql s

 WHERE  s.sql_id='&SQL_ID'

 AND    s.exact_matching_signature = b.signature;

2. Now load the baselines from cursor (If nothing suitable is available on the Query 1):

DECLARE

    ezplan NUMBER;

 BEGIN

    ezplan := sys.dbms_spm.load_plans_from_cursor_cache(sql_id=>'&SQL_ID');

 END;

 /

3. Next, run the select again to see how many are imported and which one is good plan:

SELECT sql_handle, plan_name, enabled, ACCEPTED,FIXED,created FROM dba_sql_plan_baselines WHERE signature IN ( SELECT exact_matching_signature FROM gv$sql WHERE sql_id='&SQL_ID');

If it is returning multiple rows, means multiple plans are available for this SQL-ID.

To check the cost and plans for individual plans run the below script:

from Cursor:

select plan_table_output from table(dbms_xplan.display_cursor('<sql_id>',null,'ADVANCED'));
