Enable Trace and take tkprof

Step 1 : Check Request ID from Find Concurrent request screen (In my case Request ID is 1145)

Step 2 : Run below command to find SPID, provide concurrent request ID (1145 in my case) when prompted

SELECT a.request_id, d.sid, d.serial# ,d.osuser,d.process , 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;

REQUEST_ID        SID    SERIAL# OSUSER           PROCESS    SPID
—————----------------------------------------------------------------------------
   1145                  514            28         applmgr             17794        2987.
.

Step 3.1 : Check and confirm SPID on Database Node
$   ps-ef | grep 2987
  proddb   2987     1  0 13:30:43 ?        0:03 oracledbr12 (LOCAL=NO)

Step 3.2 : Set OSPID (2987 in my case) for ORADEBUG
SQL> oradebug setospid 2987

Step 3.3 : Enable trace for 10046 event with level 12
SQL> oradebug event 10046 trace name context forever, level 12

LEVEL 12 – Both Binds and Waits
LEVEL 8 – Only WAITS
LEVEL 4 – Only BIND Variables

Step 3.4 : Locate Trace file as
SQL>oradebug tracefile_name

/oracle/apps/proddb/10.2.0/admin/prod_CSDoracle/udump/ prod _ora_2987.trc

Wait for 15-20 minutes

Step 4 : Disable trace
SQL> oradebug event 10046 trace name context off

Step 5: Create tkprof file like
$ tkprof prod _ora_2987.trc prod _ora_2987.txt explain=apps/<****>  sort=(exeela,fchela) sys=no ---------------Provide apps password-----------
