Answer 1

Trace a session.
1)Logout all sessions from the database
2)Login to application (ensure that only one session is available)
3)sqlplus trace/trace@026
4)check the sid and serial# of the session from v$session
Use the following query
SQL> select username,to_char(logon_time,'DD-MON-YYYY HH:MI:SS') from v$session where username='<db username>' order by logon_time;
SQL>exec sys.dbms_system.set_sql_trace_in_session(sid,serial#,TRUE);
5)now execute the report/transaction.
6)once the activity is over
SQL>exec sys.dbms_system.set_sql_trace_in_session(sid,serial,FALSE);
7)Now the trace file will be available in the udump folder of the database ip 10.44.0.26
Userid/password: trace/trace
The trace wil be available in /oracle/admin/orcl/udump
8)To find the name of the trace file use the below query
select spid from v$process where addr=(select paddr from v$session where sid=<enter the SID>);
This will give the name of the file
If you are not able to identify the trace file then please remove all files in udump before starting trace.
9) ftp the trace fil to ur local pc and issue the tkprof command
TKPROF <trace file (like D:\orcl_8853.trc)> D:\trace.txt explain=Oracle username/password (application user) sort=(prsela,exeela,fchela)
This will give trace file in readable format(you need to have 10g client on your pc for tkprof to work)
