Folks
Qs 1 Is the following SQL being fired by the Application (& NOT internally by
the Oracle Database)? ... Does the message "Module: JDBC Thin Client" prove
this?
Qs 2 Why is the "% Total" so High i.e. 49.7 ? Any approaches for handling this
issue?
Config:-
Oracle 10.2.0.1 (NON-RAC)
$ uname -a
HP-UX SPEHPPA1 B.11.11 U 9000/800 480485360 unlimited-user license
Cheers & Thanks V much
P.S. Bad SQL:-
SQL ordered by CPU DB/Inst: LOSDB/LOSDB Snaps: 552-554
-> Resources reported for PL/SQL code includes the resources used by all SQL
statements called by the code.
-> Total DB CPU (s): 121
-> Captured SQL accounts for 78.9% of Total DB CPU
-> SQL reported below exceeded 1.0% of Total DB CPU
CPU CPU per Elapsd Old
Time (s) Executions Exec (s) %Total Time (s) Buffer Gets Hash Value
