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:-
