Bind Capture History
As of 10g, Oracle captures the bind value and stores it into the repository(AWR), but with following restrictions.

• Captured periodically(_cursor_bind_capture_interval), not at real time.
• Captured under maximum size(_cursor_bind_capture_area_size)
• Only bind variables in WHERE clause are captured

Ouch! Too many restrictions, aren’t they?

Simple demonstration:

UKJA@ukja102> var bid1 number;
UKJA@ukja102> var eid1 number;
UKJA@ukja102>
UKJA@ukja102> exec :bid1 := dbms_workload_repository.create_snapshot;
