How to use Toad to trace what sql are being executed by my application? All I want to do is trace what SQL / PL/SQL procedures are being executed by my application and what parameters are being passed?
You can not use TOAD to trace SQL fired by external application, but you can utilize session browser to see what queries are being executed on session basis.There is also oracle utility called tkprof which can be used to profile SQL.Also take a look at this : Oracle: is there a tool to trace queries, like Profiler for sql server?
