Can Toad for Oracle do level 10046 or 10053 extended Tracing?
Toad for Oracle can do 10046 tracing. This is done by opening a Session Browser window, then right mouse clicking on a session, and selecting "Start trace." If the user takes that trace file and runs it through tkprof the output file will have explain plans.
10053 extended tracing is not currently available in Toad for Oracle.
Enhancement request 33247 has been submitted to Development for consideration in a future release of Toad for Oracle.
