I have been working on tracing session statements to derive the explain plan and LIO values. What does one do to accomplish the same when PL/SQL code is encountered. Extended SQL Tracing provides no explain plan or fetch(buffer gets) values Also, to confirm is it disk or query fetch divided by count to determine LIO figure? Thanks -- ..
