To Enable PL/SQL Profiler manually in PL/SQL

PL/SQL Profiler data can be collected manually by enabling and disabling directly in PL/SQL.

This could be useful if testing directly from SQL*Plus / SQL Developer (i.e. outside of E-Business Suite).

This requires updating the PL/SQL code and re-compiling.

Care is also needed to ensure that the commands to enable and disable are placed at the correct points (where they will definitely be executed and capture all the necessary actions).

Enable PL/SQL Profiler using:

dbms_profiler.start_profiler(run_comment => ‘<comment>’, run_comment1 => ‘<comment 1>’);
Disable PL/SQL Profiler using:

dbms_profiler.stop_profiler;
Note that profiler data is stored in memory and is flushed into profiler tables when the profiler is stopped. It can be advisable to run dbms_profiler.flush_data at intervals to flush data to tables and free up memory.
