From Oracle FAQ
DBMS_PROFILER is a PL/SQL package, introduced with Oracle 8i, to profile (time) the run-time behaviour of PL/SQL code.
Example[edit]
-- Install the profiler... @?/rdbms/admin/proftab @?/rdbms/admin/profload
-- Create a test procedure to time... CREATE OR REPLACE PROCEDURE proc1 IS v_dummy CHAR; BEGIN FOR i IN 1..100 LOOP SELECT dummy INTO v_dummy FROM dual; END LOOP; END; /
-- Do the profilling and print a report... set line 5000 serveroutput on size 1000000 DECLARE v_run NUMBER; BEGIN DBMS_PROFILER.START_PROFILER('test','test1',v_run); proc1; DBMS_PROFILER.STOP_PROFILER; DBMS_PROFILER.ROLLUP_RUN(v_run); END; /
-- Look at output data SELECT runid, run_date, run_comment, run_total_time FROM plsql_profiler_runs ORDER BY runid; SELECT u.runid, u.unit_number, u.unit_type, u.unit_owner, u.unit_name, d.line#, d.total_occur, d.total_time, d.min_time, d.max_time FROM plsql_profiler_units u JOIN plsql_profiler_data d ON u.runid = d.runid AND u.unit_number = d.unit_number WHERE u.runid = 1 -- Change to run_id from the above query ORDER BY u.unit_number, d.line#;
