Generating SQL trace files

There are numerous ways to enable, disable and vary the contents of this trace. The following methods have been available for several versions of the database.
-- All versions.
SQL> ALTER SESSION SET sql_trace=TRUE;
SQL> ALTER SESSION SET sql_trace=FALSE;

SQL> EXEC DBMS_SESSION.set_sql_trace(sql_trace => TRUE);
SQL> EXEC DBMS_SESSION.set_sql_trace(sql_trace => FALSE);

SQL> ALTER SESSION SET EVENTS '10046 trace name context forever, level 8';
SQL> ALTER SESSION SET EVENTS '10046 trace name context off';

SQL> EXEC DBMS_SYSTEM.set_sql_trace_in_session(sid=>123, serial#=>1234, sql_trace=>TRUE);
SQL> EXEC DBMS_SYSTEM.set_sql_trace_in_session(sid=>123, serial#=>1234, sql_trace=>FALSE);

SQL> EXEC DBMS_SYSTEM.set_ev(si=>123, se=>1234, ev=>10046, le=>8, nm=>' ');
SQL> EXEC DBMS_SYSTEM.set_ev(si=>123, se=>1234, ev=>10046, le=>0, nm=>' ');

-- Available from SQL*Plus since 8i (commandline utility prior to this.
SQL> CONN sys/password AS SYSDBA; -- User must have SYSDBA.
SQL> ORADEBUG SETMYPID; -- Debug current session.
SQL> ORADEBUG SETOSPID 1234; -- Debug session with the specified OS process.
SQL> ORADEBUG SETORAPID 123456; -- Debug session with the specified Oracle process ID.

SQL> ORADEBUG EVENT 10046 TRACE NAME CONTEXT FOREVER, LEVEL 12;
SQL> ORADEBUG TRACEFILE_NAME; -- Display the current trace file.
SQL> ORADEBUG EVENT 10046 TRACE NAME CONTEXT OFF;

-- All versions, requires DBMS_SUPPORT package to be loaded.
SQL> EXEC DBMS_SUPPORT.start_trace(waits=>TRUE, binds=>FALSE);
SQL> EXEC DBMS_SUPPORT.stop_trace;

SQL> EXEC DBMS_SUPPORT.start_trace_in_session(sid=>123, serial=>1234, waits=>TRUE, binds=>FALSE);
SQL> EXEC DBMS_SUPPORT.stop_trace_in_session(sid=>123, serial=>1234);
The DBMS_SUPPORT package is not present by default, but can be loaded as the SYS user by executing the @$ORACLE_HOME/rdbms/admin/dbmssupp.sql script.

For methods that require tracing levels the following are valid values:
0 - No trace. Like switching sql_trace off.
2 - The equivalent of regular sql_trace.
4 - The same as 2, but with the addition of bind variable values.
8 - The same as 2, but with the addition of wait events.
12 - The same as 2, but with both bind variable values and wait events.
The same combinations are possible for those methods with Boolean parameters for waits and binds.
With the advent of Oracle 10g the SQL tracing options have been centralized and extended using the DBMS_MONITOR package. The examples below show just a few possible variations for enabling and disabling SQL trace in Oracle 10g.
-- Oracle 10g
SQL> EXEC DBMS_MONITOR.session_trace_enable;
SQL> EXEC DBMS_MONITOR.session_trace_enable(waits=>TRUE, binds=>FALSE);
SQL> EXEC DBMS_MONITOR.session_trace_disable;

SQL> EXEC DBMS_MONITOR.session_trace_enable(session_id=>1234, serial_num=>1234);
SQL> EXEC DBMS_MONITOR.session_trace_enable(session_id =>1234, serial_num=>1234, waits=>TRUE, binds=>FALSE);
SQL> EXEC DBMS_MONITOR.session_trace_disable(session_id=>1234, serial_num=>1234);

SQL> EXEC DBMS_MONITOR.client_id_trace_enable(client_id=>'tim_hall');
SQL> EXEC DBMS_MONITOR.client_id_trace_enable(client_id=>'tim_hall', waits=>TRUE, binds=>FALSE);
SQL> EXEC DBMS_MONITOR.client_id_trace_disable(client_id=>'tim_hall');

SQL> EXEC DBMS_MONITOR.serv_mod_act_trace_enable(service_name=>'db10g', module_name=>'test_api', action_name=>'running');
SQL> EXEC DBMS_MONITOR.serv_mod_act_trace_enable(service_name=>'db10g', module_name=>'test_api', action_name=>'running', -
> waits=>TRUE, binds=>FALSE);
SQL> EXEC DBMS_MONITOR.serv_mod_act_trace_disable(service_name=>'db10g', module_name=>'test_api', action_name=>'running');
The package provides the conventional session level tracing along with two new variations. First, tracing can be enabled on multiple sessions based on the value of the client_identifier column of the V$SESSION view, set using the DBMS_SESSION package. Second, trace can be activated for multiple sessions based on various combinations of the service_name, module, action columns in the V$SESSION view, set using the DBMS_APPLICATION_INFO package, along with the instance_name in RAC environments. With all the possible permutations and default values this provides a high degree of flexibility.
trcsess
Activating trace on multiple sessions means that trace information is spread throughout many trace files. For this reason Oracle 10g introduced the trcsess utility, which allows trace information from multiple trace files to be identified and consolidated into a single trace file. The trcsess usage is listed below.
trcsess [output=

] [session=] [clientid=]
[service=] [action=] [module=]

output=

output destination default being standard output.
session= session to be traced.
Session id is a combination of session Index & session serial number e.g. 8.13.
clientid= clientid to be traced.
service= service to be traced.
action= action to be traced.
module= module to be traced.
Space separated list of trace files with wild card '*' supported.
With all these options the consolidated trace file can be as broad or as specific as needed.
tkprof
The SQL trace files produced by the methods discussed previously can be read in their raw form, or they can be translated by the tkprof utility into a more human readable form. The output below lists the usage notes from the tkprof utility in Oracle 10g.
$ tkprof
Usage: tkprof tracefile outputfile [explain= ] [table= ]
[print= ] [insert= ] [sys= ] [sort= ]
table=schema.tablename Use 'schema.tablename' with 'explain=' option.
explain=user/password Connect to ORACLE and issue EXPLAIN PLAN.
print=integer List only the first 'integer' SQL statements.
aggregate=yes|no
insert=filename List SQL statements and data inside INSERT statements.
sys=no TKPROF does not list SQL statements run as user SYS.
record=filename Record non-recursive statements found in the trace file.
waits=yes|no Record summary for any wait events found in the trace file.
sort=option Set of zero or more of the following sort options:
prscnt number of times parse was called
prscpu cpu time parsing
prsela elapsed time parsing
prsdsk number of disk reads during parse
prsqry number of buffers for consistent read during parse
prscu number of buffers for current read during parse
prsmis number of misses in library cache during parse
execnt number of execute was called
execpu cpu time spent executing
exeela elapsed time executing
exedsk number of disk reads during execute
exeqry number of buffers for consistent read during execute
execu number of buffers for current read during execute
exerow number of rows processed during execute
exemis number of library cache misses during execute
fchcnt number of times fetch was called
fchcpu cpu time spent fetching
fchela elapsed time fetching
fchdsk number of disk reads during fetch
fchqry number of buffers for consistent read during fetch
fchcu number of buffers for current read during fetch
fchrow number of rows fetched
userid userid of user that parsed the cursor

$
The waits parameter was only added in Oracle 9i, so prior to this version wait information had to be read from the raw trace file. The values of bind variables must be read from the raw files as they are not displayed in the tkprof output.

The following section shows an example of gathering SQL trace for a session to give you an idea of the whole process.
Trace Example
The sql_trace_test.sql script creates a test table and a procedure that populates it. This procedure will be the subject of our example trace.

sql_trace_test.sql
CREATE TABLE sql_trace_test (
id NUMBER,
description VARCHAR2(50)
);

EXEC DBMS_STATS.gather_table_stats('test', 'sql_trace_test');

CREATE OR REPLACE PROCEDURE populate_sql_trace_test (p_loops IN NUMBER) AS
l_number NUMBER;
BEGIN
FOR i IN 1 .. p_loops LOOP
INSERT INTO sql_trace_test (id, description)
VALUES (i, 'Description for ' || i);
END LOOP;

SELECT COUNT(*)
INTO l_number
FROM sql_trace_test;

COMMIT;

DBMS_OUTPUT.put_line(l_number || ' rows inserted.');
END;
/
SHOW ERRORS
Gathering the statistics on the empty table may seem odd, but this prevents any dynamic sampling being added to the trace file contents, which would only serve to complicate the file.
Before we start to trace the procedure we should identify the trace file that will be produced. The name of the trace file is based on the current value of the user_dump_dest, the session's process id and the instance name. The identify_trace_file.sql script combines these values to produce the expected trace file name.

identify_trace_file.sql
SET LINESIZE 100
COLUMN trace_file FORMAT A60

SELECT s.sid,
s.serial#,
pa.value || '/' || LOWER(SYS_CONTEXT('userenv','instance_name')) ||
'_ora_' || p.spid || '.trc' AS trace_file
FROM v$session s,
v$process p,
v$parameter pa
WHERE pa.name = 'user_dump_dest'
AND s.paddr = p.addr
AND s.audsid = SYS_CONTEXT('USERENV', 'SESSIONID');
If you are using a windows environment you will need to alter the "/" to a "" in the concatenated string. The expected output from this script is displayed below.
SQL> @identify_trace_file.sql

SID SERIAL# TRACE_FILE
---------- ---------- ------------------------------------------------------------
130 26739 /u01/app/oracle/admin/DEV/udump/dev1_ora_367660.trc

1 row selected.

SQL>
Now we know the name of the trace file we can enable tracing, execute the procedure and disable tracing.
SQL> ALTER SESSION SET EVENTS '10046 trace name context forever, level 8';

Session altered.

SQL> SET SERVEROUTPUT ON
SQL> EXEC populate_sql_trace_test(p_loops => 5);
5 rows inserted.

PL/SQL procedure successfully completed.

SQL> ALTER SESSION SET EVENTS '10046 trace name context off';

Session altered.

SQL>
The contents of the file are listed below. The output looks a little confusing, but you can identify the individual statements and their associated waits and statistics.
