In multitier environments, the middle tier passes a client s request through several database sessions. It s hard to keep track of the client across all these database sessions. Similarly, when you use shared server architecture, it s hard to identify the user session that you re tracing at any given time. Because multiple sessions may use the same shared server connection, when you trace the connection, you can t be sure who the user is exactly at any given time the active sessions using the shared server connection keep changing throughout. In the cases I described earlier, tracing a single session becomes impossible. Oracle Database 10g introduced end-to-end tracing, with which you can uniquely identify and track the same client through multiple sessions. The attribute CLIENT_IDENTIFIER uniquely identifies a client and remains the same through all the tiers. You can use the DBMS_MONITOR package to perform end-to-end

You use the Oracle PL/SQL package DBMS_MONITOR to set up end-to-end tracing. You can trace a user session through multiple tiers and generate trace files using the following three attributes: Client identifier Service name Combination of service name, module name, and action name You can specify a combination of service name, module name, and action name. You can also specify service name alone, or a combination of service name and module name. However, you can t specify an action name alone. Your application must use the DBMS_APPLICATION_INFO package to set module and action names. The service name is determined by the connect string you use to connect to a service. If a user s session isn t associated with a service specifically, the sys$users service handles it. Let s use two procedures belonging to the DBMS_MONITOR package. The first one, SERV_ MOD_ACT_TRACE_ENABLE, sets the service name, module name, and action name attributes. The second, CLIENT_ID_TRACE_ENABLE, sets the client ID attribute. Here s an example: SQL> EXECUTE dbms_monitor.serv_mod_act_trace_enable (service_name=>'myservice', module_name=>'batch_job'); PL/SQL procedure successfully completed. SQL> EXECUTE dbms_monitor.client_id_trace_enable (client_id=>'salapati'); PL/SQL procedure successfully completed. SQL> You can use the SET_IDENTIFIER procedure of the DBMS_SESSION package to get a client s session ID. Here s an example showing how you can use a logon trigger and the SET_IDENTIFIER procedure together to capture the user s session ID immediately upon the user s logging into the system: SQL> CREATE OR REPLACE TRIGGER logon_trigger AFTER LOGON ON DATABASE DECLARE user_id VARCHAR2(64); BEGIN SELECT ora_login_user ||':'||SYS_CONTEXT('USERENV','OS_USER') INTO user_id FROM dual; dbms_session.set_identifier(user_id); END; Using the value for the client_id attribute, you can get the values for the SID and SERIAL# columns in the V$SESSION view for any user and set up tracing for that client_id. Here s an example:

SQL> EXECUTE dbms_monitor.session_trace_enable (session_id=>111, serial_num=>23, waits=>true, binds=>false); You can now ask the user to run the problem SQL and collect the trace files so you can use the TKPROF utility to analyze them. In a shared server environment especially, there may be multiple trace files. By using the trcsess command-line tool, you can consolidate information from multiple trace files into one single file. Here s an example (first navigate to your user dump or udump directory): $ trcsess output="salapati.trc" service="myservice "module="batch job" action="batch insert" You can then run your usual TKPROF command against the consolidated trace file, as shown here: $ tkprof salapati.trc output=salapati_report SORT=(EXEELA, PRSELA, FCHELA)

Note In this chapter, you saw how to enable SQL tracing using the SQL Trace facility, the DBMS_SESSION package, and the DBMS_MONITOR package. You should use one of the two packages, rather than SQL Trace, to trace SQL statements. You can use any one of these three methods to set up a session-level or instance-wide trace. Be careful about tracing the entire instance, because it ll lead to excessive load on your instance, as well as produce too many voluminous trace files.
