Triggers that fire after DML operations, such as an INSERT or a DELETE, are the most commonly used triggers in Oracle databases, but they aren t the only types of triggers you can use. Oracle provides powerful system-level triggers, such as those set to fire after database startup and before database shutdown. Login and logoff triggers are especially useful for database auditing. The following are the main types of system-level triggers that Oracle Database 11g offers: Database startup triggers: You can use these triggers mostly to execute code that you want to execute immediately after database startup. Logon triggers: These triggers provide you with information regarding the logon times of a user and details about the user s session. Logoff triggers: These triggers are similar to the logon triggers, but they execute right before the user s session logs off. DDL triggers: You can capture all database object changes with these triggers. Server error triggers: These triggers capture all major PL/SQL code errors into a special table. Let s look at a simple example that shows the potential of the special Oracle triggers for auditing users. This example first creates a simple table to hold logon data. Whenever a user logs in, the table captures several pieces of information about the user. By auditing the logoff items with another trigger, it is easy to find out how long the user was inside the database on a given day. Here are the steps involved in creating a logon/logoff auditing system using system-level triggers: 1. Create a test table called logon_audit: SQL> CREATE TABLE logon_audit( 2 user_id VARCHAR2(30), 3 sess_id NUMBER(10), 4 logon_time DATE, 5 logoff_time DATE, 6* host VARCHAR2(20)); Table created.

Create a pair of logon and logoff triggers: SQL> CREATE OR REPLACE TRIGGER logon_audit_trig 2 AFTER LOGON 3 ON DATABASE 4 BEGIN 5 INSERT INTO logon_audit 6 VALUES 7 (user, 8 sys_context('userenv', 'sessionid'), 9 sysdate, 10 null, 11 sys_context('userenv', 'host')); 12* END; Trigger created. SQL> CREATE OR REPLACE TRIGGER logoff_audit_trig 2 AFTER LOGOFF 3 ON DATABASE 4 BEGIN 5 INSERT INTO logon_audit 6 VALUES 7 (user, 8 sys_context('userenv', 'sessionid'), 9 null, 10 sysdate, 11 sys_context('userenv', 'host')); 12* END; Trigger created.

You could also use a DDL trigger to capture changes made to objects by users, including modification, creation, and deletion of various types of objects. You can capture a large number of attributes about the event and the user that sets off a DDL trigger. To capture some of the important attributes of a user event, you first need to create a table to log DDL changes. Once you have done that, you can create a DDL trigger like the one shown in Listing 12-16. In this example, the table is named DDL_LOG and the trigger is DDL_LOG_TRIG. Listing 12-16. Using DDL Triggers to Audit Users SQL> 2 3 4 5 6 CREATE OR REPLACE TRIGGER ddl_log_trig AFTER DDL ON DATABASE BEGIN INSERT INTO ddl_log (username, 7 change_date, 8 object_type, 9 object_owner, 10 database 11 ) 12 VALUES 13 (ora_login_user, 14 sysdate, 15 ora_dict_obj_type, 16 ora_dict_obj_owner, 17 ora_database_name) 16* END; Trigger created. SQL> Once the trigger is in use, you can query the DDL_LOG table to see the changes. As you can see here, users HR and SYSTEM have made several DDL-based changes to the database: SQL> SELECT * FROM ddl_log; USERNAME CHANGE_DATE OBJECT_TYPE -------- ----------- --------------HR 24-MAR-08 SYNONYM SYSTEM 24-MAR-08 OBJECTPRIVILEGE HR 24-MAR-08 TRIGGER SQL> OBJECT_OWNER ------------HR SYSTEM HR DATABASE_NAME ------------NINA NINA NINA GPS GUI GUID HTTP IANA IC IDL IETF IIOP IP J2EE JDK JIT JMS JTA JTS LC LCE LLC LPC MBB MDB MIL MOM MSMQ OMG OO OOP OS P2P PC PCB PGM In addition to using the standard Oracle auditing features described in the previous sections, you can also take advantage of Oracle s Flashback capabilities to audit changes made to a table s rows. For example, you can use the Flashback Query feature to examine a table s data at a past point in time. Using the Flashback Transaction Query, you can find out all the changes made to a row since a past point in time or an SCN. The Flashback Versions Query will return each version of a row that existed in the specified period. You can easily identify the user and the specific operation that resulted in any inappropriate or unauthorized modifications to data. Using the transaction details from this query, you can go ahead and identify the entire transaction(s) with the help of another flashback feature, Flashback Transaction Query. The Flashback Query, Flashback Versions Query, and Flashback Transaction Query features rely on undo data and are discussed in detail in 8. codeproject vb.net barcode generator Packages matching Tags:"Barcode" - NuGet Gallery
