In the example in the previous section, a password wasn t needed to use the role. However, you can specify that a role must be authorized before it can be used. You can specify role authorization in several ways: Database authorization: You use a password when a role is authorized by the database, as shown in this example: CREATE ROLE clerk IDENTIFIED BY password; Database authorization with a PL/SQL package: A developer can create a role and specify that a PL/SQL package be used to authorize that role. In the following example, the admin_role role is enabled by a module defined inside the hr.admin PL/SQL package: CREATE ROLE admin_role IDENTIFIED USING hr.admin;

Externally, by the operating system, network, or other external source: You can require that a role be authorized by an external source before it can be enabled, as shown here: CREATE ROLE accts_rec IDENTIFIED EXTERNALLY; Globally, by an enterprise directory service: You can also define a role as a global role, which means that a user can only be authorized to use the role by an enterprise directory service. The following statement creates a global role that can be authorized by a directory service: CREATE ROLE supervisor IDENTIFIED GLOBALLY;

// class Router public class Router : System.ComponentModel.Component { private System.Messaging.MessageQueue messageQueueVehiclesToInvoice; //

If you grant a user a role using the WITH ADMIN OPTION clause, the grantee can do the following: Grant the role to or revoke it from any user or other role in the database. Grant the role with the WITH ADMIN OPTION. Alter or drop the role.

You normally grant a role to a user. The user then can immediately exercise all the privileges encompassed by the role. However, you can grant a role to another role. In this case, the database will add all the privileges of the role being granted to the privilege domain of the grantee role.

If you grant a role to PUBLIC, the database makes the role available to all the users in your database. If you wish to give a certain privilege or role to all the users in the database, you simply grant this privilege or role to the PUBLIC user group, which exists in every database by default. This is not a recommended way to grant privileges, however, for obvious reasons.

public Router(System.ComponentModel.IContainer container) { // messageQueueVehiclesToInvoice.BeginReceive(); }

You can disable a user s role by inserting the appropriate row into the Product_User_Profile table in the SYSTEM schema. Listing 12-10 shows you how to insert a row into this table to disable the TEST123 role, which has been assigned to the user TESTER. Listing 12-10. Disabling a Role Using the Product_User_Profile Table SQL> INSERT INTO PRODUCT_USER_PROFILE(PRODUCT,userid,attribute,char_value) 2* VALUES('SQL*Plus','TESTER','ROLES','TEST123'); 1 row created. SQL> COMMIT; Commit complete. SQL> CONNECT tester/tester@finance1 Connected. SQL> SELECT * FROM hr.regions;; select * from hr.regions *ERROR at line 1: ORA-00942: table or view does not exist As you can see, once the TEST123 role is disabled, the TESTER user can t select from the database tables, and an error is issued when the SELECT is attempted.

When you want to reenable the TEST123 role, all you need to do is delete the appropriate row from the Product_User_Profile table, as shown here: SQL> DELETE FROM product_user_profile 2 WHERE userid='TESTER' 3* AND char_value = 'TEST123'; 1 row deleted. SQL> commit; Commit complete.

public Router() { // messageQueueVehiclesToInvoice.BeginReceive(); } private void InitializeComponent() { this.messageQueueVehiclesToInvoice = new System.Messaging.MessageQueue(); // // messageQueueVehiclesToInvoice // this.messageQueueVehiclesToInvoice.Path = "FormatName:DIRECT=OS:alessandra\\private$\\asapvehiclestoinvoice"; this.messageQueueVehiclesToInvoice.ReceiveCompleted += new System.Messaging.ReceiveCompletedEventHandler(this.OrderReceived); } private void OrderReceived(object sender, System.Messaging.ReceiveCompletedEventArgs e) { System.Messaging.XmlMessageFormatter formatter = new System.Messaging.XmlMessageFormatter(new Type[] {typeof(WorkOrder)}); System.Messaging.Message msg = messageQueueVehiclesToInvoice.EndReceive(e.AsyncResult); msg.Formatter = formatter; WorkOrder workOrder = msg.Body as WorkOrder; // start waiting for the next message messageQueueVehiclesToInvoice.BeginReceive(); FireMessage(workOrder); } public delegate void MessageHandler(WorkOrder theWorkOrder); public event MessageHandler OnMessage; void FireMessage(WorkOrder theWorkOrder) { if (OnMessage != null) OnMessage(theWorkOrder); } }

Dropping a role is simple. Just use the DROP ROLE command: SQL> DROP ROLE admin_user; Role dropped. SQL>

In addition to using roles and privileges, Oracle also enables data security through the use of views and stored procedures. You ve already seen in 5 how views on key tables or even table joins can not only hide the complexity of queries, but also provide significant data security.
