Info

194 CHAPTER 9 TAKING CONTROL Figure 9-8 is particularly interesting because it shows usage information of different Oracle features. You can use this information to check whether your organization is suitably licensed for the features it is using—for example, the use of Active Session History (ASH), Automatic Workload Repository (AWR), and Automatic Database Diagnostic Monitor (ADDM) require a license for the Diagnostics Pack. Tip RDA is a wonderful way to instantly create documentation about a database system. You can use RDA on all the databases in your organization and tie them together with a simple HTML framework. Dictionary Tables and Views Not surprisingly, Oracle stores database metadata—data about data—in tables, just as in the case of user data. This collection of tables is owned by the user and is called the data dictionary. An example is the table, which stores information about all tables in the database. However, the information in these tables is kept very condensed for efficiency, and Oracle therefore provides a large number of views that are more suitable for querying. If you have DBA privileges, you will be able to query these views; an example is the view, also owned by . Familiarity with these views is the hallmark of a competent database administrator. Table 9-1 lists a few of the better- known views. A complete list can be found in Oracle Database 11g Reference along with detailed explanations. Listing 9-3 shows the columns of the table as well as the corresponding view. It also shows the actual definition of the view as listed in the view. Table 9-1. Well- Known Dictionary Views Name Description Information about all users of the database Descriptions of each tablespace Descriptions of each data file in each tablespace Descriptions of each index in the database Descriptions of each column of each index Descriptions of each table in the database Descriptions of each column of each table Descriptions of each view in the database
