Oracle9i Database Reference Release 1 (9.0.1) Part Number A90190-02 |
|
SQL Scripts, 2 of 6
Oracle automatically creates the data dictionary when you create a database. Thereafter, whenever the database is in operation, Oracle updates the data dictionary in response to every DDL statement.
The data dictionary base tables are the first objects created in any Oracle database. They are created in the SYSTEM
tablespace and must remain there. The data dictionary base tables store information about all user-defined objects in the database.
Table 5-1 lists required scripts, which are run automatically when you create a database. They are described here because you might need to run them again when migrating or upgrading to a new release of Oracle. To run these scripts, you must be connected to Oracle as user SYS
.
