B SQL Scripts
This appendix describes SQL scripts that are required for optimal operation of the Oracle Database.
The SQL scripts are described in the following sections:
- Creating the Data Dictionary
- Creating Additional Data Dictionary Structures
- The "NO" Scripts
- Upgrade and Downgrade Scripts
- Java Scripts
Creating the Data Dictionary
When you use the Database Configuration Assistant to create a database, Oracle automatically creates the data dictionary. 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 B-1 lists required scripts, which are run automatically when you create a database using the Database Configuration Assistant. They are described here because you might need to run them if you create a database manually. To run these scripts, you must be connected to Oracle as a user with SYSDBA privileges.
Table B-1 Creating the Data Dictionary Scripts
| Script Name | Needed For | Description |
|---|---|---|
|
catalog.sql |
All databases |
Creates the data dictionary and public synonyms for many of its views Grants PUBLIC access to the synonyms |
|
catproc.sql |

|
catclust.sql |

Creating Additional Data Dictionary Structures
Oracle supplies other scripts that create additional structures you can use in managing your database and creating database applications. These scripts are listed in Table B-2.
See Also:
Your operating system-specific Oracle documentation for the exact names and locations of these scripts on your operating system
