This appendix provides the following reference information:

Oracle Label Security Data Dictionary Tables and Views

Oracle9i Data Dictionary Tables

Oracle Label Security does not in any way label the Oracle9i data dictionary tables. Access is controlled by standard Oracle9i system and object privileges. For a description of all data dictionary tables and views, see the Oracle9i Reference

Oracle Label Security Data Dictionary Views

Oracle Label Security maintains an independent set of data dictionary tables. These tables are exempt from any policy enforcement. This section lists the views which can display information related to Oracle Label Security.

Note that access to the DBA views is granted by default to the SELECT_CATALOG_ROLE, a standard Oracle9i role which lets you examine the Oracle9i data dictionary.

Oracle Label Security Auditing Views

Using the SA_AUDIT_ADMIN.CREATE_VIEW procedure, you can create an audit trail view for the specified policy. By default, this view is named DBA_policyname_AUDIT_TRAIL.

The DBA_SA_AUDIT_OPTIONS view contains the columns POLICY_NAME, USER_NAME, APY, SET_, and PRV.

Restrictions in Oracle Label Security

The following restrictions exist in this Oracle Label Security release:

CREATE TABLE AS SELECT Restriction in Oracle Label Security

If you attempt to perform CREATE TABLE AS SELECT in a schema which is protected by an Oracle Label Security policy, the statement will fail.

Label Tag Restriction

Label tags must be unique across all policies in the database. When you use multiple policies in a database, you cannot use the same numeric label tag in different policies.

Export Restriction in Oracle Label Security

The LBACSYS schema cannot be exported due to the use of opaque types in Oracle Label Security. To export an entire database, you must individually specify all of the schemas and/or tables (except for the LBACSYS schema). Use standard backup techniques to back up the LBACSYS schema.

Oracle Label Security Deinstallation Restriction

Do not perform a DROP USER CASCADE on the LBACSYS account.

Connect to the database as user SYS, using the AS SYSDBA syntax, and run the file $ORACLE_HOME/rdbms/admin/catnools.sql to deinstall Oracle Label Security.

Shared Schema Support

User accounts defined in the Oracle Internet Directory cannot be given individual Oracle Label Security authorizations. However, authorizations can be given to the shared schema to which the directory users are mapped.

The Oracle Label Security function SET_ACCESS_PROFILE can be used programmatically to set the label authorization profile to use after a user has been authenticated and mapped to a shared schema. Oracle Label Security does not enforce a mapping between users who are given label authorizations in Oracle Label Security and actual database users.

Hidden Columns Restriction

PL/SQL does not recognize references to hidden columns in tables. A compiler error will be generated.
