C.4 Support For Row-level Security and Fine-Grained Auditing → As of Oracle Database 11 g, Logical Standby can automatically replicate the security environment provided through the DBMS_RLS and DBMS_FGA PL/SQL packages. This support simplifies management of security considerations when a server fails over to the standby since the security environment will transparently be maintained. It also ensures that access control policies applied to the primary data can
C.4.2 Fine-Grained Auditing → Fine-grained auditing provides a way to audit select statements. The DBMS_FGA package enables all select statements that access a table to be captured, together with what data was accessed. An FGA policy may be applied to a particular column or even to only those select statements that return rows for which a specified predicate returns TRUE. When a DBMS_FGA procedure is executed on the primary, additional

C.11.2 Replication of AUD$ and FGA_LOG$ on Logical Standbys → Auditing and fine-grained auditing are supported on logical standbys. Changes made to the AUD$ and FGA_AUD$ tables at the primary database are replicated at the logical standby. Both the AUD$ table and the FGA_AUD$ table have a DBID column. If the DBID value is that of the primary database, then the row was replicated to the logical standby based on activities at the primary. If the DBID value is

C.8.2 Unsupported PL/SQL Supplied Packages → Oracle PL/SQL supplied packages that modify system metadata typically are not supported by SQL Apply, and therefore their effects are not visible on the logical standby database. Examples of such packages are DBMS_JAVA, DBMS_REGISTRY, DBMS_ALERT, DBMS_SPACE_ADMIN, DBMS_REFRESH, DBMS_REDEFINITION, and DBMS_AQ. Specific support for DBMS_JOB has been provided. Job execution is suspended on a logical
C.2 Support for Transparent Data Encryption (TDE) → Data Guard SQL Apply can be used to provide data protection for a primary database with Transparent Data Encryption (TDE) enabled. Consider the following when using a logical standby database to provide data protection for applications with advanced security requirements: Tables with Transparent Data Encryption using server held keys are supported in the context of a logical standby database when
