1 Oracle Database 11g Release 2 (11.2.0.4) New FeaturesThis chapter contains descriptions of all of the features that are new to Oracle Database 11g Release 2 (11.2.0.4). 1.1 Oracle Data RedactionThis new database security feature is part of Oracle Advanced Security and prevents data columns (such as credit card numbers, U.S. Social Security numbers, and other sensitive or regulated data) from being displayed by applications. It is driven by declarative policies that can take into account database session factors and information passed by applications. Sensitive display data can be redacted at runtime on live production systems with minimal disruption to running applications and without altering the actual stored data. Different types of redaction are supported including full, partial, random, and regular expression redaction. You can conceal entire data values or redact only part of the value. The functionality is implemented inside of the database, therefore separate installation is not required. See Also: Oracle Database Advanced Security Administrator's Guide for details 1.2 Trace File Analyzer and CollectorThe Trace File Analyzer (TFA) and Collector, also known as TFA Collector, is a diagnostic collection utility to simplify diagnostic data collection on Oracle Clusterware, Oracle Grid Infrastructure and Oracle RAC systems. Unlike similar solutions, the TFA Collector optimizes data gathering by providing a single source of management as well as various focus levels. Data for a whole cluster can be gathered from one node using one command and can be stored on a central server for further analysis and processing. The TFA Collector also allows for trimming data collection by focusing on certain components or relevant time frames only.

It also includes checks for Oracle Clusterware, Oracle Automatic Storage Management (Oracle ASM) and Oracle Grid Infrastructure. RACcheck provides best practices recommedations considering the whole stack, including Maximum Availability Architecture (MAA) configurations and is therefore the ideal tool for regular health checks as well as pre- and post-upgrade best practices assessments.

Consolidated database replay supports scheduling of the individual replays enabling investigations of various scenarios (for example, what if all my individual workloads hit their peak utilizations at the same time). Consolidated replay provides the ability to test database performance for database consolidation projects, whether consolidating onto an Oracle database machine or other consolidated infrastructure.
