In this post, we are gonna have look on some important views of Oracle Database.
The follow v$ views are used by the new 11g result cache:
v$result_cache_statistics v$result_cache_memory v$result_cache_objects v$result_cache_dependency v$client_result_cache_stats
The Oracle 11g RAT suite includes database replay and the following v$ view provides details on usage and status for this key new 11g feature with Oracle.

Oracle 11g RAC and ASM, Oracle 11g Data Guard and 11g Streams
Oracle 11g RAC and ASM provide highly available robust architectures for performance, service and reliability as part of the Oracle Maximum Availability Architecture (MAA). The following v$ views provide details on these key HA technologies.

Performance Tuning Oracle 11g
Performance tuning is a complex task that daunts many Oracle DBAs. It is as much an art as a science. While GUI tools such as Oracle Enterprise Manager and Quest TOAD provide a nice slick graphical interface, to dig into the internal nuts and bolts of database performance, the serious Oracle performance analyst relies on reports generated by v$ dynamic performance views from within the Oracle 11g data dictionary. The following v$ views provide insight into database tuning for Oracle 11g.
Wait Events for 11g
v$session v$waitclassmetric v$waitclassmetric_history v$waitstat v$wait_chains
