本文介绍了Oracle数据库的多项新特性，包括应用连续性、Oracle Flex ASM、Oracle ASM磁盘擦除、基于策略的数据库增强、标准化部署和修补、动态IP管理和名称解析、IPv6支持等，这些特性显著提升了数据库的可用性和管理效率。

Application Continuity 以前版本failover仅支持查询操作，现在可以支持事务了。
Oracle Flex ASM: With this feature, database instances use remote ASM instances. RAC的DB实例和ASM实例不用一一对应了。
Oracle ASM Disk Scrubbing: Checks for logical data corruptions and repair them automatically.
Enhancements to Policy-based Databases: Actively utilizes different sized servers
What - if analysis for server pool management
Standardized deployment and patching: Introducing GHS, rapid home provisioning and gold images
A new "ghctl" command for better patching
Oracle Utility Cluster
Dynamic IP Management and name resolution made easy
IPv6 Based IP Addresses Support for client connectivity
Multi-purpose Installation
Oracle installer will run Fix-up scripts & "root.sh" scripts across nodes. You don't have to run the scripts manually on RAC nodes.
