概念
Active DUPLICATE uses a network-enabled restore method that is run on the auxiliary database to clone the source database. This is in contrast to the image copy-based approach that was run on the source database in previous releases. Active DUPLICATE supports the SECTION SIZE option to divide data files into subsections that are restored in parallel across multiple channels on the auxiliary database. Active DUPLICATE supports compression during the restore phase.
Active DUPLICATE使用在辅助数据库上运行的支持网络的恢复方法来克隆源数据库。这与之前版本中在源数据库上运行的基于图像的基于映像的方法形成了对比。Active DUPLICATE支持SECTION SIZE选项，将数据文件划分为在辅助数据库的多个通道上并行恢复的子部分。在恢复阶段，主动复制支持压缩
The benefits of this new feature include:
新特性的优点：
• Reduce active duplicate time for databases with large data files by more evenly spreading out the restore workload across multiple channels on the auxiliary database.
通过在auxiliary database.的多个通道上更均匀地分布恢复工作负载，减少数据库与大数据文件的重复时间
• Reduce active duplicate time by more efficiently using network bandwidth using compression during data transfer operations.
利用网络带宽减少复制的时间
In active database duplication, RMAN connects as TARGET to the source database instance and as AUXILIARY to the auxiliary instance. RMAN then manages the copying of the database to the auxiliary instance over the network. No backups of the source database are required.
RMAN can transfer the files required for active database duplication as image copies or backup sets.
在active database复制中，RMAN将目标连接到源数据库实例，并作为auxiliary instance的辅助对象。然后RMAN将数据库的复制管理到网络上的auxiliary instance。不需要对源数据库进行备份。
RMAN可以将active databas复制所需的文件作为映像副本或备份集传输。
When duplicating a whole CDB or one more PDBs:
• You must create the auxiliary instance as a CDB. To do so, start the instance with the following declaration in the initialization parameter file:
• •必须创建auxiliary instance作为CDB。为此，在初始化参数文件中使用以下声明启动实例:
• enable_pluggable_database=TRUE
• When instructed to connect to the necessary instances, connect to the root as a user with SYSDBA or SYSBACKUP privilege. On both instances, the password for the user performing the duplication must be the same.
•当指示连接到必要的实例时，以SYSDBA或SYSBACKUP特权连接到root用户。在这两个实例中，执行复制的用户的密码必须相同。
• When instructed to create an initialization parameter file for the auxiliary instance, you must copy the file from the source database. This ensures that the auxiliary instance is also a CDB. After copying, you modify DB_NAME and the various destination/location parameters
•当指示为auxiliary instance创建初始化参数文件时，必须从源数据库复制文件。这确保了辅助实例也是CDB。在复制之后，您可以修改DB_NAME和各种目的地/位置参数实验
