Oracle 视图 V$PROXY_COPY_DETAILS 官方解释，作用，如何使用详细说明

本站中文解释

Oracle视图V$PROXY_COPY_DETAILS用于获取数据库表空间中某种类型的数据文件被复制的进度以及拷贝状态等信息。 该视图仅在使用外部表空间进行镜像拷贝时有用。 它可以提供有关当前母体表空间中某些文件执行复制操作的信息，以及数据文件执行拷贝操作时的拷贝进度和状态的信息。

使用示例：

SELECT source_name, target_name, copy_status FROM V$PROXY_COPY_DETAILS WHERE dest_tablespace=’USERS_COPY’;

上面的示例查询将获取当前USER_COPY表空间中拷贝操作的源文件名称、目标文件名称以及拷贝状态。
