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。

官方英文解释

V$PROXY_COPY_DETAILS contains information about all available control file and datafile proxy copies.

Name of the media on which the copy resides. This value is informational only. It is not needed for restore.

Media pool in which the copy resides. This is the same value that was entered in the POOL operand of the Recovery Manager BACKUP command.

Indicates whether this backup set has a retention policy that is different than the value for the configure retention policy (YES) or not (NO)

If specified, then this is the date after which the backup becomes obsolete. If this column is NULL, then the backup never expires.

LOGS Indicates a long-term backup made with the LOGS keyword, which is now deprecated

BACKUP_LOGS Indicates that the backup was made in open mode, so archived log backups must be applied to make it consistent

NULL Indicates that this backup has no KEEP options and becomes obsolete based on the retention policy

0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.
