Oracle 视图 DBA_HIST_PDB_IN_SNAP 官方解释，作用，如何使用详细说明

本站中文解释

-新镜像片

Oracle 视图 DBA_HIST_PDB_IN_SNAP 查看每一个快照中包含哪一个pluggable database（可插拔数据库）。它会显示每一个快照的PBD ID以及相应的时间。它还提供了Auto Service Request（ASR）的ID。使用特定的ASR ID，数据库管理员可以指定要使用的特定镜像片。

使用方法：

1. 首先，在Oracle终端中输入以下命令，以查看DBA_HIST_PDB_IN_SNAP视图：

SELECT * FROM DBA_HIST_PDB_IN_SNAP;

2. 使用ASR_ID过滤结果，以查看特定镜像片中包含的PDB：

SELECT * FROM DBA_HIST_PDB_IN_SNAP WHERE ASR_ID = ‘12345’;
