从 Oracle Copilot 恢复点或即时访问装入一步还原到 ASM 存储

以下步骤介绍如何使用 RMAN 从恢复点进行还原。只有当运行了 nborair -create_recovery_point 命令并在目标客户端装入了此恢复点之后，才可执行此步骤。

注意:

GUI 不提供一步还原到 ASM 存储的功能。只能使用 RMAN 运行此功能。

此步骤示例假定已装入恢复点，并以装入点 /db_mp 为例。所有 RMAN 命令都必须从目标主机运行。

从恢复点一步还原到 ASM 存储

从恢复点对备份进行编录。

RMAN> catalog start with '/db_mp/';

searching for all files that match the pattern /db_mp/

从恢复点的时间点还原数据文件。

以下示例将从磁盘 (DISK) 进行 RMAN 还原。此外，此示例还会使用 NLS_DATE_FORMAT="DD-MM-YYYY-HH24:MI:SS" 命令，此命令是在运行 RMAN 之前在环境中设置的。请使用适用于您环境的日期格式。

恢复数据库。

如果无法从磁盘还原存档日志，则这些日志将从 NetBackup (sbt_tape) 进行还原。
