  • Oracle 12C 新特性之 恢复表

    RMAN的表级和表分区级恢复应用场景:

    1、You need to recover a very small number of tables to a particular point in time. In this situation, TSPITR is not the most effective solution because it moves all the objects in the tablespace to a specified point in time.
    2、You need to recover tables that have been logically corrupted or have been dropped and purged.
    3、Flashback Table is not possible because the desired point-in-time is older than available undo.
    4、You want to recover data that is lost after a DDL operation modified the structure of tables. Using Flashback Table is not possible because a DDL was run on the tables between the desired point in time and the current time. Flashback Table cannot rewind tables through structural changes such as a truncate table operation.

    译文:
    1、您需要将非常少量的表恢复到特定的时间点。在这种情况下,TSPITR 不是最有效的解决方案,因为它将表空间中的所有对象都移动到指定的时间点。
    2、您需要恢复已被逻辑损坏或已被删除和清除的表。
    3、Flashback Table 不可用,如undo 数据已经被覆盖。
    4、恢复在DDL操作修改表结构之后丢失的数据。使用Flashback表是不可能的,因为在需要的时间点和当前时间之间的表上运行一个DDL。闪回表不能通过诸如截断表操作之类的结构更改来倒表。

    RMAN的表级和表分区级恢复限制:
    1、Tables and table partitions belonging to SYS schema cannot be recovered.
    2、Tables and table partitions from SYSTEM and SYSAUX tablespaces cannot be recovered.
    3、Tables and table partitions on standby databases cannot be recovered.
    4、Tables with named NOT NULL constraints cannot be recovered with the REMAP option.

    RMAN的表级和表分区级恢复前提:
    1、The target database must be in read-write mode.
    2、The target database must be in ARCHIVELOG mode.
    3、You must have RMAN backups of the tables or table partitions as they existed at the point in time to which you want recover these objects.
    4、To recover single table partitions, the COMPATIBLE initialization parameter for target database must be set to 11.1.0 or higher.

    恢复方法:
    1、SCN
    2、Time
    3、Sequence number

    RMAN从备份中自动处理恢复表或者表分区时的步骤:

    1、Determines which backup contains the tables or table partitions that need to be recovered, based on the point in time specified for the recovery.
    2、Determines if there is sufficient space on the target host to create the auxiliary instance that will be used during the table or partition recovery process.
    If the required space is not available, then RMAN displays an error and exits the recovery operation.
    3、Creates an auxiliary database and recovers the specified tables or table partitions, until the specified point in time, into this auxiliary database.
    You can specify the location to which the recovered data files are stored in the auxiliary database.
    4、Creates a Data Pump export dump file that contains the recovered tables or table partitions.
    You can specify the name and the location of the export dump file used to store the metadata of the recovered tables or table partitions.
    5、(Optional) Imports the Data Pump export dump file into the target instance.
    You can choose not to import the export dump file that contains the recovered tables or table partitions into the target database. If you do not import the export dump file as part of the recovery process, you must manually import it later using the Data Pump Import utility.
    6、(Optional) Renames the recovered tables or table partitions in the target database.
    You can also import recovered objects into a tablespace or schema that is different from the one in which they originally existed.

    译:
    1.确定哪些备份包含需要恢复的表或表分区,根据指定的时间来进行恢复。
    2.确定目标主机上是否有足够的空间来创建将在表或分区恢复过程中使用的辅助实例。 如果需要的空间不足,那么RMAN会报错并退出恢复操作。
    3.创建一个辅助数据库并恢复指定的表或表分区,并根据指定的时间来恢复指定的表或表分区到辅助数据库中。 可以指定用于存储已恢复表或表分区的元数据的导出转储文件的名称和位置。
    4.创建一个数据泵导出转储文件,其中包含已恢复的表或表分区。可以指定用于存储已恢复表或表分区的元数据的导出转储文件的名称和位置。
    5. (可选操作)将上一步生产的数据泵文件导入到目标实例中。您可以选择不导入包含已恢复的表或表分区到目标数据库的导出转储文件。如果您不导入导出转储文件作为恢复过程的一部分,那么您必须在稍后使用 impdp 手工导入。
    6. (可选操作)在目标数据库中rename 恢复表或表分区。

    补充:恢复表不支持公共用户,开始作者使用的是公共用户做实验,报错如下,也没有很明显的提示,后换本地用户没有这类报错。

    恢复过程:还原system,undo,sysaux表空间,然后read only数据库,然后重启数据库还原表所在表空间,然后expdp导出表,根据需要决定是否导入表到原PDB数据库中,最后删除辅助数据库。 整个过程对原PDB没有影响。
