database - 无法在 SysAux 中恢复损坏的 Oracle 数据文件块

Question

Suse 9.1 上的 Oracle 10g

我正在照顾一个 Oracle 数据库。我有很好的 SQL 技能，但我不是 DBA，（我很难向不懂 IT 的老板解释工作角色的差异！）我知道足以让 Oracle 启动并运行，并将它的“自动”选项落实到位备份和优化，然后我就不用管它了。我从谷歌大学知道的一切！

我最近发现我们的生产数据库没有运行它的每日备份。它已经启动了一个然后挂起并且没有报告任何问题，因此没有立即注意到它。（备份作业挂起，而不是 oracle 实例。）

我已经杀死了备份，（它被卡在停止挂起，所以我最后不得不强制它退出），我想运行一个新的备份计划，但目前我收到了一个损坏的块警告。我尝试使用 blockrecover 修复它，但我得到 RMAN-06023: no backup or copy of datafile found to restore。运行交叉检查说文件可用。

损坏的块位于 SYSAUX 表空间数据文件中。如果我使数据库脱机，我可以删除并重新创建此数据文件还是会损坏数据库？（我现在让数据库离线我很紧张，因为我不知道它是否会恢复！）

谢谢你的帮助。以下是我的恢复尝试的输出...

检查完成时间。从 2009 年 1 月 13 日到 2009 年 3 月 24 日，您每天都有一个文件。从此，纳达。因此，RMAN 所告诉的是它在过去六个月中找不到数据文件 3 的任何备份。

不要恐慌。

你的数据库有多大？做出口可行吗？可能有一个更简单的解决方案，但如果您可以获取数据，则可以选择重新创建数据库。

根据文档，可以删除 SYSAUX 表空间。详细信息如下。

删除和重新创建 SYSAUX 表空间不适合胆小的人。我承认这是我第一次尝试。现在我被这个阻碍了：

SQL> drop tablespace sysaux including contents and datafiles
  2  /
drop tablespace sysaux including contents and datafiles
*
ERROR at line 1:
ORA-29857: domain indexes and/or secondary objects exist in the tablespace


SQL> drop index xdb.xdb$acl_xidx force;
drop index xdb.xdb$acl_xidx force
*
ERROR at line 1:
ORA-29868: cannot issue DDL on a domain index marked as LOADING


SQL>

这是一个路障。 DROP INDEX FORCE应该是 ORA-29868 的解决方法，所以我很高兴看到该消息。无论如何，一旦我越过这座山，我预计还会有其他人。它不认为这是一个整洁的过程。但是，公平地说，这根本不是我们应该做的事情。

因此，您可以进行导出是个好消息，因为我非常担心重新创建数据库是您最好的选择。祝你好运。

哦，一旦你解决了这种情况，就让你的老板知道雇佣 DBA 的紧迫性（或者让你接受适当的培训，如果你愿意的话）。

最后，这对你来说是一个很好的教导。第一次进行还原时，我发现以前的 DBA 没有启用ARCHIVELOG模式，我也没有检查。我的惩罚是拜访所有用户并告知他们他们失去了一天的工作。道德是，没有经过测试的备份是不存在的。

您对数据文件 3 的最新备份来自 2009 年 3 月 24 日。我认为您没有足够的存档将数据文件恢复到 25 SEP 09。据我所知，您不能删除并重新创建 SYSAUX 表空间。它包含与选项和功能相关的数据，例如 OLAP、文本、Ultra Search、Intermedia、Spatial、Workspace、Data Mining、EM Repository、Streams、LogMiner、Logical Standby、Statspack、Job Scheduler。如果您有 Oracle 支持，我会从他们那里得到帮助。我会尝试尽快对应用程序模式进行导出或 expdp。要获得某种数据备份，我怀疑您目前没有可恢复的备份。

我忘了，APC 是对的：不要惊慌。
