VC Appliance停机是用待机方式将Oracle数据库停了。再启动时,Oracle不能启动。用SQLPLUS中的Starup命令。出现下面的提示:

例子2之解决ORA

由于ORA-03113错误是一个通用的错误提示,能给的信息量很少。

于是一步步的来Debug,由于startup相当于3个命令的集合,就一步步地执行

先执行

SQL>startup nomount

并没有发现什么明显的失败信息,说明启动数据库实例是没有问题的,再执行第二步

SQL>alter database mount;

出现故障

例子2之解决ORA

看来故障出现在挂载数据库文件时,这一步骤主要是“允许特定的维护操作, 例如, 重命名数据文件, 添加, 删除或重命名重做日志文件, 启用和禁用重做归档选项, 执行完全数据库恢复。它不允许对数据库进行一般的访问。”

找到$ORACLE_HOME/rdbms/log目录,用ls -ltr找到最近的日志文件。在本例中是sales_ora_27010.trc

例子2之解决ORA

看来是olr.loc和ocr.loc两个文件不能打开。但是我的机器上根本没有这个文件。在网上搜索,发现这两个文件和Oracle的集群有关,我这里是单节点的,按说是不需要Oracle Local Registry的。

在网上搜索,也没有什么特别有用的提示,但是发现了另一个问题,就是我找的日志文件可能不对,找了原来安装时导出的备份虚拟机,用命令

SQL>show parameter background

找到正确的日志路径/usr/local/oracle/diag/rdbms/oracle/sales/trace

查看启动时的日志,在最后发现

LICENSE_SESSIONS_WARNING = 0

ALTER DATABASE   MOUNT

重试了多次,结果大多类似。在日志相同目录里,找到最近的trc文件,发现如下内容:

[root@localhost trace]# vi sales_ora_20498.trc

从上面来看,是控制文件故障。

现在重建控制文件,先到日志文件中找到一个相关参数的例子,在alert_sales.log文件中找出

然后,根据网上“如何获得创建控制文件脚本并创建脚本”一文中的脚本模板

在上面脚本中,我重试了几次,一次是日志大小,我想改成10M,但是不成功,另一次是提示temp01.dbf不是有效的数据库文件,我只有把它注释掉了,只能参照网上的脚本,一步步运行

例子2之解决ORA

其中,最后一句

ALTER TABLESPACE TEMP ADD TEMPFILE ‘/usr/local/oradata/ora11g/ORA11G/oracle/temp01.dbf’ SIZE 20480K REUSE AUTOEXTEND ON NEXT 640K MAXSIZE UNLIMITED

我也是从日志文件中找出来的。

根据上面显示的结果,应该是恢复成功了。

先重启操作系统。再手工启动Oracle,一切正常,但是对应的VCSA却不能启动,用OEM进去看到有数据块错误

例子2之解决ORA

从图中可以看到,ORA-01578错误,出现文件损坏,Block是45953。

用dbv命令检查文件

[oracle@localhost ~]$ dbv FILE=’/usr/local/oradata/ora11g/ORA11G/oracle/vpx01.dbf’ BLOCKSIZE=8192

得到下面的结果:

例子2之解决ORA

从中可以看出,被标记会Corrupt的块有452个。

再查询是哪些损坏的哪些内容:

Select tablespace_name,segment_type,owner,segment_name From dba_extents Where file_id=5 and 45953 between block_id and block_id+blocks-1;

结果如下:

例子2之解决ORA

说明损坏的是LOBSEGMENT

用命令找到损坏的表名和列名

select table_name, column_name from dba_lobs where segment_name=’SYS_LOB0000075100C00016$$’ and owner =’VPXADMIN’;

结果为:

例子2之解决ORA

select count(*) from VPXADMIN.VPX_RESOURCE_POOL;

发现这个表中只有8行数据。

ROWID                      ID

—————— ———-

AAASVcAAFAAACfjAAA          8

AAASVcAAFAAACfkAAB        523

AAASVcAAFAAACfkAAA        816

AAASVcAAFAAACfkAAC        826

AAASVcAAFAAACfkAAD        833

AAASVcAAFAAACfkAAE        839

AAASVcAAFAAACflAAB       1212

AAASVcAAFAAACfjAAC       1601

一行一行地试

select * from VPXADMIN.VPX_RESOURCE_POOL where id>1212;

发现ID=1212的这条记录是损坏的。

delete  from  VPXADMIN.VPX_RESOURCE_POOL where id=1212;

删除后,这个表可以正常地访问了,用DBV检查,结果没有什么不同。

shutdown immadiate数据库,提示没有Commit,看来删除并没有真正成功,于是在SQL命令行下,直接输入commit提交了修改。然后可以关闭数据库了。重启数据库DBV检查情况并无改观,说明这些还不够。

想了半天,也没有什么头绪,回到OEM页面中,在“可用 性”里面,选择了“执行恢复”,看看能不能将表空间VPX恢复到8月3日之前。

点了半天后,提示操作失败,同时VPX也脱机了,在图形界面中却怎么为无法联机。真是事情越搞越乱,好在问题并不复杂,在SQL环境下,执行

recover datafile 5

alter database datafile 5 online;

alter tablespace VPX online;

就可以联机了。

再回到原来的问题。

排查到现在,还有两个方向研究,一个是从vCenter服务器不能启动服务入手,查看日志,查看出错的地点和原因。一个还是从DBV出的错误结果入手。

先从DBV入手,在网上搜索到这篇文章,发现,可能根据DBV出的错误信息找到出错的文件和块,从而找到对应的表。

下面一部分的DBV 201错误块信息

DBV-00201: Block, DBA 21044390, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044391, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044393, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044394, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044395, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044397, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044398, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044399, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044401, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044402, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044403, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044406, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044407, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044410, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044411, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044412, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044414, marked corrupt for invalid redo application

DBV-00201: Block, DBA 21044415, marked corrupt for invalid redo application

根据最后的显示,应该有452个块,这里这是一部分,因为终端显示不完全。

拿最后一个来测试一下

select dbms_utility.data_block_address_file(21044415) from dual;

select dbms_utility.data_block_address_block(21044415) from dual;

结果是File为5,Block为72895。再用

Select tablespace_name,segment_type,owner,segment_name From dba_extents Where file_id=5 and 72895 between block_id and block_id+blocks-1;

得到Segment名为SYS_LOB0000075068C00059$$用

select table_name, column_name from dba_lobs where segment_name=’SYS_LOB0000075068C00059$$’ and owner =’VPXADMIN’

得到表名为VPX_HOST,列表为RESOURCE_INFO,测试一下:

例子2之解决ORA

这里又出现了一个块10309,用相同的方法找到是VPX_HOST表中的另一个列CAPABILITY,这种方法很明显能找到故障表,但是对于修复却帮助不大,因为数量太大,没有办法手工处理。

按上文中提到的修复方法先创一个表

create table corrupted_data (corrupted_rowid rowid);

然后,在SQL提示符下粘贴下面脚本代码,最后用/结束并运行。

set concat off

declare

error_1578 exception;

pragma exception_init(error_1578,-1578);

n number;

begin

for cursor_lob in (select rowid r, &&lob_column from &table_owner.&table_with_lob) loop

begin

n:=dbms_lob.instr(cursor_lob.&&lob_column,hextoraw(’889911′));

exception

when error_1578 then

insert into corrupted_data values (cursor_lob.r);

commit;

end;

end loop;

end;

根据提示符,输入需要的各变量值,列名为RESOURCE_INFO,所有者VPXADMIN,表名为VPX_HOST。脚本会把有问题行的ROWID写到上表创建的表中。上面的代码中hextoraw(’889911′)有点奇怪,不知道是什么意思,在上文最后到是提到了,原来这个值是随便写的,主要是让n总是返回0值。

然后再将有问题行中的对应列数据填为空值。

set concat off

update &table_owner.&table_with_lob set &lob_column=empty_blob() where rowid in (select corrupted_rowid from corrupted_data);

出现下面的错误提示

ORA-00932: inconsistent datatypes: expected NCLOB got BLOB

于是将上面的代码修改成

update &table_owner.&table_with_lob set &lob_column=empty_clob() where rowid in (select corrupted_rowid from corrupted_data);

再试一次,Update成功。(如果类型是XMLTYPE则用XMLType.createXML(”)代替empty_clob()。)

回到命令行方式,用DBV再试一次,结果却仍是有452个Page被标记为坏。

但是这次用Select * from vpxadmin.vpx_host;能返回正常的值了。说明表的确是被修复了。但量DBV结果仍标记为Corrupted,用DBV来找坏表的实用性就差了许多。像这样有452个坏块,一个一个地测试,太麻烦了。

转到vCenter的服务器中,

例子2之解决ORA

发现在启动过程中,初始化VPXD时出错。

查看/var/log/vmware/vpx目录下的日志。大致可判断为数据库中数据读出来后,反序列化出错。但是因为上面的原因我又找到不出故障的表的内容,用OEM在表空间里试了几个表,都是好的,从VCenter日志中也找不出线索,问题就变成死问题了。

看来只能重建一个表空间给vCenter用,原来保留的数据也只有放弃了。
