ORA-600 17182导致oracle异常

发表于 2018 年 5 月 22 日 由 惜分飞

正常运行的数据库突然爆ORA-00600 17182,然后直接crash,以前遇到过类似的case:分享一例由于主库逻辑坏块导致dataguard容灾失效,这又是一例数据库正常crash之后无法启动成功的case

通过对于启动过程的观察,比较明显,由于数据库无法正常回滚,导致smon进程异常,从而使得数据库无法启动成功.恢复方法比较简单,就是对异常事务进行提交或者跳过即可

truncate IDL_UB1$恢复

发表于 2018 年 5 月 20 日 由 惜分飞

世界之大无奇不有,已经记不清这是第几个客户咨询IDL_UB1$ 被truncate之后导致数据库无法启动的case了.idl_ub1$表是用来存储PL/SQL的代码单元的，包括DIANA等，IDL在这里代表Interface Definition Language. 在数据库的启动过程中通过10046跟踪可以知道,有类似:select /*+ index(idl_ub1$ i_idl_ub11) +*/ piece#,length,piece from idl_ub1$ where obj#=:1 and part=:2 and version=:3 order by piece#的查询语句,由于该表被truncate之后,导致数据库启动无法绕过该sql,而hang住无法完全open成功.下午闲着没事通过模拟,可以对该故障实现正常open,并且导出数据
模拟业务数据

create user xff identified by oracle;
grant dba to xff;
conn xff/oracle
create table t_xifenfei as select * from dba_objects;
create index i_xifenfei on t_xifenfei(object_id);
create view v_xifenfei as select * from t_xifenfei;
create or replace procedure proc1(
para1 varchar2,
para2 out varchar2,
para3 in out varchar2
) as
v_name varchar2(20);
begin
 v_name :='xifenfei';
 para3 := v_name;
dbms_output.put_line('para3:'||para3);
end;

alter system checkpoint;

这类问题比较明显,正常方法无法打开,通过工具分析system文件,发现虽然truncate IDL_UB1$操作报错了,但是IDL_UB1$和对应的index I_IDL_UB11 obj#,dataobj#均已经改变,而且相关对象的segment header也变化为新dataobj#(truncate之后的),也就是说truncate在数据库中的主要更改操作已经完成.现在在缺少记录的情况下,数据库执行如下sql无法获取记录,从而无法open

通过对数据库采用技术欺骗手段,让数据库启动相关sql能够获取到记录(和正常查询的相同),从而实现数据库正常open

SQL> startup mount
ORACLE instance started.

SQL> alter database open;

Database altered.

open成功之后,后台报大量的ORA-08103: object no longer exists,通过分析是由于truncate IDL_UB1$没有完全成功,导致出现该错误.解决方法就是对Oracle数据字典进行人工更新,把没有完成的truncate操作在数据库中给予完成.
导出数据
exp导出数据成功
exp-data

但是expdp无法执行

[oracle@bogon oradata]$ expdp '"/ as sysdba"' schemas=xff file=1.dmp

暂时未去研究对这个表进行重建,使用exp导出然后再imp导入是比较理想的办法

恶意删除bootstrap$导致数据库无法正常启动

发表于 2018 年 5 月 19 日 由 惜分飞

有客户10.2.0.5的数据库关闭之后,无法正常启动报ORA-00704 ORA-00702错误.使用自研的ORA-702_Recovery Tool小工具可以实现一键恢复,下载地址：ORA-702_Recovery下载

根据以前恢复经验ORA-00702: bootstrap verison ” inconsistent with version ’8.0.0.0.0′,很可能是由于bootstrap$表异常了.
通过dbv检查system文件确认没有坏块
dbv-system

通过bbed分析,确认记录被删除
把数据文件拷贝到本地,通过bbed进行分析,确认记录丢失

故障原因跟踪
有人在数据库中注入了恶意脚本，导致数据库删除了bootstrap$中数据,关闭之后无法正常启动
delete-bootstrap$

处理方法
通过oracle bbed 修复数据字典,正常启动数据库
