ORA-600(999)错误(二)

原创 Linux操作系统 作者:yangtingkun 时间:2007-04-18 00:00:00 0 删除 编辑

今天后台出现了很多ORA-600,其中第一个错误参数为999

这个问题在METALINK上没有找到类似的说明。

这篇进一步深入研究数据库中缺少了哪些信息造成了这个问题。

关于错误问题产生的原因参考:ORA-600(999)错误(一):http://yangtingkun.itpub.net/post/468/281181


上一篇文章简单讨论了为什么会出现这个问题。这里打算分析一下这个数据库缺少了哪些数据字典信息,导致了问题的产生。

首先,虽然Oracle缺少了部分信息,但是Oracle仍然认为这个对象是物化视图,而且物化视图的刷新一直都是正常的。

看来要寻找问题产生的原因首先必须从错误入手。

对于正常的物化视图表,OracleALTER TABLE RENAME时会报错,而对于这个数据库,则可以成功,说明在ALTER TABLE RENAME操作执行时,进行了某种检查。

寻找问题最简单的方法是进行SQL_TRACE,然后进行比较:

SQL> CREATE TABLE T_RENAME (ID NUMBER);

表已创建。

SQL> ALTER SESSION SET SQL_TRACE = TRUE;

会话已更改。

SQL> ALTER TABLE T_RENAME RENAME TO T_RENAMED;

表已更改。

SQL> ALTER SESSION SET SQL_TRACE = FALSE;

会话已更改。

SQL> DISC Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.4.0 - Production
断开

SQL> CONN TEST/TEST@TESTZJ
已连接。
SQL> DROP TABLE T_RENAMED;

表已删除。

SQL> ALTER SESSION SET SQL_TRACE = TRUE;

会话已更改。

SQL> ALTER TABLE MV_T RENAME TO T_MV;
ALTER TABLE MV_T RENAME TO T_MV
*
1 行出现错误:
ORA-32318: cannot rename a materialized view


SQL> ALTER SESSION SET SQL_TRACE = FALSE;

会话已更改。

将得到的两个TRACE信息进行比对:

显然,Oracle在执行完下面这个SQL后报错:

select ts#,file#,block#,nvl(bobj#,0),nvl(tab#,0),intcols,nvl(clucols,0),
audit$,flags,pctfree$,pctused$,initrans,maxtrans,rowcnt,blkcnt,empcnt,
avgspc,chncnt,avgrln,analyzetime, samplesize,cols,property,nvl(degree,1),
nvl(instances,1),avgspc_flb,flbcnt,kernelcols,nvl(trigflag, 0),
nvl(spare1,0),nvl(spare2,0),spare4,spare6
from tab$
where obj#=:1

说明Oracle的在执行完这个SQL后,就确定是否是物化视图了。

SQL> SELECT FLAGS,PROPERTY FROM TAB$ WHERE OBJ# IN (45549, 43031);

FLAGS PROPERTY
---------- ----------
1 536870912
262145 637534208

对比物化视图和普通表,去掉二者完全相同的信息,得到上面的结果。对于物化视图和表,只有FLAGSPROPERTY有所区别。

如果对数据字典信息比较熟悉,其实已经可以断定是PROPERTY字段包含了关键信息,如果不熟悉,也没有关系。

下面再进行诊断:找一个没有问题的物化视图对象和这个出现问题的站点的物化视图信息进行比较,看看问题出在哪里:

正常的物化视图:

SQL> SELECT FLAGS,PROPERTY FROM TAB$ WHERE OBJ# IN (46580);

FLAGS PROPERTY
---------- ----------
262673 637534208

而问题物化视图:

SQL> SELECT FLAGS,PROPERTY FROM TAB$ WHERE OBJ# IN (32907);

FLAGS PROPERTY
---------- ----------
262673 570425344

这下问题明显了,错误出现在PROPERTY字段。

SQL> SELECT 637534208-570425344 FROM DUAL;

637534208-570425344
-------------------
67108864

而丢失的这个67108864信息,正好是物化视图表的信息。可以参考DBA_LOGSTDBY_UNSUPPORTED视图的定义:

SQL> SELECT TEXT FROM DBA_VIEWS WHERE VIEW_NAME = 'DBA_LOGSTDBY_UNSUPPORTED';

视图定义中注释清晰的说明67108864是物化视图表信息。因此这就是导致这个问题产生的真正原因。在全库导入过程中,表的导入和物化视图导入是分开的,因此,Oracle丢失了表上的这个信息。导致了问题的产生。

因此,对于这种负责环境,还是建议采用迁移后重新建立的方式,采用全库EXP/IMP的方式很容易造成问题。
