ORA-06502/ORA-06512错误

AWR LOAD
~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~  This script will load the AWR data from a dump file. The   ~
~  script will prompt users for the following information:    ~
~     (1) name of directory object                            ~
~     (2) name of dump file                                   ~
~     (3) staging schema name to load AWR data into           ~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Specify the Directory Name
~~~~~~~~~~~~~~~~~~~~~~~~~~

Directory Name                 Directory Path

XMLDIR                         /u01/oracle/oracle/product/11.2.0/db_1/rdbms/xml

Choose a Directory Name from the list above (case-sensitive).

Enter value for directory_name: DATA_PUMP_DIR

Using the dump directory: DATA_PUMP_DIR

Specify the Name of the Dump File to Load
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Please specify the prefix of the dump file (.dmp) to load:

Enter value for file_name: awrdat_70441_70885-vpos-primary

Loading from the file name: awrdat_70441_70885-vpos-primary.dmp
begin

ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 2

因为导出来的awr数据库的编码是AL32UTF8,而现在的编码是ZHS16GBK,所以解决方法是设置NLS_LANG为合适编码

[oracle@xifenfei ~]$ env|grep NLS_LANG
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
[oracle@xifenfei ~]$ export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

ORA-31640

这里我们可以看到,dmp文件名为31个字符，而在提示文件名的时候是30个字符，从而出现了dmp文件不存在而导致的相关错误，解决方案重命名dmp文件，名称不超过30个字符

--------------------- Binary Stack Dump ---------------------

通过这个trace的部分信息可以得到:
1.操作系统版本AIX x64(5.3)
2.数据库版本10.2.0.4
3.sql语句调用EXTRACTVALUE函数
4.Call Stack Trace信息

查询MOS[ID 467350.1]发现匹配信息

Cause
Bug 6030982 ORA-600 [QMXTRICHECKANDREWRITEQB0] WITH QUERY USING EXTRACTVALUE FUNCTION

Solution
This bug is going to be fixed in furture 10.2.0.5.0 and 11g
At the mean time , user can workaround by 

set
event = "19027 trace name context forever, level 1"
within init.ora or spfile file then bounce database.

or

SQL> alter session set events ='19027 trace name context forever, level 1';
SQL> Alter system flush shared_pool;
-- Execute affected query

通过mos可以确定:
1.是因为数据库执行EXTRACTVALUE函数遇到该bug
2.在11g和10.2.0.5中修复该bug
3.可以通过设置event = “19027 trace name context forever, level 1″来临时解决该问题

个人处理建议
1.如果数据库方便升级,那建议升级处理
2.如果数据库不便立马升级,建议在业务低估时设置session event 19027,然后 flush shared_pool,执行报错sql,如果问题解决,在合适时间设置system event来临时屏蔽该问题.

数据文件的CREATION_TIME来源和算法

发表于 2012 年 11 月 12 日 由 惜分飞

对ORACLE比较熟悉的人都知道v$datafile.CREATION_TIME和v$datafile_header.CREATION_TIME这两个列都是表示数据文件的创建时间,而根据我们的经验可以知道几点:
1.当v$datafile.CREATION_TIME与v$datafile_header.CREATION_TIME不一致时数据库不能正常启动
2.v$datafile.CREATION_TIME的值来源于v$datafile_header.CREATION_TIME
3.而v$datafile_header.CREATION_TIME的值来源于数据文件头的块中的信息
现在就出现一个问题,数据块中的kcvfhcrt是一个16进制的数,如何实现在v$datafile和v$datafile_header中转为为了数据文件创建的日期
数据文件中存储创建数据文件日期内容

ub4 kcvfhcrt                             @108      0x2c67319c

v$datafile.CREATION_TIME值

SQL> select to_char(CREATION_TIME,'yyyy-mm-dd hh24:mi:ss') xifenfei 
   2 from v$datafile where file#=1;

如何通过kcvfhcrt值推算出来CREATION_TIME或者通过CREATION_TIME推断出来kcvfhcrt的值规则:
熟悉数据库SCN计数原理的人都知道,我们现在使用的数据库是从1988/01/01 00:00:00开始记录SCN,也就是说我们的数据库的使用最早时间只能是从1988年元旦凌晨开始，那么也就是说数据库记录的创建时间可以采用这个时间点为起点,然后每增加一秒,数据库的kcvfhcrt就增加1,但是ORACLE为了计算简便,每个月按照31天计算
通过时间推算出来kcvfhcrt值

--数据库记录时间起点
1988/01/01 00:00:00
--当前数据文件创建日志
2011/03/05 05:26:52
--两者相差时间
23年02月04日05时26分52秒
--计算相差秒
23*12*31*24*60*60+2*31*24*60*60+4*24*60*60+5*60*60+26*60+52=744960412
--kcvfhcrt值转换
2c67319c(16进制)=744960412(10进制)

通过kcvfhcrt计算CREATION_TIME值

SQL> select to_number('2c67319c','xxxxxxxxxxx') from dual;

TO_NUMBER('2C67319C','XXXXXXXXXXX')
-----------------------------------
                          744960412

SQL> select 744960412/(12*31*24*60*60) from dual;

744960412/(12*31*24*60*60)
--------------------------
                23.1780295

SQL> select mod(744960412,(12*31*24*60*60)) from dual;

MOD(744960412,(12*31*24*60*60))
-------------------------------
                        5722012


SQL> select 5722012/(31*24*60*60) from dual;

5722012/(31*24*60*60)
---------------------
           2.13635454

SQL> select mod(5722012,(31*24*60*60)) from dual;

MOD(5722012,(31*24*60*60))
--------------------------
                    365212

SQL> select 365212/(24*60*60) from dual;

365212/(24*60*60)
-----------------
       4.22699074

SQL> select mod(365212,(24*60*60)) from dual;

MOD(365212,(24*60*60))
----------------------
                 19612

SQL> select 19612/(60*60) from dual;

19612/(60*60)
-------------
   5.44777778

SQL> select mod(19612,(60*60)) from dual;

MOD(19612,(60*60))
------------------
              1612

SQL> select 1612/60 from dual;

   1612/60
----------
26.8666667

SQL> select mod(1612,60) from dual;

MOD(1612,60)
------------
          52

从这里可以得出23年2月4天5时26分52秒，与1988年01月01日00时00分00秒相加得到
2011年03月05日 5:26:52

SQL> select to_char(CREATION_TIME,'yyyy-mm-dd hh24:mi:ss') from v$datafile where file#=1;

TO_CHAR(CREATION_TI
