三.分析日志
ORA-00600[2662]主要参数说明见:ORA-00600 [2662]
这里补充说明:e表示出现异常问题的数据块的DBA,这里的4194432就是一个数据块的DBA

--通过DBA地址查询数据块和文件号

四.bbed查看相关SCN

这里看到的SCN(16进制)和我们在alert日志中看到的有一定的出入原因是在数据库启动的时候，当前SCN增加了，但是因为数据库直接abort，没有写入到数据文件中。导致数据文件头部的SCN比alert中显示的稍微小一点(还有可能，系统当前的scn比system01.dbf的scn大一点)。通过对比数据块和数据文件头部的SCN也可以说明当数据块的SCN>数据块当前SCN导致ORA-00600[2662]

七.补充说明
一般遇到ORA-00600[2662]都是使用alter session set events ‘10015 trace name adjust_scn level N’;方法处理，但是有时候会遇到ORA-01031错误，那就需要请bbed帮忙处理

One thought on “使用bbed解决ORA-00600[2662]”

  1. 通过dba查看file#,block总结

    --10进制dba
select dbms_utility.data_block_address_block(4194432) &quot;blick&quot;,
 dbms_utility.data_block_address_file(4194432) &quot;file&quot; from dual;
--16进制
set serveroutput on
declare
   p_dba   VARCHAR2 (255) :='0x00800212';
   l_str   VARCHAR2 (255) DEFAULT NULL;
BEGIN
    l_str :=
         'datafile# is:'
      || DBMS_UTILITY.data_block_address_file (TO_NUMBER (LTRIM (p_dba, '0x'),'xxxxxxxx'))
      || chr(10)||'datablock is:'
      || DBMS_UTILITY.data_block_address_block (TO_NUMBER (LTRIM (p_dba, '0x'),'xxxxxxxx'));
   dbms_output.put_line(l_str);
END;

    10/16进制互转

    --10 to 16
select to_char(2147510731,'xxxxxxxxxxx') from dual;
--16 to 10
select to_number('800069c8','xxxxxxxxxxx') from dual;
