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
SQL> select dbms_utility.data_block_address_block(4194432) "blick",2 dbms_utility.data_block_address_file(4194432) "file" from dual;blick file---------- ----------128 1

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
