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

错误比较明显由于file 609 block 6异常，导致smon无法进行回滚,从使得数据库open之后,立马crash.这个问题可以通过使用bbed修复坏块解决,也可以通过设置合适的参数和事件,禁止smon的一些操作来规避
bbed修复block之后dbv检查

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

通过这里发现，数据库启动执行select line#, sql_text from bootstrap$ where obj# != :1然后报ORA-07445 lmebucp错误。这样的错误比较诡异,一般可能是由于bootstrap异常导致,但是这里再往上跟踪发现 create bootstrap$表指定的记录为file 1 block 257,根据经验知道数据库的bootstrap$表记录一般是377 或者520比较常见.通过工具对于file 1进行分析

DUL> dump datafile 1 block 257

发现异常比较明显,block 257为data_object_id=41,也就是
41|41|CREATE UNIQUE INDEX I_FILE1 ON FILE$(FILE#) PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE ( INITIAL 64K NEXT 1024K MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 OBJNO 41 EXTENTS (FILE 1 BLOCK 257))
这里看数据库的引导异常或者bootstrap$表中记录异常.通过修复bootstrap相关内容,数据库完美启动
