ORA-00227: corrupt block detected in control file---惜分飞

由于服务器断电，导致oracle数据库无法正常启动，recover报ORA-00353 ORA-00312错

SQL> recover datafile 1; ORA-00283: recovery session canceled due to errors ORA-00368: checksum error in redo log block ORA-00353: log corruption near block 8 change 237896529 time 12/03/2024 22:03:32 ORA-00312: online log 1 thread 1: 'E:\ORADATA\xifenfei\REDO01.LOG'

报错提示比较明显,是由于oracle恢复需要的redo损坏,导致无法进行正常恢复,这种情况下,只能尝试强制打开库

SQL> recover database until cancel; ORA-00279: change 237857808 generated at 12/03/2024 07:06:31 needed for thread 1 ORA-00289: suggestion : C:\ORACLE\PRODUCT\10.2.0.3\DB_1\RDBMS\ARC20892_0929553713.001 ORA-00280: change 237857808 for thread 1 is in sequence #20892 Specify log: {<RET>=suggested | filename | AUTO | CANCEL} cancel ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below ORA-01194: file 1 needs more recovery to be consistent ORA-01110: data file 1: 'E:\ORADATA\xifenfei\SYSTEM01.DBF' ORA-01112: media recovery not started SQL> alter database open resetlogs; alter database open resetlogs * ERROR at line 1: ORA-01092: ORACLE instance terminated. Disconnection forced

对于这种ORA-01092错误,需要查看alert日志确认具体报错原因

由于对oracle粗心对于oracle版本判断失误,导致打开数据库失败,使用正确版本打开数据库发现ctl有报错,导致打开依旧失败(这种错误一般比较少见，大部分ctl异常都是在oracle mount状态无法成功)
