redo异常 ORA-600 kclchkblk_4 故障恢复
朋友和我说,他们数据库由于存储控制器异常,导致数据库无法正常启动.
数据库recover database 提示需要已经覆盖的redo

数据库没归档,redo覆盖,无法继续恢复,使用_allow_resetlogs_corruption屏蔽前滚,继续恢复

参考:In 10.1.0.2: ORA-600 [kclchkblk_4] and ORA-600 [2662] After Recovery of Database (Doc ID 275902.1),删除tempfile继续打开数据库

数据库依然报ORA-00600kclchkblk_4]错误,因此解决该问题选择使用bbed修改文件头scn来完成,具体参考类似文章:使用bbed修复损坏datafile header

至此数据库恢复完成,建议逻辑方式重建数据库
