又一例:ORA-600 kclchkblk_4和2662故障

发表于 2024 年 2 月 21 日由惜分飞

有客户恢复请求:由于未知原因导致aix环境的rac两台主机同时重启之后数据库无法正常启动,初步判断是由于写丢失导致故障（ORA-00742 ORA-00353）

后续检查发现obj$中的index异常（ORA-08102: index key not found, obj# 39）
类似文章:通过bbed修改obj$中dataobj$重现I_OBJ4索引报ORA-08102错误

对于此类问题使用非常规方法把obj$字典表进行重建（需要注意undo需要为自动管理方式,temp不能为空）,参考:
bootstrap$核心index(I_OBJ1,I_USER1,I_FILE#_BLOCK#,I_IND1,I_TS#,I_CDEF1等)异常恢复—ORA-00701错误解决

ora-600 2662和ora-600 kclchkblk_4恢复

发表于 2021 年 4 月 29 日由惜分飞

这两天连续处理两个case,一个是12.1.0.2版本数据库屏蔽一致性,强制open之后,报ORA-600 2662故障

这个错误本身是一个非常常见的错误,直接推scn即可解决,但是问题是12.1.0.2版本,oracle不允许以前常规的操作方法,就连oradebug都报错oradebug poke ORA-32521/ORA-32519故障解决,而且可以是rac环境,bbed修改文件头也相当麻烦,最后我们使用patch方法轻松解决

另外一例是11.2.0.4版本,强制open库报ora-600 kclchkblk_4
