ora-600 2662和ora-600 kclchkblk_4恢复

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
