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）

难见的oracle 9i恢复—2023年

发表于 2023 年 5 月 15 日 由 惜分飞

时过境迁,以前恢复大量oracle 8/9版本的库,现在一套oracle 9i的库都比较稀奇了.今天恢复客户一套9.2.0.6的aix环境rac库,通过分析确认主要问题:
1. 重建控制文件，resetlogs库遗漏数据文件
missing_dbf

2. 数据库启动主要报错ORA-600 2663和ORA-600 kclchkblk_4

根据客户文件名称的规则,推算出来84号文件实际的文件名(因为使用的是lv[aix的hacmp管理的lv的裸设备方式]),通过dbv确认文件无坏块

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
20210429220218

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

这个比较简单,参考redo异常 ORA-600 kclchkblk_4 故障恢复.
