redhat 7安装Oracle缺少compat-libstdc++

Posted on 2019 年 02 月 28 日 by 惜分飞

在redhat 7版本中compat-libstdc++-33-3.2.3包被从ISO文件中移除,但是12c及其以后版本安装均需要该包,导致数据库在安装的时候检查无法通过
redhat 7光盘中无compat-libstdc包

通过mos相关描述,该包主要是影响数据库的Oracle Text中的相关功能,如果不使用该功能,可以通过忽略该包继续安装,如果需要使用该功能,可以通过下载compat-libstdc来安装.

这个明显io错误比较多,无法直接使用以前的dd方法较好的恢复数据,只能通过linux平台的一些io工具修复文件(或者直接把磁盘挂载到win上通过工具处理),然后下载到win机器之后效果不错,只有17个坏块
