getconf LONG_BIT显示的系统位数与uname -m 显示的系统位数不一致。

之前安装在红帽子系统上安装oracle过程中，遇到getconf LONG_BIT显示的系统位数为32位，而实际系统安装镜像时64位。导致启动oracle安装图形界面报错。

[root@sesprd oracle]# getconf LONG_BIT
32
[root@sesprd oracle]# uname -m
x86_64

解决办法，修改软件接

[root@sesprd oracleinstall]# cd /usr/libexec/getconf/
[root@sesprd getconf]# ls
