问题描述:安装oracle过程中出现上述报错

解决办法:先执行该命令sudo apt-get update  然后再执行安装对应的依赖库即可

 

报错信息::sysctl: cannot stat /proc/sys/–p: No such file or directory

问题描述:这是我再安装Oracle时，修改/etc/sysctl.conf文件添加对应的参数后，保存执行sysctl -p更新内核参数命令报的错

解决办法:

通过执行执行如下两条命令即可:
modprobe bridge
lsmod|grep bridge
最后再重新执行
sysctl -p
会显示对应的内核参数:
fs.aio-max-nr = 65536
fs.file-max = 13158378
kernel.shmall = 18446744073692774399
kernel.shmmax = 18446744073692774399
kernel.shmmni = 4096
kernel.sem = 32000 1024000000 500 32000
net.ipv4.ip_local_port_range = 32768 60999
net.core.rmem_default = 212992
net.core.rmem_max = 212992
net.core.wmem_default = 2129
表示这一步成功
