RedHat 7.4 安装Oracle 19c

之前装过18c和19c，虽然装成功了，但不符合规范吧，所以把之前的两篇安装的文章给删了怕误导别人。

因为：

从Oracle 18c开始，在安装数据库软件时，需要把压缩文件解压到$ORACLE_HOME路径下，在此目录下运行./runInstaller

19c安装来来回回拖了很久，没什么自己的时间。这篇就当个笔记吧。

修改（或新建）/etc/sysctl.d/97-oracle-database-sysctl.conf

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 4294967295

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

The /etc/sysctl.conf file has been deprecated.
