[Email protected] home]# passwd Oracle

2. Create database software directory and data file storage directory
Mkdir/home/oracle/app
Mkdir/home/oracle/app/oracle
Mkdir/home/oracle/app/oradata
Mkdir/home/oracle/app/oracle/product
Change directory owner is owned by Oracle user

Fi
Fi

4, modify the Linux kernel, modify the/etc/sysctl.conf file

Input command: vi/etc/sysctl.conf, press I to enter edit mode, add the following content to the article
Thing
Fs.file-max = 6815744
FS.AIO-MAX-NR = 1048576
Kernel.shmall = 2097152
Kernel.shmmax = 2147483648
Kernel.shmmni = 4096
Kernel.sem = 250 32000 100 128
Net.ipv4.ip_local_port_range = 9000 65500
Net.core.rmem_default = 4194304
Net.core.rmem_max = 4194304
Net.core.wmem_default = 262144
Net.core.wmem_max = 1048576

To make the/etc/sysctl.conf change take effect immediately, execute the following command

[Email protected] Home]#/sbin/sysctl-p

5. Configuring environment Variables for Oracle users
