Installing the Oracle 11GR2 database on Oracle Enterprise Linux R5U7

Toss it several times, experience is:

Installation of the package

In the installation package, the development of the installation package must be installed.

In addition, after the installation is complete, the packages that need to be installed include:

modifying system parameters

Modify the/etc/sysctl.conf file to add the following command
Kernel.sem = 250 32000 100 128
Net.ipv4.ip_local_port_range = 1024 65000
Net.core.rmem_default = 4194304
Net.core.rmem_max = 4194304
Net.core.wmem_default = 262144
Net.core.wmem_max = 262144
Fs.file-max = 6553600
Make the configuration file effective
/sbin/sysctl-p

Add the following command to/etc/security/limits.conf
Oracle Soft Nproc 2047

Create sub-file directories, set owners, groups, and permissions
Mkdir-p/u01/app
Chown-r Oracle:oinstall/u01/app
Chmod-r 775/u01/app

Logging on to Oracle users
Modify Umask settings to ~/.bash_profile
