ORACLE11G based Linux 6.3 installation

First, the installation package:

P13390677_112040_linux-x86-64_1of7.zip

P13390677_112040_linux-x86-64_2of7.zip

Second,: Configure global parameters:

1. Configure permissions for Oracle users: vim/etc/security/limits.conf

In the last line of configuration, write the following:

Oracle Soft Nofile 65536

Oracle Hard Nofile 65536

Oracle Soft Nproc 16384

Third, create Oralce database users and user groups

Create Data user group: DBA

Groupadd dba

Create an Installation user group: Oinstall

Groupadd Oinstall

Create User: Oracle

Useradd-g oinstall-g dba-m Oracle//-m do not automatically create a user's log in directory

Set User password:

passwd Oracle

Iv. Creating file directories and permissions for Oracle use:

1. Create the Oracle Base directory:

Mkdir-p/u01/app/oracle

mkdir Creating a Directory command

-P can create multiple subdirectories at the same time

2. Assign users and groups to the base directory:

Chown-r oracle.oinstall/u01/

Chown changing the owning user and owning group

-R changes the user and the owning group of all subdirectories under the day directory
