10 Gb installation of Oracle in Linux

1. Download the Installation File

Use the installation package 10201_database_linux32.zip and log on as the root user.

2. Check whether the system resources and environment meet the installation conditions.

Grep MemTotal/proc/meminfo: the memory size must be greater than 512 MB.

Grep SwapTotal/proc/meminfo

In addition, GB of disk space is required for 10 Gb.

[Root @ localhost ~] # Grep MemTotal/proc/meminfo

Add the content in Red Hat Enterprise Linux Server release 5 (Tikanga)

Change

Redhat-4

Install the required software package, for example: (you can download it from the Server where the system disk is installed)

3. Create users and groups, and orcale installation directory and data storage directory

[Root @ localhost ~] # Groupadd oinstall
[Root @ localhost ~] # Groupadd dba
[Root @ localhost ~] #/Usr/sbin/useradd-g oinstall-G dba Oracle
[Root @ localhost ~] # Passwd oracle
Changing password for user oracle.
New UNIX password:
Bad password: it is WAY too short
Retype new UNIX password:
Sorry, passwords do not match.
New UNIX password:
Retype new UNIX password:
Passwd: all authentication tokens updated successfully.
[Root @ localhost ~] # Mkdir/opt/oracle
[Root @ localhost ~] # Mkdir/opt/oradata
[Root @ localhost ~] # Chown-R oracle: oinstall/opt/oracle/opt/oradata
[Root @ localhost ~] # Chmod-R 755/opt/oracle/opt/oradata

4. Configure Environment Variables

 

Switch users and configure user environment variables

[Root @ localhost ~] # Su oracle
[Oracle @ localhost root] $ vi/home/oracle/. bash_profile

Add the following content:

#. Bash_profile

# Get the aliases and functions
If [-f ~ /. Bashrc]; then
.~ /. Bashrc
Fi

# User specific environment and startup programs
# Controls the maximum shared segment size, in bytes
Kernel. shmmax = 2147483648
Kernel. shmmni = 4096
Kernel. sem = 250 32000 100 128
Fs. file-max = 65536
Net. ipv4.ip _ local_port_range = 1024 65000
Net. core. rmem_default = 262144
Net. core. rmem_max = 262144
Net. core. wmem_default = 262144
Net. core. wmem_max = 262144

# Controls the maximum number of shared memory segments, in pages
Kernel. shmall = 2097152

ORACLE_BASE =/opt/oracleORACLE_SID = orclORACLE_HOME = $ ORACLE_BASE/product/10.2.0/region = $ ORACLE_HOME/libPATH = $ PATH: $ HOME/bin: $ ORACLE_HOME/binexport ORACLE_BASE ORACLE_SID ORACLE_HOME export PATH

5. Set System Parameters
Switch to root user

# Controls the maximum shared segment size, in bytes
Kernel. shmmax = 2147483648
Kernel. shmmni = 4096
Kernel. sem = 250 32000 100 128
Fs. file-max = 65536
Net. ipv4.ip _ local_port_range = 1024 65000
Net. core. rmem_default = 262144
Net. core. rmem_max = 262144
Net. core. wmem_default = 262144
Net. core. wmem_max = 262144

# Controls the maximum number of shared memory segments, in pages
Kernel. shmall = 2097152
