Install Oracle 11g R2 on Ubuntu 10.10

1. Preparations
1.1 If the server version is used, a graphical interface must be installed.
$ Sudo apt-get install Ubuntu-desktop

1.2 install necessary library packages
$ Sudo apt-get install build-essential libaio1 gawk ksh libmotif3 alien libtool lsb-rpm

$ Sudo apt-get install libstdc ++ 5 this step is very important. If you do not install it, The MakefileException error in invoking target 'install' of makefile ins_ctx.mk error may occur. The reason is that ubuntu10 + uses libstdc ++ 6 as the default version by default.

1.3 create a soft connection for some commands
$ Su-
# Ln-sf bash/bin/sh
# Ln-s/usr/bin/awk
# Ln-s/usr/bin/rpm
# Ln-s/usr/bin/basename
# Mkdir/etc/rc. d
# For I in 0 1 2 3 4 5 6 S; do ln-s/etc/rc $ I. d/etc/rc. d/rc $ I. d; done

2. Create Oracle users, user groups, and folders

2.1 create an oinstall and dba User Group
$ Su-
# Addgroup oinstall
# Addgroup dba
 
2.2 create an oracle user and specify the user group created above
 
-- Create an oracle user
# Useradd-g oinstall-G dba-d/home/oracle-s/bin/bash oracle
-- Set Password
# Passwd oracle

2.3 create a folder
-- Create the oracle user home directory
$ Su-
# Mkdir/home/oracle
# Chown-R oracle: dba/home/oracle
 
-- Create the ORACLE_BASE directory
# Mkdir-p/u01/oracle note in this step/u01 occupies "/" file system space by default. This location can be changed, for example, to/opt/oracle

# Chown-R oracle: dba/u01

3. Set System Parameters

3.1 Edit the/etc/sysctl. conf file and add the following parameters to the end. Note: This file should be backed up before modification.
$ Su-
# Cp/etc/sysctl. conf/etc/sysctl. conf. bak
----------------------
Add the following parameters to the end of the sysctl. conf file.
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. core. rmem_default = 4194304
Net. core. rmem_max = 4194304
Net. core. wmem_default = 1048576
Net. core. wmem_max = 1048576
Net. ipv4.ip _ local_port_range = 9000 65535

3.2 edit/etc/security/limits. conf and add the following parameters to the end of the file.
Note: backup should be performed before editing.
-----------
Oracle soft nproc 2047
Hard nproc 16383
Oracle soft nofile 1023
Oracle hard nofile 65535

3.3 modify the/etc/pam. d/login file and add the following two line parameters:
Session required/lib/security/pam_limits.so
Session required pam_limits.so

3.4 activate configuration in sysctl. conf
$ Su-
# Sysctl-p

3.5 Modify/etc/profile and set Environment Variables
ORACLE_SID = orcl
ORACLE_BASE =/u01/oracle
ORACLE_HOME =/u01/oracle/product/11.0.2
NLS_LANG = AMERICAN_AMERICA.UTF8
PATH = $ ORACLE_HOME/bin: $ PATH
Export ORACLE_BASE ORACLE_SID ORACLE_HOME PATH NLS_LANG

4. Prepare the Installation File

4.1 download the installation file from the official website and copy the file to/u01

$ Unzip linux_11gR2_database_1of2.zip
$ Unzip linux_11gr2_databasesilicate f2.zip

The total size is about 2.2 GB, and the above files are 32-bit.

4.2 After decompression, the database folder will appear, which is the installation file. Specify permissions for the Installation File.

$ Sudo chmod 755 u01/oracle/database
$ Sudo chmod 755 u01/oracle/database /*.*
$ Sudo chmod 755 u01/oracle/database/install/. oui
$ Sudo chmod 755 u01/oracle/database/install /*.*
$ Sudo chmod 755 u01/oracle/database/install/unzip

$ Chown-R oracle: dba/u01/database/

5. Start Installation

5.1 The installation requires a graphical interface. If the cocould not initialize class sun. awt. X11.XToolkit exception occurs, run the following command to configure it.
 
$ Su-
# Xhost + 127.0.0.1
Or
# Export DISPLAY =: 0.0

5.2 Installation started
$ Su-oracle
$ Export LANG = en_US
$ Cd/u01/database
$./RunInstaller-jreLoc/opt/lib/jdk1.6.0 _ 25-ignoreSysPrereqs
Specify the JRE directory and ignore the version check.

----------- End -----------------

Note:

1. When "Database Configuration Assist" is installed, the interface is blank, which is normal. This step takes a long time. After this step is completed, an Instance name, service name, and other information Prompt window will pop up.

2. After the installation is successful, execute sqlplus system/pwd under the oracle user to log on successfully, but an error will be reported after switching to the daily user. Because ORACLE_SID is not specified in the environment variable of daily users. Modify ~ /. Bashrc or ~ /. Bash_profile file, add export ORACLE_SID = orcl.

If the sqlplus command cannot be found under a daily user, a soft connection is created to/bin.
$ Sudo ln-s $ ORACLE_HOME/bin/sqlplus
