Linux 6 under Install oracle11g (64bit)

First, prepare the Oracle installation files

The ORACLE11GR2 contains two files Linux_11gr2_database_1of2.zip and Linux_11gr2_database_2of2.zip, which uploads the two files to/usr/local/oracle via SSH.

Unzip the installation file to the current directory

[[email protected]] #cd/usr/local/oracle[[email protected]] #unzip linux_11gr2_database_1of2.zip[[email protected]]# Unzip Linux_11gr2_database_2of2.zip

After executing the above command, a directory named database will be generated under/usr/local/oracle/, which is the directory of the Oracle installer.

Ii. preparing the installation target directory for Oracle

[[Email protected] Oracle] #mkdir-P/u01/app/oracle[[email protected] Oracle] #chown-R oracle:oinstall/u01/app/oracle[ [Email protected] Oracle] #chmod-R 755/u01/app/oracle

The installation target directory is the directory where the user wants to install Oracle, and this time we will install Oracle to/ U01/app /oracle Directory, the following is the directory Creation command.

Iii. creating Oracle-related users and user groups

Oracle cannot install under the root account, so you need to create a dedicated user for the installation of Oracle, and you need to create DBA and Oinstall user groups.

[[email protected]] #groupadd dba[[email protected] Oracle #groupadd Oinstall

The following command creates the DBA and the Oinstall user group:

The following command creates the Oracle user and sets the password

[[email protected]] #useradd-G oinstall-g dba Oracle[[email protected]] #passwd Oracle

changing password Foruser Oracle.

New UNIX password:[Type the password here]

Bad Password:it isbased on a dictionary word

Retype new Unixpassword: [Retype password here]

Passwd:allauthentication Tokens updated successfully.

The following command assigns the Oracle installation directory (/opt/oracle) to the Oracle User Oinstall user Group

[[Email protected] Oracle] #chown –R oracle:oinstall/u01/app/oracle

Iv. checking the installation of Oracle-dependent RPM packages

Oracle's installation depends on the package, and some Linux is not installed. This requires that these not yet installed packages are installed before Oracle can be installed properly. These non-installed packages are available on the Linux installation CD, we install the packages directly on the Linux CD (or copy the required packages directly to the Linux local disk), first we need to mount the Linux CD and use the following command:

[[Email protected] Oracle] #mkdir/mnt/cdrom[[email protected] Oracle #mount/dev/cdrom/mnt/cdrom

Install the missing packages and install only the packages that are missing from this Linux system. In the case of an Oracle installation, when the package is checked, it is found that the required package is not installed, you can install the missing package again according to the name of the package that is not installed. The following are the installation commands:

[[email protected]] #rpm  -ivh binutils-2.20.51.0.2-5.11.el6 (x86_64) rpm -ivh  compat-libcap1-1.10-1  (x86_64) rpm -ivh compat-libstdc++-33-3.2.3-69.el6 (x86_64) RPM -IVH  compat-libstdc++-33-3.2.3-69.el6.i686rpm -ivh gcc-4.4.4-13.el6  (x86_64) RPM -IVH  gcc-c++-4.4.4-13.el6  (x86_64) rpm -ivh glibc-2.12-1.7.el6  (i686) rpm -ivh  glibc-2.12-1.7.el6  (x86_64) rpm -ivh glibc-devel-2.12-1.7.el6 (x86_64) rpm -ivh  glibc-devel-2.12-1.7.el6.i686rpm -ivh kshrpm -ivh libgcc-4.4.4-13.el6  (i686) rpm  -ivh libgcc-4.4.4-13.el6  (x86_64) rpm -ivh libstdc++-4.4.4-13.el6  (x86_64) rpm - Ivh libstdc++-4.4.4-13.el6.i686rpm -ivh libstdc++-devel-4.4.4-13.el6 (x86_64) rpm -ivh  libstdc++-devel-4.4.4-13.el6.i686rpm -ivh libaio-0.3.107-10.el6  (x86_64) rpm -ivh  libaio-0.3.107-10.el6.i686rpm -ivh  Libaio-devel-0.3.107-10.el6 (x86_64) rpm -ivh libaio-devel-0.3.107-10.el6.i686rpm -ivh  make-3.81-19.el6rpm -ivh sysstat-9.0.4-11.el6  (x86_64)

Five, set the Linux kernel parameters

Open Modify/etc/sysctl.conf and add the following at the end

#kernel. Shmall =2097152

#kernel. Shmmax =2147483648

Kernel.shmmni = 4096

Kernel.sem = 25032000 100 128

net.core.rmem_default= 4194304

Net.core.rmem_max =4194304

net.core.wmem_default= 262144

Fs.file-max = 6815744

Net.ipv4.ip_local_port_range= 9000 65500

Net.core.wmem_max =1048576

Fs.aio-max-nr =1048576

Execute the following command to change the current kernel parameters:

#/sbin/sysctl-p

Vi. Modification of/etc/security/limits.conf

Modify/etc/security/limits.conf, add content

Oracle Soft nproc2047

Oracle Hard nproc16384

Oracle Soft nofile1024

Oracle Hard nofile65536

Seven, modify the system environment variable/etc/profile

To modify the environment variable/etc/profile, add the following:

if [$USER = "Oracle"]; Then

if [$SHELL = "/bin/ksh"]; Then

Ulimit-p 16384

Ulimit-n 65536

Else
Ulimit-u 16384-n65536
Fi
Fi

VIII. Setting Oracle Environment variables

Set the default Mask values:

[email protected] oracle]# umask 022

Set remote login variables DISPLAY :

exportdisplay=local_host:0.0

Modify the environment variable profile ~/.bash_profile for the Oracle User home directory (/home/oracle). Use the following command

[Email protected]oracle] #vi/home/oracle/.bash_profile

Add the following to the configuration file

EXPORTORACLE_SID=ORCL (Note that this value is the same as the database instance name created below)

Exportoracle_base=/opt/oracle/app

Exportoracle_home= $ORACLE _base/product/11.2.0/dbhome_1

Exportpath= $PATH: $HOME/bin: $ORACLE _home/bin

Exportld_library_path= $ORACLE _home/lib:/usr/lib

Nine, start the installation process

After the above steps are set up, it is recommended that you restart the system so that all settings take effect. Now log in with the Oracle user and go to the Oracle installer directory. Each of the following steps is a step in the Oracle installation process (each step corresponds to an Installation interface).

[[Email protected] Oracle] # Su-oracle[[email protected] Oracle #cd/usr/local/oracle/database

Run the Install command

[[Email protected] database] #./runinstaller

There are two options for the desktop class and server class, where server classes (servers)are selected.

You can choose to install only the database software, that is, do not create the usual DB instance and database files

If you install only the database software, you can configure the listener after the installation is complete .

$ORACLE _HOME/BIN/NETCA

Installing an instance or database

$ORACLE _HOME/BIN/DBCA

When you are done, it is recommended that you restart it again to prevent certain settings from taking effect. After restarting with Oracle User login, open terminal, type the following command to run the following command

Start monitoring:

[[email protected]] $lsnrctl start

To start the database and instance:

[[Email protected] Oracle] $sqlplus/nolog[[email protected] Oracle $conn/as SYSDBA

After entering Sqlplus, execute the start database command, and the following command will create, install, and open the Oracle instance. At this point, the database system is in a normal working state and can accept user requests.

Sql>startup

Closed with

Sql>shutdownimmediate
