Install Oracle11g (64bit) in Linux6)

The oracle11gr2package contains two files: linux_11gr2_database_1of2.zipand linux_11gr2_database5of2.zip. These two files are uploaded to usrloca through SSH.

The oracle11gr2package contains two files: linux_11gr2_database_1of2.zipand linux_11gr2_database5of2.zip. These two files are uploaded to/usr/loca over SSH.

1. Prepare the Oracle Installation File

The oracle11gr2package contains two files: linux_11gr2_database_1of2.zipand linux_11gr2_database5of2.zip. These two files are uploaded to/usr/local/oracle over SSH.

Decompress the installation file to the current directory.

[Root @ localhostroot] # cd/usr/local/oracle

[Root @ localhostoracle] # unzip linux_11gR2_database_1of2.zip

[Root @ localhostoracle] # unzip linux_11gr2_database204 f2.zip

After the preceding command is executed, the directory named database is generated under/usr/local/oracle/, which is the directory of the oracle installer.

2. Prepare the target installation directory for oracle

[Root @ localhost oracle] # mkdir-p/u01/app/oracle

[Root @ localhost oracle] # chown-R oracle: oinstall/u01/app/oracle

[Root @ localhost oracle] # chmod-R 755/u01/app/oracle

The installation target directory is the directory where you want to install oracle. This time, we will install oracle in the/u01/app/oracle directory. The following is the Directory Creation command.

3. Create oracle users and user groups

Oracle cannot be installed under the root account. Therefore, you must create a user for oracle Installation and create user groups for dba and oinstall.

[Root @ localhostoracle] # groupadd dba

[Root @ localhost oracle] # groupadd oinstall

The following command creates the dba and oinstall user groups:

The following command creates an oracle user and sets the password

[Root @ localhostoracle] # useradd-g oinstall-G dba oracle

[Root @ localhostoracle] # passwd oracle

Changing password for user oracle.

New UNIX password: [enter a password here]

Bad password: it is based on a dictionary word

Retype new UNIX password: [enter the password again here]

Passwd: all authentication tokens updated successfully.

The following command assigns the oracle Installation Directory (/opt/oracle) to the oracle user oinstall User Group

[Root @ localhost oracle] # chown-R oracle: oinstall/u01/app/oracle

4. Check and install the RPM software package on which ORACLE depends

Some linux software packages on which oracle Installation depends are not installed. This requires that these uninstalled software packages be installed before oracle can be installed properly. These uninstalled software packages can be obtained on the linux installation CD. We can install these software packages directly on the linux Cd (or directly copy the required software packages to the linux local disk ), first, run the following command to mount the linux CD:

[Root @ localhost oracle] # mkdir/mnt/cdrom

[Root @ localhost oracle] # mount/dev/cdrom/mnt/cdrom

Install the missing software package. Here, only the software package missing for this linux system is installed. For example, when you check the software package during oracle Installation and find that the required software package is not installed, you can install the missing software package again based on the name of the software package that is not installed. The installation command is as follows:

[Root @ localhostoracle] #

5. Set Linux Kernel Parameters

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

# 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 = 262144

Fs. file-max = 6815744

Net. ipv4.ip _ local_port_range = 9000 65500

Net. core. wmem_max = 1048576

Fs. aio-max-nr = 1048576

Run the following command to change the current kernel parameters:

#/Sbin/sysctl-p

6. Modify/etc/security/limits. conf

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

Oracle soft nproc 2047

Hard nproc 16384

Oracle soft nofile 1024

Oracle hard nofile 65536

7. modify the system environment variable/etc/profile

Modify the environment variable/etc/profile and add the following content:

If [$ USER = "oracle"]; then

If [$ SHELL = "/bin/ksh"]; then

Ulimit-p 16384

Ulimit-n 65536

Else
Ulimit-u 16384-n 65536
Fi
Fi

8. Set ORACLE environment variables

Set the default mask value:

[Root @ localhost oracle] # umask 022

Set the remote logon variable DISPLAY:

Export DISPLAY = local_host: 0.0

Modify the environment variable configuration file of the oracle user home directory (/home/oracle ~ /. Bash_profile. Use the following command

[Root @ localhost oracle] # vi/home/oracle/. bash_profile

Add the following content to the configuration file:

Export ORACLE_SID = orcl (note that this value must be the same as the name of the database instance created below)

Export ORACLE_BASE =/opt/oracle/app

Export ORACLE_HOME = $ ORACLE_BASE/product/11.2.0/dbhome_1

Export PATH = $ PATH: $ HOME/bin: $ ORACLE_HOME/bin

Export LD_LIBRARY_PATH = $ ORACLE_HOME/lib:/usr/lib

9. Start the installation process

After completing the preceding steps, we recommend that you restart the system to make all settings take effect. Now you can log on with an 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 ).

1
2

[Root @ localhost oracle] # su-oracle

[Oracle @ localhost oracle] # cd/usr/local/oracle/database

Run the installation command

1

[Oracle @ localhost database] #./runInstaller

There are two options: desktop and server. Select server ).

You can choose to install only the database software, that is, do not create common database instances and database files

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

$ ORACLE_HOME/bin/netca

Install an instance or database

$ ORACLE_HOME/bin/dbca

When you complete the preceding operations, we recommend that you restart the system once to prevent some settings from taking effect. After the restart, log on to the oracle database, open the terminal, and enter the following command to run the following command:

Start the listener:

[Root @ localhostoracle] $ lsnrctl start

Start the database and instance:

[Root @ localhost oracle] $ sqlplus/nolog

[Root @ localhost oracle] $ conn/as sysdba

After entering sqlplus, run the database startup command. The following command creates, installs, and opens an ORACLE instance. In this case, the database system is in normal operation and can accept user requests.

SQL> startup

Disable

SQL> shutdown immediate
