Installing Oracle 11g R2 in Linux
I. installation environment

Linux Server: CentOS 6.4 64-bit

Oracle Server: Oracle 11gR2 64-bit

Ii. System Requirements

1. Requirements for installing Oracle in Linux

System Requirements	Description
Memory	Physical memory must be higher than 1 GB
Swap space	Generally, it is twice the memory size. For example, you can set the swap partition size to 3 GB for 1 GB memory.

2. Modify core operating system parameters

Perform the following steps under the Root user:

1) modify the user's SHELL restrictions and modify the/etc/security/limits. conf file

Enter the command vi/etc/security/limits. conf, press the I key to enter the editing mode, and add the following content to the file.

1234	oracle  soft    nproc    2047oracle  hard    nproc    16384oracle  soft    nofile    1024oracle  hard    nofile    65536

After editing, Press Esc and enter ": wq" to save the disk and exit.

2) modify the/etc/pam. d/login file and enter the command: vi/etc/pam. d/login,

Press the I key to enter the editing mode and add the following content to the file.

12	session  required    /lib/security/pam_limits.so session  required    pam_limits.so

After editing, Press Esc and enter ": wq" to save the disk and exit.

3) modify the Linux kernel, modify the/etc/sysctl. conf file, and enter the command vi/etc/sysctl. conf,

Press the I key to enter the editing mode and add the following content to the file.

1234567891011

fs.file-max = 6815744fs.aio-max-nr = 1048576kernel.shmall = 2097152kernel.shmmax = 2147483648kernel.shmmni = 4096kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default = 4194304net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048576

After editing, Press Esc and enter ": wq" to save the disk and exit.

4) to make the/etc/sysctl. conf change take effect immediately, run the following command. Input: sysctl-p:

1234567891011121314

linux:~ # sysctl -pnet.ipv4.icmp_echo_ignore_broadcasts = 1net.ipv4.conf.all.rp_filter = 1fs.file-max = 6815744fs.aio-max-nr = 1048576kernel.shmall = 2097152kernel.shmmax = 2147483648kernel.shmmni = 4096kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default = 4194304net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048576

5) edit/etc/profile and enter the command: vi/etc/profile,

Press the I key to enter the editing mode and add the following content to the file.

12345678

if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then   ulimit -p 16384  ulimit -n 65536else  ulimit -u 16384 -n 65536fifi

After editing, Press Esc and enter ": wq" to save the disk and exit.

6) Create related users and groups as owners of software installation and support groups.

1234567891011

Create a user and enter the following command: groupadd  oinstall groupadd  dba Create an Oracle user and password, and enter the following command: useradd -g oinstall -g dba -m oraclepasswd  oracle Then you will be asked to enter the password and the password will be input at will.2Times, but must be consistent, press enter to confirm

7) Create a database software directory, a data file storage directory, and a directory location based on your needs. Pay attention to the disk space,

Here I put it under the oracle user, for example:

123456

Enter the following command: mkdir /home/oracle/appmkdir /home/oracle/app/oraclemkdir /home/oracle/app/oradatamkdir /home/oracle/app/oracle/product

8) change the directory owner to be owned by an Oracle user and enter the following command:

1	chown -R oracle:oinstall /home/oracle/app

9) configure the environment variables of oracle users. First, switch to the newly created oracle user,

Input: su-oracle, and then directly enter: vi. bash_profile

Press I to edit. bash_profile, enter the editing mode, and add the following content:

1234567

umask 022export ORACLE_BASE=/home/oracle/appexport ORACLE_HOME=$ORACLE_BASE/oracle/product/11.2.0/dbhome_1export ORACLE_SID=orclexport PATH=$PATH:$HOME/bin:$ORACLE_HOME/binexport LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib  (32Bit System)export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib64  (64Bit System)2Select1Yo

After editing, Press Esc and enter ": wq" to save the disk and exit. source. bash_profile will take effect immediately!

3. Install and install the software on which Oracle depends

1. Install YUM

1	yum -y install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh numactl-devel glibc-headers

Unzip: unzip pdksh-5.2.14.zip

32-bit or 64-bit installation depends on the system.

1	rmp –ivh pdksh-5.2.14-30.x86_64.rpm

Iv. Installation Process

1) After all the required operations are completed, log out of the system and log in as an Oracle user on the graphic interface. First, copy the downloaded Oracle Installation Package to linux,

We recommend that you use Xmanager or other ftp tools to copy the created/home/oracle/directory.

Open a terminal and run the unzip command to decompress the oracle Installation File, for example:

123	Enter the following command:unzip  linux.x64_11gR2_database_1of2.zip unzip  linux.x64_11gR2_database_2of2.zip

After decompression, cd enters the decompressed directory/home/oracle/database. The files are extracted and merged.

12	Enter the following command:cd  database

Run the ls command to view the files contained in the decompressed database, for example:

 

 2) execute the installation and execute the following statements to bring up the interface.

1234	su - rootxhost +su - oracle./runInstaller

 

Select install database soft only

Select single instance database installation

Select language

Select Enterprise edition

If you do not install the software that Oracle depends on and install it, it will appear. If it does not appear after installation.

Next finish

After the installation is complete, the system prompts you to use the root permission to execute two shell scripts. (Do not close the pop-up window) follow the prompt path to find its location,

For example, in/home/oracle/app/oracle/product/11.2.0/dbhome_1/root. sh

And/home/oracle/app/oraInventory/orainstRoot. sh to open a new terminal, enter the command:

 

123	su – rootcd  /home/oracle/app/oracle/product/11.2.0/dbhome_1sh  root.sh

 

12	cd /home/oracle/app/oraInventorysh  orainstRoot.sh
