This article describes the installation of Oracle Client 11g Release 1 (11.10.6.0) on Oracle Enterprise Linux 5.0. Here I simulate the installation process based on my Desktop PC which has following hardware configuration:

1. Intel 2.4 GHz x86 Processor. 2. 80 GB SATA HDD 3. 1 GB physical memory

To make an easy and convenient installation process we documented installation Process in two phases. First of on we have to install Oracle Enterprise Linux Server 5.0 with required package and system parameter. After that in the second phase we simulated installation Process of Oracle 11g Client with respective screen shot which will help the beginner Administrator to understand their jobs easily. It’s me a great pleasure if this installation cook helps someone meet their company requirement.

Part-2: Configuring Linux for Oracle You may download Oracle 11g from oracle technology network. To download Oracle Database 11g Release 1 (11.1.0.6.0) Standard Edition, Standard Edition One, and Enterprise Edition use the following link. http://www.oracle.com/technology/software/products/database/oracle11g/111060_linuxsoft.html

1. Creating the Oracle Group and User Account

• Use the following command to add The Oracle Inventory group (oinstall) and OSDBS (dba) Group:

[root@tamim ~]# groupadd oinstall [root@tamim ~]# groupadd dba

• Use the following command to add a user whish is The Oracle software owner (oracle)

[root@tamim ~]# useradd oracle

• Use the following command to specify oinstall as the primary group and dba as the secondary group for oracle User.

[root@tamim ~]# usermod -g oinstall -G dba oracle

• Finaly use the following command to Check the Oracle user and user group:

[root@tamim ~]# id oracle uid=500(oracle) gid=500(oinstall) groups=500(oinstall),501(dba)

• Use the following command to set the password of the oracle user: [root@tamim ~]# passwd oracle

Changing password for user oracle. New UNIX password: Retype new UNIX password: passwd:all authentication tokens updated successfully.

• Use the Following Command determine whether the An unprivileged user (nobody) user exists or Not :

[root@tamim ~]# id nobody uid=99(nobody) gid=99(nobody) groups=99(nobody)

If this command displays information about the nobody user, then you do not need to create the nobody user.

• If the nobody user does not exist, then enter the following command to create it: # useradd nobody

2. Creating Required Directories and Change the Owner Ship

• Create directories with names similar to the following, and specify the correct owner, group, and permissions for them:

1. The Oracle base directory (For Oracle Home directory) 2. An optional Oracle data file directory

• Oracle Recommand that the base directory and data file directory will be different mount point. if you do not create the mount point during the operation system installation then use the following command to create a directory.

mkdir -p /mount_point/app/ For example : [root@tamim ~]# mkdir -p /u01/app

• To set the appropriate owner, group use the following command :

[root@tamim ~]# chown -R oracle.oinstall /u01

• To permissions on the directory use the following command : [root@tamim ~]# chmod -R 775 /u01

3. Verify Hardware Requirements

• Main Memory Requirements • Disk Space Requirements

Main Memory Requirements

• At least 1 GB of Physical RAM Requirement , To determine the physical RAM size, use the following command:

[root@tamim ~]# cat /proc/meminfo | grep Mem MemTotal: 1018368 kB MemFree: 43884 kB

• Swap Spase For 512 MB RAM,Swap Space Required Double the size of RAM For 1024 MB RAM, Swap Space Required 1.5 times the size of RAM

• To determine the physical RAM size, use the following command: [root@tamim ~]# cat /proc/meminfo | grep SwapTotal

SwapTotal: 2096472 kB Disk Space Requirements

• Oracle Recommend For Enterprise Edition you may need 3.47 GB, Enterprise Edition require 1.5 GB of disk Space for Data file. To determine the amount of free disk space in MB on the system, use the following command :


6

[root@tamim ~]# df -m /u01/ Filesystem 1M-blocks Used Available Use% Mounted on /dev/hda7 17439 3624 12915 22% /u01

[root@tamim ~]# df -m /u02/ Filesystem 1M-blocks Used Available Use% Mounted on /dev/hda6 17439 1777 14763 11% /u02

[NB: /u01 is use for Oracle Software and /u01 is use for Oracle Database file]

4. Software Requirements Checking

Kernel Requirements • To determine whether the required kernel is installed, use the following

command. A sample output displayed by running this command on a Oracle Enterprise Linux 5.0 system:

• To Find the Packege in the CD-ROM(Oracle Entriprece Linux) use the Commands similer

# ls -la /media/cdrecorder/Server | grep <package_name>

• To install, use commands similar to the following:

# rpm -ivh <package_name>

5. Configuring Kernel Parameters

[root@tamim ~]# sysctl -a | grep sem kernel.sem = 250 32000 100 128

[root@tamim ~]# sysctl -a | grep shm vm.hugetlb_shm_group = 0 kernel.shmmni = 4096 kernel.shmall = 268435456 kernel.shmmax = 4294967295 [root@tamim ~]# sysctl -a | grep file-max fs.file-max = 6553600

[root@tamim ~]# sysctl -a | grep ip_local_port_range net.ipv4.ip_local_port_range = 1024 65000

[root@tamim ~]# sysctl -a | grep rmem_ net.core.rmem_default = 4194304 net.core.rmem_max = 4194304

[root@tamim ~]# sysctl -a | grep wmem_ net.core.wmem_default = 262144 net.core.wmem_max = 262144 vm.lowmem_reserve_ratio = 256 256 32 • Using any text editor, create or edit the /etc/sysctl.conf file, and add or

edit lines similar to the following:

kernel.shmall = 2097152 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 = 4194304 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 262144
