1 Reviewing Information About This Guide

This guide describes how to complete a default installation of Oracle Database Client on a system that does not have any Oracle software installed on it. It describes how to install one of the following installation types:

- Administrator: Enables applications to connect to an Oracle Database instance on the local system or on a remote system. It also provides tools that enable you to administer Oracle Database.

- Runtime: Enables applications to connect to an Oracle Database instance on the local system or on a remote system.

- Instant Client: Enables you to install only the shared libraries required by Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI), Pro*C, or Java database connectivity (JDBC) OCI applications. This installation type requires much less disk space as compared to the other Oracle Database Client installation types.

2 Logging In to the System as root

Before you install the Oracle software, you must complete several tasks as the root user. To log in as the root user, complete one of the following procedures:

Note:
Unless you intend to complete a silent-mode installation, you must install the software from an X Window System workstation, an X terminal, or a PC or other system with X server software installed.

- Following are the steps for installing the software from an X Window System workstation or X terminal:

1. Start a local terminal session, for example, an X terminal (xterm).

2. If you are not installing the software on the local system, then enter the following command to enable the remote host to display X applications on the local X server:

$ xhost fully_qualified_remote_host_name

For example:

$ xhost somehost.us.example.com

3. If you are not installing the software on the local system, then use the ssh, rlogin, or telnet command to connect to the system where you want to install the software:

$ telnet fully_qualified_remote_host_name

4. If you are not logged in as the root user, then enter the following command to switch user to root:

$ sudo sh
password:
#

- Following are the steps for installing the software from a PC or other system with X server software:

Note:
If necessary, refer to your X server documentation, or contact your X server vendor or system administrator for more information about completing this procedure. Depending on the X server software that you are using, you may have to complete the tasks in a different order.

1. Start the X server software.

2. Configure the security settings of the X server software to permit remote hosts to display X applications on the local system.

3. Connect to the remote system where you want to install the software and start a terminal session on that system, for example, an X terminal (xterm).

4. If you are not logged in as the root user on the remote system, then enter the following command to switch user to root:

$ sudo sh
password:
#

3 Checking the Hardware Requirements

The system must meet the following minimum hardware requirements:

- Memory Requirements

- Disk Space Requirements

3.1 Memory Requirements

The following are the memory requirements for installing Oracle Database 11g Release 2 (11.2):

- At least 256 MB of physical RAM.
To determine the physical RAM size, enter the following command:

# grep MemTotal /proc/meminfo

If the size of the physical RAM is less than the required size, then you must install more memory before continuing.

- The following table describes the relationship between installed RAM and the configured swap space recommendation:

Note:
On Linux, the HugePages feature allocates non-swappable memory for large page tables using memory-mapped files. If you enable HugePages, then you should deduct the memory allocated to HugePages from the available RAM before calculating swap space.

Available RAM

Swap Space Required

Between 0 MB and 256 MB

3 times the size of RAM

Between 256 MB and 512 MB

2 times the size of RAM

Between 512 MB and 2 GB

1.5 times the size of RAM

Between 2 GB and 16 GB

Equal to the size of RAM

More than 16 GB

16 GB

- To determine whether the system architecture can run the software, enter the following command:

# grep "model name" /proc/cpuinfo

Note:
This command displays the processor type. Verify that the processor architecture matches the Oracle software release to install. If you do not see the expected output, then you cannot install the software on this system.

To determine the size of the configured swap space, enter the following command:

# grep SwapTotal /proc/meminfo

If necessary, refer to the operating system documentation for information about how to configure additional swap space.

To determine the available RAM and swap space, enter the following command:

# free

IMPORTANT:

- Oracle recommends that you take multiple values for the available RAM and swap space before finalizing a value. This is because the available RAM and swap space keep changing depending on the user interactions with the computer.

- Contact your operating system vendor for swap space allocation guidance for your server. The vendor guidelines supersede the swap space requirements listed in this guide.

3.2 Disk Space Requirements

The following are the disk space requirements for installing Oracle Database 11g Release 2 (11.2):

- The minimum disk space requirement for a client install in the /tmp directory is 400 MB.
To determine the amount of disk space available in the /tmp directory, enter the following command:

# df -k /tmp

If there is less than 400 MB of free disk space available in the /tmp directory, then complete one of the following steps:

- Delete unnecessary files from the /tmp directory to meet the disk space requirement.

- Set the TMP and TMPDIR environment variables when setting the oracle user's environment.

See Also:
"Configuring the oracle User's Environment for more information about setting TMP and TMPDIR

- Extend the file system that contains the /tmp directory. If necessary, contact the system administrator for information about extending file systems.

- Between 146 MB and 1.38 GB of disk space for the Oracle software, depending on the installation type:

Installation Type

Requirement for Software Files

Instant Client

146 MB

Administrator

1.38 GB

Runtime

1.10 GB

To determine the amount of free disk space on the system, enter the following command:

# df -k

5 Creating Required Operating System Groups and Users

The following local operating system groups and users are required if you are installing Oracle Database:

- The Oracle Inventory group (typically, oinstall)

- The Oracle software owner (typically, oracle)

To determine whether these groups and users exist, and if necessary, to create them, follow these steps:

1. To determine whether the oinstall group exists, enter the following command:

# more /etc/oraInst.loc

If the output of this command shows the oinstall group name, then the group exists.

If the oraInst.loc file exists, then the output from this command is similar to the following:

inventory_loc=/u01/app/oraInventory
inst_group=oinstall

The inst_group parameter shows the name of the Oracle Inventory group, oinstall.

2. If necessary, enter the following commands to create the oinstall group:

# /usr/sbin/groupadd oinstall

3. To determine whether the oracle user exists and belongs to the correct groups, enter the following command:

# id oracle

If the oracle user exists, then this command displays information about the groups to which the user belongs. The output should be similar to the following, indicating that oinstall is the primary group and dba is a secondary group:

uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)

4. If necessary, complete one of the following actions:

- If the oracle user exists, but its primary group is not oinstall or it is not a member of the dba group, then enter the following command:

# /usr/sbin/usermod -g oinstall -G dba oracle

- If the oracle user does not exist, enter the following command to create it:

# /usr/sbin/useradd -g oinstall -G dba oracle

This command creates the oracle user and specifies oinstall as the primary group and dba as the secondary group.

5. Enter the following command to set the password of the oracle user:

# passwd oracle

6 Creating Required Directories

Note:
If you do not want to create a separate Oracle data file directory, then you can install the data files in a subdirectory of the Oracle base directory. However, this is not recommended for production databases.

To create the Oracle base directory:

1. Enter the following command to display information about all mounted file systems:

# df -h

This command displays information about all the file systems mounted on the system, including:

- The physical device name

- The total amount, used amount, and available amount of disk space

- The mount point directory for that file system

2. From the display, identify either one or two file systems that meet the disk space requirements mentioned earlier in this section.

3. Note the name of the mount point directory for each file system that you identified.

4. Enter commands similar to the following to create the recommended subdirectories in the mount point directory that you identified and set the appropriate owner, group, and permissions on them:

# mkdir -p /mount_point/app/
# chown -R oracle:oinstall /mount_point/app/
# chmod -R 775 /mount_point/app/

For example:

# mkdir -p /u01/app/
# chown -R oracle:oinstall /u01/app/
# chmod -R 775 /u01/app/

7 Configuring the oracle User's Environment

You run Oracle Universal Installer from the oracle account. However, before you start Oracle Universal Installer, you must configure the environment of the oracle user. To configure the environment, you must:

- Set the default file mode creation mask (umask) to 022 in the shell startup file.

- Set the DISPLAY environment variable.

To set the oracle user's environment:

1. Start a new terminal session, for example, an X terminal (xterm).

2. Enter the following command to ensure that X Window applications can display on this system:

$ xhost fully_qualified_remote_host_name

For example:

$ xhost somehost.us.example.com

3. If you are not logged in to the system where you want to install the software, then log in to that system as the oracle user.

4. If you are not logged in as the oracle user, then switch user to oracle:

$ su - oracle

5. To determine the default shell for the oracle user, enter the following command:

$ echo $SHELL

6. To run the shell startup script, enter one of the following commands:

- Bash shell:

$ . ./.bash_profile

- Bourne or Korn shell:

$ . ./.profile

- C shell:

% source ./.login

7. If you are not installing the software on the local computer, then run the following command on the remote computer to set the DISPLAY variable:

- Bourne, Bash or Korn shell:

$ export DISPLAY=local_host:0.0

- C shell:

% setenv DISPLAY local_host:0.0

In this example, local_host is the host name or IP address of the local computer to use to display Oracle Universal Installer.

Run the following command on the remote computer to check if the shell and the DISPLAY environmental variable are set correctly:

echo $SHELL
echo $DISPLAY

Now to enable X applications, run the following commands on the local computer:

$ xhost + fully_qualified_remote_host_name

To verify that X applications display is set properly, run a X11 based program that comes with the operating system such as xclock:

$ xclock

In this example, you can find xclock at /usr/X11R6/bin/xclocks. If the DISPLAY variable is set properly, then you can see xclock on your computer screen.

PC-X Server or operating system vendor documents for further assistance

8. If you determined that the /tmp directory has less than 1 GB of free disk space, then identify a file system with at least 1 GB of free space and set the TMP and TMPDIR environment variables to specify a temporary directory on this file system:

1. To determine the free disk space on each mounted file system use the following command:

# df -h /tmp

2. If necessary, enter commands similar to the following to create a temporary directory on the file system that you identified, and set the appropriate permissions on the directory:

$ sudo mkdir /mount_point/tmp
$ sudo chmod a+wr /mount_point/tmp
# exit

3. Enter commands similar to the following to set the TMP and TMPDIR environment variables:

- Bourne, Bash, or Korn shell:

$ TMP=/mount_point/tmp
$ TMPDIR=/mount_point/tmp
$ export TMP TMPDIR

- C shell:

% setenv TMP /mount_point/tmp
% setenv TMPDIR /mount_point/tmp

9. Enter commands similar to the following to set the ORACLE_BASE and ORACLE_SID environment variables:

- Bourne, Bash, or Korn shell:

$ ORACLE_BASE=/u01/app/oracle
$ ORACLE_SID=sales
$ export ORACLE_BASE ORACLE_SID

- C shell:

% setenv ORACLE_BASE /u01/app/oracle
% setenv ORACLE_SID sales

In this example, /u01/app/oracle is the Oracle base directory that you created or identified earlier and sales is the database name (typically no more than five characters).

10. Enter the following commands to ensure that the ORACLE_HOME and TNS_ADMIN environment variables are not set:

- Bourne, Bash, or Korn shell:

$ unset ORACLE_HOME
$ unset TNS_ADMIN

- C shell:

% unsetenv ORACLE_HOME
% unsetenv TNS_ADMIN

Note:
If the ORACLE_HOME environment variable is set, then Oracle Universal Installer uses the value that it specifies as the default path for the Oracle home directory. However, if you set the ORACLE_BASE environment variable, then Oracle recommends that you unset the ORACLE_HOME environment variable and choose the default path suggested by Oracle Universal Installer.

8 Mounting the Product Disc

On most Linux systems, the product disc mounts automatically when you insert it into the drive. If the disc does not mount automatically, then follow these steps to mount it:

1. Enter a command similar to the following to eject the currently mounted disc, then remove it from the drive:

- Asianux, Oracle Linux, and Red Hat Enterprise Linux:

$ sudo eject /mnt/dvd

- SUSE Linux Enterprise Server:

# eject /media/dvd

In these examples, /mnt/dvd and /media/dvd are the mount point directories for the disc drive.

2. Insert the DVD into the disc drive.

3. To verify that the disc mounted automatically, enter a command similar to the following:

- Asianux, Oracle Linux, and Red Hat Enterprise Linux:

# ls /mnt/dvd

- SUSE Linux Enterprise Server:

# ls /media/dvd

4. If this command fails to display the contents of the disc, then enter a command similar to the following:

- Asianux, Oracle Linux, and Red Hat Enterprise Linux:

# mount -t iso9660 /dev/dvd /mnt/dvd

- SUSE Linux Enterprise Server:

# mount -t iso9660 /dev/dvd /media/dvd

In these examples, /mnt/dvd and /media/dvd are the mount point directories for the disc drive.

9 Installing Oracle Database Client

In the Software Location section, accept the default value or enter the Oracle home directory path in which you want to install Oracle components. The directory path should not contain spaces. Click Next.

7. In the Create Inventory screen, you are prompted by the installer to specify the directory path for central inventory the first time you install Oracle software on your computer. Select the oraInventory Group Name of the operating system group that should own the Oracle Inventory directory (the Oracle Inventory group), and click Next.

Note:
By default, the Oracle Inventory directory is not installed under the Oracle Base directory. This is because all Oracle software installations share a common Oracle Inventory, so there is only one Oracle Inventory for all users, whereas there is a separate Oracle Base for each user.

8. The Perform Prerequisite Checks screen verifies if your computer meets the minimum system requirements to install the desired product. Click Next.
Note: Oracle recommends that you use caution in checking the Ignore All option. If you check this option, then Oracle Universal Installer may not confirm if your system can install Oracle Database successfully.

9. Review the information displayed in the Summary screen, and click Finish.

Note:
Starting with Oracle Database 11g Release 2 (11.2), you can save all the installation steps into a response file by clicking Save Response File. Later, this file can be used for a silent installation.

10. The Install Product screen states the progress of a client installation. After Oracle Database Client is installed, you are prompted to execute the root configuration script for new inventory as a root user. Execute the root.sh script as a root user to complete the installation, and click OK.

11. In the Finish screen, click Close to exit from Oracle Universal Installer.
