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.

See Also:
Oracle Call Interface Programmer's Guide for more information about Instant Client

This guide does not describe how to install the Custom installation type. It also does not describe how to perform an in-place client upgrade.

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 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 Configuring Servers for Oracle Database

This section describes the following operating system tasks you must complete before you install Oracle Database:

- Checking Server Hardware and Memory Configuration

- General Server Minimum Requirements

- Server Storage Minimum Requirements

- Server Memory Minimum Requirements

- Hardware Requirements for SQL Developer

3.1 Checking Server Hardware and Memory Configuration

Run the following commands to check your current system information:

1. To determine the physical RAM size, enter the following command:

# grep MemTotal /proc/meminfo

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

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

# grep SwapTotal /proc/meminfo

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

3. To determine the amount of space available in the /tmp directory, enter the following command:

# df -h /tmp

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

# df -h

5. To determine the amount of free RAM and disk swap space on the system, enter the following command:

# free

6. To determine if the system architecture can run the software, enter the following command:

# uname -m

If you do not see the expected output, then you cannot install the software on this system.

3.2 General Server Minimum Requirements

Ensure the following general minimum requirements on your system:

- Ensure that the system is started with runlevel 3 or runlevel 5.

- Ensure display cards provide at least 1024 x 768 display resolution, so that Oracle Universal Installer displays correctly while performing a system console-based installation

3.3 Server Storage Minimum Requirements

Ensure that your system meets the following minimum storage requirements:

- Ensure that your IBM: Linux on System z meets the disk space requirements for software files as described in Table 1:

https://support.oracle.com

See Also:
Oracle Enterprise Manager Cloud Control Basic Installation Guide for steps on how to access the Enterprise Manager certification matrix

8 Checking the Software Requirements

To ensure that the system meets these requirements, follow these steps:

1. To determine the distribution and version of Linux installed, enter one of the following commands:

# lsb_release -id

2. To determine whether the required kernel errata is installed, enter the following command:

# uname -r

Review the required errata level for your distribution. If the errata level is previous to the required minimum errata update, then obtain and install the latest kernel update from your Linux distributor.

3. To determine whether the required packages are installed, enter commands similar to the following:

# rpm -q package_name

Alternatively, if you require specific system architecture information, then enter the following command:

# rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep package_name

You can also combine a query for multiple packages, and review the output for the correct versions. For example:

# rpm -q binutils compat-libstdc++ gcc glibc libaio libgcc libstdc++ \
make sysstat unixodbc

If a package is not installed, then install it from your Linux distribution media or download the required package version from your Linux distributor's website.

9 Separate 32-Bit Client Software for 64-Bit Platforms

The 64-bit Oracle Database Client software does not contain any 32-bit client binaries. If you require 32-bit client binaries on 64-bit platforms, then install the 32-bit binaries from the respective 32-bit client software into a separate Oracle home.

The 64-bit Oracle Database Client preinstallation requirements apply to 32-bit Oracle Database Client also.

See Also:
My Oracle Support note 883702.1 for more information:
https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=883702.1

10 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 a command similar to the following to modify it:

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

Specify the primary group using the -g option and any required secondary group using the -G option.

Note:
Oracle does not support modifying existing Oracle Database server or other Oracle software installation owners. Oracle only supports modifying an Oracle Database Client software owner.

- 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

11 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/

12 Configuring Oracle Software Owner 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.

Caution:
Use shell programs supported by your operating system vendor. If you use a shell program that is not supported by your operating system, then you can encounter errors during installation.

To set the oracle user's environment:

1. Start a new X terminal session (xterm).

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

$ xhost + RemoteHost

where RemoteHost is the fully qualified remote host name. For example:

$ xhost + somehost.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 system, then enter a command similar to the following to direct X applications to display on the local system:

- Bourne, Bash, or Korn shell:

$ 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 system to use to display Oracle Universal Installer (your workstation or PC).

8. If you determined that the /tmp directory has less than 400 MB of free disk space, then identify a file system with at least 400 MB 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 -k

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. If you have had an existing installation on your system, and you are using the same user account to install this installation, then unset the ORACLE_HOME, ORACLE_BASE, ORACLE_SID, TNS_ADMIN environment variables and any other environment variable set for the Oracle installation user that is connected with Oracle software homes.
Enter the following commands to ensure that the ORACLE_HOME, ORACLE_BASE, ORACLE_SID and TNS_ADMIN environment variables are not set:

- Bourne, Bash, or Korn shell:

$ unset ORACLE_HOME
$ unset ORACLE_BASE
$ unset ORACLE_SID
$ unset TNS_ADMIN

- C shell:

% unsetenv ORACLE_HOME
% unsetenv ORACLE_BASE
% unsetenv ORACLE_SID
% unsetenv TNS_ADMIN

Use the following command to check the PATH environment variable:

$ echo $PATH

Ensure that the $ORACLE_HOME/bin path is removed from your PATH environment variable.

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. 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.

10. To verify that the environment has been set correctly, enter the following commands:

$ umask
$ env | more

Verify that the umask command displays a value of 22, 022, or 0022 and the environment variables that you set in this section have the correct values.

13 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:

- 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:

- 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:

- 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.

14 Installing Oracle Database Client

After configuring the oracle user's environment, start Oracle Universal Installer and install Oracle Database Client as follows:

- Log on as the Oracle software owner user (typically, oracle) to the computer on which to install Oracle components.

- If you are installing the software from installation media, then mount the disk if it is not mounted.

- To start Oracle Universal Installer, enter the following command:

$ /directory_path/runInstaller

If the installation files are on the hard disk, change to the client directory and enter the following command:

$ ./runInstaller

If Oracle Universal Installer is not displayed, then refer to Oracle Database Client Installation Guide for Linux for information about how to troubleshoot X Window display problems.

- The following table describes the recommended action for each Oracle Universal Installer screen. Use the following guidelines to complete the installation:

- If you need more assistance, or to choose an option that is not a default, click Help for additional information.

- If you encounter errors while installing or linking the software, then refer to Oracle Database Installation Guide for information about troubleshooting.

Note:
If you have completed the tasks listed previously, then you can complete the installation by choosing the default values on most screens.

1. If you have an existing Oracle Database Client 12c Release 1 (12.1.0.1) or later installed on your system, the Select Installation Mode screen is displayed. Select New Install to install Oracle Database Client software in a new location, or select Upgrade and follow the instructions in the "Performing an In-place Oracle Database Client Upgrade" section in Oracle Database Client Installation Guide for Linux to upgrade an earlier release of Oracle Database Client.

2. In the Select Installation Type screen, select the type of installation: Instant Client, Administrator, or Runtime and click Next.

3. The Select Product Languages screen enables you to select the language in which you want to run the product.
Select the product language from the Available Languages list, transfer it to the Selected Languages list. Click Next.

This screen is not displayed if you select Instant Client as the type of installation in Step 2.

4. In the Specify Installation Location screen, enter the following details:
Oracle Base: This path appears by default. You can change the path based on your requirement. The Oracle Base section is not displayed if you select Instant Client as the type of installation in Step 2.

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.

5. 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.

6. 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.

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

Note:
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.

8. The Install Product screen states the progress of a client installation. After Oracle Database Client is installed, execute the root.sh script as a root user to complete the installation, and click OK.

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

15 What to Do Next?

After you have successfully installed Oracle Database Client, refer to Oracle Database Client Installation Guide for Linux for information about required and optional postinstallation steps.
