1 Overview of Oracle Database Client Installation

This chapter describes the different installation types of Oracle Database Client and issues to consider before you install Oracle Database Client on Linux:

1.1 Planning Your Installation

The Oracle Database installation process consists of the following phases:

  1. Read the release notes: Read Oracle Database Release Notes for Linux before you begin the installation. The release notes are available with the platform-specific documentation. The latest version of the release notes is available on Oracle Technology Network at:
  2. Review the licensing information: Although the installation media in your media pack contain many Oracle components, you are permitted to use only those components for which you have purchased licenses.

    Oracle Support Services does not provide support for components for which licenses have not been purchased.

  3. Plan the installation: This chapter describes the Oracle products that you can install and issues that you must consider before starting the installation.

    You can also refer to Appendix D, which covers frequently asked questions about installing Oracle Database components, such as how to install Oracle Database Client if the site uses Oracle applications or if you need multiple Oracle Database Client connections.

  4. Complete preinstallation tasks: Chapter 2 describes preinstallation tasks that you must complete before installing the product.

  5. Install the software: Use the following sections to install Oracle Database:

    • Chapter 3 describes how to use Oracle Universal Installer to install Oracle Database Client.

    • Appendix B provides information on performing silent installations, which you may want to use if you must perform multiple installations of Oracle Database Client.

    • Appendix A describes globalization support information.

    • Appendix C provides troubleshooting advice in case you encounter problems with the installation.

  6. Complete postinstallation tasks: Chapter 4 describes recommended and required postinstallation tasks.

1.2 Installation Considerations

This section contains information that you should consider before deciding how to install this product. It contains the following sections:

1.2.1 Hardware and Software Certification

The platform-specific hardware and software requirements included in this installation guide were current at the time this guide was published. However, because new platforms and operating system software versions might be certified after this guide is published, review the certification matrix on the My Oracle Support (formerly OracleMetaLink) Web site for the most up-to-date list of certified hardware platforms and operating system versions. The My Oracle Support (formerly OracleMetaLink) Web site is available at the following URL:

You must register online before using My Oracle Support (formerly OracleMetaLink). After logging in, click Certify from the top right-hand side of the screen. The Certifications page appears. Other options include Product Availability, Desupport Notices, and Alerts.

1.2.2 Multiple Oracle Homes Support

This product supports multiple Oracle homes. This means that you can install this release or earlier releases of the software more than once on the same system, in different Oracle home directories. Installing the Software on a System with an Existing Oracle Installation

You must install this product into a new Oracle home directory. You cannot install products from one release of Oracle Database into an Oracle home directory of a different release. For example, you cannot install release 11.2 software into an existing Oracle9i Oracle home directory. If you attempt to install this release into an Oracle home directory that contains software from an earlier Oracle release, then the installation fails.

Oracle Database Client can be installed in the same Oracle Database home if both products are at the same release level. For example, you can install Oracle Database Client 11g Release 2 (11.2) into an existing Oracle Database 11g Release 2 (11.2) home. If you apply a patch set before installing the client, then you must apply the patch set again.

You can install this release more than once on the same system if each installation is installed in a separate Oracle home directory.

1.2.3 Separate 32-Bit Client Software for 64-Bit Ports

Refer to "Separate 32-Bit Client Software for 64-Bit Ports" for more information.

1.3 Oracle Database Client Installation Methods

You can choose different installation methods to install Oracle Database Client, as follows:

1.3.1 Interactive Installation Methods

When you use the interactive method to install Oracle Database Client, Oracle Universal Installer displays a series of screens that enable you to specify all of the required information to install the Oracle Database Client software.

1.3.2 Automated Installation Methods Using Response Files

By creating a response file and specifying this file when you start Oracle Universal Installer, you can automate some or all of the Oracle Database installation. These automated installation methods are useful if you must perform multiple installations on similarly configured systems or if the system where you want to install the software does not have X Window system software installed.

When you use a response file, you can run Oracle Universal Installer in the following modes, depending on whether you specify all of the required information or not:

  • Silent Mode: Oracle Universal Installer runs in silent mode if you use a response file that specifies all required information, and specify the -silent option when starting Oracle Universal Installer. None of the Oracle Universal Installer screens are displayed.

  • Response File Mode: Oracle Universal Installer runs in response file mode if you do not specify all required information in the response file.

For more information about these modes and about how to complete an installation using response files, refer to Appendix B.

1.4 Oracle Database Client Installation Types

You can choose one of the following installation types when installing Oracle Database Client:

1.5 Oracle Database Client and Oracle Database Interoperability

For information about interoperability between Oracle Database Client and Oracle Database releases, see Note 207303.1 on the My Oracle Support (formerly OracleMetaLink) Web site at the following URL:

1.6 Simplified Patching of Timestamp with Time Zone Data Type

Starting with Oracle Database 11g Release 2 (11.2), the patching process of TIMESTAMP WITH TIMEZONE data type values is simplified.
