This chapter describes the different installation types of Oracle Database Client for Linux and issues to consider before you install Oracle Database Client:
The Oracle Database installation process consists of the following phases:
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:
http://www.oracle.com/technology/documentation
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.

Oracle Database Licensing InformationPlan 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.
Complete preinstallation tasks: Chapter 2 describes preinstallation tasks that you must complete before installing the product.
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 A provides information on performing silent installations, which you may want to use if you must perform multiple installations of Oracle Database Client.
Appendix B describes globalization support information.
Appendix C provides troubleshooting advice in case you encounter problems with the installation.
Complete postinstallation tasks: Chapter 4 describes recommended and required postinstallation tasks.
This section contains information that you should consider before deciding how to install this product. It contains the following sections:
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:
http://metalink.oracle.com/
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.
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.
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.
Starting with Oracle Database 11g Release 2 (11.2), 64-bit client shiphomes will not contain any 32-bit client binaries. If you require 32-bit client binaries on 64-bit ports, then you can install the 32-bit binaries from the respective 32-bit client shiphome.
You can choose different installation methods to install Oracle Database Client, as follows:
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.
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 A.
You can choose one of the following installation types when installing Oracle Database Client:
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 than the other Oracle Database Client installation types.
See Also:
Oracle Call Interface Programmer's Guide or Oracle Database JDBC Developer's Guide for more information about Instant ClientIncluded in the Instant Client installation is Instant Client Light. You may want to use this version of Instant Client if the applications generate error messages in American English only. Instant Client Light is beneficial to application that use one of the supported character sets and can accept error messages in American English. The following are the supported character sets:
US7ASCII
WE8DEC
WE8ISO8859P1
WE8EBCDIC37C for EBCDIC platform only
WE8EBCDIC1047 for EBCDIC platform only
WE8MSWIN1252
UTF8
AL32UTF8
AL16UTF16
The advantage of using Instant Client Light is that it has a smaller footprint than the regular Instant Client. The shared libraries, which an application must load, are only 34 MB as opposed to the 110 MB that regular Instant Client uses. Therefore, the applications use less memory.
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.
Custom: Enables you to select individual components from the list of Administrator and Runtime components.
For information about upgrading an earlier release of Oracle Database to Oracle Database 11g Release 2 (11.2), refer to Oracle Database Upgrade Guide. The following section provides additional upgrade information that you should review before upgrading an existing database.
When time zone version files are updated due to Daylight Saving Time changes, TIMESTAMP WITH TIMEZONE (TSTZ) data could become stale. In previous releases, database administrators ran the SQL script utltzuv2.sql to detect TSTZ data affected by the time zone version changes and then had to carry out extensive manual procedures to update the TSTZ data.
With this release, TSTZ data is updated transparently with very minimal manual procedures using newly provided DBMS_DST PL/SQL packages. In addition, there is no longer a need for clients to patch their time zone data files.
