Client Quick Installation Guide
11g Release 2 (11.2) for Microsoft Windows (32-Bit)
This guide describes how to quickly install the Oracle Database Client product on 32-bit Windows systems. It includes information about the following:
Note:This guide describes how to install Oracle Database Client on a system that does not have any Oracle software installed on it. If there is an existing Oracle software installation on this system, see Oracle Database Client Installation Guide for Microsoft Windows for more detailed installation instructions.
This guide describes how to complete a default installation of Oracle Database Client that does not have any Oracle software installed on it. It describes how to install one of the following installation types:
Instant Client: Enables you to install only the shared libraries required by Oracle Call Interface applications that use the Instant Client feature. This installation type requires much less disk space than the other Oracle Database Client installation types.
Instant Client includes Instant Client Light. You may want to use this version of Instant Client if your applications generate error messages in American English only. The advantage of using Instant Client Light is that it has a smaller footprint than regular Instant Client. Hence, your applications use less memory.
Administrator: Enables applications to connect to an Oracle database on the local system or on a remote system. It also provides tools that let you administer an Oracle database.
Runtime: Enables applications to connect to an Oracle database on the local system or on a remote system.
See Also:Oracle Call Interface Programmer's Guide for more information about the Instant Client feature
This guide does not describe how to install the Custom installation type.
For more detailed information about installing Oracle Database Client, see Oracle Database Client Installation Guide for Microsoft Windows.
The product documentation for Oracle Database products is available in both HTML and PDF formats online on the Oracle Technology Network (OTN) website:
Table 1 lists the required hardware components for Oracle Database Client.
Physical memory (RAM)
512 MB minimum, 1 GB recommended
On Windows 7, Windows 8, and Windows 8.1, 1 GB minimum
Double the amount of RAM
Hard disk space
Total ranges between 300–1160 MB. See Table 2 for details.
Intel (x86), AMD64, and Intel EM64T
1024 X 768 minimum
This section lists system requirements for Windows platforms that use the NT File System (NTFS). Oracle strongly recommends that you install the Oracle database home (Oracle database binaries, trace files, and so on) on Oracle ACFS or NTFS; the database files themselves must be placed on Oracle ASM if using Oracle ACFS; otherwise they can be placed on NTFS. Usage of Oracle ACFS and Oracle ASM or NTFS instead of FAT32 is recommended to ensure security of these files.
The NTFS system requirements listed in this section are more accurate than the hard disk values reported by the Oracle Universal Installer Summary window. The Summary window does not include accurate values for disk space, the space required to create a database or the size of compressed files that are expanded on the hard drive.
The hard disk requirements for Oracle Database Client components include space required to install Java Runtime Environment (JRE) and Oracle Universal Installer on the partition where the operating system is installed. If sufficient space is not detected, then installation fails and an error message appears.
Table 2 lists the disk space requirements on NTFS.
|Installation Type||TEMP Space||SYSTEM_DRIVE:\Program Files\Oracle\Inventory||Oracle Home||Total|
Custom (all components installed)
1.20 GB *
1155.1 MB *
* Disk space requirements vary, depending on the components selected.
See Also:"NTFS File System and Windows Registry Permissions" in Oracle Database Platform Guide for Microsoft Windows
To ensure that the system meets these requirements, follow these steps:
Determine the physical RAM size. For example, on a Windows 2003 computer, double-click System in the Windows Control Panel and select the General tab.
On a Windows Server 2008 R2 computer, click System and Security in the Windows Control Panel, then click System.
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.
Determine the size of the configured virtual memory (also known as paging file size). For example, on a Windows 2003 computer, double-click System, click the Advanced tab, and click Settings in the Performance section. Then select the Advanced tab.
On a Windows Server 2008 R2 computer, click System and Security, then click System, click Advanced System Settings, click the Advanced tab on System Properties page, and then click Settings in the Performance section. Then select the Advanced tab on Performance Options page.
The virtual memory is listed in the Virtual Memory section.
If necessary, see your operating system documentation for information about how to configure additional virtual memory.
Determine the amount of free disk space on the system. For example, on a Windows 2003 computer, double-click My Computer, right-click the drive where the Oracle software is to be installed, and select Properties.
On a Windows Server 2008 R2 computer, right-click My Computer and click Open.
Determine the amount of disk space available in the
temp directory. This is equivalent to the total amount of free disk space, minus what will be needed for the Oracle software to be installed.
If there is less than 130 MB of disk space available in the
temp directory, then delete all unnecessary files. If the temp disk space is still less than 130 MB, then set the
TMP environment variable to point to a different hard drive location.
For example, to change the environment variables on a Windows Server 2003 computer, double-click System, click the Advanced tab, and click Environment Variables
On a Windows Server 2008 R2 computer, click System and Security, then click System, click Advanced System Settings, click the Advanced tab on System Properties page, and then click Environment Variables.
Table 3 lists the software requirements for Oracle Database Client.
Oracle Database Client for Windows is supported on the following operating systems:
Windows Multilingual User Interface Pack is supported.
The Server Core option is not supported for all Windows Server operating systems.
Note: For information about Hyper-V support, visit My Oracle Support (formerly OracleMetaLink) at
Pro*Cobol has been tested and certified with Net Express 5.0.
The following components are supported with the Microsoft Visual C++ .NET 2005 8.0, Microsoft Visual C++ .NET 2008 9.0. and Intel 10.1 C compilers:
Oracle C++ Call Interface is supported with
The Oracle Net foundation layer uses Oracle protocol support to communicate with the following industry-standard network protocols:
In addition to the requirements described in the previous section, if you plan to use Instant Client Light, the applications must use the following languages and character sets:
Language: Any language that is supported by Oracle, but only US English error messages are returned for errors generated on the client side.
Territory: Any territory that is supported by Oracle.
Instant Client Light can connect to databases having one of the following database character sets. An error is returned if a character set other than those in the list is used as the client or database character set.
Instant Client Light can also operate with the OCI Environment handles created in the OCI_UTF16 mode.
The language, territory, and character sets are determined by the
NLS_LANG parameter, which is stored in the registry under the
\NLS_LANG subkey, where
HomeName is the unique name identifying the Oracle home.
Caution:AL32UTF8 is the Oracle Database character set that is appropriate for XMLType data. It is equivalent to the IANA registered standard UTF-8 encoding, which supports all valid XML characters.
Do not confuse Oracle Database database character set UTF8 (no hyphen) with database character set AL32UTF8 or with character encoding UTF-8. Database character set UTF8 has been superseded by AL32UTF8. Do not use UTF8 for XML data. UTF8 supports only Unicode version 3.1 and earlier; it does not support all valid XML characters. AL32UTF8 has no such limitation.
Using database character set UTF8 for XML data could potentially cause an irrecoverable error or affect security negatively. If a character that is not supported by the database character set appears in an input-document element name, a replacement character (usually "?") is substituted for it. This terminates parsing and raises an exception.
Oracle Enterprise Manager supports the following browsers:
Netscape Navigator 9.0
Netscape Navigator 8.1
Microsoft Internet Explorer 10.0 (supports Oracle Enterprise Manager Database Control 126.96.36.199 or higher)

The following sections describe how to install the Oracle software:
On Windows Vista, Windows Server 2008, Windows Server 2008 R2, Windows 7, and Windows 8, and Windows 8.1, command prompts should be opened with Administrator privileges.
In most cases, you use the graphical user interface (GUI) provided by Oracle Universal Installer to install Oracle Database Client. However, you can also use Oracle Universal Installer to complete silent or noninteractive installations using a response file, without using the GUI. This method is particularly useful if you need to perform multiple installations of Oracle Database Client.
As you install Oracle Database Client, follow these guidelines:
See Also:Appendix B, "Installing Oracle Database Client Using Response Files" in Oracle Database Client Installation Guide for Microsoft Windows for information about silent or response file mode installations
Do not use Oracle Universal Installer from an earlier Oracle product release to install components from this release.
Use the same installation media to install Oracle Database Client on all supported Windows platforms.
If you reinstall Oracle software into an Oracle home directory where Oracle Database Client is already installed, you must reinstall any components that were installed before you began the reinstallation.
Do not modify the Java Runtime Environment (JRE) except by using a patch provided by Oracle Support Services. Oracle Universal Installer automatically installs the Oracle-supplied version of the JRE. This version is required to run Oracle Universal Installer and several Oracle assistants.
