Hardware Component Requirements for Windows x64

The following table lists the hardware components that are required for Oracle Database Client on Windows x64.

Table 3-1 Windows x64 Hardware Requirements

Requirement	Value
System Architecture	Processor: AMD64 and Intel EM64T
Physical memory (RAM)	2 GB minimum
Virtual memory (swap)	Double the amount of RAM
Disk space	Total ranges from 430 - 1570 MB
Video adapter	256 colors
Screen Resolution	1024 X 768 minimum

Note:

Oracle provides 32-bit and 64-bit versions of Oracle Database Client for Windows. Oracle certifies 32-bit Oracle Database Client running on Windows x64 only.

Hard Disk Space Requirements

Oracle strongly recommends that you install the Oracle database home (Oracle database binaries, trace files, and so on) on Oracle Automatic Storage Management Cluster File System (Oracle ACFS) or New Technology File System (NTFS).

The database files must be placed on Oracle Automatic Storage Management (Oracle ASM) if using Oracle ACFS or on NTFS. Oracle recommends usage of Oracle ACFS and Oracle ASM or NTFS to ensure security of these files.

The NTFS system requirements listed 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 includes space to install Java Runtime Environment (JRE) and Oracle Universal Installer on the partition where the operating system is installed. If sufficient space is not available, the installation fails and an error message appears.

The following table lists the disk space requirements on NTFS. The values in this table include the starter database.

Table 3-2 Windows x64 Disk Space Requirements on NTFS

Installation Type	TEMP Space	Directory:\ Program Files\Oracle\Inventory	Oracle Home	Total
Instant Client	136 MB	166 KB	361 MB	485 MB
Administrator	140 MB	1.6 MB	1.85 GB	1635 MB
Runtime	130 MB	1.55 MB	1.35 GB	1235 MB
Custom (all components installed)	145 MB	2.0 MB *	1.86 GB *	1635 MB *

* Disk space requirements vary, depending on the components selected.

Note:

If you want to configure only the Instant Client Light component of Instant Client, then you need 30–32 MB of disk space to store the related files.

Verifying Hardware Requirements

Use this procedure to verify your server configuration requirements.

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

1. Determine the physical RAM size.

   For example, on a computer running Windows Server 2012 R2, click System and Security, 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.

2. Determine the size of the configured virtual memory (also known as paging file size).

   For example, on a computer running Windows Server 2012 R2, 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.

3. Determine the amount of free disk space on the system.

   For example, on a computer running Windows Server 2012 R2, right-click My Computer and click Open.

4. Determine the amount of disk space available in the temp directory. This is equivalent to the total amount of free disk space, minus what is required for the Oracle software to be installed.

   On Windows x64, 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 TEMP or TMP environment variable to point to a different hard drive location.

   For example, to change the environment variables on a computer running Windows Server 2012 R2, click System and Security, then click System, click Advanced System Settings, click the Advanced tab on System Properties page, and then click Environment Variables.
