ORACLE 11g R2 Database installation hardware environment requirements

Physical memory requirements: Minimum 1G, minimum 2G on windows7,windows8,windows8.1.

Virtual memory (or paging space) capacity requirements:

Available RAM	Swap Space Required
Between 2GB and 16GB	Equal to the size of RAM
More than GB	16GB

Database software hard disk space requirements:

Installation Type	Requirement for software files
TEMP Space	500MB
C:\ProgramFiles\Oracle	4MB
Enterprise Edition	3.80GB
Standard Edition	3.88GB

Minimum hard disk space requirements for database files:

Installation Type	Requirement for data files (GB)
Enterprise Edition	1.9
Standard Edition	1.5

Build environment: Windows Server Enterprise R2 +oracle 11g R2

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

1, confirm the physical memory size.

2. Determine the configured virtual memory (paging space) size.

For example, on WINSERVER2008R2, click on "System and security--system--Advanced system settings--advanced----and advanced--" to see the virtual memory size. If necessary, check the operating system for document information about how to adjust additional virtual memory to make adjustments.

3. Confirm the free hard disk space in the system (Oracle_home is recommended to be installed on a disk other than the C drive).

4, confirm the temporary folder (C Disk Temp folder) can occupy the size of hard disk space, if less than 500M, first clean up all unnecessary files, such as the temp hard disk space is still less than 500MB, then set TEMP, TMP directory point to the new disk (in the environment variable-- Modified in the Administrator environment variable).

In this set up environment, winServer2008 installed after the installation of the C disk space of about 16G, plus the need to configure virtual memory space, plus temp (500M), etc., it is recommended to build Oracle 11g for the Database environment project, The C-drive space is guaranteed to be above 40G (depending on the situation).

It is recommended that when building a project with Oracle 11g as a database environment, in order to ensure the performance of database operation, it is recommended that server memory is at least 4g-8g, depending on the business requirements 4g-32g as memory parameters for server selection.
