Hi,

If Windows is using all the memory, what will Oracle use?

Why do you want Windows to use all the memory?

Regards

Windows is using the complete 12 GB of memory as indicated in screenshot 1. The 8 GB is the amount Windows has allocated at the moment to the system cache. You should check the memory settings for the Oracle database system, if you suspect that the database isnn't using enough memory.<br />
<br />
Why do you keep your pagefile so small? In your situation you could easily go with system managed or allow 12 GB on drive C:. <br />
<br />
For some more info about that all look at this KB article <a href="http://support.microsoft.com/kb/2160852/en-us" rel="ugc">http://support.microsoft.c<wbr />om/kb/2160<wbr />852/en-us</a>

We have Oracle 11 g database in windows 2003 R2 server(64bit), RAM is 12gb, but windows is using only 8gb i think. 
How to use the 12gb completely

Windows 2003 R2 server memory management

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.

Microsoft Legacy OS

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.
