Does Esri support 64-bit processors with ArcGIS 10.0 products?
Support for 64-bit processors/operating systems
ArcGIS 10.0 on Windows is supported on 64-bit processors and operating systems. In addition to Windows, ArcReader Standalone is supported on a Solaris 64-bit environment running as a 32-bit application. ArcReader 10.0 on 64-bit Linux is supported on Red Hat Enterprise Linux (RHEL) 4, (RHEL) 5, and SuSE 10.
ArcGIS Desktop on 64-bit
ArcGIS Desktop 10.0 applications are natively 32-bit applications but take advantage of a technology known as large memory awareness. This means that individual processes, such as ArcMap.exe, may be capable of accessing more than 2GB of memory (up to 4GB) when run on a 64-bit OS. Note that some functionality and third-party libraries that are part of ArcGIS are not compatible with large-address-awareness, and as such, some portions of ArcGIS may not be able to address more than 2GB even when running on a 64-bit OS.
Terminal Server Support for 64-bit operating systems
Terminal serving technologies running on 64-bit operating systems are able to provide ArcGIS Desktop applications with up to a 4GB address space.
ArcInfo Workstation on 64-bit
ArcInfo Workstation is a native 32-bit application and runs as a 32-bit application on 64-bit (x64) Microsoft Windows.
ArcGIS Server and ArcIMS on 64-bit
ArcGIS Server for .NET and Java and ArcIMS are native 32-bit applications. They are both certified running as 32-bit applications on 64-bit (x64) Microsoft Windows. Web server support is based on the Web server vendor’s support of 64-bit Microsoft Windows. Check with the Web server vendor to determine if the Web server is supported on 64-bit Microsoft Windows.
In addition to Windows, ArcGIS Server for Java and ArcIMS are supported on a 64-bit Solaris environment. ArcGIS Server for Java and ArcIMS are supported on a 64-bit Linux environment.
ArcGIS Server for .Net and Java and ArcIMS are compiled to be large memory aware, meaning that on a 64-bit Windows operating system they can use the full 4GB address space accessible to 32-bit applications.
The ArcGIS Server Java ADF runtime is supported on both the 32-bit and the 64-bit Java Runtime Environments.
Esri will continue to support the ArcSDE technology component of ArcGIS Server on 64-bit Solaris environments in releases beyond 10.0.
