For information about obtaining a stand-alone Engine installer, see Obtaining the Installer.Įdit the \Server\processMonitorConfigEngines.txt file: The default installation directory for a 32-bit engine is C:\apps\FME. Run the stand-alone (Engine Only) FME Engine installer and note the default installation directory. To Install a Different Bit Version of an FME Engine on the Same Machine
Note: A 64-bit engine will not run on a 32-bit version of Windows. Run the same bit version of FME Engines unless absolutely necessary. WARNING: This procedure limits the ability to configure FME Engines on the Engines page of the Web User Interface. For example, you may currently be running only 64-bit engines, but you want to run a workspace from FME Server containing a format that runs only on a 32-bit engine. In some cases, you may want to install 32-bit and 64-bit FME Engines on the same machine. 64 bits isn't currently much of a reason to select one or the other.Installing 32- and 64-bit Engines on the Same Machine There are theoretical performance advantages to a 64 bit systems caused by more registers, wider memory fetches (that is, more bits read per read operation), and so forth, but the data I've seen so far suggests that performance of 32 vs. This article from AMD (warning: PDF) discusses 64-vs-32 bits in some detail. The varnish http cache is a prime example of this. This affects not just "real ram", but their entire virtual address space.which is a particular problem if applications plan to make extensive use of virtual memory via mmap() or other techniques. While you can get your 32bit kernel to address more than 4GB of RAM, individual processes will still be limited to 4GB. The biggest is, as you say, the ability to address large amounts of memory. There are a number of advantages to running in a 64 bit environment.
Are there any benefits or disadvantages between 64-bit and 32-bit virtualization, except theĤ gigabyte memory limit on 32-bit machines.
