We have a 32 bit application. It is currently running on a 32 VM. If we run the application on a 64 bit OS(Virtual Machine) which supports Intel Virtualization Technology will it run faster? We do not have a 32 bit OS(Virtual Machine) which supports Intel Virtualization Technology.
There is not not enough material that I could find. Please share your knowledge.
The answer is no.
We were running on an instance which had no Hardware virtualization support. Now we tested on a new virtualized system with Intel Virtualization Technology. The Application here is a 32 bit system and the new system was 64 bit OS - Ubuntu. This was run using gcc-multilib support for Ubuntu. There was not a huge performance improvement observed.
For my learning I am planning to create a 2 node Cloudera Hadoop cluster. I have a 32 bit Windows XP machine and now I have bought a 64 bit Windows 8 machine (as now all machines are found in 64 bit mostly).
So I have 2 options:
Create virtual cluster in the 64 bit machine (which is i5 processor and 8 GB RAM). But, I am not sure if it will hang (I am not trying to process millions of records. My motto is to simply process few files and check Hadoop functionality also dump some data from Oracle and play around).
I can create a physical Hadoop cluster between say the 64 bit and 32 bit machines. But my question is that, is it viable option (can I create Hadoop cluster between two machines: one 32 bit and another 64 bit)? If so, what is the process? I don't have much idea on networking.
I have also a basic question, what should be basic RAM and processor configuration for running a 2 node virtual cluster with simple operation like loading few data and checking the functionality?
It depends upon hadoop version you are using if version supports 32 bit then it wont work along with a 64 bit machine but if it supports 64 bit then it will run on that machine. Apart from that you should also check with your jdk version install. It might be possible that if both the machines have 32 bit jdk then version of hadoop supporting 32 bit will work irrespective of the machine.
I am not sure but it should totally depends upon jdk as it will be at top of the OS.
1. install 32 bit jdk on both the machines.
2. install older 32 bit hadoop version on both the machines.
I think this will work fine for you and
I have a vbscript, which connects to a .mdb file using 32 bit drivers and it works fine on a 32 bit system, but when i try to run the same on a 64 bit system( with 32 bit office),the connection doesnt work.
I cant install 64 bit drivers as the system has 32 bit office.
Is it possible to connect to .mdb file using 32 bit drivers on a 64 bit system?
For your scenario, just make sure that the process executing your script is running on 32 bit.
You could try to call your script from the x86 PowerShell prompt to test it on your x64 system.
I install Oracle 11gR2 32 bit client on my Win7 64 bit machine. its Oracle.DataAccess.dll's version is 2.111.7.0. When I run my code, I got this error message:
Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified.
What's the problem? Does it means, I cannot use this 32 bit on my Win7 64 bit machine, I have to install 64 bit version of it? Because 32 bit is our company policy to install on all my user's machine. It is hard to change it.
Thank you so much

If you run the application in 32 bit mode and link it against this specific version in the first place, it works and you can use the 32 bit version on a 64 bit system.
To force an application to run in 32 bit mode, you have several options (partially depending on whethere it's a stand-alone application or web application), which are outline in this article.
Just a simple question: Is there any way to run a program compiled under a 64 bit Windows environment (with mingw64) on a 32 bit machine? Any DLL or any compatibility layer which I can use?
If you are talking about a 32-bit processor, then no. But if you are running a 32-bit OS on 64-bit hardware, then you can do it with VMWare. A 64-bit guest can run on a 32-bit host, if the hardware supports it.
Bochs should do the trick, but you'd need another copy of Windows to run in the virtual machine. (Some editions of Windows include additional licenses for virtual machines, so you might be in luck.)
Performance would probably be very poor.
No you cannot do this. The other direction is possible through an emulator, e.g. on Windows it is called WOW64.
It is standard practise on platforms that still have large install base of the 32-bit versions of the OS to ship either just a 32-bit version, or both 32- and 64-bit versions.
I can recommend VirtualBox for this purpose, you can download the free version and it's easier to use than VMWare. However you will need a 64bit installation CDROM, and storage space for a full system install, and if you are installing Microsoft Windows they will expect you to pay for a license key.
Also your CPU needs to support both 64 bit mode in the hardware, and the vt-X/AMD-V features (most of them do). It's a bit slower, although mostly that seems to be the display that slows it down, not the internal program calculations. This is NOT an emulation, the CPU is really running native 64 bit, but VirtualBox fakes the hardware devices (display, disk, network, etc) so the result is not as nice as running normally. 3D graphics acceleration is available, but it has limitations.
An easier option is simply to hire an online Virtual Machine by searching for someone offering 64 bit versions of Windows Server (there are plenty). Usually they will offer connection over Remote Desktop, typically you can pay by the month. Upload your programs, run what you want, then delete it when you are finished and cancel the service. The service provider handles installation, licensing, hardware, etc.
hey that was a problem that gave me a headache for a while but i solved it. I had windows 10 32 bit but when i opened system in control panel it said that "32 bit architecture, 64 bit processor." lookup some websites and your hardware must have a few things which you can check in CPU-Z( lookup some webpages for this) its necessary. Then export your folders,documents, softwares in an external hard drive..now download the windows 10 64 bit iso file and boot it.ands viola! you got 64 bit architecture ( i also recommend upgrading ram atleast minimum 4 gb) or the other way is to install 64 bit guest in VMware ir another virtual machine software...gud luck
No, It is not possible...........
