I am profiling a java process which is running on 64 bit JVM on a linux box, I cant launch a GUI on that linux box.
When i connect from my 32 bit windows box i get error
JProfiler> ERROR: another application or a different
JProfiler> version of JProfiler tried to connect.
Is it that i need a 64 bit machine to connect to the remote 64 bit machine and get the profiling details?
You have to use the same version of JProfiler for the profiling agent (on the remote Linux box) and the JProfiler GUI (on your local Windows machine).
The "bitness" of the profiling agent does not matter.

I am using VMWare Workstation 14, with Windows Server 2016 installed on it. A few weeks ago in my server class, we had an in class lab to setup a Nano Server. I successfully got that up and running and installed Hyper-V and loaded it into it. Started up, and signed in. Then two days later at class again, the VM just freezes at the windows logo with circling white dots.
I have installed multiple VMs trying to get it up and running. Always the same result. I have the virtualization enable in BIOS on my laptop.
I have a VM snapshot I just took before installing Hyper-V, installed the role, rebooted, and again, stops at the windows logo with circling dots.
I don't know where to check if there is an issue, or if something is configured incorrectly. I am just looking for some help and ideas on what I should check. I do also have the virtualization stuff within VMWare enabled under the properties for the VM.
System details:
Asus GL502VMZ
Version 10.0.17134 Build 17134
Processor Intel(R) Core(TM) i7-7700HQ CPU # 2.80GHz, 2808 Mhz, 4 Core(s), 8 Logical Processor(s)
Installed Physical Memory (RAM) 16.0 GB
NVIDIA GeForce GTX 1060 3GB
Have you tried uninstalling the anti-virus? I was running into the same issue in my server class (Using VMware to run server 2016 which we where using to nest hyper-v)until a class mate said he didn't have the AV (we where looking for differences on why his worked and mind didn't). I removed my AV (was AVG) now the server no longer stalls at the boot screen.
Just my 2 cents that may help someone in the future. I had the same issue on an HP Proliant ML310e that worked fine for the full install until enabling the Hyper-V role, then it would hang at the Windows icon screen with the swirling dots. I was able to get past that by disabling Intel VT-d in the bios. Not a particularly good solution, but it allowed the system to boot successfully and run normally.
I'm currently trying to connect MongoDB to a Windows QT C++ application and am following the tutorial here. While there Windows installation instructions are presented, to avoid having to install Visual Studio or other tools, I'm wondering if I can follow the package-manager or Linux instructions on the inbuilt Linux/ Ubuntu subsystem of Windows 10 and build the libraries in my Linux environment, later somehow accessing them from my Windows development environment.
I don't fully understand how compilation/ byte-code works in the Linux subsystem on Windows, so I haven't been able to piece together an answer for this myself based on my understanding of the various systems involved. Any explanation or assistance would be appreciated.
You can run a Windows executable from a WSL console window or a Linux executable from Windows command line / power shell. And capture the output, pipe between applications etc. But the application must run entirely on one platform; you cannot mix a Windows executable with Linux libraries or vice-versa.
I don't know how you will connect to MongoDB but, if it has a socket interface like MySql, you could create a bash script on WSL which runs your QT application to access the database, wherever it is.
But if you're using QT as a GUI you're going to struggle. People have been able to get a Linux desktop running on WSL by installing an X server on the Windows host but you might find that more trouble than it's worth.
Is it possible to install opscenter on 32 bit linux machines (i am using beaglebone) running ubuntu 14.04 LTS? If not is it still possible to monitor a cassandra cluster which is running on 32 bit linux machines from a 64 bit machine? I see there is project done using raspberry pi here . I am not quite sure how they setup opscenter 5.0 to work with raspberry pi's.
Is it possible to install opscenter on 32 bit linux machines (i am using beaglebone) running ubuntu 14.04 LTS?
Yes, it is possible. Opscenterd supports both 32- and 64-bit distros, and agents run on JVM so they run pretty much anywhere.
If not is it still possible to monitor a cassandra cluster which is running on 32 bit linux machines from a 64 bit machine?
What makes you think it was not possible? Are there any articles/SO questions stating that? It should work just fine.
I am trying to run IEDriverServer.exe on 64bit windows system.
The following is the output on windows command prompt on my desktop.
D:>IEDriver.exe 000000013F19C740000000013F19C7885555',
000000013F19C7A0', 000000013F19C7B8', 000000013F19C7D8'
What does this error mean?
However i can run the same IEDriverServer on the other computer.
The following is the output on windows command prompt on my desktop. (I am using the same IEDriver.exe file copied from the other system.)
E:\Demo\swas\src\Configuration>IEDriver.exe Started
InternetExplorerDriver server (64-bit)
2.31.0.0 Listening on port 5555
There are two IE drivers one is for 32 bit browser and one is for 64 bit browser. The problem can be random also on some systems because of difference in windows updates.
Downloading proper version removes the problem.
I am tryin to install kali linux 1.0.9 on virtualbox for some testing purposes. (I am new with virtual machines). So i downloaded the 64-bit version of the os. i have got two problems:-
for some reason virtualbox does not show me a debian 64 bit version option in the settings(however it does show 32-bit option).
virtualbox doesnt allow me to change the no. of processors(default value is 1). i have got 8 cpus.
please help. my specs - intel i7 2670 memory- 6GB HDD-700 GB graphics - radeon 7670 HD
I have got windows 7 ultimate 64-Bit installed on the host
You need to enable 'Virtualization' option in your BIOS settings. The name of the settings may be different in different BIOS/motherboard brands. But you can easily identify it, in the BIOS.
I also had the same problem. I am in windows 8.1 and for my case, the problem was due to conflicts with Hyper-V who was activated in my system. I solved the problem by disabling Hyper-V.
Open windows features and Uncheck Hyper-V, click/tap on OK
