NT7 cannot run in virtual machine with networked Documents folder?

[dolomite]

I've got a VirtualBox virtual machine running Windows 7. The host operating system is Ubuntu. The guest Windows 7 operating system's Documents folder has been moved to a 'network share' that sits on the host ext4 filesystem.

I installed NT7 to the guest, but get an error when trying to launch and connect to Kinetick:

Is there a known limitation where NT7 cannot run when the Documents folder sits on a network share or on a non-NTFS filesystem?

Of course I wouldn't be terribly surprised that this configuration will not work as NT was probably not designed with the idea that the data files might be stored on non-NTFS filesystems.

Hello,

Thank you for the question.

There is a known limitation surrounding network folders used in windows and the SQL framework NinjaTrader uses. This being said, it is not possible to install NinjaTraders user folder to a networked or shared folder.

You would need to revert the documents folder to a local folder in windows and then likely re install the platform to ensure all files and paths are correct.

This would be the same case if you were using any virtual machine, MAC computer using parallels or even just a normal windows install using a networked folder.

I look forward to being of further assistance.

Edit: nevermind. I read "not impossible" when you actually wrote "not possible".

Hello,

You would only be able to complete the first two steps, the network folder can not be involved if you want to use NinjaTrader.

The steps would be:

1. remove network folder configuration.
2. Ensure Documents folder is a local folder in windows
3. Re install NinjaTrader.

There is no point where you can share the documents folder to the host OS and also have NinjaTrader work. You are free to share any other folders you would like aside from the Documents folder as it contains the NinjaTrader folder which can not be shared. .

I look forward to being of further assistance.

Yep, sorry, I read "not impossible" where you actually wrote "not possible".

Unfortunately that is not true. One can share the local "Documents" folder: one cannot locate the "Documents folder" on a shared drive from another computer if NinjaTrader is to run. Very different things.

Interesting, I did not know this.

Where is this limitation documented?

Got links?

Try it. It just doesn't work. Errors abound.

I've managed with Koganams previous posts of moving the entire My Documents folder to my Intel 750 Raid 0 on the same machine.

Don't want to try it.
Too much work right now.

[Edit: I just tried the command "mklink /D C:\Temp\Downloads S:\Downloads" to create a symbolic lnk to my networked Downloads folder. The command worked fine, no errors, and C:\Temp\Downloads works as expected. So I'm pretty sure I could make the "NinjaTrader 7" folder a symlink to somewhere on my networked S: drive, too. Thus I'm curious what the known issues are with doing that. Win7 64bit Ultimate.]

NT Supports says it is known, so first I'm looking to catch-up with what is known.

I've managed with Koganams previous posts of moving the entire My Documents folder to my Intel 750 Raid 0 on the same machine.

I made a junction so that all Market Replay data in folder db/data actually points to "D:\NinjaTrader\Downloads\Market Replay" -- but D: is a second physical disk in my machine. Works great.

But what caught my eye about this post was:
A couple of years ago, at the time I created that junction, I almost used my S: drive, which is mapped to my Synology NAS device. I'm curious as to the problems networked drives cause with SQL CE. Apparently these limitations are well known, so I'd like to know what they are.

[Edit-2: I would not expect problems if I had created that junction to my networked S: drive. Why? Because Market Replay data is treated as read-only by NinjaTrader. But if "db/NinjaTrader.sdf" resides on a network share, that, I presume, causes known problems? Ok, I say to myself, that's possible, but where is that known at?]

Thanks.

But that thread does not address networked drives.

Nor does it discuss use of the MKLINK command, which would be my preferred way of doing this.

[Edit: Actually, that thread starts to close down after Lorne mentions Symlink Creator (which is just a wrapper for the mklink command), so I stand corrected, mklink is discussed, sort of, in a high level way]

The guest Windows 7 operating system's Documents folder has been moved to a 'network share' that sits on the host ext4 filesystem.

How did you do this?
What commands did you use to move it?

Not that I have an answer, I'm just curious what you did that you later found didn't work.

I only mentioned the SymLink in passing, Symlinking a folder is not my preferred solution: I prefer to mount an entire partition into the folder and use that as my NT data folder. Yes, it is not networking, but the issue with SQL and network drives (as opposed to UNC paths) is pretty much documented by Microsoft themselves.

VirtualBox has something called "Shared Folders", set up at the high level of the VM itself, sharing folders on the host to the VM.
