Unable to connect to DB after upgrading to NinjaTrader 8.0.27.0

Hello 2commakid,

Can you please right click in the chart and select 'Reload All Historical Data'. Check if the missing historical data is loaded. If not, please perform a restart of the NinjaTrader platform and check again. If not loaded initially, please right click in the chart once more and select 'Reload All Historical Data'.

If the issue remains, please tell me for what instrument and what period (+ time zone) you have historical data missing.

Hello makeuptime,

Did you try the instructions below? This resolved the issue for other clients that run NinjaTrader on a Mac with Parallels.

When installing NinjaTrader on a Mac using Parallels, you will need to ensure that the following steps have been taken prior to the installation of NinjaTrader.

• Start Parallels and select your virtual machine
• Press the "Configure" button on the top
• Under "Options", select "Sharing"
• Uncheck "Share Mac" under "Share Mac User Folders with Windows"
• Press "OK" and start the virtual machine

Could it be "Share Mac" setting is checked? If so, please uninstall NinjaTrader as per the instructions below, then uncheck "Share Mac" and subsequently reinstall NinjaTrader.

• Make sure NinjaTrader is shut down.
• Uninstall NinjaTrader 8 via Windows start menu-->Settings-->Apps.
• Uncheck "Share Mac" in Parallels
• Download and install NinjaTrader 8.0.27.0 from the link below.
• https://ninjatrader.com/PlatformDirect

Check if you are now able to start NinjaTrader successful. If the issue remains, please send me your log and trace files.

If the issue remains, please send me the log and trace files. The Control Center refers to the NinjaTrader Control Center (see attached screenshot).

Good afternoon. I am experiencing this issue as well. Prior to today I have use Ninja Trader with trade copier without issue.

The issue started this morning when trade copier was not functioning properly. (I have 10 accounts linked through trade copier and it was only showing trades on 5 even though all were configured to trade per usual.)

After some basic troubleshooting I decided to uninstall/reinstall Ninja Trader. I have now done this numerous times. Here is my setup:

NinjaTrader (latest version downloaded today)

Windows 11(OS build 22621.963)

Running on Parallels Desktop (Version 18.1.1)

Running on 2020 MacBook Pro with macOS Ventura 13.0.1

After the reinstall I receive the error message "Error: Unable to connect to DB: unable to open database file". Then the app closes out after pressing OK.

I have attempted:

Uninstall reinstall multiple times.
Rename folder in documents after uninstall.
Verified parallel settings.

Please help!

Update - I resolved the issue by also unchecking the "Mirror Mac..." option in the parallels settings referenced above then uninstall reinstall again. I'm hoping a future Ninja Trader update will allow both features to work.

Actually I found what caused my problem, same as others here with W11 on Parallels
Instead of just not ticking the "Share custom Mac folder with Windows" I also chose to go under "Customize" and untick "Documents".
After that, reinstall Ninjatrader and now works perfectly !
Hope it will help others

Hi

The same issue, just installed Parallels, Win 11 and NinjaTrader the latest version.
The option with shared options is unchecked (was 'unchecked' before ninjatrader installation)

But can't even login, always the same error that it 'could not connect to db'

MacBook with M1 Pro, 12.01 (Monterey), Parallels 18.x, NinjaTrader 8.1.1.3

Is there any way to somehow manipulate with sql files, or maybe something else is required (sqlite, etc). I don't see any useful logs

Thanks

Hello wendigooooor,

If you uncheck "Documents" under "Customize" as Oli_Vier reported in post 20 and then reinstall NinjaTrader, does the issue persist?

Wow, I don't know how I missed that message. It works, thanks.
Sorry for the inattention

This is not fixing the issue for me. How do I send you log and trace files?
