Failed to execute DB

[trend]

Hi, I received a message "Failed to execute DB job 'executionUpdateJob':
ObjectSpace:Entity Object not being Tracked - NinjaTrader.Cbi.Execution:
ExcID...." for several ExcID repeated over a few minutes (Log Category: Default-GreenColor).
After these few minutes the problem did not appear again (about 8 hours since). Any clues?

Thanks,

Hmm .. sorry I would not know. I needed a reproducible scenario to analyze.

[trend]

Well, I have a script up and running on a dozen of markets for a couple of days now, along with one chart and the market analyzer.
(The messages in the log reappeared. Don't seem to crash the application.)

Similar setup in another machine (with no charts and market analyzer up) and for more days did not show any problems.
I've noticed in an old post (6.5--) to rename the database to old and restart. Would that apply to NT7 as well?

If left as is would the application crash at some point?

thanks,

[NinjaTrader_Dierk]

- The application should not crash. It's just than an execution could not be saved to the DB.
- renaming the DB would not address the cause of trouble

[trend]

To doublecheck, would this DB failure affect in regards
of the ongoing signal generation by the script?
Thanks,

[NinjaTrader_Dierk]

No, it would not impact the strategy itself nor signal generation in particular.

I took a look on the trace files. There are Warning messages
of the following:
Db.Globals.StrategyUpdateJob2: WARNING: Execution='' Instrument='EURJPY' Account='Sim101' name='Virtual Entry Execution' Exchange=Ace .....

Following this Warning there are many more WARNINGS refering to all signals taken on EURJPY since NT was loaded.

EURJPY is assigned to Default (not Ace). It seems that after long
operation the Instrument's Exchange reverts to Ace (1st one in the list)
Any clues?

It might help if you posted the complete message. Thanks

Thanks. The Ace issue does not seem to be related. However, I put in some code for NT7B5 which "should" prevent this happening.

[trend]

Actually, I see the "..Exchange=Ace.." entries in trace files from 6.5 as well,
except that in 6.5 I don't see the "Failed to execute DB job ...Entity Object
not being Tracked..."
The only change I made in the code from 6.5 to 7 was to substitute EnterLong(...) with
SubmitOrder(...)

Hi,
I still receive occasionally the DB related messages
"Failed to track DB object.....".

Each of this messages opens a new window.
Also, if the connection goes down each of the strategies
pops up a window. (You might end up with dozens of these
windows that you have to click OK to get rid of).
Is there a way to suppress all these messages into a single window?
which could be up at al times or whenever you click it?

Thanks,

[NinjaTrader_Ray]

There is no way to surpress and would be great if you reported back once we release beta 5 since we put in some code that we hope should prevent this from happening.

[tradejockey]

I get this message literally everytime trade triggers (in replay). got it like a dozen times already in past half hour of running replay... running beta5

[NinjaTrader_Dierk]

Which message are you referring to?
