WebMap 2016: Unable to create library database objects. Standard metadata tables may be missing

Dear all,

 

We encountered an issue with WebMap 2016 (16.00.0100.0009) in conjunction with WMS-Service sources (created with WebMap 2016) having dynamic labels.

On the testserver everything works well. However, on the productive system, we encounter quite a bunge of event-viewer entries saying "unable to create library database objects. Standard metadata tables may be missing".

 

The above mentioned event-viewer entries always refer to a WebMap log files. The refered log-files show two different patterns:

1) Pattern 1: Logfile not containing any error --> {C3BB2BD7-B385-4584-88DC-41EF921605D2}.GWMLog

2) Pattern 2: Logfile with a pretty mysterious entry: "GMWS: Error - GetLegendEntry: GetLegendEntries: The Method '~' for the Object '~' failed --> {A07C060D-8DAB-4AD0-932F-D1DB8B555F9C}.GWMLog (--> however, the error message is originally logged in German: "Die Methode '~' für das Objekt '~' ist fehlgeschlagen")

 

Has anybody an idea what might cause this error message? And, what might be the reasons for causing the event-viewer error message "unable to create library database objects. Standard metadata tables may be missing"

 

Any hints are highly appreciated.

Thanks and Regards,

Dominik

Re: WebMap 2016: Unable to create library database objects. Standard metadata tables may be missing

Both the log files indicate an error condition, dal. Even though one of them is not entirely obvious:

{A07C060D-8DAB-4AD0-932F-D1DB8B555F9C}.GWMLog
2017-04-12 13:55:28 (1.259404) - Connected 80040bc6
2017-04-12 13:55:28 (1.259432) - End of ActivateOrConnectLibrary 80040bc6
2017-04-12 13:55:28 (1.261531) - Exiting AddLibraryConnection - 80040bc6

{C3BB2BD7-B385-4584-88DC-41EF921605D2}.GWMLog
2017-04-12 13:58:42 (0.937650) - Connected 80040bc6
2017-04-12 13:58:42 (0.937675) - End of ActivateOrConnectLibrary 80040bc6
2017-04-12 13:58:42 (0.938836) - Exiting AddLibraryConnection - 80040bc6


Lots and lots of detailed GWMLog entries don't indicate an error connection directly, but instead append a HRESULT to the log line.

 

According to http://community.hexagongeospatial.com/t5/WebGIS-Q-A/COMException-error-from-HRESULT-while-working-w... this HRESULT means GF_HE_TooManyOpenTables which might be related to the fact that you are using a myriad of Access Warehouse libraries and saturated the global connection limit of the JET OLEDB provider, see answer to this stack overflow question: http://stackoverflow.com/questions/5367668/how-many-users-can-open-a-connection-to-microsoft-access

Re: WebMap 2016: Unable to create library database objects. Standard metadata tables may be missing

Thanks for the hint. It is very likely that we're confronted with the open-tables-limitation of Access in this particular situation. I'll discuss further steps with our customer.
