This article discusses the procedure that you can use to create a log file that can help troubleshoot failures that may occur when creating MDS database.
You can use the following procedure to enable the log file:
Open the MDSConfigTool.exe.config file located in C:\Program Files\Microsoft SQL Server\Master Data Services\Configuration using notepad.exe.
Uncomment the followin line in the file by removing the <!-- prefix characters and --> suffix characters on that line:
<add name="LogFileListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="MdsConfigManagerTrace.log" traceOutputOptions="DateTime" />
Make sure switchValue is set to All.
<source name="MDS" switchType="System.Diagnostics.SourceSwitch" switchValue="All">
Try again to create the database. Afterwards, open the MdsConfigManagerTrace.log that is saved to C:\Program Files\Microsoft SQL Server\Master Data Services\Configuration and review the same for additional information regarding the failure.
