Maintenance Mode Exception

Batch Service Exception (Maintenance Mode) D365FO



Recently, My office colleague faced an issue while starting  Microsoft D365 windows batch services in Update 15. after 10 seconds of processing it's getting failed 



When we check in Event Viewer with below Path

Application and services Logs > Microsoft > Dynamics > AX-BatchService > Operations



Batch service throwing below Error 


After spending some hours on the internet root cause was found. this issue occurs When D365FO is On Maintenance Mode.

There are two ways to fix this issue...

The proper way; Use the Microsoft.Dynamics.AX.Deployment.Setup.exe command; 

Run this from the command line:

C:\AOSService\PackagesLocalDirectory\Bin\Microsoft.Dynamics.AX.Deployment.Setup.exe –metadatadir C:\AOSService\PackagesLocalDirectory –bindir C:\AOSService\PackagesLocalDirectory –sqlserver . –sqldatabase axdb –sqluser AOSUser –sqlpwd AOSWebSite@123 –setupmode maintenancemode –isinmaintenancemode false 


The Hack way; Use the Microsoft SQL Server Management Studio, and edit the following record in the table dbo.SQLSystemvariables ; CONFIGURATIONMODE

Update SQLSystemvariables set Value=0 where parm='CONFIGURATIONMODE'

BYOD (Bring your own database) D365FO




What is BYOD?

The BYOD feature was released in Microsoft Dynamics 365 with platform update 2 (August 2016)
BYOD feature lets administrators configure their own database, and then export one or more data entities that are available in Finance and Operations into it.
The BYOD feature allows you to push data into a database that you manage on Azure or on-premises.
This is done with the use of data entities. This means you can use existing entities or build your own entities to structure the data how you need for your external database. As per MSFT, Currently, more than 1700 Data entities are available.


Objective 

You have data in D365 running in the cloud but you still have other applications that you run on-premise or somewhere else. 

So you need to get data from D365 into another environment so other applications can use the data. 

The most common use of BYOD is for data analysis and long-running reporting (Long-running reports are the pain point of AX)


Prerequisite


First Create a database on Azure SQL or on-premise SQL (You need static IP for connection)

How to create a Database on Azure.

Fill out the below fields.



Click on a server to configure server for you newly created database a pop will appear to fill the required information 



Once the database is created on SQL or AZURE Then log in to D365 to configure the data source of the Newly created database. for Azure database detail please follow this link
