HOW TO set NAV Service Startup Type via PowerShell

When you create a new Instance using the command New-NAVServerInstance it will set the Startup Type of the NAV Service as “Automatic” by default.

I haven’t found any NAV command to change it, so let us think about NAV Service as any other Windows Service.

In PowerShell there is a command Set-Service that allows to change an existing Service.

NAV Service names have the following format

MicrosoftDynamicsNavServer$<ServerInstance>

where <ServerInstance> is the name of the NAV Instance

So running the following command we can change the Startup Type to Automatic, Manual or Disabled.

Set-Service –Name "MicrosoftDynamicsNavServer`$DynamicsNAV100" –StartupType Manual

This example will set the NAV Service for the Server Instance DynamicsNAV100 to Manual.

Unfortunately -StartupType parameter does not have a value for Automatic (Delayed Start)

So it seams a bit tricky but just looking into the register I’ve noted that the other services that had Automatic (Delayed Start) as Startup Type have a REG_DWORD value called “DelayedAutoStart” with value 1 under HKLM\System\CurrentControlSet\Services\

So the idea is use the previous command to set the Startup Type to Automatic then add REG_DWORD via script

Set-Service –Name "MicrosoftDynamicsNavServer`$DynamicsNAV100" –StartupType Automatic
Set-ItemProperty -Path "Registry::HKLM\System\CurrentControlSet\Services\MicrosoftDynamicsNavServer`$DynamicsNAV100" -Name "DelayedAutostart" -Value 1 -Type DWORD

In reality we could setup everything from the registry

Set-ItemProperty -Path "Registry::HKLM\System\CurrentControlSet\Services\MicrosoftDynamicsNavServer`$DynamicsNAV100" -Name "Start" -Value 2 -Type DWORD
Set-ItemProperty -Path "Registry::HKLM\System\CurrentControlSet\Services\MicrosoftDynamicsNavServer`$DynamicsNAV100" -Name "DelayedAutostart" -Value 1 -Type DWORD

NOTE 1: Both scripts will work only if the current Startup Type is different of Automatic
NOTE 2: “DelayedAutostart” DWORD will have effect only if you setup the Service Type as Automatic.

HOW TO run SQL query for multiple companies in NAV database

In Micrososoft Dynamics NAV, tables with property DataPerCompany = No are stored in SQL in multiple tables having the company name as prefix, than $ and the name.

Example, the Customer table in Cronus Company:

CRONUS UK Ltd_$Customer

The following T-SQL Script retrieves the list of the companies, loop through them and use the Company Name as prefix (@pref) to run a query (@sql_ext).

DECLARE @pref nvarchar(30)
DECLARE @sql_ext nvarchar(max)

DECLARE company_cursor CURSOR FOR 
SELECT replace(Name,'.','_') FROM Company

OPEN company_cursor
FETCH NEXT FROM company_cursor INTO @pref 

WHILE @@FETCH_STATUS = 0
BEGIN

SELECT @sql_ext = N'SELECT * FROM [dbo].[' + @pref + '$Inquiry Note] WHERE DATALENGTH([Note]) < 4'

EXEC sp_executesql @sql_ext
FETCH NEXT FROM company_cursor INTO @pref 
END

CLOSE company_cursor  
DEALLOCATE company_cursor
