Manual Start and Stop order of Qlik Sense services

[Sonja_Bauernfeind]

Manually restart Qlik Sense services in right order is important because the Qlik Sense Repository Service is dependent on the Qlik Sense Repository Database (QRD) and the rest of the services are dependent on the Qlik Sense Repository Service.

Please review the Qlik Sense Online help for the relevant Sense version to find the Service Dependencies for your specific version. 

In a Multi-node environment, start the central node first and stop the rim nodes first.

Correct Start Order:

Central node

1. Qlik Sense Repository Database (may also be called postgresql-x64-12)
2. (if installed) Qlik Sense Logging Service 
3. Qlik Sense Service Dispatcher
4. Qlik Sense Repository Service 
   Note: Delay for up to five seconds before starting the Qlik Sense Repository Service to allow the Dispatcher time to start its microservices. 
5. Qlik Sense Proxy Service, Qlik Sense Engine Service, Qlik Sense Scheduler Service, Qlik Sense Printing Service

Rim node

We are unable to provide a comprehensive start or stop order as rim nodes can have a number of different combinations of services installed. Please skip any services you do not have installed.

1. (if installed) Qlik Sense Logging Service 
2. Qlik Sense Service Dispatcher
3. Qlik Sense Repository Service 
   Note: Delay for up to five seconds before starting the Qlik Sense Repository Service to allow the Dispatcher time to start its microservices. 
4. Qlik Sense Proxy Service, Qlik Sense Engine Service, Qlik Sense Scheduler Service, Qlik Sense Printing Service

Correct Stop Order:

Central node

1. Qlik Sense Repository Database (QRD)
   This will first terminate all services with a dependency to the QRD (see Service dependencies on the Qlik Sense Online Help)
2. (if installed and not stopped already by step 1.) Qlik Sense Logging Service (If feature was enabled during installation)
3. Qlik Sense Service Dispatcher (QSD)

Rim node

We are unable to provide a comprehensive start or stop order as rim nodes can have a number of different combinations of services installed. Please skip any services you do not have installed.

1. Qlik Sense Proxy Service, Qlik Sense Engine Service, Qlik Sense Scheduler Service, Qlik Sense Printing Service
2. (if installed) Qlik Sense Logging Service 
3. Qlik Sense Repository Service
4. Qlik Sense Service Dispatcher (QSD)

Sample PS Script below for stopping and starting the Qlik Sense services:

Get-Service "Qlik*" | Where-Object {($_.Name -like "QlikSense*" -and $_.Name -notlike "QlikSenseRepositoryDatabase") -or ($_.Name -eq "QlikLoggingService")} | Stop-Service -Force 
Start-Service -Name "Qlik Sense Service Dispatcher" 
Start-Service -Name "QlikSenseServiceDispatcher" 
Start-Service "Qlik*"

 

Optional monitoring of start process:

Open the following location: C:\ProgramData\Qlik\Sense\Log\Repository\Trace
Monitor the folder after starting the Qlik Sense Repository Service (QRS). Files with appended time/date will disappear.

Question about the dependency and proper stopping order of Qlik Sense Service Dispatcher.

I noticed that when starting the services, Qlik Sense Service Dispatcher is listed as third in the list of services to start.

I would think that when stopping services, it would also be third from last to be stopped, but that's not the case. Qlik Sense Service Dispatcher is listed as the last service that should be stopped.

That implies, but I can't find anywhere that would confirm that Service Dispatcher is not dependent on Repository Database service.

@Sonja_Bauernfeind do you know if Qlik Sense Service Dispatcher is, in fact, not dependent on Qlik Sense Repository Database service?
