Mango not starting back up after restart within Mango

[hayden_AUS]

Hi,

I have recently setup my demo site on a W7 PC, that is running NoSQL DB, V3.5.6

I setup the Windows service using YAJSW as described in the docs.

When I restart Windows, Mango starts up automatically as a service.
When I restart from within Mango, it will not restart.

Further to this, it appears that Mango is starting a browser on the host machine on
startup, but it is not visible in Windows. I can see Firefox in windows Tasklist, but not even
in Taskmanager.

Would this be causing the instance not to restart?
Is there a way to stop Mango from starting a browser?

Hi Hayden,

This is a known issue with the Windows service. The Mango/bin/ scripts handle the restart through Mango, but because ma-start.bat is bypassed in the Windows service its mechanisms for restarting are not in play.

To the opening the browser, that's in the env.properties and can be set like,
web.openBrowserOnStartup=false

Hi Phil,

Is there a workaround for the Windows service issue?

At the moment I can remote in after doing an upgrade, and manually start the service within
Windows.

Not currently. It's one of the reasons we encourage people to use Linux for their deployments.

The issue is that the restart mechanism leverages the ma-start.bat script, which is completely bypassed by the service. I can't personally say I know very much about Windows services, but it would seem to me had the service been directed at invoking the batch script instead of the main application this issue wouldn't exist.

For instance, you can place a shortcut to the ma-start.bat file in the startup folder, create an event handler to create the Mango/RESTART file on the Mango startup event, and voila, it behaves mostly like a service and then restarting / upgrading should work.

Something like,

var restartFile = new java.io.File("C:\\Mango\\RESTART");
if( ! restartFile.exists() )
  file.createNewFile();
return UNCHANGED;

OK thanks Phil, will do some experimenting.
