Hi Ashwin,
For Adapter if you want to shutdown, then you have to kill the services for that adapter using script.
But before doing this activity you have to changes the configuration of Adapter. In Adapter we have a option called "Auto Start" by defult it was "True" make it as a "False" then re-start the Adpater.
So it means when your Job Server restart your Adapter will not start automatically you have to start manually.
So Create a script to kill the services for Adapter.
Thanks,
Daya
