Start/Stop SAP B1H Service Layer

Hi All,

I’d like to share some stuff that took me a couple of hours to solve even though it was as simple as a 5-minute task.

The situation was that I was in the middle of a development that included interaction with the Service Layer and for external reasons I needed to restart the SAP HANA server. After that, my developments didn’t work. I found out that the Service Layer was not started since nothing was coming back from https://<servername>:50000/b1s/v1. I spent some time to realise the path to the service through which the Service Layer can be started or stopped and that’s what I want to share with you today.

To start the Service Layer simply run the following line in the SUSE console:


/etc/init.d/b1s start

To stop it just change start for stop.

That’s all. So, remember: If the Service Layer is installed but does not work, chances are that it’s not started.

Hope this helps.

      Hi

      I have a problem with those commands. Get the following error:

      startError.png

      And by placing the URL https://<servername>:50000/b1s/v1 do not work.

      Get the error server unavailable.

      Thanks

      Thank you Alejandro Fonseca,

      It solved my problem...

      Complementing your solution, to avoid this service to stop every time the Hana machine restart, you can turn on the automatic start of this service executing the following command on linux:

      chkconfig b1s on
