Where there? MMC is a frontend to start and stop the instance. It's a bit more information required what exactly is not started to be able to help...

Hello Marcus,

So your ABAP system doesn't find the Java instance by name, right?

Yes indeed.

So did you change the hosts file on the SERVER? If this is a windows instance you must make sure to add an empty line in the hosts file if it'S the last line.

After that you need to reset the hostname buffers in the ABAP system to re-read it (using SM51) - or restart the ABAP instance.
