I switched now from Windows to Linux Mate 16.04 (not plain Ubuntu because of its GUI).
The installation of Gemstone/S was not working, but one can change the installation code to make 16.04 known to the system and then it worked …
I installed Jade and VirtualBox with Windows 7 to get a nice GUI to develop under Gemstone/S.
I switch my working place quite often and therefore I had to change the settings of Jade also very often and when I was in the train it was not possible to work at all.
To get rid of all these problems I had a closer look to configure VirtualBox to solve these problems:
* Via the global VirtualBox/Settings one can add a host-only network. This results into a network adapter named like “vboxnet0” on your native running Linux machine. Due to this my Linux has also the IP address 192.168.56.1 (and within that network also a running DHCP server)
* In the Windows (Jade) virtual machine do configure a “Host-only Adapter” and connect it to the “vboxnet0” network configured above. Now this Windows machine gets a IP number in the 192.168.56.0 network – always.
Now the the guest and server system shares always a network 192.168.56.0 -regarding of your “outer” IP configuration.
The Windows system now has NO connection to the outer world – perhaps you might need to add an additional network adapter to make this work (e.g. NAT or bridge).
Communication between Gemstone/S and Jade now should be configured to run via the 192.168.56.0 network.
Now one has to solve the problem, that the NetLDI protocol uses a random port number and then everything is ok.
