How to run SuperClassic on Linux

Firebird 2.5 brings a new architecture called SuperClassic. The official FB 2.5 Linux packages brings SuperClassic and Classic in the same package, and when you install it, Classic will be activated by default.

To be able to change to SuperClassic, you need to run the script changeMultiConnectMode.sh that is installed with FB 2.5.

You will be prompted with: “Which option would you like to choose: multi-(process|thread) [process]”

Answering thread will activate SuperClassic, while process will activate Classic mode.
