What happens when you try it?
What value does it have when Broker first starts up? How does it get that value? |

Of course they won't be. No variable in any language I'm aware of survives the closing or crashing of the application.

To be more correct, the shared variable is indeed *available* after the Broker or EG restarts.
The *value* that it holds will almost certainly be different than the value it held before the restart, however. |

What you are looking for is a shared variable read from a DB and each update needs to get written to the DB.
In case of a crash the latest value would be read from the DB to initialize the shared variable...
Have fun changing your design...
