Not sure what is going on, but it definitely works, must be something
not right in what you are doing.
How are you starting the tcp server?

Hello,
I'm not sure what's wrong, I'm not able to connect to the same
database from two processes at the same time.
Both processes (running on the same machine but different JVMs) are
connecting via TCP server :
jdbc:h2:tcp://localhost/~/my_database;IGNORECASE=TRUE
I checked a number of forum postings and documentation, and I think
I'm doing everything as I'm supposed to...
First process connects fine, but the second process is getting this
error while trying to connect:
