Hi,

I am trying to connect to a MySQL DB but I get this error message

Cannot create PoolableConnectionFactory (Unknown database 'test')

I have tried uninstalling both ignition and MySQL and installing them again and updating the JDBC

I have previously connected the same version of MySQL with the same version of ignition

If any one can help I would appreciate it

Does the db have a schema called _ **test** _? It's saying there is not.

I manually created a new schema named "test" and it worked well

Thank you
