====
In the syntax "ddbstore_driver_url=jdbc:oracle:thin:@127.0.0.1:1521/orcl", it can be seen that you are using the same database (orcl) and the same username/password ("test") for all three stores [$formula($sys.nonfailsafe)] [$formula($sys.meta)] and [$formula($sys.failsafe)] - this is not allowed.
