Are you sure you are in the correct part of IS?
JDBC Pools section (below settings in IS Admin) is for configuring the database the IS is using itself for it’s storage and logging. Imho this should not be using different DB’S for different pools (although different schemas may make sense)
JDBC Adapter is for connecting to databases (mainly of applications) for using those in integrations. Those are configured using JDBC Adapter in the Adapter section. It is no problem to configure multiple databases of different type here.
