Increase database connection pool size?

Currently we're using Derby in embedded mode, and it is configured to only have a single connection in the db connection pool:

[INFO] access.QueryLogger Created connection pool: jdbc:derby:database/componentSearchDB
Driver class: org.apache.derby.jdbc.EmbeddedDriver
Min. connections in the pool: 1
Max. connections in the pool: 1

I assume that we'll want that number to be a bit higher.
