Modifying Adapter Connection Settings at runtime


Is it possible to control the connection parameters of an adapter connection at runtime. Lets say, I create a JDBC adapter connection JDBCConn1 on a database OracleDatabase1 and create all my adapter services using this connection. During runtime, if I need to connect to OracleDatabase2 and I dont have a connection, is it possible to modify the connection parameters of JDBCConn1 and point it to OracleDatabase2 and use my services as is. The database schemas on OracleDatabase1 and 2 are the same.

Any help is greatly appreciated.
