From a recent posting:

When a first db transaction is made, 2 connections to Oracle are created. Here is the why: When the first transaction is commited, EOF create a connection (the defaultEditingContext associated to a EOObjectStoreCoordinator) and analyze the eomodel used to commit changes. IF the emodel connection dictionary does'nt contains the key "jdbc2Info" - value NSMutableDictionary ( or if you overwrites the connection dictionary), EOF try to retrieve this infomation and create this dictionary. To construct this metada , it creates a new Connection but it's not closed! So the solution, is to ensure that this dictionary jdbc2Info is in your EOModel dictionary connection.

It looks like my WO app is creating two database connections every time it means to create one:

[2005-03-11 13:56:53 EST] <main> Using JDBCPlugIn 'com.webobjects.jdbcadaptor.OraclePlugIn' for JDBCAdaptor@6712442 [2005-03-11 13:56:53 EST] <main> connecting with dictionary:...

This is with the latest WO, the latest Mac OSX, and the recommended jdbc client (9.2.0.1). Has anyone seen this kind of behavior before? Thanks.
