For a long time, we've recommended using separate Database handles in high-concurrency environments. The reason was that there was a hot spot involving maintenance of the list of Cursors used by the Database so that we could flag and close open Cursors at Database.close() time. We finally decided that maintaining this relationship was not worth the overhead and reduction in concurrency. So in JE 4.0 we will remove it. The results will be that sharing Database handles across threads will not incur a performance penalty. But we will also not automatically close Cursors at Database.close() time. The change log entries for this change (when it's available) will refer to [#15413] and [#16346]. Unfortunately, I can't say when this release will be available because of Oracle policies. But I can say that one of the main areas we're emphasizing is performance.
