Hello Martin, Have you confirmed the timings of shared vs. dedicated connection thru sqlplus session (not through application server OR webserver). Does sqlplus query execution timings still shows 1:30 minute and 1 hr respectively ? I understand that tracing could be done, however, before you embark upon that exercise, a basic test via sqlplus would surely rule out middle tier (application server/web server) being the contributing factor. -Rajeev On Tue, Apr 22, 2008 at 11:23 AM, Martin Klier <usn@xxxxxxxxx> wrote: > Dear list, > > Is there a difference in executing a query in dedicated vs. shared > server connection? > > The query plans are the same, but in shared server the query runs 1:30 > min, and in dedicated mode over an hour.
