I would be interested in your experiences with 5 hours. We went
for 40 minutes in order to give the server a chance to free RAM.
Since Seaside by default doesn't clean up sessions when they
expire, but only when new ones are requested, I'd be worried about
memory usage with such long session intervals...<br>
<br></div></div></blockquote><div><br></div><div>Hi Jooachim,</div><div><br></div><div>Indeed, there is usually the tradeoff between larger timeouts and the memory consumption. In my particular case, the UI of the app allows having multiple tabs, multiple workspaces, and there are even settings/preferences and other things that are scoped to session level. In addition, some of the components are quite complex for the user to get there. That's why they really appreciate long during sessions. And finally, because there are not that many users. </div><div><br></div><div>Now, to answer your question, I think the answer is that my RAM does not gets affected much because we are running in GemStone. In GemStone, the Seaside sessions are not transient (temp) but *persistent* objects. In this regard, the main memory to consider in GemStone is the Share Page Cache (the cache of persistent objects on memory). If I got things right, having long sessions does not affect much. Worst scenario if a have an unused session is that if another new sessions comes in and I don't have much free space in the Share Page Cache, then the old "unused" session (at the end this is like any persistent object) will be moved back to disk to make room. In other words, I think in the worst scenario this would cause some trashing (moving objects between SPC an disk). </div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div bgcolor="#FFFFFF" text="#000000"><div class="m_6729047939478226259moz-cite-prefix">
Another question: what do maximumRelativeAge and
maximumAbsoluteAge acrually do? Is this some way of tweaking the
session cleanup policy?<br>

This "maximum age" session parameters are correctly showing
in seaside config web app, but every seaside session is
still 30 minutes.<br>
<br>
What is proper way to configure session timeouts (age),
dynamically, via code?<br>
<br>
Thanks, pf<br>
