[Using Sakai] [sakai-kaltura] How do you approach Sakai timeouts when viewing long video content

Tue Nov 29 09:05:00 PST 2011

At Yale, we have simply put a Javascript at the uploadMadia.jsp page as following

-Add the line below inside your jsp page
<img id="keepAliveIMG" width="1" height="1" src="images/video.png?" />

--Appending the following javascript in your page
<script>
function keepMeAlive(imgName) {
        myImg = document.getElementById(imgName);
        if (myImg)
            myImg.src = myImg.src.replace(/\?.*$/, '?' + Math.random());
     }

window.setInterval("keepMeAlive('keepAliveIMG')", 120000);//2-minutes
</script>

Basically, it will pull the image every 2 minutes to keep session alive.

You can do this on any page, which it might be running out the session.

Thanks,
Peter

You can refresh the users session by periodically polling
<servername>/direct/session/current

Hitting this url will update the session time. If it's not on the same domain, you might not be able to get at the values but that wouldn't be important.

You'd probably have to add some javascript to Kaltura or if you're using the Sakai kaltura tool to do it. This sounds like what David did?

A long timeout doesn't seem like that big of a deal anymore though either. All of the big platforms (GmailFacebook/Twitter/etc) seems to have nearly unlimited length sessions. I've never seen a logout message on any of those sites. I think students would be risking a lot more (socially) if they left a public computer logged in nowadays while remaining logged into those services. ;)

Thanks so much for your replies.

Jama, would you be able to tell me what your Sakai time-out is set to?

David, that Media Gallery modification sounds like it might be what we're looking for. Would it be something you're able to share with us?

Mathieu, I agree. I don't know if a separate window is the solution, but we can explore it.

Thanks again!

We haven't had this problem reported at Yale, either, but we modified our Media Gallery (SKE) tool so that it simulates activity on the page every 10-15 seconds.  We did this because faculty were reporting their Sakai session would time out while uploading a very large media file to Kaltura via Media Gallery.  I'm guessing that the same simulated activity would prevent students' sessions from timing out as long as their browser remains on the tool page.

Hi Rebecca,
We haven't had this issue reported at UVA.  I'm assuming our session timeout must be long enough to accommodate.

Hi all,

We're using Kaltura for video reserves in Sakai this spring. Some of the films are 2.5 to 3.5 hrs long, but our inactive timeout for Sakai is set to 2 hrs. When students are viewing a film full screen, they forget they're in Sakai, and it times out on them in the background. Whether you're using Kaltura or viewing other long-form videos, aside from extending the timeout, what other options are you using for working around this kind of problem?

Thanks!
