[Building Sakai] Fwd: availability setting on forums problem

[Bryan Holladay]

I haven't looked at the announcements code for a while, but if it uses the
SchedulerInvocationManager, then it will be connected to the same 10 min
interval.  It could have been a timing thing, i.e., announcement was
created in the future (future announcements only btw) and that time was
closer to the 10 min interval than your Forums time (i.e. intervals 10:00,
10:10, 10:20, 10:30..., and announcement set to go out at 10:09 while
forums set to open at 10:11).  In that case, announcements will only have
to wait 1 min while forums would have to wait 9 mins.  If you are seeing
anything going beyond the 10 min mark, then there is a bug, otherwise, it's
by design.  You don't want to overload the server checking too often.
 However, 10 mins seems high, you would probably be safe with 5 mins, which
you can set via the sakai.properties.

Thanks,
Bryan
