We run SunRay over Solaris 10 11/06 s10x_u3wos_10 X86 on SunFire X4100 servers with 2 processors and 4GB RAM, we have around 800 client and 12 servers, but we have some problems because the wasted resources with unused clients
What kind of problems? Have you tested how much of a specific resource is used up by idle client sessions? Do you have data that indicates you could save on something (presumably hardware) by getting rid of idle sessions and still be able to
I do note that 4GB RAM per server is very little for a Sun Ray server, especially, considering that you want to serve ~70 clients per server (and even more on outages).
We search for someway to disconnect the idle sessions (we have a very lazy users, even to power off the clients after finish work) to save some server resources, I found the "xautolock", I still facing problems with compiling it but this is not my question My question is "If I disconnect the client session from the server, the client will reconnect automatically, don't it? an reallocate some of server resources for itself again, which mean I save nothing !!!" is this conclusion is right ? or there is some thing a don't know and this plan will work will
It really depends on the kind of session you have whether killing one will save resources. In most cases it will save resources used not by the session framework, but by the actual applications. If the client remains connected with the same token (i.e. either without a smartcard or leaving a smartcard inserted), it will indeed reconnect, but only show the login greeter, which ought to be much cheaper than a full logged-in session..
OTOH if you use kiosk mode, then killing sessions will save very little, if the client remains connected with the same token, as the kiosk environment restarts
And is there any better way to save the resources from being wasted by idle session?
One possible way is to disable access without smartcards and require users to take their cards with them. Here the client will still immediately reconnect after a session ended, but the resulting session which just shows a 'insert card' icon should be rather cheap on resources.
