Solaris 10, Sun Ray Server Software

Hi,
I installed Solaris 10 on my x86 machine and managed to get it (eventually!) configured with a static IP etc.
I then began the install of Sun Ray Server Software and the first part went well. I then performed a reboot as requested using
sync;sync;init 6As this occured i spotted an error saying gzip problem due to not enough space when doing something with the boot_archive. I have since not been able to reboot my machine as I get Error 28: Selected Item cannot fit into memory etc. I found an article on the forums saying log in using the cd to a single user shell, rename the boot_archive to boot_archive.disabled and reboot. This has not had any affect. When rebooting the same error about gzip and space occured and then the error 28 appered. I tried this several times to no avail - once not getting the error 28 but the system not booting and freezing on teh grub window.
Any ideas?!
Regards
Richard

I am not familiar with the boot_archive bit but I have used srss for ages without a problem like that. What kind of system is it on?

Will the Sun Ray Server Software 1.2 for Workgroup
Servers work on a Sun Blade 100?Yes, it'll work. An SB100 won't support many
concurrent Sun Ray users but it'll be OK for a
handful of users doing normal (non-multimedia)
work. Put as much physical memory into the box
as you can afford, and remember to configure an
appropriate amount of swap.

Sun Ray Server Software 4.2

Hi,
I have the Sun Ray Server Software 4.2 setup on two servers but have noticed in our FOG that the failover group has stopped working in that only our primary server is been shown and not the secondary server. Due to this all user sessions are connecting to our primary server. I have tried both cold and warm restarts of the secondary server and also physical reboots of both servers. I have also redone the utreplica.
Any help would be grateful?
Kind regards.
Gav.

First, make sure that the secondary server really is still running. 'ssh' to it and check that you get output from 'utgstatus' or log in to its SRSS web GUI and check its status, and if possible 'utswitch' a DTU to it and make sure that you get a session. If SRSS is not running then do a 'utrestart' and then check the previous set of log files (in /var/opt/SUWNut/log with .0 suffixes) for clues about what happened.
If the secondary server is running then its disappearance from 'utgstatus' on the primary means that the network has stopped delivering group membership announcements from the secondary to the primary. These announcements are sent as multicast by default. Some networks have trouble with multicast. If yours is one of those then you can tell SRSS to use broadcast instead, but this requires that the servers have at least one subnet in common (i.e. they both have interfaces connected to the same subnet) and for SRSS 4.2 it requires that you have the -01 patch installed. To use broadcast, edit /etc/opt/SUWNut/auth.props on both servers and set to enableMulticast property to false, then 'utrestart' both servers. ('utrestart' will temporarily interrupt sessions but will not destroy them.) Another alternative if you don't have patch -01 installed is to use 'utgmtarget' to configure unicast announcements in addition to multicast or broadcast. This will also require 'utrestart' on both servers after you create the 'utgmtarget' setting.

Sun Ray server software and Sun DSEE

I want to have a centralized user administration in the latest sun java 7 directory server. i want to set up the system in that the users of the sun ray thin clients will be authenticated from
the DSEE. Please assist me in how to make this work.

Basically, you Sun Ray server must be an LDAP client: it must be set up so that when logging in, it actually authenticates users against DSEE.
DSEE can be installed on the same host as the Sun Ray server, but it's not a requirement. On the contrary, in such a case, you've got to be
careful in the start order of services at boot time. So the easiest way is to have DSEE and the Sun Ray server on separate machines.
How to configure both servers is explained here: http://download.oracle.com/docs/cd/E18752_01/html/816-4556/ldapsetup-1.html
Or at least, it's a good starting point.

Solaris containers + sun ray server

just some theoretical question...
would it be possible to put a sun-ray session into a solaris container, stop it, move it to some other machine, and restart it there?
never played with containers and maybe i am compleatly wrong here...

well, i'd say that dhcp is not an issue. i am running srss without local dhcp and the clients in some other networks using other ip's/dhcp (i know -- unsupported config, but it has it's advantages).
i've just read some docs about containers, and it seems, since opensolaris b36 it is possible to stop containers and restart them on some other node... but it seems that patchlevels and kernel needs to be the same... ...so it would not be possible to move container+srss, update server A, move container back and update server B.
may you explain, in more detail, the CAM idea?

Cannot configure secondary Sun Ray server

Hi All,
I have just re-built a secondary Sun Ray Server (4.0) running on Sun Fire X2200 (AMD) Open Solaris X86 platform with the following commands, the primary identical server is still working:
1. On primary server.
# /opt/SUNWut/srds/lib/utldbmcat \
/var/opt/SUNWut/srds/dbm.ut/id2entry.dbb > /tmp/store
2. On secondary server for the rest of steps.
FTP this file /tmp/store from primary server to the /tmp directory on secondary server.
3. Follow the directions in the Sun Ray Server Software 4.0 Installation and
Configuration Guide to install Sun Ray Server Software.
4. After running utinstall, configure the server as a primary server for the
group. Make sure that you use the same admin password and group signature.
# utreplica -u
# utreplica -s <existing-primary-server>
5. Shut down the Sun Ray services, including the data store:
# /etc/init.d/utsvc stop
# /etc/init.d/utds stop
6. Restore the data:
# /opt/SUNWut/srds/lib/utldif2ldbm -c -j 10 -i /tmp/store
This populates the primary server and synchronizes its data with the secondary
server. The replacement server is now ready for operation as the primary server.
7. Restart Sun Ray services:
# utrestart -c
8. (Optional) Confirm that the data store is repopulated:
# /opt/SUNWut/sbin/utuser –l
However, the following issues still remain unresolved:
( i ) Only a few of the Thin Clients are connecting through secondary rebuilt server.
( ii ) As a result of ( i ), no load balancing of the number of connections between primary and secondary servers. Where is the script on either of the servers responsible for alternating the connections?
( iii ) An Oracle Common Desktop logon prompt is displayed on those Thin Clients that are connected through secondary rebuilt server, as opposed to getting a familiar MS Windows 2003 logon prompt, consistent with majority of those Thin Clients going through primary working server.
Any other troubleshooting material on this area would be very much appreciated.
Thanks in advance,
Jack

- So both servers are running, being a FOG and accepting connections ?
- check with the UI https://server1:1661 ... both servers should be there and visible
- output of utgstatus on both servers ?
something like
root@host02 <> : / > utgstatus
hostflags interface flags
xxx.yyy.zzz.0/24
host02 TN xxx.yyy.zzz.1 UA-
host01 TN xxx.yyy.zzz.2 UA-
- how do the the DTUs connect, e.g via the load balanced DNS entry sunray-servers with both servers ?
nslookup sunray-servers
Name: sunray-servers
Address: xxx.yyy.zzz.1
Name: sunray-servers
Address: xxx.yyy.zzz.2
Just give us here more info, I have two systems here, that load balance perfectly around 300 Connections, so it is feasible (Sun Ray 5.2.3 and VDI 3.3)

Bug or wrong configuration of the Sun Ray Server+DTU+17" and 24" screenres.

I have 2 DTU, one has a 17" screen with a resolution of 1280x1024 and the other DTU has a 24" screen with a 1900x1200 resolution attached. The setting of the Sun Ray server is configured only that registrated cards, can make an kiosksession to VMware View 4.6.
When I start the DTU's, there is nothing wrong. The correct screen resolution is displayed on the screen for both DTU's. When I put a smart card into the DTU that has a 17" attached, it's indicates the correct resolution. The problem starts when I hotdesk to the other DTU with the 24" attached to, the session what was builded on the 17" will be showed on the 24". So the the resolution is 1280x1024. With this action there's nothing wrong, because the kiosksession is made on the 17" and no disconnection is made, so this is a correct resolution at this point. When I pull the card out of the 24" DTU, the screenresolution will be still at 1280x1024. It's looks like the setting will be saved on the DTU. Only a restart of a DTU will turn back the good resolution.
When I do the same as the case before, but only I start at the DTU with 24" screen the kiosksession will start at 1900x1200. When I hotdesk to the Other DTU the kiosksession is still at 1900x1200, but only this time when I pull out the card out of the 17" DTU, The DTU will give the right screen resolution of 1280x1024
the DTU's are Sun Ray 3 Plus, it doesn't matter which DTU's I place, the problems seems like that the DTU will save the last screen resolution. I got 300 of these DTU's and try a lot of them, but still the same issue.
Note: with each case explained in this thread, the kiosksession will be started at first time, the kiosksession is not builded yet or has been disconnected.
This behaviour is with a standard installation and configuration of Sun Ray server software 5.1.2. No extra script is implemented. Also I tried the UTRESIZE script that I've found on this forum, but it didn't helped.
Is this problem a bug (known issue) or is this a wrong configuration of me? This is a big issue for me

I have also a lot of fun with different screens, so I walk the "hardwired" mostly when I run into my screen does not look like correctly.
utresadm -a -c MAC -t default 1280x1024@60 ... and then this is nailed, whatever you do with this box. Very effective especially for beamers ...
what you can set, utresdef is your friend, utresadm -p show all the devices overwritten in case you need to change for a new monitor. And finally utresadm -d -c MAC -t default clears the setting.

Monitoring Sun Ray Server health

I am interested in deploying Sun Ray Server as a component of a large VDI implementation. I want to be able to monitor the health of the Sun Ray Server software beyond the standard OS level stuff - number of concurrent Sun Ray Client connections for example. Is there an API (or some other mechanism) available for me to create an agent that can be monitored with standard monitoring software? Thanks!

Thanks for the info, however, I'm not looking for monitoring software - my organization already uses the IBM Tivoli suite quite successfully. I'm interested in more info on the specific Sun Ray APIs available to me to mine some health data. Thanks.

Sun Ray Server x64 or T2?

Hi,
I have been searching around looking for some advice/benchmarking for what hardware is best for Sun Ray servers. My plan is to use the Sun Ray VMware View Connector and so the Sun Ray server will only be managing the sessions rather than providing the desktop.
Therefore, would a T2 system give more consistent performance than a x64 system? and, how many Sun Ray sessions could be expected to be managed by a T5120 or a X4100?
Finally, is running the Sun Ray server in a VM a supported config?
cheers,
Simon.

We have found that x86 series server far out strip the T series boxes for Sun Ray.
A X4100 with 8GB RAM should be able to handle 100 odd sessions. We build for our Customers on a model of around 125 sessions per server. We used to use X4100 but have moved to X4140, if you bumped the RAM on these to 16GB you should get more.
Sun Ray runs poorly under VMware and if you need to go down that route run lots of little Sun Ray servers with no more than 20 odd DTU per server.
Hope this helps

Sun Ray Server Failover/ Load Sharing

Hi All
I have 2 sun servers which i want to use as sun ray servers in failover/load sharing mode.
I have 60 sun ray thin clients who will access these 2 Sun ray servers.
The users will be using the word, excel and presentation application and save there data in their home directories.
What i want to do is to load share these users between the servers so that any user can connect on anyserver and should be able to see his old data.
Is it a possible configuration?
if yes then please give me idea about how to do it.
I've the system admin document for sun ray server where it says about replication but doesn't tell what data will be replicated between the primary and secondary server.
Can we replicate the the user home accounts and directories as well?
Please assist me.
Thanks in advance..

Sun Ray Clients Software

Hello,
What software must be installed in Sun Ray Clients?
No software is needed?
Thanks.

There is no Software installed in the client
The Client loads a Firmware via TFTP . The End User does not
interact with this Firmware. The firmware fills the same function as
the BIOS does on a PC. But there is normally no user configuration possible.
The only possible situation where a user can configure the firmware is when the Sun ray is used remotely over the internet with VPN, Then a special version of the firmware is used and the enduser has to configure the VPN parameters , since he is nolonger connected to the INTRA-net DHCP service.
All SOFTWARE for the Sun Ray solution is loaded on the Server.

Sun Ray Software Compatibility

hi,
i want to know about the Sun Ray Compatibility with windows.
is Sun Ray server software is compatible with windows? OR
it needs only linux or Sol for installation? if it needs Linux Or Sol for installation then how can it provide Windows Env on the Desktop?
if someone has some Tech documents on how Sun Ray software works and configured, please inform me.
Regards,
Asghar

Sun Ray Server Software runs only on Solaris and Linux, so you need at least one Solaris or Linux system to control your Sun Ray terminals. After you have that you can run a Windows client program (such as rdesktop, Citrix or Sun's Sun Ray Windows Connector) on the Sun Ray server, connect that program to a Windows machine running Terminal Services and have a Windows desktop presented on the Sun Ray.
Sun Ray documentation for the current (3.1) release is at <http://docs.sun.com/app/docs/coll/1230.3>.

Sun Ray Software Training

I was wondering how most of you gained your knowledge in using Sun Ray Server Software? I received some basic training from a local Sun resource but only with a very basic configuration. Most everything else I've had to learn via the internet/forums. I have signed up for the Sun Ray Server Administration course being held in Massachussetts next month but the last one in San Jose was cancelled due to me being the only one that registered. I am able to get this working well with how we configure and sell it but I know it can do so much more than what we are doing now and am trying to get my skill level much higher implementing this solution. If anyone has any other suggestions for getting training/help I'd appreciate it.
Thanks!

Anyone know when SRSS5 (4.2?) is coming out? Funny I came across SRSS5 today, as just this morning we began research in what it would take to move to LTSP. We have entire departments running off SRSS4.1 on RHEL5. This has been a pretty good solution but Sun insists on keeping SRSS for Linux a poor product when compared to it on Solaris. Things like sound, USB thumb drives, etc are implemented TERRIBLY on their linux software (if at all).
I'd be willing to give SRSS5 a shot if it became available soon. Even a time frame (like end of 2009, spring 2010, etc) would help.
