Re: [SunRay-Users] Performance tanks after upgrading to 1GB switch, had 100MB
Dear Craig and All, We here at Aberystwyth have too suffered fairly bad sunray performance for a long time. [By the way, in the end I abandoned using Sunray with Solaris 11 as while I got it working, there were lots of niggling problems and time ran out...] I have the hires_tick set. I have the two servers [two T5140s] connected to ports on exactly the same switch as our class room of 40 SunRay 2 units. [I also have a handful of sunrays connected via another linked switch such as the one I am using as I type]. I allow the servers to auto-negotiate with the switch, but I tell the switch to only offer 100mbps full duplex as part of the auto-negotiate and indeed, that's how the two ports connecting to the T5140 servers are shown when I look at current state on the switchor on the servers. I have wire frame window moves set. The switch is a Dell PowerConnect 5448. The performance of screen interactivity can get quite poor when we have more than 20ish students using the system. The two T5140s are often still showing as 90%+ idle on all CPUs even though clicking windows in tools like netbeans or Oracle Studio or moving/clicking tabs in firefox can be very slow. We had a student earlier using a PC with Xming coming in via the other ports on the T5140s and reporting massively better performance than when using the SunRays. Does anyone use a Dell PowerConnect 5448? Does anyone have a list of known good/bad switches to use in a Sunray network? Any other bright ideas/suggestions?

and display a Solaris 11 logon which worked fine. craig.ben...@oracle.com said: If that's how you been used to doing things, then there really is no reason to do anything but LAN only connections. On the DHCP server that was serving the PCs, you could set option 66 (tftpserver) and point it to the Sun Ray Server. This was you are provision/controlling the Sun Ray clients from via parameter files. There is also DHCP option 49, but option 49 will just let the Sun Ray find the server for a session, it won't tell it the firmware server. Our main DHCP server does *not* have an interface into the SunRay network. That's isolated to just the SunRays and the two interfaces to the SunRay servers. craig.ben...@oracle.com said: There are a few other options, such using DNS names. sunray-config-servers.fqdn is like option 66 sunray-servers.fqdn is like option 49 So instead worrying about making changes to many dhcp servers or messing with vendor class options, LAN based interconnects with these more standardized provisioning options is far easier. Now I am awake again, I will carefully try to check exactly what I do have and then I will go back to an older BE and run forward through this last phase again so I know more exactly what I did. I will then report back again. I need to know properly as I havbe the other server to deal with (assuming we do decide to risk going to Solaris 11 for our production teaching service) so I need some accurate instructions/records. I am also going to grab an old switch and set up a totally isolated network with a dozen of so SunRays and the interface to just the one server so I can be really confident no traffic is leaking in or out. We do have some VLAN traffic on some of our switch and trunk interconnections. I am confident that is not confusing the issue but a replacement totally isolated switch will remove even the faintest doubt. Anyway, thank you and the others, you all kept me going and the combination of things was really good. If I do get an accurate set of notes about making private interconnect work (if that is what I have achieved) perhaps that might be a contribution to the greater good. Off for a coffee, then I shall start looking, measuring and tinkering again. Dave Price ___ SunRay-Users mailing list SunRay-Users@filibeto.org http://www.filibeto.org/mailman/listinfo/sunray-users

My reason for going against the LAN option, as I said before, is that we have always seen various performance issues with SunRay screens refreshing and so what I am trying to do is to eliminate any network factors by having the SunRay traffic, and only the SunRay traffic all running in one isolated network. SunRay not leaking to other and others not leaking traffic to the SunRays. To make sure this was happening, I re-rigged five SunRays and the interface to the Solaris 11 SunRay server on to a new, completely isolated network swicth this morning and that's working fine. We normally run 40 SunRays fed from two T5140s. I have not yet added the set hires_tick=1 entry to /etc/system. I presume that will still work in Solaris 11?? These are used by students doing software development and/or learning to use Unix. So, some usage is low demand command line tools (editors, awk, sed, shell scripting an fso on) and other usage is more demanding software development, typically Netbeans being used to develop C and/or C++ code etc. I would be *VERY* interested to hear from other people using a SunRay service in this way and whether or not you have experienced problems with slow interactive response in tools like netbeans or web browsers etc. So, I am now going to backtrack to an earlier BE and see if I can again recreate what I have working now but with less random steps :-) Thanks, folks.

Re: [SunRay-Users] more help needed - Advice: Sunray on Solaris 11/SPARC with private interconnect
Dear Craig and All, craig.ben...@oracle.com said: Just curious as to what benefit you'd get over just LAN based and a manual DHCP config when the network wire itself is private? Well, the simply answer is because I have always done it that way :-) The longer answer (or at least my thoughts) go like this... We run a set of around half a dozen class C networks. Our end users with PCs, Apples and other devices connect to one of our networks. Most of our server class machines have mutliple interfaces and I tend to make them all live. Thus, most of our servers have multiple IP addresses. Thus, when users connect to a server (for whatever reason, computation, file access, web access or whatever) they reach (most) of the servers via a switched network path and their traffic does not cross any routers. On the same vein of thought, I have tried to run our SunRays on their own network with just SunRays, one interface from each SunRay Server and switches involved. Thus, SunRay traffic does not make its way on to otyher networks and other traffic does not make its way into the SunRay private network. As this was all very easy to create usingutadm -a nxge1 (or whatever on other architectures) I have always done it that way. I am trying to tackle two problems at the moment. One being users (students) complaining about the old fashioned interface of Solaris 10 and the other being that we have been seeing quite slow interactive response when running many applications displaying on the SunRays. [Things like netbeans, firefox and others stagger somewhat when moving between windows etc., plus the other sorts of problems other have noted.] On the poor interactive response front, I have done all the things people have suggested, setting hires_tick=1 in /etc/system, engineering the network so that the connections to our current two servers and the sunrays all make landfall directly on the same switch, dropping the switch port to the server back down to 100mbps to try to avoid packet loss anywhere and so on. Nothing makes much difference. I have tracked new versions of SunRay server software as they were realeased (one that came out last autumn made a big improvement I should add). Whenever I try to collect statistics on packet loss (or whatever) by using utcapture or looking at switch statistics I never seen to locate any bad numbers at all... Anyway, I have digressed. I do not expect swapping to Solaris 11 on the servers will improve performance of the SunRay service (but it would be nice if it did) but at least I may get the users believing they have a more modern user interface. Anyway, I will think more about what you say. I will need DHCP services for the SunRays, but if I read correctly, running utadm -A 192.168.199.0 would start a DHCP server one the sunray server and thus server the SunRays anyway - yes? And, providing I have this all rigged as a closed network (at the swicth/ethernet level) then I should not get spurious traffic in our out of the netwoerk unless the machine(s) running the SunRay server software starting forwarding IP packets between othjer interfaces and the SunRay serving interfaces. I guess I can control IP forwarding and route announcements using other tools (I guess ipadm and routeadm in Solaris 11). Anyway, thanks for info, thoughts and advice. I will have a go shorlty and post things again later. Thanks, Dave Price ___ SunRay-Users mailing list SunRay-Users@filibeto.org http://www.filibeto.org/mailman/listinfo/sunray-users

Re: [SunRay-Users] more help needed - Advice: Sunray on Solaris 11/SPARC with private interconnect
Dear Craig, Toomas and All, I have run utinstall, utconfig and utpolicy. I have also used ipadm to bring up net1 and allocated a static IP address 192.168.199.7 I have also updated the /etc/inet/hosts file so that its IP address from net0 (which also ends 7 but has a different class C netnumber at front) and hostname are on a new line and its name is not on the localhost line. I also manually moved the Xnewt and utdevmgrd from the patches into their normal places and checked permissions. With all that done, I created a new BE and rebooted into it so I can roll back if things go wrong. I also have LOTS of BEs# from previous milestones too. So, now I am trying to run utadm -A 192.168.199.0 Now, when I do that I get root@wiked:~# /opt/SUNWut/sbin/utadm -A 192.168.199.0 ### Configuring /etc/nsswitch.conf ### Configuring Service information for Sun Ray cp: cannot access /etc/init.d/dhcp chmod: WARNING: can't access /etc/init.d/dhcp.1674 /usr/bin/nawk: can't open file /etc/init.d/dhcp.1674 source line number 1 ### Error: Unable to stop dhcp services.

Dear Toomas, tso...@mac.com said: dhcpd is managed by smf now but you can create dummy script there and remove after... also beware the /etc/rc?.d directories;) yes, I had of course realised the SMF manages DHCP (as it does for most other things), but other than that, do you reckon utadm -A 192.168.199.1 will have set up dhcp configs o.k.? But thinking, it can't have as it has not asked me what ranges of IP addresses it can hand out. In the past, I have always been queried (but then of course I used -a which Craid said did not work). As I commented now many emails ago, I let our one DHCP server hand out something like 16 - 79 and the other hand our 60 - 123 (or whatever).

Dear Toomas, tso...@mac.com said: tbh, i dont know - I only have set srss on s11 without dhcp and only for lan enabled setup for soft client for test purposes:) the basic dhcp setup (dhcptab) is done by utadm -c, as you can verify with dhtadm -P :) with fake init.d dhcp start scrip, i'm sure you can get other bits done as well. Indeed, looking through the utadm script, it has the SMF reference to the dhcp server in it, line 116 says DHCP_FMRI=svc:/network/dhcp-server:default It sets a variable INIT_DHCP=/etc/init.d/dhcp; So, I reckon I'll edit that to point elsewhere and then I will grab a copy of the /etc/init/d/dhcp file off my Solaris 10 box and use that.

I copied in /etc/init.d/dhcp into a local directory I then bodged utadm to pick up my local copy.. then I bodged around trying to get the -A option working... then I tried to look at dhcp with dhtadm and pntadm but only had bits of stuff and... Then I hacked about with some /etc/hostname.net? files then I removed one, then I messed about with /etc/inet/hosts and then I thought I would have a final go at running my bodged utadm with the -a option again and, suddenly things seems to be playing the game... then I did utstart -c and then I went and restart one of my SunRays... first attempt it latched on to my (other) Solaris 10 server, then I tried again, and this time it latched on the the Solaris 11 server, updated its firmware, then gave a log on display and then I logged in to Solaris 11, on a private interconnect from a SunRay!! I had been taking copious notes, but then as frustration rose, I dropped into hacking and only taking partial notes! I now need to look back carefully through my bash history file and try to decide what caused it to finally work! I will then revert back to an earlier BE, make a new one and then try to repeat the final steps again taking proper notes again! I will not destroy my current BE and then if things go pear-shaped I can come back to this and try to spot differences.

Dear All, Firstly, can I say thanks for all the comments and notes so far, much appreciated. A variety of attempts to install SunRay software on Solais 11 all failed yesterday... [yesterday, I was attempting to install WITHOUT having firmware installed, which it seems to claim should work - I was going to let SunRays use their existing firmware]. tso...@mac.com said: after that you need to follow normal SRSS configuration docs, http:// docs.oracle.com/cd/E25749_01/E25745/ html/Installing.html note the kiosk mode is still not working. for s11 management, follow s11 docs, not express ones - there may be some differences. I seem to have to do more than that... utsetup bombs out after installing just the SunRay server software and does not enter the stages where it asks questions. I then went back to an earlier clean BE of solaris 11 and tried again using utinstall etc. followed by other tools, but more problems... One problem that popped up at the end of rrunning utconfig was... = ** The current policy has been modified. You must restart the authentication manager to activate the changes. *** /opt/SUNWut/sbin/utconfig[1306]: /opt/SUNWuttsc/lib/uttscadm: not found [No such file or directory] Configuration of Sun Ray Server Software has completed. Please check the log file, /var/adm/log/utconfig.2012_08_21_13:41:11.log, for errors. === even though /opt/SUNWuttsc/lib/uttscadm seemed to exist. When I try to run utadm, that needs me to edit the /etc/inet/hosts file to have machine name on its own name with it primary IP address and not on the localhost line... So, it seems that the main instructions in the admin guide are not sufficient and I am going to need some hybrid of the old opensolaris/solaris express type bodges mixed in with the new admin instructions... To remind folks, I am doing a SunRay install on a T5140 with a fresh Solaris 11 installation and wanting primary IP address on net0, Sunray private interconnect on net1. [We also normally configure net2 and net3 as we normally run our main hosts multihomed with live IP interfaces on several different class-C IP networks.] Has anyone got any definitive notes of a complete install? I'll post more later after I do some more experiments. I am trying again with SunRay firmware installed as well today.

So I am now looking at http://wiki.sun-rays.org/index.php/SRS_5.1_on_Solaris_11_Express as well as the advice given to me yesterday and I am reading the lastest SunRay admin guide (august edition). The wiki page has material about changing between different flavours of IP interface control and wiki says... svcadm disable network/physical:nwam svcadm enable network/physical:default But my fresh Solaris 11 installation already has the second enabled but also has another service... online 17:50:52 svc:/network/physical:upgrade online 17:50:55 svc:/network/physical:default So can I assume that's o.k.? Thw wiki also says... update /etc/hosts to specify a static IP address for your hostname, and eliminate your hostname from the localhost line edit /etc/hostname.INTF to contain your hostname, where INTF is your network interface name (see ifconfig -a output) edit /etc/netmasks to contain the appropriate netmask for your subnet create /etc/defaultrouter containing the IP address or hostname of your subnet's router But from what I can see, ifconfig -a now only shows interfaces which are active and it seems to me that the correct way to handle IP / interfaces is to use the ipadm program and routeadm and so on. I notice we also have routing related services running on our fresh Solaris 11 installation. svcs | grep rout online 17:51:04 svc:/network/routing-setup:default online 17:51:08 svc:/network/routing/route:default online 17:51:15 svc:/network/routing/ndp:default So, should I be editing /etc/hosts, /etc/hostname.INTF, /etc/netmasks and /etc/defaultrouter or should I really be making changes another way now on Solaris 11?? I don't (at present) need Sunray windows connector (SWRC) running by the way as we don't use that at present. We only use our SunRays to get to Solaris machines. Anyway, if anyone has either some complete notes, or can offer comments on how much I need to do over and above SunRay admin guide and whether or not I do need to do all or some of the things from the http://wiki.sun-rays.org/index.php/SRS_5.1_on_Solaris_11_Express wiki page..

Daer Bob, Thanks for email. bob.doolit...@oracle.com said: The basic model for Solaris installation is that LiveCD is intended for laptops or workstations But I can't use that anyway as I have SPARC (T5140). bob.doolit...@oracle.com said: and Text installation or AI is intended for servers. They install different sets of packages which target the intended model. multi-user-desktop is an optional package (group) intended for desktop servers (i.e. Sun Ray). I used the text installer (from DVD and controlling it via the service processor), but it did not seem to offer me any options of what package set to install. bob.doolit...@oracle.com said: May I suggest that instead of using LiveCD for Sun Ray, you use the Text installer and then install group/feature/multi-user-desktop. This will do several useful things for you: 1. It will install a more minimal package subset for desktops. I did not see it offer me that choice. From what I saw, and from what I read in the Note on page 16 of the March 2012 ediiton of Installing Oracle Solaris 11 System, it only installs the solaris-large-server package when using the text installer directly. Thus, after that I then installed the slim_install package (as as recommended then removed that group container leaving the packages it has sucked in intact) and then I also installed pkg install SUNWdhcsb SUNWdhcs SUNWdhcm pkg install /x11/library/libxevie pkg install SUNWmfrun SUNWtltk SUNWdtbas bob.doolit...@oracle.com said: 1. It will install a more minimal package subset for desktops. Our machines do sometimes run the odd cpu-resource-limited zone too so I really need more than just desktop. bob.doolit...@oracle.com said: 2. It will configure networking appropriately for a server instead of a laptop (e.g. no NWAM, static address) yes, I gave it fixed addresses and the SMF services that are live show that is the case. bob.doolit...@oracle.com said: 3. I will install the core dependent packages required by SRS (DHCP, CDE/Motif) I hope the packages I mentioned I had installed a few lines ago meet those requirements too. bob.doolit...@oracle.com said: 4. It will provide an SMF 'multi-user-desktop' service I don't seem to have that running. root@wiked:~# svcs -a | grep -i multi disabled 17:50:20 svc:/network/dns/multicast:default online 17:51:08 svc:/milestone/multi-user:default online 17:51:11 svc:/milestone/multi-user-server:default root@wiked:~# from what you say, should I see a service called multi-user-desktop too? bob.doolit...@oracle.com said: which you can enable to provide some useful optimizations for Sun Ray deployments (mostly restricted choices for desktop users to mitigate desktop features that don't scale well in shared environments). We'd be interested in feedback regarding experiences with that service. There's a document that describes how to configure it, should you care to: http://docs.oracle.com/cd/E23824_01/html/E26032/index.html I will have a look at that document before I go further. I have been tied up in a variety of meetings this morning so not gone any further today. I am presuming also that I will need to update the IP config (at least editing /etc/hosts) using the commands that Toomas suggested earlier anyway. As I noted in other emails, one of the commands (utadm -a net1) fails unless I manually change /etc/hosts anyway... I downloaded the new SRS etc fine. My problems are that if I try to run utsetup that bombs out and when I try to start again (on a new BE) and instead try to manually go through utinstall, utconfig, ... instead various of those are bombing out too. Anyway, thanks for advice, I will read that document and then try more things. I am keeping notes so perhaps I will have a full comprehensive set that may have value to others once I get this going (optimist here :-)) Thanks, Dave Price ___ SunRay-Users mailing list SunRay-Users@filibeto.org http://www.filibeto.org/mailman/listinfo/sunray-users

Dear Toomas and all, Some of the setting are already o.k. I believe. 1/. root@wiked:~# netadm list netadm: DefaultFixed NCP is enabled; automatic network management is not available. 'netadm list' is only supported when automatic network management is active. root@wiked:~# so that's already o.k. 2/. root@wiked:~# ipadm show-if IFNAME CLASSSTATEACTIVE OVER lo0loopback ok yes-- net0 ip ok yes-- root@wiked:~# so that is o.k. to start with I think. I want SunRay to pick up net1 as the private interconnect, so assuming things are like in the old days, it is probably correct that it does not show yet. ipadm show-addr display the fixed addresses I have allocated to net0 so that's o.k. too I think. root@wiked:~# svccfg -s svc:/system/identity:node listprop config/nodename config/nodename astring wiked root@wiked:~# so I don't need to set that. 3/.

So, I will edit that as I did yesterday to have the machine's name on a new line against it's IP address from net0. However, I think that then just takes me to exactly the state I was at yesterday and then after that, if I use utsetup I expect it to fail again as I will have changed nothing beyond what I had yesterday. Well, except I now have some SunRay firmware in place and I was trying without that yesterday. I will read what the others said before I try anything.

Enable LAN based interconnects and provide DHCP, and some sort of way from the Sun Rays to find the server on that segment, and you should be fine. o.k., I need to think about this I can clearly bring up my net1 interface and manually give it an IP address etc using ipadm [My machine in question normally gets given 192.168.199.7 for its sunray interconnect IP address.] Can I then use utadm -A 192.168.199.0 or does -A not work either? Would I need to also issue utadm -L on I don't want SunRay service running on the net0 interface though. So if I do have to issue utadm -L on would I then need to issue utadm -D x.y.z.0 (where x.y.z.0 is the range I have on net0).

Dear Marcel, Thanks for your detailed list of commands. There are a few parameter choices I think I will pick differently. I don't think I want to enable NSCM in my scenario for instance. I see also that you use -A and -L on to utadm and I wanted a private interconnect (-a) which Craig Bender says does not work on Solaris 11. I think I will have to hand craft things a bit ...

Re: [SunRay-Users] Advice: Sunray on Solaris 11/SPARC with private interconnect
Dear All, You will recall I asked for advice with regards to SunRay support on T5140s running Solaris 11. Perhaps I should add that (of course) our T5140 is a four-interface machine and we normally have 1/. nxge0 (now net0) as an interface to one of our normal IP networks 2/. nxge1 connected to the SunRay private interconnect (which also normally has another T5140 providing SunRay services too in a failover group with the machine I am currently trying to upgrade). I have the other machine handing out IP addresses via the DHCP/SunRay config in the (64 address) range 192.168.199.16 - 192.168.199.79. The machine I am trying to upgrade hands out IP addresses via the DHCP/SunRay config in the (64 address) range 192.168.199.80 - 192.168.199.143. 3/. nxge2 (now net2) as an interface to one of our other normal IP networks 4/. nxge3 (now net3) as an interface to one of our other normal IP networks We don't run 128 SunRays of course, this is just so so that both servers have enough addresses each that all SunRays can run fine when only one server is available to hand out IP addresses.

Dear Toomas, tso...@mac.com said: if you have contract, download latest from MOS for sure It seemed to want to give me the full versions from oracle delivery cloud rather than MOS. I got that and diff'd file against version I picked up a few weeks ago and both are them same. tso...@mac.com said: also, note while indeed you cant add patch with patchadd, the SRSS patch bundled inside the package can be installed manually - it has only 2 files to be copied into place (in reloc tree). if you dont feel comfortable messing with it, you can leave it and hope the s11 native SRSS will be out soon enough;) I have never tried doing that sort of thing. Are there any docs/pointers that woudl show me how to pull a Solaris 10 package apart? I will get that off patches on MOS and see what it looks like anyway.

[SunRay-Users] Advice: Sunray on Solaris 11/SPARC with private interconnect
Dear All, I am attempting to get the (unsupported) configuration of SunRay server installed on Solaris 11 on a T5140 (SPARC) with SunRay service only running on a private-interconnect network. I have tried various things today on a fresh install of Solaris 11, using various hints and tips from web sites etc but not yet got anything fully working. I have not yet found any advice precisely to the private interconnect configuration. To be clear, I installed Solaris 11 from a text installer off a DVD and then when booted, I added certificates for OS support (we have a contract), changed the package repository etc, added the slim_install package (and then removed the package as advised), created a new BE and then tried to install SunRay server srs_5.3.0.0-SunOS.sparc. Various things did install, but I never got to the end without something being wrong.. Anyway, I have now tidied up, removed the broken BEs and I have just created a nice fresh BE to start again.. So, any advice, any pointers?? As I commented at the start, we run SunRay service only on a private-interconnect LAN and not on a shared LAN. I can't find advice so far on that configuration with Solaris 11. Thanks in advance for whatever advice folks can offer.

Could you spell out exactly what commands you issued where. I'd really like to try this. We have been running last summer's badged OpenSolaris release plus SunRay with a trail of issues. Sometimes we got 10 days with no major problems (although always having the sort of screen update/performance things you have seen) and then chaos... We would start having SunRays dropping like flies as folks logged off. They get stuck on 26D. We have tried (I believe) all the things folks have reported related to this issue. I have various scripts that go around deleting things related to a given stuck SunRay and I can resurrect things for a while, but then they stick again.. All seems to us like some sort of race condition between X server stuff and SunRay server code We saw things having a higher probability of starting to go wrong with higher numbers of users, but nothing absolute.

Dear All, Can you try running snoop or wireshark somewhere and looking for the DHCP traffic? I don't recall wheether or not you described the topology of your network. Assuming you have a reasonable switch close to the sunrays you can probably get that to clone the sunray port traffic to another port and then look at all that traffic?
