Adding Linux extended nodes to Qmaster from Ubuntu machines

I realize this is both a complicated question and for some might be seen as a really easy question. I'm hoping for more the latter!
I have a Mac Mini hooked up to a network switch and I plug in my MacBook to set up a very basic cluster through Qmaster. It's the only way i can get jobs done in Compressor, neither of these machines have the specs suggested to really run Final Cut Studio at all, but this is a church and we just appreciate what we have.
In that same spirit, we have an old Dell PowerEdge 700 server I put Ubuntu Studio on running at 256 megs ram and about 2.8 Ghz. A Dell Inspiron 8200 laptop at 1.8 GHZ with 512 ram, and 4 Dell Optiplex with 256 RAM at 1GHZ. All old equipment I realize, but from what I've read it sounds like one can use these in Apple Qmaster as long as they are Unix based. So I've been installing Ubuntu on them (I'm a Linux newbie and the other distros are a pain to install on these machines.)
From what I understand, you put a UNIX system (like Ubuntu) on these, setup something like OpenSSH, and of course I have them plugged into the network switch with my macs.
The macs see each other and can create a cluster.
I setup a Linux box and it could see the mac through the terminal.
But the mac doesn't see the Linux box through terminal.
(Of course I'm new to terminal too.)
I opened up everything on the system preferences side for the mac for sharing services, no firewall setup, ect. I have a feeling there are a multitude of SSH things I have to set up on mac and linux that I just am unaware of.
I go to system preferences _ qmaster _ and try to set up extended nodes with the Mac Mini as an intermediary node (before anyone posts it, yes I've studied the Qmaster manual laboriously.) Where you type in hostname, username, and password, I've been typing in "ubuntustudio" as my hostname because that's what I set it up as when installing. I also set that as username. But every example I see posted lists the username with something like a domain name after it. I think maybe I'm not typing the hostname correctly or something, but I can't find any documentation on naming conventions for something like this.
Sorry if I sound like a newbie, on some of this I am. But our pc techs don't cover the linux machines under our contract, I'm sure Apple would charge me a ton if they were willing to help with this at all, and every support article I have found vaguely mentions that you CAN use SSH to add non-macs to the cluster, but just takes it as a given that you'll know exactly how to input the hostname and that it will work and all your setting will be perfect.
I just think with 6 machines running over 1ghz, collectively they could be a descent set of nodes and it just seems best practice to repurpose old equipment to death before buying new.
Thanks for your time

Thanks so much for your response!
I tried just typing in the ip addresses but to no avail. This was on an Airport Extreme and I'm going to try again on a network switch that has no internet connection. I'll post back here if it works. I don't think I have any firewall or anything that should be actively blocking on Ubuntu or Mac side but I wonder if there is something I should be unlocking that I haven't thought of.
If I have any success I'll let you know!
Oh this is latest version of Ubuntu Studio and Mac OSX btw.

What is the best client for ARD from ubuntu linux?

I attempt to connect to my mac mini running osx 10.7 from ubuntu linux using the default vncviewer application and the tightvnc client and I get to the login display but am unable to click on any of the users nor log in. I was successful from my windows7 laptop, but not from my windows xp HTPC--ultravnc gets to the login prompt, showed me the password field, but didn't allow me to change focus to that field, however, this isn't reproducable since I get a different behavior each time I try to remote in.

Back up all data. Update all third-party software to the latest version and remove any you don't need. Download the Yosemite installer from the App Store. Run it.

Selective XML Index feature is not supported for the current database version , SQL Server Extended Events , Optimizing Reading from XML column datatype

Team , Thanks for looking into this ..
As a last resort on optimizing my stored procedure ( Below ) i wanted to create a Selective XML index ( Normal XML indexes doesn't seem to be improving performance as needed ) but i keep getting this error within my stored proc . Selective XML
Index feature is not supported for the current database version.. How ever

OutOfMemoryError in TCP Extend nodes?

Hi,
We are facing a starnge issue in which a storage disabled tcp extend node is consistently occupying around 450mb of space?
Whenever we populate data in cache even smaller than 40mb the it starts filling up oblivious space in tcp extend nodes. Although the jmx console doesn't provide any details of data residing in the storage disabled extend nodes.
Ideally how much memory does the extend node storage disabled tcp extend node requires to run? Is it propotional to max amount of data loaded as a single unit. I feel the extend node should hold data for short duration and should free itself.
We are running on DGE cluster with 2 linux machines having 11 cache nodes of 1gb each. Each machine has 2 storage disabled Extend nodes with 500m each through which my client connects.
Thanks

Is there any standard way of deciding on the space required by Extend TCP nodes (Storage Disabled)?
In my scnario
We are trying to get a Map Object of 42mb from the cache. The TCP extend node to which the client connects is throwing OutOfMemoryError. We are runing 4 Extend Nodes of 600MB each.
By looking at the JMX console AvailableMB is < 200 MB consistently in Extend TCP Node (Storage disabled).
Why is this Memory not released after the data transfer is done?
Thanks

Logging in to Windows 8.1 from Ubuntu 14.04

I have 2 Windows 7 computers and a Windows 8.1 on a home network. I also have 3 NAS drives. I added an Ubuntu machine and was working on networking. I am sure I am missing something on Windows 8.1, but I don't know what. All machine
can see the NAS drives. All machines can see and access the Linux box. The Linux box can see all machine, but gets hung up on authenticating the user name and password. I tried setting up a local user. I know the password is correct.
Any idea if there is a setting I need to change somewhere?
Thanks

Hi Drew,
Try this:
1.Open Home folder(or any other folder, whatever)
2.Goto File-> Connect to Server
3.type your Windows IP with smb protocol e.g. smb://192.168.1.123/
4.Click Connect -> Enter Credentials.
In addition, this sounds more like a linux issue than a windows one. I suggest you post this question to ubuntu forum for further help.

Adding additional j2ee node

Hello,
we are running BI 7 - abap+java stacks with 16 GB ram (recently added)
i would like to know what is the thumb rule for adding additional j2ee node?
when is it neccassary to add additional j2ee node?
Regards,

Hi,
The JLaunch starts a Java program. It loads the JVM into its own address space and then represents the required cluster element. The program can receive notification from the JControl process via named pipes to stop the cluster element, and terminates, if the JControl stops running (fork emulation under Windows).
So Jlaunch consuming high CPU time means that server, dispatcher or bootstrap process consume it. If there are not enough system or application threads avaliable means that the engine must buffering requests for web application or system processes. Things to check in this case are:
SAP NOTE 1016241 - J2EE Engine hangs because of unsufficient system threads
SAP note: 716604 and upgrade JDK.
SAP note: 723909 -> set correct VM parameters
and if issue persists, then you will need to analyse the application causing teh leak...

NFS - Solaris 10 client from Ubuntu server gives Rpcbind error

Hello All,
New to Solaris, and I've been scouring the Internet to find a solution, but none have been produced. I'll start by giving you details about the setups, and then go into the error:
Server Setup:
Ubuntu 8.04
Exports file ->
/home/<folder> <Solaris 10 Server DNS name>(rw,no_subtree_check,async)
Client Setup:
Solaris 10
Set /etc/default/nfs to have NFS_CLIENT_VERSMAX=3
Ran svcadm -v enable -r network/nfs/client and then tried
mount -F nfs <Ubuntu Server DNS name>:/home/<folder> /mnt/test/
and all I ever get are Rpcbind failure - RPC: Timed Out and then it says it's retrying: /mnt/test
I've gotten the firewall out of the way, I can ping the Ubuntu server from the Solaris server and vice versa, and I'm able to mount the Ubuntu NFS share on another Ubuntu machine perfectly, but I can't get it to mount on the Solaris server. If I specify v3 of NFS, that doesn't change anything. If I specify v4 of NFS, I get the error that the file or folder doesn't exist on the Ubuntu server.
Any ideas? Any more info needed?

This is the exact same problem I've been having. My server is Ubuntu 8.10, and the client is Solaris 10. This is on my home network, so I'm pretty confident it isn't a network issue. I do NFS all the time at work between Solaris machines, but I'm stumped on this one. I've noticed there are similar threads on the topic with no real answer that I have found --
http://www.linuxquestions.org/questions/linux-networking-3/nfs-server-on-ubuntu-doesnt-play-nice-with-nfs-client-on-solaris-626508/
I did a dfshares from the Solaris box, and I actually get a response listing the shares. Even though I can see it I still can't mount it. Here is what I see:
bash-3.00# dfshares tabasco
RESOURCE SERVER ACCESS TRANSPORT
tabasco:/media/Shared tabasco - -
bash-3.00# mount -F nfs -o ro tabasco:/media/Shared /mnt
nfs mount: tabasco:/media/Shared: No such file or directory
bash-3.00#
NFS is working on the server, as I can mount it locally (see below)
root@tabasco:/# cat /etc/exports
/media/Shared *(ro,sync)
root@tabasco:/# mount tabasco:/media/Shared /mnt
root@tabasco:/# cd /mnt
root@tabasco:/mnt# ls

Yes... my server''s name is tabasco... remember it's a home network... and I like Tabasco... :)

Best Practice: Application runs on Extend Node or Cluster Node

Hello,
I am working within an organization wherein the standard way of using Coherence is for all applications to run on extend nodes which connect to the cluster via a proxy service. This practice is followed even if the application is a single, dedicated JVM process (perhaps a server, perhaps a data aggregater) which can easily be co-located with the cluster (i.e. on a machine which is on the same network segment as the cluster). The primary motivation behind this practice is to protect the cluster from a poorly designed / implemented application.
I want to challenge this standard procedure. If performance is a critical characteristic then the "proxy hop" can be eliminated by having the application code execute on a cluster node.
Question: Is running an application on a cluster node a bad idea or a good idea?

Hello,
It is common to have application servers join as cluster members as well as Coherence*Extend clients. It is true that there is a bit of extra overhead when using Coherence*Extend because of the proxy server. I don't think there's a hard and fast rule that determines which is a better option. Has the performance of said application been measured using Coherence*Extend, and has it been determined that the performance (throughput, latency) is unacceptable?
Thanks,
Patrick

OS X problems when restarting from Ubuntu

Let's start first speaking about my configuration.
I have a MacBook Pro 5,5 mid 2009 with 2 HDs: 1 is SSD (250gb), the other HD (1TB).
SSD: 1 single partition with OSX Maverick.
HD: 1 partition for data, 1 for ubuntu, 1 Linux swap, 1 bootcamp with Windows 8.
In both there are the hidden partitions for EFI and Recovery.
The problem:
Some problems came out when I installed Ubuntu 14.04 LTS natively on my HD.
I configured Refind (see Refit), resized the data partition on the HD, installed ubuntu and I've built an hybrid MBR through gdisk to bypass the limit of max. 4 partitions (considering that I already have bootcamp).
When I want to switch from Ubuntu to Mavericks, I click restart and thanks to Refind I boot directly into OSX Mavericks.
At this point 2 strange things are going to happen under OS X until I completely restart my macbook.
Some of them are:
- The system time is not correct. My timezone (UTC +2) goes to UTC.
- The trackpad click (not the tap) sometimes does not work. If I connect/disconnect or disconnect/connect my magic mouse, the click starts working again for a small amount of time.
- It happened one time that the login keychan got corrupted and I had to fully restore it.
I decided to write here since I didn't found similar problems over the internet. Do you have any suggestions?

Blocking Access from Ubuntu 9.04 Virtual Machine

Hi Everyone
We have blocked access on Perimeter Routers for Some specific ports like telnet , SSH etc
and as per access policy users are granted access within the organisation for Servers at Data Centre based on there IP addresses
If some body installs Ubuntu 9.04 Virtual Machine and then invokes virtual XP some how the user gets 10 series IP and still manages to access the servers
How can i block the same
While checking for IP Accounting on Router there are no traces on the Vitual IP but server login details shows the IP address from whcih accessed with source IP as 10.x.x.x

Extensions installed from Ubuntu vanish (shared profile with Windows)

My system dual-boots between Ubuntu and Windows. I've set up a shared profile between the two operating systems. Everything works fine for normal browsing.
When I add an extension from Windows, everything works fine -- the extension is visible from Windows and Ubuntu.
The problem: When I add an extension from Ubuntu and restart Firefox the extension is not installed. The extension is not in the list of installed extensions.
I presume there's something wrong with some value in the profile, any ideas what is incorrect?

I just tried an experiment, and I can uninstall from Linux. I installed a new extension from Windows, and then successfully removed it from Linux.

Migrating from Ubuntu - Question on ArchLinux install

Hello,
I am attempting to migrate a computer from ubuntu to ArchLinux. I'm not new to linux, but I am unfamiliar with ArchLinux. I've Installed ArchLinux from the wiki instructions without much problem, and when I reboot, it sends me to the command line. Is ArchLinux nothing more than a command line OS? It appeared to have a GUI (like nautilus for Ubuntu) in some pictures that I have seen. Is there a command to start up ArchLinux GUI from the prompt?

Thanks for the quick replies everyone.

Can't save multiple folders to external drive. Get: "The operation can't be completed because you don't have permission to access some of the items." when dragging large folders to mac os extended journalled external drive from OS 10.6.8

Hi
I am feeling VERY desperate!
After losing an external drive [dont ask....] -   I got another one : 2TB WD formatted properly [ OS extended journalled for mac ] ready for action to move my thousands of files and images and ppts in hundreds of folders across from the laptop to this drive because I travel a bit with the laptop and this is too risky not to back up at home.
But this message came up after starting on moving folders across [** and not straight away, sometimes after moving a folder when 4 of 6 gb of files across then the message comes up = very frustrating]:
"The operation can’t be completed because you don't have permission to access some of the items."
I am dragging mixed sometimes large complex folders to this os extended journalled external drive from my mac book pro OS 10.6.8 - it would take decades to move items one by one or even folder by folder and really confusing.
I have dragged-copied various small folders and files across successfully, but it is only working 50:50 and I can't leave machine with the idea of things copying eg: overnight - it just won't work....
I have been browsing google and find some people describing in CODE how they overcome this 'message'   .... but I [and I guess some other viewers of this in future & also in desperation] would need instructions for beginners.... to try this type of thing. I don't know any code.
How can this be happening - I feel ANGRY at APPLE !!!! for not posting easy fix instructions yet re; this, or better still updating software so it doesn't happen [ that I can find at least !!! ] .   There seem to be hundreds of people stuck with this stupid message and inability to back up their projects etc.
Can anyone help ?
Many thanks

hi Samberl
thanks a lot for the fast reply.
I was dragging folders from main folders on the laptop-desktop onto the external drive icon - to copy them across....
Your suggestion sounds very promising - I didn't know about 'cloning'.
Yes the idea is to backup the laptop -    I thought I would just move it all now, new - and then keep saving/dragging physically   across to the new drive myself each day or two...
Would this be the sizeof the internal hard drive = c.500 gb ?   =   under the HD icon on desktop is written :
" 499.76gb , 311.5 gb free "
I can erase and start agin on the new external drive - so this plan is to make two partititions, rather than the one at present, and make one of them 500 gb ?
I have found CCC [carbon copy cloner] googling - looks good.
When CCC site says it backs up the hard drive - would this mean all my files [over 100 gb] that are mostly in folders on the desktop, plus the others in itunes, iphotos etc found in the HD icon, would all copy across successfully [wherever they are in the computer ] ?
thanks again, hope you can clarify these things and then I will go for it.
It would be great and amazing if this 'lack of permission' message doesn't show up in the process of doing this ccc transfer - hopeful!

Error when adding a new node to RAC 10g

Hi all,
I have a RAC 10g environment test in Linux Red Hat Umbreakble 5 with two nodes. This RAC is fine on 2 nodes.
I want to add a new node (rac3) of the following way:
- The node 1 (rac1) is started and the instance ORCL1 is online.
- The node 2 (rac2) is offline. i.e the machine is off.
- The node 3 (rac3). The machine is on and already configured
So that when I execute the CRS_home\oui\bin\addnode.bat on node 1 and put the information of node 3 (Public node name, Private node name, Virtual host name) and press next I get the following message:
OUI-35000: Fatal cluster error encountered (PRKC-1071 Nodes rac2 did not respond to ping in 30 seconds) - Sure: The machine is off;
My question is: Can´t I add a new node on RAC if a node is off ?
Anybody can help me.
Thanks.

Interesting question.
You might have better luck getting an answer if you ask where people discuss RAC, instead of asking where people report documentation issues. (Go to http://forums.oracle.com and scroll down to 'Grid Computing' to see RAC forums.)

Extended Features prevents me from editing a form on another computer.

Extended Features prevents me from editing a form on another computer. I have to use this program at work but when I save it to a disk then try to edit it at home or vice verse I can't. This makes Adobe a horrible program to use.
I really HATE IT.
I can't contact a human being by email.
Adobe is a HORRIBLE company to work with.
I wish my work would have stayed with Lotus or what ever it is called now.
I doubt anyone even reads these posts.
DISCUSSED WITH ADOBE.

I have no clue what the right forum would be. would you enlighten me
please. I have wasted hours trying to figure out who I need to talk with. I
would think designers would know the most about the issue.
Obviously, I am wrong. I don't think anyone cares about my problem or for
that matter any ones problem with any Acrobat software.
