Cluster with only two machines.

          Hi all,
          Can I make in weblogic6.0 a cluster with two machines. One Aministration and the
          other managed ?????
          regards, Juan.

Is'nt there a restriction for running All WLS cluster machines on the same
          port ?
          Or is it just for the Mged Servers ...

How to hook up a G3 iBook to a home network with only Windows machines?

Before I attach an iBook (Mac OS 10.3.9) to a home network with only Windows machines, what should I know? (I intend to connect the iBook to an Ethernet socket on my Westell modem+router.) My reason for doing this is to back up a million family photos in the iBook's iPhoto Library.
This is the iBook:
Machine Model: iBook (Dual USB)
CPU Type: PowerPC 750 (2.3)
Number Of CPUs: 1
CPU Speed: 800 MHz
L2 Cache (per CPU): 512 KB
Memory: 640 MB
Bus Speed: 100 MHz
Boot ROM Version: 4.6.4f1
System Version: Mac OS X 10.3.9 (7W98)
Kernel Version: Darwin 7.9.0
Please give me as much detail as you can stand to write, because I know nothing about Apples. It's for my dear old Dad, who has no other way to back up priceless photos.
For example, when things are working well and the iBook "sees" the Windows machines, how do I copy the iPhoto Library?
Thanks!!

Hello,
When I got my first mac this ( http://macs.about.com/cs/tipstutorials/a/xposxsharing.htm ) article helped me enormously.
It's very easy to write to the disc once you've set up the network.
On the mac locate the iPhoto library (normally open finder and click on pictures).
Open another finder window and locate the windows PC on your network, then mount the folder to which you will back up the iPhoto library.
Drag the iPhoto library to this folder.
Wait.
Wait some more.
When the copy is complete check the images can be accessed from the PC.
Unmount the folder from the mac by dragging it to the trash.
Congratulations.
Beware though, if you're like me you'll find this apple thing adicitve!!!

Cluster with 2 linux machines and ODI console - some questions

Hello,
I need to setup domain with ODI plugins (console etc.) on clustered environment. OS is Oracle Linux 6.3.
I've read this documentation:http://docs.oracle.com/cd/E13222_01/wls/docs81/adminguide/createdomain.html#CreateClusteredDomain and I have some additional questions:
- I know I need to install weblogic on 2 machines. Should I install Oracle Data Integrator on 2 machines as well?
- Creating domains, starting domains etc. I assume I should do this on first server? (for example, via ssh). Or I will need to login via cluster ip addres?
- MultiCast Address: this is not entirely clear for me. Should this ip aldready exist in my environment - should I configure my network interfaces somehow? Or, I simply need to provide any ip from 224.0.0.0 to 239.255.255.255 and this will work?

Can you describe all of this more detailed?

- Oracle JRFShould I do the same on second server machine? If not, how weblogic will know about other physical machine in my network and that it should be available to join my cluster? There is no domain and no admin server set on second server, should not I do this? There are a lot of tutorials describing how to setup cluster via config.sh od enterprise manager console, but:
- they describe how to add managed server to my cluster, but I need to know about physical machine servers. So, should I create managed server on second machine somehow? What about my domains - they should be re-created the same way on second server? I can't find any information about this, there are only enterprise manager screenshoots showing how to create managed server on the same physical machine and how to join managed servers into one cluster. But all of this don't tell me anything what should I do to complete my scenario.
- cluster ip addreess. I still don't understand this. End user should be able to access odi console via cluster address, am I right? So, is there any system network configuration required? How this ip addres is created?
- I have set up all of this (odi/weblogic/domain) on single machine and I have second server with only operating system installed (the same Oracle Linux). What's the simples way to join this second physical machine and make all of this working as clustered environment? Is there any step by step instruction/tutorial etc describing ALL steps should be done?
Sorry for basic questions, I'm really newbie with this and I hope you are patient enough to answer all of this ;)

Cluster with only 2 NICs, is it possible?

I am trying to setup a non-production 2 node cluster, problem is I only have 2 NIC ports avail since I can't spend any money on it. Is it possible to work around that and get the second node to join the cluster with one public and one private interface? Not having any luck and am curious if anyone has done the same and knows of some sort of hack to get around it? When node 2 first boots and tries to join the cluster, it is unable to communicate over the cluster interconnect. I understand this isn't the desired setup and voids the whole HA scenario, but this is just a proof of concept before moving a new production app over to SC3.2, which will not have this limitation.
Thanks in advance for any input.

A little more research in the interconnect not working I've found two common causes that people have discovered, ipfilter and kernel patch 138888-01. I am not using ipfilter, the service is disabled, and as I understand it, kernel patch 138888-01 and above only cause this issue if connected via a switch. My cluster nodes are connected directly by a crossover cable. Is this still possibly my issue, or should I keep digging? One node is a T2000 with e1000g interfaces, so that also lines up.
Thanks again..

When I log onto my macbook, my user account isn't showing up. All that shows up is a gray screen with only two boxes saying "Name" and "Password". How do I fix this?

There was one time where my wi-fi wasn't connecting so I tried to turn it back on. A window popped up but I had alrdy clicked enter before I read it, but it said something like "...will change settings, is that okay...?" And then wi-fi still would not connect. So I tried restarting my computer, but when it turned on, my user account did not show up and all there was on the screen was two boxes that asked for name and password. I was the only person using my macbook so I never set up a password for it. Has anyone had this problem? How do I fix this?

Since I'm not in front of your computer I can't tell what you see - I can only guess and give a hint. So once again, if the disk name on your Mac is "Macintosh HD", when you boot in Recovery Mode, and start up the Terminal in "Utilities" menu, and then type in the command:
    df -k
you should see a list of "volumes" - one of which is named "/Volumes/Macintosh HD" (but yours could be anything) and in that folder there is another folder called "Users" and in that folder is the names of the home directories of the user accounts (and the names that you can enter into the login screen) that you are looking for. So if you are not familiar with using the Terminal you should say so and I can give more details. But assuming you're OK with typing in commands to theTerminal this is what I would try:
    ls -l /Volumes/Macintosh HD/Users
and you should see something like the following (my disk name is "Yosemite" so I typed "ls -l /Volumes/Yosemite/Users")
ML9Book:~ xxxx$ ls -l /Volumes/Yosemite/Users
total 0
drwxr-xr-x+ 11 Guest      _guest   374 Oct 25 19:23 Guest
drwxr-xr-x+ 33 Jack       staff   1122 Oct 24 10:49 Jack
drwxrwxrwt   13 root       wheel    442 Dec 27 2013 Shared
drwxr-xr-x+ 38 admin      staff   1292 Oct 25 16:59 admin
drwxr-xr-x+ 15 x13        staff    510 Oct 23 22:41 x13
drwxr-xr-x+ 12 514        staff    408 Oct 23 12:24 x14
So now reboot your mac into normal mode - and you will see the login screen with the two empty boxes.
So the above output tells me that there are 3 users - Jack, x13 and x14 (there is always a Shared user and there might or might not be a Guest user since it depends on how your setup was setup) - and these 3 are the names that I could try and enter into the login screen (in the top or first box). You can try no password, but I don't think you can create accounts without passwords, so this will likely fail. In that case you need to reboot in recovery mode and run the Terminal command again (from the Utilities menu) and do a resetpassword command. Another window will pop up and from there you select the Volume (in my case I selected the Yosemite volume - in your case you would select the "Macintosh HD" if that is what your volume name is). Then select the user account you want to reset the password from the drop-down list of user accounts (it will show you the long and short names, and the short name is what was in the listing above from the "ls -l" command), then enter the new password in the indicated box, and then enter it again in the next box, to make sure you didn't make a typo, and enter a password hint in the last box (optional). Then click the "Save" button and you will see another dialog box pop up telling you that the password was changed but not the Keychain password (hopefully you remember this one) - click the OK button then reboot back in normal mode (click on the Apple logo in the top left corner of the screen and click on Restart).
Does this help?

Drag and Drop game with only two targets

I created a drag and drop activity where their are five boxes that are supposed to go in to two columns in any order. I found a tutorial online that I based this activity off of.
The problem is that the tutorial shows you how to make a target for each mc which has worked for all the activities I've made except for this one where I need only two targets. How would I change it so I can have multiple mc's drop on to one target?
This is my AS:
var score:Number = 0;
var objectoriginalX:Number;
var objectoriginalY:Number;
growing_mc.buttonMode = true;
growing_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickupObject);
growing_mc.addEventListener(MouseEvent.MOUSE_UP, dropObject);
gorging_mc.buttonMode = true;
gorging_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickupObject);
gorging_mc.addEventListener(MouseEvent.MOUSE_UP, dropObject);
dormancy_mc.buttonMode = true;
dormancy_mc.addEventListener(MouseEvent.MOUSE_DOWN , pickupObject);
dormancy_mc.addEventListener(MouseEvent.MOUSE_UP, dropObject);
cystform_mc.buttonMode = true;
cystform_mc.addEventListener(MouseEvent.MOUSE_DOWN , pickupObject);
cystform_mc.addEventListener(MouseEvent.MOUSE_UP, dropObject);
hosttrans_mc.buttonMode = true;
hosttrans_mc.addEventListener(MouseEvent.MOUSE_DOW N, pickupObject);
hosttrans_mc.addEventListener(MouseEvent.MOUSE_UP, dropObject);
function pickupObject(event:MouseEvent):void {
event.target.startDrag(true);
event.target.parent.addChild(event.target);
objectoriginalX = event.target.x;
objectoriginalY = event.target.y;
function dropObject(event:MouseEvent):void {
event.target.stopDrag();
var matchingTargetName:String = "target" + event.target.name;
var matchingTargetisplayObject = getChildByName(matchingTargetName);
if (event.target.dropTarget != null && event.target.dropTarget.parent == matchingTarget){
event.target.removeEventListener(MouseEvent.MOUSE_ DOWN, pickupObject);
event.target.removeEventListener(MouseEvent.MOUSE_ UP, dropObject);
event.target.buttonMode = false;
event.target.x = matchingTarget.x;
event.target.y = matchingTarget.y;
score++;
scoreField.text = String(score);
} else {
event.target.x = objectoriginalX;
event.target.y = objectoriginalY;
if(score == 5){
response_mc.gotoAndStop(2);

var matchingTargetName:String =(event.target.name).substring(0, 1);
Change the name of the target to A and B and the mc A1, A2, A3, A4... and B1, B2,B3...

VMotion with only two hosts make any sense?

Glad to help :)
VMotion is awesome as an extra freebie, but on its own, just not worth much.
But it is a good reason to look at alternative platforms as VMotion, HA and tons of other features are free with all packages of VMware's competitors. VMware's value proposition that used to be very good has mostly evaporated these days.

rodmanfrowert wrote:
I can replicate and migrate VMs with Veeam between two hosts as it is. What would VMotion bring to the table that Veeam can't do now? Can VServer/VMotion "premigrate/replicate" itself to the secondary host but remained turned off and only activate in the event that the host where the primary VCenter Server were to fail? Or am I speaking nonsense?
VMotion is seamless, Veeam doesn't compete. VMotion does not require the machine to be off during the move. It's invisible to the end users (when it works - I've seen companies have outages from thinking VMotion was safe to use when they didn't have a green zone to bring the systems down. It encourages hubris.)
VMotion is not for protection, it is for maintenance. HA is for failure modes.

How do I hook up a G3 iBook to my home network with only Windows machines?

I'm completely ignorant of Apple technology but pretty good for a novice with Windows PC's. To help a family member with an iBook (Mac OS 10.3.9) back up a gazillion family photos (at least 3.2GB in the iPhoto Library), we want to connect his iBook to my home network with two Windows machines (one of which is connected via UBS to an external drive for backup). But before I just connect his iBook to an Ethernet port on my Westell modem+router, what should I know?
I need to know all the basics and all the steps, in as detailed a manner as you can stand to tell me.
And when it all looks good, what are the steps to copy the iPhoto Library to a designated spot on one of the Windows machines (or that external hard drive)?
By the way, this is the iBook:
Machine Model: iBook
CPU Type: PowerPC 750 (2.3)
Number Of CPUs: 1
CPU Speed: 800 MHz
L2 Cache (per CPU): 512 KB
Memory: 640 MB

Smart collection containing matches with only two keywords

I have added keyword tags to all my photos with the names of the people in the picture. I then created a smart collection with two names in it. For example Jessica and Ryan. That collection then returns all pictures that have Jessica or Ryan in them. I am trying to get pictures than contain both Jessica and Ryan, but not other names. The only way I have figured out how to do this is by entering in the other names in the doesn't contain field. That seems like a lot of work when I have many other names, and it must be updated each time I add new keywords. Is there an easier way?

There's no way built-in to LR to do what you want without listing every keyword you want to exclude. The Any Filter plugin lets you do it, though you need to understand boolean expressions. See the "Exactly one person in the keywords" example for how to match exactly one person. To get exactly two people, you'd define the filter:
All of
Explicit Keywords = Ryan
Explicit Keywords = Jessica
Explicit Keywords all items
Some of
Keyword = Ryan
Keyword = Jessica
None of
Keyword subkeyword of People

Using Caching Server with Only Two Macs?

I'm currently running OS X Mavericks (10.9.4) on both of my Macs (2008 MB and 2010 MBP). We have a limited Internet download allotment, so I am trying to find ways to reduce the number OS X system update downloads. Someone suggested that I take a look at OS X Server, because it has a Caching Server, which would download the update once and install from a local location when other Macs updated.
Given that I only have two (2) Macs, and one of those would have OS X Server, would that work for me?
Or would the fact that one of my Macs would be running OS X Server make the updates to it incompatible for my other Mac? If that was a problem, would installing OS X Server on both Macs, but only running the Caching Server on one of them resolve the issue?
I don't need OS X Server for anything else.
Thanks!

We have a NetGear router/firewall between the ISP's satellite modem and our computers (my DH's two MS Windows PCs & my two Macs). All of our computers are connected to the network via ethernet cable (wireless network disabled).
My Macs are both network configured with:
     Configure iPv4: Using DHCP
     Subnet Mask: 255.255.255.0
     Router:     192.168.1.1
     DNS Server:     192.168.1.1
MP IP address: 192.168.1.6
MBP IP address: 192.168.1.2
But, I don't know whether those are static or not. I tried switching my Macs' cable ports on the router, but that did not change the IP addresses. I realize that didn't prove anything, though it would have if the IP addresses had changed.
I used to be able to download updates from an Apple support web page, but things are not so simple anymore. I had a discussion about this a while back at in the Safari Community.
https://discussions.apple.com/message/26456050?ac_cid=op123456#26456050
Aside from the suggestion to install OS X Server, a couple suggestions were made for manually downloading or copying a package:
Download a log from an arcane URL; try to find the appropriate update in that log; download the update using the URL in the log file. I can readily see a couple downfalls in this scenario:
The arcane URL could be changed, so that I would no longer know its location.
I could easily select the wrong update from that log file.
Do the update on one Mac, watching folder /Library/Updates to copy the downloaded package. However, that package would automatically be deleted by the system, so I would have to be able to do the copy prior to its removal. I'm not clear as to how this would work, given that the download and installation are automatically performed, and I have no indication as to when the former ends and the latter starts.
In either case, the downloaded packages would not make any suitability checks, so I could easily mess up a system (though it would probably not be likely if I keep my Macs OS synchronized). Still a trashed system can be a headache even with good backups, due to the time it would take to restore a system. That's why I considered going the OS X Server route, but I know about zilch when it comes to networking.

Cancelling with only two months left to go... or s...

Having taken out an 18 month contract in 2012 (Nov) We were happy BT users.
In august 2013 we moved house - taking our broadband with us. All went smoothly.
The landlord has decided the sell the property we live in meaning that two months before the contract is due for renewal we're moving out.
We're moving back in with the parents whilst we look for another place to live. Unfortunately upon ringing BT to discuss possible solutions I am told that it'll cost £170 to cancel early...
I ask whether its possible to wait for the extra two months but cancel my line rental and simply pay the remainder of broadband and phone usage. To which I am told that by moving house I have extended my contract length - at no point during my calls with BT was I made aware of this. When I asked why the answer i received was because a new phoneline was installed at the property. There was an existing phoneline at the property, which was BT and again no one at BT ever suggested otherwise.
I am happy to pay the two months worth of internet useage etc £27pcm until my contract is up but what I don't understand is why and how they have extended my contract without sending me revised agreements or even discussing this with me.
I am more than happy to compramise or at least speak to someone with the authority to compramise with me. I'm astounded by how difficult this is especially as BT own the majority if not the entire intrastructure of the area if not the UK.
My issue is that when we move into our new address (date unknown) we would've continued to use BT and probably extended the contract to BT TV too, however it seems that BT don't seem to worry about brand loyalty or future earnings.

UPDATE,
After numerous calls with BT to actually descipher when my 'contractual obligations' terminate with them I have been given several dates. its seems that no one is actually sure when my contract ends with them!?
I spoke with customer care this afternoon 1:30ish and I had a very helpful woman deal with me. She was incredibly paitient and when I asked her at what point I had been made aware of my contract extension she couldn't tell me. The only corrispondance I had recieved was an email saying that my service was working...
She also agreed that it sounded odd that I would cancel a 18month contract and take another one out for no gain in performance or benefit.
Looking around online it seems that this is common with BT and there are several cases whereby their terms and conditions do not hold up.
I really wish what few moderators there are on this site (i'm really surprised that BT don't dedicate more people to this place) will be able to assist me some how.
Otherwise I'm waiting on Lindsey Jones (sp) to call me...
my issue with all of this is that at no point has anyone told me explicitly that by altering any service with BT i therefore extend my contract length with them.
It is all very well citing 'terms and conditions' BUT something as serious and costly as extending contract lengths should not be hidden away. the company has a duty of care to inform the customer that above all else.
I have asked for a copy of recordings to be sent to me under the freedom of information act, however I was promised an email with the correct form today - so far nothing has turned up...

How to deploy a MDBean into cluster with only one JMS server instance running on one of the cluster servers

          I am trying to deploy a MDBean in my cluster ( two servers). The MDBean requires
          the destinestion has to each cluster server. It means that I have to deploy my
          JMS server over the cluster. This will result multiple destinations (queue or
          topic) are created.
          Is there a way to run one JMS server with a clustered MDBean?

[SOLVED]Multiple servers/services with only one machine

Hello,
First of all, thank you for taking time to read this post.
Long story short: I had a machine laying around so i decided i would use it as a router/wireless access point since my isp router isn't working so well, but since the machine is not working anymore, and i don't have the resources(a.k.a. money) to fix it, i decided to use my main machine instead and make my laptop my main machine.
I have been reading the arch wiki regarding how to make a router and a wireless access point, but then i remembered something, what if i decide i need another server(http/https, ftp, NAS, IRC) which i might want, could i use virtualbox?
So my question is: can i have my computer with arch serving as a router + wireless access point and on the same machine, virtual machines with arch running other services? If i kept the files from this servers, like the www folder, of ftp folder, on the host machine would this be a security risk? This not intended for a enterprise environment, only here at home.
Thank you.

That would depend on the traffic If it is just for you or your LAN, probably not a problem (unless you are streaming video to a bunch of machines). <Sarcasm>OTOH, unlike others, you might want try to run an entire national health care sign-up site on it * </Sarcasm>

Sorry i didn't see you answer befores i posted my last. It would be only for my Lan, only serve i would run to the Internet would be SSH.. And no streaming video

On opening, the browser comes up with not an address navigation bar, but with only two google search windows. How can I make it open with an actual address line?

It's all been said in the question.

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F).<br />
If you are in full screen mode then hover the mouse to the top to make the Navigation Toolbar and Tab bar appear.<br />
You can click the Maximize button at the top right to leave full screen mode or right click empty space on a toolbar and use "Exit Full Screen Mode" or press F11.
If the menu bar is hidden then press the F10 key or hold down the Alt key, that should make the menu bar appear.
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"

Can not get two instances to join same cluster even on same machine

On a RedHat Linux box, I have failed to get two instances of coherence to join the same cluster. I have managed to get the muticast test tool to show that packets are being sent and received. To do this, I had to:

However, I could not get the following to show that two instances are joining the same cluster... When I start to instances, both of them create a new cluster with only one member in each.
java -Djava.net.preferIPv4Stack=true -jar lib/coherence.jar
and obviously, when I try to start two instances of the sample application, I get the same problem.
java -cp ./lib/coherence.jar:./lib/tangosol.jar:./examples/java -Djava.net.preferIPv4Stack=true -Dtangosol.coherence.localhost=172.16.27.10 -Dtangosol.coherence.localport=8188 -Dtangosol.coherence.cacheconfig=/cache/explore-config.xml com.tangosol.examples.explore.SimpleCacheExplorer

Thanks for that... I ran:
jdk1.6.0_13/bin/java -Dtangosol.coherence.log.level=6 -Dtangosol.coherence.log=/my1.log -Dtangosol.ccacheconfig=/cache/explore-config.xml -Djava.net.preferIPv4Stack=true -jar lib/coherence.jar
and then
jdk1.6.0_13/bin/java -Dtangosol.coherence.log.level=6 -Dtangosol.coherence.log=/my2.log -Dtangosol.ccacheconfig=/cache/explore-config.xml -Djava.net.preferIPv4Stack=true -jar lib/coherence.jar
from the same machine and get the following from the log file of the second run (my2.log)
