Live Migration only using one live migration adapter

Hi,
I have a 2 node cluster spanning two buildings, 4 switches (2 in each building), 2 live migration NICs in each server. I have NIC1 going through switch 1 and NIC2 going through switch 2, same in the other building.
everything talks fine to each other. I decided to team the Live Migration networks so I can get more transferring at once (getting 2Gbps instead of 1, this seemed like a good idea at the time but when I ran a test scenario of failing one of the switches
the live migration was unable to complete (despite the switches being stacked together, maybe I have a config issue I dont know).
so I destroyed the team and thought I'd have two seperate live mig channels, i select these two live mig channels in as live migration networks in failover cluster manager. when i try to live migrate a bunch of VM's it is only using the one adapter, no matter
how many VM's are going down there it will deal with 2 at a time (as per hyper-v settings).
the question is, why is not using my other live migration channel even though that adapter is configured correctly, I have even moved it up in the list and then it will use it so i know it works, but it won't use both together...?
thanks
Steve

Live Migration uses the first network interface in the order you configured it. As far as I know the second interface is only used when the first interface becomes unavailable. But don't pin me on this. Now back to your NIC teaming, because there
is one thing you should know:
When you configure a NIC team without a switch assisted (LACP) configuration your team will have a 2x1Gb outbound and 1x1Gb inbound connection. This is probably why you only get 1x1Gb througput.
When you configure a NIC team with a switch assisted (LACP) configuration you team will have a 2x1Gb outbound and 2x1Gb inbound connection. Such a NIC teaming configuration is in fact a port-channel / ether-channel like you would configure between switches.
This is an optimal configuration.
I hope this information makes more sense to you. If you have any questions let me know.

HT201342 How can I add an e-mail address to my existing icloud addresses? I currently only use one and I would like to ad two more?

How can I add an e-mail address to my existing icloud account? I curently only use one of the three.

Each iCloud account only has a single iCloud account. If you want, you can add up to 3 alias addresses that will receive email in the same iCloud inbox, as explained here: http://support.apple.com/kb/PH2622.

Can I install CC on three computers - I only use one of them at a time?

I'd like to use CC on three computers in three cities where I travel - I only use one computer at a time - is this possible with a single license? If so, how?

As long as you sign out of at least one of them you can. Sign out before you depart from a given city and you should be set to sign in at another.

Since installing an icon-editing add-on, I can't open tabs any more / I can only use one tab at a time.

Ever since I installed the add-on Favicon Picker 2 that lets you change the bookmark icons, I can't open tabs any more. The second tab will open, but if you try to go to a site, the FIRST tab redirects to that site. Basically, I can only use one tab at a time. Is there any way I can keep this add-on and use tabs?

Oh, wow - look at that, you're right :) I didn't want to uninstall the add-on as I like the feature, but simply by disabling it you can keep the new icons AND use tabs. Thanks dude!
(The add-on is Favicon Picker 2 0.6.2.15 by the way - some of the user reviews report the same problem.)

2 atv's both have home sharing enabled but one asks to turn on home sharing on my pc but it is on so can only use one at a time to watch movies from my computer

2 atv's both have home sharing enabled but one asks to turn on home sharing on my pc, but it is enabled on pc so I can only use one at a time to watch movies from my computer

Both atv,s are on the same network, they are wirless and the computer can see them and they are named different.
what ever one i switch on first gets to stream from my computer and the other one asks for home sharing to be switched on, then if i switch both off and start the other one first it gets to stream and the other one which worked asks for home sharing to be turned on. i have hidden all functionality, netflix etc as these are for my 7yr old kids.

AME is only using one processing core out of six.

I have not been able to figure out why AME is only using one of the six processing cores that I have in my Core i7 hex core processor. I'm running Windows 7 Ultimate 64 bit and the latest version of AME 2014 CC. When I render in Premiere Pro CC 2014 all cores are utilized. The codec that I'm using in AME is "YouTube SD 480P 29.97 - H.264". The video that is being encoded is fairly complex but it is only 30 minutes long and AME is estimating 18 hours to completion. That seems pretty excessive for that length of video.
Any help would be greatly appreciated.

Hello,
see >>> http://helpx.adobe.com/creative-cloud/help/install-apps.html here >>> How many computers can I install on
I quote: You may install software on up to two computers. These two computers can be Windows, Mac OS, or one each.
If you install on a third computer, it will request you to de-activate on the other two computers. You can then reactivate one of the previous two computers, and use Creative Cloud apps on it.
Good luck!

Why only using one CPU

Just noticed when importing CD into iTunes on my MacBook is only uses one cpu, with activity monitor it show 98-100% CPU and never goes over 100%
My fans also run when importing, I use lossless.
Why not use more CPU speed?
R

I believe only applications writen to do so will take advantage of dual processors. I guess iTunes has not yet been updated for dual processor use.

Dual G5 only using one processor in Logic 8

So...
Why does my Dual G5 only use one of the two processors in Logic 8? The one processor will go to max, stop the song from a cpu overload, yet the second processor never kicks in.
Please help! U_U
Thanks,
bp

it seems that the buffer settings on audio preferences are too small.
use this setting:
I/O Buffer Size: 512
Process Buffer Range: Large
Or... you are using some heavy third party Virtual Instrument that don't support Altivec on PPC processors.
(many software houses make good plugins that works fine on Intel processors but they forget to use Altivec implementation for PPC Mac side)

Multisim 11 only uses one CPU core during simulation

Hi,
Just recently I've been using MultiSim again, v11 if that matters, and simulating goes slow, to my opinion that is.
Now there are two things that I've noticed:
- Multisim only uses one of two CPU cores during simulation, not both;
- I've enabled CPU throttle (AMD's Cool'n'Quiet) but corespeed remains very low even though Multisim needs CPU power while simulating.
The simulating of a NE555-based LED-flash circuit requires about 28 seconds to get to 100ms in the simulation. Now if I can get the CPU to throttle up, by for example having Prime95 stress one of the two cores, then the simulation only requires 12 seconds to get to 100ms.
So here are my two questions:
1. Is Multisim 11 capable of using more than one CPU core while simulating? If yes, how can I get it to use more than one?
2. Probably not the right forum to ask, but is there a way to force Windows 7 Ultimate x64 to throttle up the CPU when Multisim starts simulating? Since Multisim does not seem to stress the only core it uses enough to throttle it up. Using Prime95 on one core does trigger a throttle up.
With regards,
Bart Grefte
Relevant specs:
Windows 7 Ultimate x64
Multisim v11
AMD A4-3400
16GB RAM

Completely forgot this topic....
Is there a good reason why there is no multicore support? Multisim can certainly use it for simulating.
As for the CPU throttling, I found a batch that can increase/decrease the "minimum processor state"-setting and it works immediately, no reboot required.
@echo off
powercfg.exe -getactivescheme > "%userprofile%\appdata\~apo.tmp"
set /p v_currentscheme= <"%userprofile%\appdata\~apo.tmp"
set v_currentscheme=%v_currentscheme:~24,36%
del "%userprofile%\appdata\~apo.tmp"
powercfg -setacvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -setdcvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -s %v_currentscheme%
exit
Usage is simple:
Start -> run -> c:\pathtobatch.bat 100
for "minimum processor state"-setting at 100%
Start -> run -> c:\pathtobatch.bat 5
for "minimum processor state"-setting at 5%
Please note that "set v_currentscheme=%v_currentscheme:~24,36%" is not the same for every language. The original batch had "set v_currentscheme=%v_currentscheme:~19,36%" (most likely for the English version of Windows 7), but since my Windows install is in Dutch, I had to change it in order for it to work.
Running the batch with @echo off removed will show why.

Pages '09 only uses one processor core?

Hello,
some days ago i had to open a document containing nearly 2.000 pages. Don't ask why.
Working with this document was quite complicated because Pages was responding very slowly. I used the activity monitor to see what was going on and i recognized that Pages only uses one core of my eight core MacPro.
I tested iWork on my iMac and MacBook Pro (both DualCores) as well: same problem.
Does iWork only use one processor core?
Kind regards,
roman

How much memory do you have in your system? I'll bet if you check activity monitor (applications/utilities) and go to system memory tab therein you will see lots of page outs. This happens with huge docs and little memory as the doc is being swapped between active operating memory and the hard disk The only way to solve this problem is to get more memory (not storage) in your system. For a 2,000 page doc you're going to need lots and lots and lots of extra gigs of memory. By the way - how big is the too big file of yours?
Number of processor cores isn't going to solve the issue if you have pageouts. It is a system memory/size of document issue and completely unrelated to how many processor cores you are using.

Push live, but not using one of my 5 freebies - client will pay

I did this once but can't remember the sequence.
Belong to Creative Cloud which comes with 5 free Muse sites. I have used three of them for my own sites.
I have a client that I have a Muse temporary site ready to go live. When I go to Manage, it brings me to the Admin Console, where I can click on Push Site Live. However when I do that, it wants me to push the site live using one of my membership sites. I do not want to do this. I have the client's credit card info, and I want to sign them up for a webBasics plan. How do I get to that option?
Thanks!

Error in Migration Repository using Sql*Developer Migration Workbench

To migrate a MS access mdb database to Oracle using Sql*Developer Migration Workbench, I try to create first the the Migration Repository in SQL*Developer.
The repository is created, but under PACKAGES I could see that package MD_META has been compiled with errors.
PACKAGE BODY AO_PERSONAL.MD_META@DMCAPX (AO_PERSONAL):
Error(27,2): PL/SQL: SQL Statement ignored
Error(30,23): PL/SQL: ORA-00904: : ungültiger Bezeichner
Well, when I ignore this and continue with the next step of the migration process "Capture Microsoft Access Exported XML file" to create the Captured Model, I get the following error message:
ORA-04063: package body "AO_PERSONAL.MD_META" enthält Fehler ORA-06508: PL/SQL: aufgerufene Programmeinheit : "AO_PERSONAL.MD_META" konnte nicht gefunden werden ORA-06512: in "AO_PERSONAL.MD_PROJECTS_TRG", Zeile 3 ORA-04088: Fehler bei der Ausführung von Trigger 'AO_PERSONAL.MD_PROJECTS_TRG'
Target database RDBMS is Oracle Database 10g Enterprise Edition Release 10.2.0.3.0. So the proposal of note 427916.1 to create the Repository in a 10.2 RDBMS does not solve the problem.
I even tried to use the Quick Migrate feature in SQL*Developer, but got the same error message.

"inserted value too large for column"
Is there a LOGON trigger on the database or user ?
I'd be surprised at SQL Developer trying to insert data into anything on connect.
I'd suspect code being executed by the database, maybe using a MODULE or PROGRAM from v$session or USERENV / SYS_CONTEXT.
