AIX network option to help large data transfers:-

Just to let others know about this if they wish to review and test.
The no command on IBM AIX allows changes that improve large data transfers between AIX boxes and others. We improved our backups and interface transfers with these settings.

After copying files all day, it seems that by reformatting the drive but manually selecting a partition and setting it to GPT seemed to have solved the large volume transfers, whereas doing a "simple" erase alone may lead to issues...
Not sure why this is as the "simple" erase on an Intel Mac should basically be doing the same thing (GPT format).
Strange...

Large data transfers in early morning hours putting me over my data limit

I am getting large data transfers labeled Intranet Media Net from two different Iphones in my home. These transfers occur typically in the early morning hours when we are sleeping and when we should be connected to Wifi. ATT suggested that I turn off the option to send updates to Apple, which I did. However, the charges are still occuring. Last night a 35MB transfer has nearly put my daughter's phone over her 200 MB limit. ATT suggested that I turn off cellular data to eliminate these from occuring, but that seems silly. Plus, who is to say that they won't occur when I turn cellular on, in order to use data when I am outside of a Wifi area? Any help would be much appreciated. I don't know if this is an Apple issue or an ATT issue.

How do you get logs out of a TC anyway?
From the latest one you cannot.. no logs at all so that is the direction Apple is moving.. the black box.. well white box that you feed this into and get that out of.. but all the works inside are complete mystery.. that is the end point.. not quite there yet.
Logs from v5 utility or SNMP.. both still working on any of the earlier TC.
You can install v5 on Mountain Lion.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
Leave the package open on the desktop so you can see the file. AirportUtility56.pkg
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. If your Mac refuses to run the software, because it wasn’t downloaded from the Apple store, go to security in preferences and allow other software to work.. this is limitation of trade methinks. You can set back later if you like.
Now drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. in finder, open the new directory, drill down.. applications, utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall version 6 (now 6.3 if you updated) so don't try.. and you cannot or should not run them both at the same time.. although I have had no problems when doing so.
Give 7.6.3 firmware the heave ho.. and use 7.6.1 and if the TC is more than 18months old.. round about .. even a Gen4 you can go back to 7.5.2.. which seems more solid again.
As stated above.. by the time you get early Gen3.. they can have board faults. and earlier ones are especially not reliable with power supply faults.

Lose Network Connection w/AEBS 802.11n when transferring large data amounts

Hi,
I have a LaCie 500GB external hard drive that is connected to my AEBS 802.11n via a USB hub. Lately, when I am backing up my MacBook Pro to that drive, transferring 5GB or so of data, I notice that my MacBook Pro loses connection with the AEBS (i.e. the network goes down) right smack in the middle of the data transfer. I either have to reboot the MacBook Pro -- or -- unplug and replug the AEBS to reestablish connection.
I was just wondering if this sort of network connectivity loss is being experienced by other people doing large data transfers over the AEBS to an external drive?
Thanks.

I hate to be the one adding a "me too" post, but, me too!
When I try to open iPhoto (library stored on a USB drive attached to AEBSn) the AEBSn crashes, flashes orange once or twice and then restarts. Currently running firmware 7.2 because 7.2.1 wasn't allowing me to reconnect to AirDisks after MacBook went to sleep. If the drive is connected directly to my MacBook there is no problem.
If anyone, anywhere has any idea, I'd be very grateful!

Airport Extreme Intermittent Network Interruption when Downloading Large Amounts of Data.

I've had an Airport Extreme Base Station for about 2.5 years and have had no problems until the last 6 months. I have my iMac and a PC directly connected through ethernet and another PC connected wirelessly. I occasionally need to download very large data files that max out my download connection speed at about 2.5Mbs. During these downloads, my entire network loses connection to the internet intermittently for between 2 and 8 seconds with a separation between connection losses at around 20-30 seconds each. This includes the hard wired machines. I've tested a download with a direct connection to my cable modem without incident. The base station is causing the problem. I've attempted to reset the Base Station with good results after reset, but then the problem simply returns after a while. I've updated the firmware to latest version with no change.
Can anyone help me with the cause of the connection loss and a method of preventing it? THIS IS NOT A WIRELESS PROBLEM. I believe it has to do with the massive amount of data being handled. Any help would be appreciated.

Ok, did some more sniffing around and found this thread.
https://discussions.apple.com/thread/2508959?start=0&tstart=0
It seems that the AEBS has had a serious flaw for the last 6 years that Apple has been unable to address adequately. Here is a portion of the log file. It simply repeats the same log entries over and over.

Getting data transfered from old HD to new ones, leaving 2 slots filled . .

Hello,
*(Below is a thread I started in another forum, but, didn't get my final questions answered (see at bottom of this post in BOLD), and am hoping for further help and suggestions. I know there is a lot to read here, but, I think this information will help other novices, such as myself. Thanks!)*
I have 2 new HDs (each 1T) uninstalled, and I have my old HD (160 gigs) currently residing in one of the two slots in my G5. Any ideas on the best way/process to get the data transfered from the old HD to the new ones, leaving my two slots filled with the 2 new drives AND my data from the old HD transfered and intact, with a RAID0 setup?
OR, are there any other suggestions on a good setup with the 2 new HDs??
I'm open to suggestions.
I always back-up on external HDs, so, is their a need for me to worry about setting up a RAID0??
I'm doing video processing for DVD release.
Should I just max out the 2x1T gig HDs and not worry about a HD failure??
All Suggestions welcomed!!
Thanks, Jack
*FROM THE CUTTERMAN:*
You are limited with only 2 drive slots. In this scenario what usually works best is a small fast drive (eg Velocirapter or SSD) for OSX/Applications and a large drive for video files. It is not advisable to have the operating system running from a striped array.
Since you already have the drives, here is what you can do.
Install one new drive and format the partition you wish to use for OSX. You may not want to use the whole drive for OSX, so make 2 partitions. Be sure that it is GPT-formatted so it can boot.
Use CarbonCopy Cloner to copy your current OSX partition to the new one.
Set the startup disk as the new partition.
Remove the old drive and replace it with the second new one.
Reboot, and partition/format new drive.
*Hey Cutterman,*
Thanks for the advice. That sounds like a good set-up. I'll have to research the process of doing what you've advised, but, should work out ok:
A. Install one new drive and format the partition you wish to use for OSX. You may not want to use the whole drive for OSX, so make 2 partitions:
1. Partitions are done under Disc Utilities correct? Never done it before; will take a look.
B. Be sure that it is GPT-formatted so it can boot.
2. GPT is also done under Disc Utilities, correct? Here I start to get a bit confused, as I've formatted Extended Journal, SO, the partition with the OSX & Applications is formatted GPT, and the rest of the HD is formatted as Extended Journal?
C. Use CarbonCopy Cloner to copy your current OSX partition to the new one.
3. So, I partition the first new HD and use Carbon Copy Cloner (also under Disc Utilities) to copy the OSX & Applications from my original HD to the first new HD, correct?
D. Set the startup disk as the new partition.
4. This will be an option when I setup the partition???
E. Remove the old drive and replace it with the second new one.
F. Reboot, and partition/format new drive.
5. QUESTION: So, you recommend not striping the HDs: If I do a RAID 1, which sets up a mirror of the HDs, and since the first new HD is partitioned with the OSX & Applications, AND is set up as the Startup Disk, then the second new HD will also mirror that?? Another QUESTION: Even if the second new HD does not mirror the OSX & Applications, the second HD will only mirror the space/partition not utilized by the OSX & Applications partition, correct?
Thanks for your help!!
Jack
*FROM THE CUTTERMAN:*
OK I will try to answer your questions. To begin, if you want to mirror the 2 drives then you will need to boot from the SL install DVD or an external (USB/firewire) drive to set it up. IMO for your purposes it is too much hassle and a waste of HD space.
1) Yes partitions are created in Disk Utility
2) Yes, you choose a volume Scheme (ie number of partitions) and size them by dragging the separator bar. Then select the planned boot partition and click Options..., then choose GPT. I think it is usually the default but check and make sure. Extended journaled is the usual format.
3) You need to download Carbon Copy. It is a free tool that will copy the entire image of your current system partition to the new one and make it bootable. Consider making a donation as it is a very useful and frequently updated utility. It is fairly intuitive to use. You can also use the restore feature in Disk Utility but I have had more experience with Carbon Copy.
4) Once the copy process is finished the new boot partition will show up under the startup disk selections (this tool is in System Preferences).
*FROM 666Sheep:*
If may i correct one thing: OP, don't choose GPT (GUID Partition Table). You got PPC Mac (G5), so valid partition type for you is Apple Partition Map (APM).
GPT is for Intel Macs and you will not able to boot from this kind of partition.
*FROM THE CUTTERMAN:*
Thanks for the correction- my bad. No familiarity with non-Intel Macs.

*Hi All,*
*Since this process will come to a head on Tuesday/Wednesday, and I hope to be successful in transferring Old HD data to new HD/s.*
*A: I'm still a little foggy here, as I thought I'd set up the 2 new T-gig HDs so that if one of them failed, I'd still have the data backed up on the other HD; more ideas concerning this would be reassuring:*
*WHAT DOES "IMO" mean?*
*(IMO for your purposes it is too much hassle and a waste of HD space.)*
*As I understand the points made: After I partition the first new HD, and Carbon Copy data from old HD, I then install second new HD, and this will just act as an overflow from the first partitioned HD, correct? Because, if set up a Raid1/Mirror, the OSX partitioned portion of the first new HD will not copy to the second new HD, and that space on the second new HD will be wasted, correct?*
*Also: I have to set up RAID1 (if I do not set up RAID0), correct?*
*RAID 1*
*From WIKI: RAID 1 mirrors the contents of the disks, making a form of 1:1 ratio real time mirroring. The contents of each disk in the array are identical to that of every other disk in the array. A RAID 1 array requires a minimum of two drives.*
*Carbon Copy is a free tool that will copy the entire image of your current system partition to the new one and make it bootable.*
*1. Is my old HD partitioned? Is that done automatically by MAC prior to PC purchase?*
*2. Do I Carbon Copy the whole old HD or just parts? (eg. OSX, Photo Shop, After Effects, Various Files)*
*3. I read that it is necessary to DEACTIVATE Photo Shop (I have CS3) prior to doing Carbon Copy. Is that correct? If so, does this also apply to other Adobe applications? Such as After Affects, Illustrator??*
*Thanks to all for the help!!*

Confusing Information:
A1: You also want to make sure the drive you are backing up to is formatted Mac HFS Extended (HFS+) if using Mac OS 8.1 or above.
A2: On PowerPC Macs, your clone should be partitioned as Apple Partition Map.
*Q? I thought the new HD (1T) should be formatted in Extended Journaled?*
B: Also disable Spotlight (in 10.4 only) on your destination drive using Apple menu -> System Preferences -> Spotlight -> Privacy to add the destination drive to the pane.
*Q? I'm using 10.4.11, so, I should follow these instructions?*
C: If possible, boot into safe mode to perform the backup (holding the SHIFT key at startup). In addition, you can clone while logged into another administrative user that you don't use at all to avoid further complications of changes which may be happening to your regular user (though don't use Fast User Switching to get into that other user, since that other user is still active when fast user switching is used). Otherwise you are going to be running a backup on a live system which could have changes happening while you are attempting to backup. These may yield an imperfect clone, with uncertain success at recovery. It may be possible that your clone will have its own hardware issues, so make at least two copies.

Hyper-V 2012 VMs freeze on large file transfers

I have a small non-clustered Hyper-V Server setup as follows:
HP ML350p Gen8 Server, 6 core E5-2620 CPU and 32GB Memory running Server 2012 (full GUI) with the Hyper-V role enabled.
The Server has 8 disks, 1 pair of RAID1 15k disks for the Server 2012/Hyper-V OS, and 3 pairs of RAID1 10K disks for 3 VMs (ie each VM has its own pair of RAID 1 disks). The NICs in the Server are 4 x gigabit ports on an internal
331i card and 4 x gigabit on an external 331T card. The Hyper-V Server is not running anything other than the Hyper-V role, the LogMeIn client and Symantec SEP SBE 2013 (with recommended Hyper-V exclusions in place) and
the VMs are a Domain Controller, a SQL Server and a File Server. Currently all VMs have their own single 1GB NIC connection on the 331T card, all VMs have a single IP address and are on the same subnet, no VLANs are used.
I have applied what hot fixes I can from a TechNet article that recommended how to setup Hyper-V.
Initially I had a problem with NIC latency during pings, which we traced to being due to the ML350 Gen8 Server's NICs not liking VMQ enabled. When disabled all looked fine, but we had not yet tried to use the Server in production.
Recently (getting ready to go in to Production use) we have noticed when transferring a 3.5GB ISO of SQL media to a file share on one of the VMs from a desktop PC that this causes the VM to lock up. The file copy will still complete but the screen freezes
when accessed via Hyper-V manager or remotely via LogMeIn and sometimes the LogMeIn remote session is dropped too. If you cancel the file copy the console is immediately responsive again.
Since we built the server a while back, HP had subsequently released an updated NIC driver which we installed and it seems to have fixed the VMQ issue, but with or without VMQ enabled we seem to experience the lockups as soon as we transfer medium to large
size files. The issues were there before and after we upgraded the NIC driver, we were hoping it would address the issue, but it didn't. These servers are very lightly loaded and the problem occurs even on the SQL Server VM with the SQL service disabled
(ie the server has hardly anything running at all and the console freezes with a single user performing a single file copy).
We have 3 VMs on the Server, 2 are running Server 2012 and seem to be more affected, the VM running Server 2008 R2 seems less affected. VM to VM transfers seem to be working better (ie slows down slightly but no lock ups), it is only during external network
transfers. Also the faster the transfer speed is, the worse the issue becomes. If the file is copied to a share on the Hyper-V Host the issue does not occur, only transfers to the VMs.
Does anyone have any idea what might be the issue here? I saw a hotfix for 2008 for a similar issue but can't seem to find anything for Server 2012.

I think we have tried almost every combination of disabling Large Send Offload, TCP offload, IP SEC Offloading, VMQ and Receive Side Scaling possible - in the various places there are - although I will be quite honest - as there are 3 places to do this
for each Server (the related physical and virtual NICs on the HV Server, and also the NIC in the VM) it is possible we may have missed an iteration...
During our testing we have noticed that the symptoms of the problem gets worse the higher the transfer speed is. For example if you transfer to the VM from a desktop with a 100Mbs NIC, there will be subtle lag and a transfer speed of say 10 or so KBs ,
if you use a device with a 1Gbs NIC, you on average achieve 50-70 KBs transfer speeds and the higher the number, the worse the GUI / Server locks up (although the transfer completes just fine).
We also tried throttling the bandwidth via the 2012 GUI - to see if that helped, but none of the changes we made seemed to work, and we did not have time to try the powershell way of doing this.
We did replace one of the VM's NIC with a legacy one as part of our testing today, and now data transfers to the VM from a PC with a 1Gbs NIC run slower at around 30-35 KBs and the are no noticeable GUI freezes, although during the large transfer
it looks like 1 in every 30-40 packets is dropped in a continual ping that runs during the transfer period.
We have done a lot of cable replacing today (out of diligence) but there seems to be no noticeable issue. We also tried and older NC380T dual port NIC we had available and used the standard driver Windows offered instead of an HP one, but the problem
was identical no matter which NIC we used.

TimeCapsule (and AirPort extreme too) hangs on large file transfers

Greetings,
I got a following problem. I had install AirPort connected to my router with copper and extend network with TimeCapsule. TimeCapsule have two USB drives attached, AirPort - one USB. When I am transferring a large file, in a magnitude 2-3Gb or multiple simultaneous transfers of smaller files to/from those USB drives, depending on which drive I am using the AirPort or TimeCapsule get crashed. For plain user it is looks like as of sudden, data transfer stops, led in a front keeps green, and I can not reconnect to the drives. If I powercycle TC or AES everything get back to normal. Are there anyone else experiencing the same issues and if yes, what would be solution ?
Thank you.

Purchased Content and Data Transfers

I had a few questions regarding purchased content (i.e. apps, music, movies) and data transfers:
1. Can you re-download purchased apps for free or do you have to purchase them again?
2. Can you re-download purchased movies and music if the data is lost or do you have to purchase them again?
3. I noticed every time you download a movie it prompts you to backup the data with discs. I practically never use discs and most of the time, I have a large amount of purchased data that simply will not fit on DVD-Rs. Is it possible to backup data via external hard-drives? Is there an export option in iTunes to do this or do you have to go into the physical path which it's located?
4. Can you sync purchased content with multiple devices? For instance, I have a 32GB iTouch and an iPhone, would I be able to sync the same data for both of these devices or am I restricted to one?
5. How many computers can you have data synced with? For instance, I have five computers and a soon-to-be MacBook. How many computers can I have the same data synced up to?
I tried looking around for this information, but didn't have much luck finding it. Apple doesn't seem to clearly define these parameters unless there is a link one of you might have that discusses these issues. Any assistance would be greatly appreciated.

Redownload for free, assuming still available in the store.
2. Can you re-download purchased movies and music if the data is lost or do you have to purchase them again?
You are not entitled to a repeat download of any media item. Sometimes unfortunate users are granted a one-time only repeat download if they ask nicely but don't count on it.

Yes, you can backup to external drives or network shares however iTunes has no system for managing this. You just need to copy the files from their source folders, either manually or....
*Fast backup for iTunes library (Windows Only)*
Grab SyncToy 2.1, a free tool from MS. This can be used to copy your entire iTunes library (& other important data folders) onto another hard drive or network share. You can then use SyncToy periodically to synchronise or echo your library to the backup. A preview will show which files need to be updated giving you a chance to spot unexpected changes and during the run only the new or updated files will be copied saving lots of time. And if your media is all organised below the main iTunes folder then you should also be able to open the backup library on any system running the same version of iTunes.
4. Can you sync purchased content with multiple devices? For instance, I have a 32GB iTouch and an iPhone, would I be able to sync the same data for both of these devices or am I restricted to one?
You can sync the content to as many iPods/iPhones/iPads as you like. Each device can hold protected content from up to five different accounts at any one time.
5. How many computers can you have data synced with? For instance, I have five computers and a soon-to-be MacBook. How many computers can I have the same data synced up to?
You can authorise protected content on up to five different computer systems at any one time. Virtual machines count as separate systems as do computers with reformatted drives or, perhaps, certain hardware changes. Ideally you should deauthorise a computer before any major upgrade. If you are no longer able to access one of your systems but need to release the authorisation then, if you have five active authorisations you can deauthorise all of them together, however you may not then repeat this preocess for 12 months.
Protected content can only be transfered to a device when the computer is authorised. Devices may be manually managed from a number of computers but may only be automatically synced with one. Syncing is a one way process as far as media is concerned, library to device, but certain metadata such as play count and rating flows in both direction. With manual managment such metadata is not copied.
I tried looking around for this information, but didn't have much luck finding it. Apple doesn't seem to clearly define these parameters unless there is a link one of you might have that discusses these issues. Any assistance would be greatly appreciated.
No problem, that's what these forums are for... The information is probably spread around a number of support articles but I don't have the individual links to hand. Feel free to ask if you want more details though.

Network based and a-gps, data use tests

i was trying to find this kind of info, but only found others asking.
i hope this is useful info for others, especially while roaming.
skip to the bottom for conclusion,
this is the process i took:
i called nokia tech support,
their phone support his horrible,
the people on the phone don't actually know anything, and have to look up everything you ask them.
they were the worst.
i emailed nokia tech support.
my message was:
"i would like to know the difference between assisted gps positioning, and network based positioning. these are 2 of the 4 options on my nokia e66 for positioning methods. i would like to know if network based positioning uses internet data from my service provider to obtain my gps position. i am especially concerned with this function while i'm roaming internationally, as i do not want to be charged for roaming data use."
in about half hour they responded w/ an answer, and then 45 min after that someone else responded w/ an answer.
the first response, minus the hello's etc. was:
"In response to your email, Assisted GPS and Network Based positioning methods generate costs related to data traffic so you will be charged for data use. Only "normal" GPS and Bluetooth GPS do not generate additional costs related to data traffic.
Normal GPS is quite slow and does not work indoors. Therefore, it is recommended to enable at least A-GPS to get a faster position outdoors.
Network based and Wi-Fi positioning also allow you to update your position inside buildings, but they cannot be used for navigation."
the 2nd response was:
"In response to your inquiry, the difference between Assisted GPS positioning (A-GPS) and Network based positioning is that, A-GPS uses satellites while Network based positioning is based on information of your cellular network environment. It allows you to update your position inside buildings, but they cannot be used for navigation. Both positioning methods generate costs related to data traffic (unless you have configured the device to use Wi-Fi connection to make the internet connection). The cost may vary while you are on roaming. Kindly contact the service provider for information about data transmission costs."
i can also respond w/ more questions, but instead did some tests, starting with sitting home, indoors, and eventualy moving to a window w/ lots of sky.
test 1:
i enabled:
integrated gps
network based
assisted gps
opened maps,
set maps to be offline,
set default internet access point to my home wlan network,
closed maps,
cleared all counters and the log on the phone's communication log.
opened maps
there is a pink circle around the area i may be in,
the icon that would show gps satellite strength, changes to show the cell phone antenna icon.
but the packet data counter is sending/receiving a total of around 3-8kb immediately, and over the course of time, it keeps adding up, every 1-2 minutes, and it is shown as packet data to/from the access point "at&t internet"
over the course of ten minutes, it's been about 43kb.
and i can tell on the phone's home screen that the packet data connection becomes active when it does.
the maps kb indicator still says 0.0kb, with a line through the double arrow packet data symbol.
test 2:
now i exited maps,
cleared the counters and logs
i turned off a-gps.
enabled only integrated gps and network based.
i open maps,
the same thing is happening as with the assisted gps on, except i connected to my home wlan once, in the middle of connecting to at&t internet 10 or so times.
everything else is happening the same.
test 3:
i exited maps,
cleared the counters and logs.
enabled only integrated gps.
i open maps, and there is no evidence of packet data connection, or wlan connection.
nothing is showing up in the logs or packet counters, and there is no pink circle around where i may be.
if i set maps to go online, w/ my wlan as the access point, or at&t internet, their respective icons show up on maps, as well as the phone's home screen.
the phone's log show respective connections are made but w/ 0.0kb, and the phone's packet counter, as well as the maps kb usage, say 0.0kb.
test 4:
set maps to offline, w/ my wlan as access point.
exited maps,
turned phone off for a bit to test gps from cold start.
turned on phone,
cleared counters/logs,
enabled only assisted gps and integrated gps.
open maps, there's no pink circle around where i may be, just the red dot of where it thought i last was.
there's about 4-5kb of data transfer,
then i bring the phone to the window where there's a lot of clear sky, and my location is found pretty fast.
i know that w/o assisted gps, w/ only integrated gps, it takes a while to get the gps signals.
i went back and forth to/from the window, and there was packet data use again only once more, not continuously like w/ network based positioning.
so to conclude my tests,
setting the maps to be offline, still uses a-gps and network based positioning.
network based uses a more data, continuously,
which is the opposite of what i thought, i thought a-gps would use more, so i was using network based on and a-gps off while in canada. whoops.
using assisted gps uses about 5-10kb, which, when roaming, according to at&t, they charge 1.95cents/kb.
might be worthwhile for getting a quick gps signal, nothing worse than waiting forever for it to connect.
the only way to be completely clear of data use is disable network based and assisted gps, or set the phone to offline mode.

A-GPS: This uses information from cell network to get a rough idea of where you are. It then uses this information to figure out which satellites to look for. Result is a faster satellite lock. So A-GPS uses a few kB of data to get an initial position, but navigation is done using GPS satellites, which does not require ANY data connection.
Network based: This uses information from the cell network to plot the current position when GPS satellite signal is not available, ie indoors, in a tunnel, etc. Position info derived from the cell network is not as accurate as that from GPS satellites, but serves as a stopgap until GPS signal can be re-acquired. Network based positioning used your data connection EACH TIME the satellite lock is lost. So the amount of data used is dependent on the quality of access you have to the GPS satellites. If you don't lose the connection to the GPS satellites, then you won't use any data.
The ‘offline’ option within the Nokia Maps app only refers to street, POI, etc searches, NOT to A-GPS, Network based positioning or to connecting with the GPS satellites.
If you want to navigate without using ANY data connection, set A-GPS off AND set Network based positioning off AND set the Internet option in Nokia Maps to Offline. Do this and you will not use any of your data connection allowance when navigating. There is no need to put the phone into flight mode.

Is there a Java utility class to help with data management in a desktop UI?

Is there a Java utility class to help with data management in a desktop UI?
I am writing a UI to configure a network device that will be connected to the serial port of the computer while it is being configured. There is no web server or database for my application. The UI has a large number of fields (50+) spread across 16 tabs. I will write the UI in Java FX. It should run inside the browser when launched, and issue commands to the network device through the serial port. A UI has several input fields spread across tabs and one single Submit button. If a field is edited, and the submit button clicked, it issues a command and sends the new datum to the device, retrieves current value and any errors. so if input field has bad data, it is indicated for example, the field has a red border.
Is there a standard design pattern or Java utility class to accomplish the frequently encountered, 'generic' parts of this scenario? lazy loading, submitting only what fields changed, displaying what fields have errors etc. (I dont want to reinvent the wheel if it is already there). Otherwise I can write such a class and share it back here if it is useful.
someone recommended JGoodies Bindings for Swing - will this work well and in FX?

Many thanks for the reply.
In the servlet create an Arraylist and in th efor
loop put the insances of the csqabean in this
ArrayList. Exit the for loop and then add the
ArrayList as an attribute to the session.I am making the use of Vector and did the same thing as u mentioned.I am using scriplets...
>
In the jsp retrieve the array list from the session
and in a for loop step through the ArrayList
retrieving each CourseSectionQABean and displaying.
You can do this in a scriptlet but should also check
out the jstl tags.I am able to remove this problem.Thanks again for the suggestion.

Data Model best Practices for Large Data Models

We are currently rolling out Hyperion IR 11.1.x and are trying to establish best practces for BQYs and how to display these models to our end users.
So far, we have created an OCE file that limits the selectable tables to only those that are within the model.
Then, we created a BQY that brings in the tables to a data model, created metatopics for the main tables and integrated the descriptions via lookups in the meta topics.
This seems to be ok, however, anytime I try to add items to a query, as soon as i add columns from different tables, the app freezes up, hogs a bunch of memory and then closes itself.
Obviously, this isnt' acceptable to be given to our end users like this, so i'm asking for suggestions.
Are there settings I can change to get around this memory sucking issue? Do I need to use a smaller model?
and in general, how are you all deploying this tool to your users? Our users are accustomed to a pre built data model so they can just click and add the fields they want and hit submit. How do I get close to that ideal with this tool?
thanks for any help/advice.

I answered my own question. in the case of the large data model, the tool by default was attempting to calculate every possible join path to get from Table A to Table B (even though there is a direct join between them).
in the data model options, I changed the join setting to use the join path with the least number of topics. This skipped the extraneous steps and allowed me to proceed as normal.
hope this helps anyone else who may bump into this issue.

Out of the blue, my AppleTV went to a screen that had two icons, Computers and Settings. Why won't it go the the usual TV screen with viewing options? Help!

Out of the blue, my AppleTV went to a screen that had two icons, Computers and Settings. Why won't it go the the usual TV screen with viewing options? Help!

Here's what finally worked for me with Apple TV 3rd generation. Out of the box, when setup with wi-fi, it breezed through without any issue. As soon as I powered down and connected it to another tv (same wi-fi network), it got stuck at setting date/time. The remote would help in getting out of it, but the home would only have "Computers" and "Settings" and pretty much useless except for AirPlay. Here's what I did to resolve this:
1. On your main router, temporarily disable the firewall or set it to the lowest setting allowable (a reboot of the router maybe required).
2. Restart apple tv via the "restart" option in the "General" option in the main settings menu.
3. It should breeze through and not show the "Setting date/time" screen.
4. Once it loads up properly, turn on your fire wall as before (a reboot of the router maybe required).
I think it worked for me out of the box, but auto-update to the latest software introduced this bug. So, everytime apple tv tries to synch with the time server, this issue will come back. To disable this, I turned off the "auto time synch" option in Settings -> General.
I am fairly confident that I'd be able to use steps 1 through 4 anytime this recurs. Possible scenarios causing recurrence of this issue:
1. Unplugging the power to apple tv or power failures.
2. OS updates.
3. Restoring apple tv using "Restore" or via micro-usb and iTunes to the lastest OS.
Hope this helps. Please post if this works for you.
