Does JRockit perform any optimizations on URL connections to the same JVM?

Hi
I am wondering if JRockit would understand a local connection request, such as a SOAP call to a service hosted on the same JVM (localhost), and perform this in a manner without the overhead of a full connection. i.e. is there a difference in calling a service as http://localhost/service vs http://remote/service if the end service is hosted on the same JVM?
thanks
asankha

I wrote a simple Java program to listen on a socket and when i used a Java client program (ie. in a separate JVM) to call this, I saw that tcpdump does not see packets if this communication occurs through on the same host - but it sees the packets when invoked from a different host. The same was visible in directly TELNET'ing to the port. This was seen in both Linux and Windows.
Hence I assume, this will hold true always, and local SOAP calls will not incur unwanted overhead (http/s)
Would appreciate any feedback if anyone thinks this assumption is wrong..
thanks

Hi, my ipod (2nd gen) won't connect to the internet via Safari or through apps but my email does work. Any ideas without needing to reset the ipod?

- Have you tried when connected to other networks? Maybe the router is blocking the ports used by Safari and the other apps.
- What kind of network are you using? a personel or bussines?

Re: Everytime I close Itunes it loads back up

I have 2 Macs, connected to the same Wifi network. But sometimes, the shared computers does not appear on the left hand menu of the toolbar for me to access shared folders between the computers. Am I doing something wrong?

I recently bought a MacBook Air for work. Whilst at home, both my Macbooks are connected to the same Wifi network. Sometimes, the 2 Macbooks are connected and I can access the shared folders, which is great. However, every now and again, the connection seems to be lost. Is there something I need to set up so that every time both Macbooks are switched on and connected to my Wifi, it will automatically be linked?
Any help is much appreciated!

I have found with AppleTV that it is the IPV6 on the computer you want to access is the problem. The issue is that Homegroup on Win 7 or Win 8 requires IPV6 to work, but AppleTV won't work with IPV6. (So maybe double check you have IPV6 turned off)
So you have to make a choice - Homegroup or AppleTV.... but you can't have both, until Apple brings ATV up to date. (crazy that it does not recognise IPV6 - c'mon Apple!)
You can set up sharing individually in Win 7 or 8 and have the ATV access files that way.
Having said that, there is always the exception.. I have an old HP home server running Win8 and it services ATV - but is part of the Homegroup... have no idea why it works on both, but no other machine on the home network will talk to both ATV and Homegroup at the same time!

1) You asked "Does she need to reconnect to that itunes/computer and if so what do we need to do to remove this folder of pics from her ipod?" Yes, you have to connect the iPod to that computer and go to the Photos pane for the iPod in iTunes and uncheck sync photos and the click on synce/apply. In the future do not check sync photos.

2)
Create a NEW account for using these instructions. Make sure you follow the instructions. Many do not and if you do not you will not get the None option. You must use an email address that you have not used with Apple before.
Creating an iTunes Store, App Store, iBookstore, and Mac App Store account without a credit card
Then on the iPod go to

- Settings>iCloud and sign out and sign in with hers
Contnue to use the commpn ID/account for Settings>iTunes and App stores.

HT5569 iPhone WiFi issue. I enter a password, click join, and get a message back that it is the incorrect password. I have several computers and two other iPhones connected using the same password. Any clues?

Hey there Gordo456,
It sounds like you are not able to join your Wi-Fi network with the correct password on 1 out of many devices. I recommend the troubleshooting from the article named:
iOS: Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/TS1398
Restart your iOS device.
Update your device to the latest version of software.
Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
If that troubleshooting does not resolve the issue, I would next try these steps from further down the article:
Unable to connect to a Wi-Fi network
Verify that you're attempting to connect to your desired Wi-Fi network.
Make sure you're entering your Wi-Fi password correctly. Passwords may be case sensitive and may contain numbers or special characters.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
previously connected Wi-Fi networks and passwords
recently used Bluetooth accessories
VPN and APN settings.
Thank you for using Apple Support Communities.
Regards,
Sterling

Does your device require being connected to the same wifi network as your computer to be able to backup onto it?

Does your device require being connected to the same wifi network to backup onto your computer?
I know this may sound a silly question but I am a complete noivce with all things iPhone and computer based. Basically, I just wondered, if my phone is connected to one wifi network (as in when am away from home), will it be able to download my content onto my computer which is on another wifi network?

Thank you.
'Of course, you could just turn on iCloud backups, which will back up to iCloud at night so long as the phone is connected to power and a WiFi network'
IS this also the case for iCloud backup? As in, the device and computer must be connected via the same wifi network to perform the backup?

Does it cost any money when you imessage outside the United States?

Does it cost any money when you imessage outside the United States?

It shouldn't if it is truely an iMessage and you are using wi-fi, such as your home LAN.
There is a difference in cellular SMS text messages and iMessages. The other person must have an iOS device and you must both have an internet connection. The conversation will appear in blue.

I have 2 iPhones - one for personal use and one for work. They are currently connected with the same Apple ID. I would like to separate the two accounts. Does anybody know how to do this?

Just create a new AppleID for your work.
As Allan suggested, items purchased on one iTunes account cannot be moved to the other account.
However, you can put items purchased on on account onto the other iPhone.

I have an iphone and an ipad (which are connected by the same apple id) i broke the phone and sold it but i didnt get to factory reset it because it was broken, is there any way for me to wipe my iphone from my ipad?

i have an iphone and an ipad (which are connected by the same apple id) i broke the phone and sold it but i didnt get to factory reset it because it was broken, is there any way for me to wipe my iphone from my ipad?

Try this:
Open the "Find my iPhone" app on your iPad, fill in your AppleID and password at the start up screen, and you should see a list of all your devices and their current location, if connected to a Wi-Fi or mobile data network. Devices not connected will be shown as "offline". But you can still trap on the icon and hit "erase iPhone" in the right hand window.
If your iPhone is not listed, you did not activate this feature during the setup of the phone and it can't be erased remotely.
If the phone is listed, even as offline, tap on "erase" to send the erase command. The next time your device will be connected to any kind of network, the content will be erased.

My family shares one apple id. Is there any way to make an apple id for each member of my family and have it all connected to the same credit card and have the same previous downloads open to download by signing in to each members personal apple id?

My family shares one apple id. Is there any way to make an apple id for each member of my family and have it all connected to the same credit card and have the same previous downloads open to download by signing in to each members personal apple id?

Hi cindy,
If you all have individual Apple IDs, then you would be able to dowload music from a shared iTunes library on a computer, but you would not be able to sign on each individual ID on an iOS device in order to download music purchased under the original Apple ID without a 90-day waiting period between sign-ons.
Here's what I mean:
If you were to sign on a new Apple ID on, say, an iPhone, and then were to purchase and download some music from iTunes, then you would have to wait 90 days before you could sign on the old Apple ID to that iPhone in order to download previously purchased material (and vice versa).
However, if all of the music purchased by that origjnal Apple ID is in an iTunes library on a shared computer, then you can hook up the device and selectively sync any music in that library to the device. You can also sign on any of the Apple IDs to that shared iTunes library and purchase music to be added to the library.
You would need to authorize the computer for each of the new Apple IDs.
Each of the Apple IDs would also be able to download that music purchased either by syncing to the iTunes library on the computer or by downloading it OTA on the device.
So, each Apple ID can download music, movies, etc. purchased with that Apple ID OTA to the device. Also each Apple ID can sync any music, movies, etc. that are in the iTunes library on the computer regardless of who purchased them.
The only other thing you would need to remember is that if an App needed to be updated, then the original Apple ID that was used to purchase that App would come up, and the password that goes with that Apple ID would be required to do the update.
Hope that helps,
GB

HT4437 I bought a brand new iPad 3 and an Apple TV, both connected to the same wpa protected wifi network from home. It worked for a day, but when I woke up, the Apple TV couldn't be found anymore by neither iPad, MacBook or iPhone. Any clue? Thanks!

Thanks for the swift reply, I have been looking online and a loose plug seems to be somewhat of an issue with many, I hope mine is actually a problem and not what others are experiencing. It's taken me this long to even reach out for the simple fact I HATE being a complainer but this is just horrible.
Do you have an iPad 3 as well? And is yours not experiencing any issues close to mine?
Thanks again!

Troubleshoot the network as that is likely what is causing the issue.
Also, temporarily disable the firewall on the Mac and disable IPV6 on the computer.

How do I get the internet connection back onto ipad even though it connects to Wifi successfully and I have checked on my iPhone which does connect via the same wifi and to the internet?

Your router may not have given your iPod a valid IP address. Go to Settings > Wifi > your network name and touch the ">" to the right to see the network details. If the IP address shown starts with 169 or is blank then your router didn't provide an IP address and you won't be able to access the Internet.
Sometimes the fix can be as simple as restarting your router (remove power for 30 seconds and restart). Next, reset network settings on your iPod (Settings > General > Reset > Reset network settings) and then attempt to connect. In other cases it might be necessary to update the router's firmware with the latest from the manufacturer's support web pages.
If you need more help please give more details on your network, i.e., your router make/model, the wifi security being used (WEP, WPA, WPA2), etc.

How to find whether any disk arry is connected in the system

Hi Guys,
Please help me regarding Disk Array.
1) What command(s) should I use to check whether any disk array is connected in the server or not.
2) Please share the method for,
For single server system (A single sun server is connected with exernal disk array).
For Cluster server system (Two servers are connected as a sun cluster and Disk array is connected to the cluster as resource).
3) If the disk array is from SUN or from other vendor, how can i know that?
4) How to find how many disks are available in the Disk array?
Thanks

Wow... I got a reply from nik !!!
Thanks for your reply..
*1) I have a confussion that format command only report the local disks not external disks(Disk array). Is that correct?*
2) We have a cluster server V890+V890 + Disk-Array(Sun StorageTek). The format output is below.
