Heavy IO maintenance while having alwaysOn

I have some maintenance which generate a lot of IO (i.e. compress big tables, apply partition on a big table, reindex on very big tables etc.),
My DBs are synchronize to the DR site over a network line with low bandwidth.
I have to keep both sites synchronized all the time.
How can I do such maintenance if while doing the above activities it generates a lot of IO which can not be handled by the network?

Hi,
This look bit generic question and a lot can be done depending on the environment and knowing the environment.
Is AlwaysOn configured asynchronous or synchronous commit?
Is there any I/O error or slowness issue reported @ application end?
Check this link and especially comments section with lot of discussion on this point,

Yeah, there’s lots you can tweak — you can leave a few minutes between commands so that things have time to catch up, do partition level rebuilds (offline, only if using partitioning), and timebox the whole operation so that you only do a smaller amount
of work. And of course limiting what you’re targeting (by level of fragmentation, purpose) helps. And you could potentially reorganize for a while and then manually stop the command in some instances.

While having a perfectly running iTunes and all programs associated, I was notified of the iTunes 10.4 upgrade. After following typical directions, I have had nothing but trouble. First “iTunesHelper was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 5)” occurred. Following directions found at https://discussions.apple.com/message/15087646#15087646, I now get the following “iTunes.exe - System Error The program can't start because AVFoundationCF.dll is still missing from your computer. Try reinstalling the program to fix this problem.”, Along with “iTunesHelper was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 126)” I am running Win 7 Ultimate 64 bit on HP TouchSmart tx2-1275dx. I was one week away from buying an iPad but not if this is what I have to deal with. Please help

I actually managed to resolve this on my own by downloading iTunes from the Apple website and reinstalling iTunes that way. Here's the link: http://www.apple.com/itunes/download/ That should fix your problem. Good luck!

My phone does not show contact names for country and area code while having in coming calls. Although, I have endorsed the name with numbers. How do I the problem. My one is a iphone 3s device with updated os. Please text to help

My iphone does not recognize saved contact number while having incoming calls due to country and area code as auto prefix. How do i fix the problem. How do i ensure that the phone recognize calls with and without the country and area code. Please text to help.

1) Open the Phone and dial *228. This is a Verizon over-the-air programming number.
2) When the system answer press 1 for "Program or activate your phone"
3) Wait for the call to disconnect. You should get a prompt stating something like, "Settings updated."
4) Open the Task Manager and kill the Phone, Message, and Contacts Applications
5) Wait a few minutes (I waited 3 just to be extra safe)
6) Open the Message App to verify the fix

Is it possible to create a Windows 7 Partition via Bootcamp while having an internal RAID 0 Setup ?

Is it possible to create a Windows 7 Partition via Bootcamp while having an internal RAID 0 Setup ?

Yes, just not on the RAID. Boot Camp Assistant will only partition a single drive containing OS X. You cannot partition a RAID array.

Installing a Dialog instance on a 2008 server while having the CI on 2000

Hi all,
Can we do such a thing? Install the Dialog Instance on a 2008 server while having the CI on 2000?
Thanks!
Samer

Yes you can do it.
What you need to keep in mind that both system should be in network and /sapmnt should be mounted into DI server.
We have tested it into 2 different Linux version yesterday.

Illustrator CS6 hangs saving files to local HD while having multiple server share points mounted

Mac OS 10.6
Illustrator CS6
Illustrator CS6 hangs (spinning beach ball) when saving files to the computer's local HD while having multiple server share points mounted.
I am NOT opening or saving the file to or from a server.
The server is mounted so that I can move my saved file to it once complete.
Unmounting the servers fixes the problem and Illustrator CS6 returns to being normal (not causing a spinning beach ball).
This is repeatable, not intermitent.

We were having similar issues working over a network. I believe it's a Mac OS 10.6 issue, something to do with the Mac finder searching for file dates or metadata on the servers. From what I understand, this has been fixed in OS 10.7. We can't yet move to 10.7 and after trying many possible fixes, found that a Mac finder alternative, Path Finder, fixed most server delays. It's not free, but you can give it a 30 day trial to see if it fixes your issue. Here is a link to discussions about other suggested fixes:

Restoring rman backup to sysdate-n while having latest full backup

is it possible to restore n-5 days database state while having latest full rman backup (n) ???

Hi,
You need the archivelog and a backup prior to the date you want to restore.
So:
You cannot return back BEFORE the date of a backup.
You can go back to the date of a backup if you have no archivelog (or archivelog backup).
You can go back to the date of a backup and anytime AFTER if you have the archivelog (or archivelog backup).
You can go prior (depending of the retention) if you use flashback (flashback log).

i was lost my ipod two days ago is there a way that someone might be able to go throught my stuff while having a passwrod on it? please help me

If it is passcode protected, then it is very unlikely that anyone woul both have the knowledge and take the time to try and break the code.
They would very likely restore teh ipod and use it as their own.

Can you take pictures while having your flash light on, instead of using your camera's flash?

Hello I have a 5s and want to know if you can take pictures while having your flash light on, instead of using your camera's flash? Having a constant light seems like a better way to take pictures. If this is possible how? Do I need certain apps? or just adjust settings? Any help would be much appreciated. Thanks Pat

The Flashlight uses the camera flash as its source of light. You are in fact using the flahslight when you take a picture with flash because they use the same light source.
The Flash is timed to light the picture when the camera snaps the photo.

Trial expired while having active cloud membership

Hello,
I suddenly get the notification that my software trials have expired. This while I have an active cloud membership, so this doesn't make sense. Haven't been using the trials for over 8 months.
Bottomline, I can't start my programs and can't get any work done.
Please advise,
With kind regards,
Tom Paulussen

Hi Dave,
Is it possible that upon deactivating one software program (Illustrator) all the other ones are also deactivated?
I just bought a new iMac and want to install my software on this computer. because I have only 1 license, I need to deactivate them on my old iMac. Now that I',ve done this, I log in into my account, and I can't seem to access the overview screen of my cloud membership where i can see all the icons of the software programs to install.
How do I access this? I think I first need to install the application manager, but don't see where i can do this.
Tom

Hi Tom,
Sorry to hear about your difficulties.
Can you launch Adobe Application Manager from either the Start menu (Win) or Applications folder (Mac), sign in with your Adobe ID and install all available product updates.
Can you license products launching in trial by clicking the "License this software" button and signing in with your Adobe ID?

Do I have to close all background apps (i.e. apps which appear in multitasking) before turning off my iPad? Is it safe to shut it down while having these apps in the background?

Do I have to close all background apps (i.e. apps which appear in multitasking) before turning off my iPad?
Is it safe to shut it down while having these apps in the background?
When you shut down operating systems like MS Windows or Mac OS, they automatically close your active applications before shutting down, is this true for iOS 7?

Thanks, I do appreciate your immediate response to my question.
BUT your answers revealed an explicit controversy about background apps ... close them to save power and performance OR don't bother to close them as they are idle or inactive!
This dispute is resolved by APPLE in the following link:

My original question was: Is it necessary to kill background apps before shutting down my ipad to avoid any harm to the apps or the OS?

Z3 rebooted to factory settings while having it in my pocket, photos lost on SD card

My 3 day old Z3 rebooted to factory settings while having it in my pocket. I was out for a five hours walk and have used it serveral times during the walk to take photos. They were stored on the SD card. Battery was on 73%. At the end of my trip I noticed it asked for my pin code to unlock the sim card. I used my newly set pincode for simcard and it worked fine. The telephone was set up with screenlock as well, but that has disapeared together with all my installed programs and my photos and videos on the SD card. The lock screen goes automaticlay on after 15 sec so I find it strange that I should be able to push the right buttons, in my pocket, by just walking, to perform a factory reset?Any suggestions on why and how to restore my photos on the SD card?

This was Sony's answer to my question: Sophia: Hi, just looking into this for you won't be long.Sophia: I have had a read of the thread and due to the low number of people posting on the forum over the past year I ca confirm this is not a common problem. If you have already tried what has been advised on that forum and the issue has not been resolved, I advise running a software repair on your handset as this is most liekly to resolve the issue yoyu are experiencing.X: that is Sony's answer?Sophia: Yes.X: and what about all the lost data and picturesX: this is not an isolated incidentSophia: I understand that it has been experienced before but there has been an extremely low number of people who have experienced the issue, it is not a known fault. As previously suggested, a software repair is likely to resolve the issue for you.X: how do I recover the data that has been lost?X: I must say, I was hoping for more support, from a support chatSophia: Unfortunately once the data has been lost, there is no way to recover it I am very dissappointed in the level of care from Sony. Took a long time to get the final reply, and it's apparently not a known fault, so it's my problem. If it's happened to multiple people, it's a fault.

Can more than one log in on a computer share an iTunes account while having a separate itunes store log in?

I'd follow-up with that question by asking?
a) Can someone in my family share the the library on their computer while away at college using files put on another external drive
b) Where is the **** ITunes Library file stored? In the same folder where my data is stored?
c) what happens if you keep the Itunes file organized, but do not copy them into the designated ITunes folder?
Lnow that is a lot. However with ICloud here and my having three power PC computers this info is crucial since the previous instructions to copu to my idisc and put them in my various machines will be gone\.
Thank's
Theo

I will share with you what I have done to manage this with my family. While the solution isn't without flawes, it seems to do the trick. First, you need to have one person who is managing the synching of everyone's devices. In my family, I have three iphones, about to be four, and five ipads. We all synch to the same apple ID to allow one another to take seemless advantage of our Itunes, which is on our Imac. To synch individual music or video interests, we simply select which playlists we want and manually synch that way. A couple of us use imatch and the cloud to make the entire library accessable as well. With respect to the imessage, mail, contacts, etc. we each have a gmail account for our individual emails, contacts etc. So for instance, my forth grade daughter has a gmail account that we choose to synch her contacts, calendar, etc to and then that is also the account where she receives her imessages from on her ipad and itouch. My son, who has an iphone and ipad, does the same thing, but under settings, he goes to imessage and checks his phone number and his email as his preferred way to receive imessages and texts. My wife and I do the same thing. To avoid having everyone see one anothers contracts etc, we only synch contacts from our individual email accounts. Here is the downfall to this: When you update your phone or add a new device, apple always wants to reset everyone's facetime and imessage settings and then low and behold we are all receiving imessages from one another's friends etc. To work around this, I simply take each of their devices and go to their imessage settings and only check the email and phone numbers relative to their devices. I dont' know is this is the best solution, but it seems to work for us.

Movie won't download from cloud while having a billing issue

I've got a billing issue with my account which hopefully will be resolved in the next 48 hours, but in the meantime, a movie that I had already purchased will not download from the icloud to my IPad mini. Everytime I try to get it to download it takes me back to the billing screen. I've already purchased this movie several years ago and shouldn't be having this issue, but here I am. Is this something new that's going on with ITunes with this new update, and if so ***, I've already paid for this movie and my son wants to watch it so why am I having this issue while waiting on a different issue to be resolved?

Click here and ask.
