Questions on environments, backups, etc.

We are currently implementing Unifier with an expected go-live of early August. Am hoping I can solicit some feedback from some of you on a handful of questions.
How often do you do production backups?
Have you ever had to restore production to a backup?
How many environments do you have? Just uStage and Production or do you have additional environments?
How do you refresh your none production environments? How frequently?
Are you using Oracle's cloud service or are you self hosted?
Feel free to connect with me directly at [email protected]
Thanks in advance.

My recommendations are based on a self-host model:
>> How often do you do production backups?
Rudy addressed this quite well - follow best practices for disaster recovery and data redundancy and you will be set.
>> Have you ever had to restore production to a backup?
I know of a few incidents across all customers over the past eight years where there has been a need to restore production from a backup. It rarely occurs but nonetheless is an important planning consideration.
>> How many environments do you have? Just uStage and Production or do you have additional environments?
Other environments worth considering include:
-- a training environment with periodic rollback to training baseline.
-- a second sandbox/uStage for testing releases prior to updataing your other environments.
>> How do you refresh your none production environments? How frequently?
Training is often refreshed on a semi-quarterly or quarterly basis depending on your use.
>> Are you using Oracle's cloud service or are you self hosted?
Cloud service - but I have extensive experience with self-hosted environments as well.
Good luck with your release!

Eternal ball, flashing question mark, kernel panic, etc... all! HELP!

Think this is a good, one... Here is the story:
Some apps will crash, that always happens, right? So I did not pay much attention to it until it was way too often. Learned about disk utility, repaired permissions on a regular basis and moved on. But then... One day disk utility told me there was something that could NOT be repaired. I ran and bought an External HD (usb.. not a good choice, but I found out that too late for an exchange). Backing up from there on was kind of a weekly thing.
But nothing to worry about, I could still use my iBook pretty well and with no problems. Then... one fine day I could not SAVE ANYTHING! Everything was working "normal", but when I wanted to save my work. It told me that I could not do it! Not even making a new bookmark from Firefox!
So I did verify and repair from disk utility, and I ran the hardware test giving me the following:
*ERROR CODE: 2STF/8/3:ATA -100 ata -6 -Master*
I have no idea what that means, but I used it to look for help online and everything pointed out that my HD needed to be replaced. I believe at this point is when I met the flashing folder icon with the question mark. Suddenly it would not detect the HD! But then... after turning it off and on for a few times it would see it and start-up normally. In one of those lucky start-ups I backed up all I thought was important in the external HD and made a clean install of OS X. Oh... and it is fun to try to install OS X when.. there is no HD in the list to pick for your destination! After a lot of patience, it would show up, but then is when I met the kernel panic mesg! After a few more tries (yes, I am a very patient person... sometimes), I finally could make a clean install of OS X. I even partitioned the HD to make sure there was nothing there.
Ok... seemed like it liked it.. but after a little while, strange things happened again, and after the restart, the blinking folder with the question mark again...
So... no choice, have to replace my HD right? I get a brand new Seagate, 120 Gb, 5400 rpm. Followed instructions from ifixit.com and after 3 hours (and a lot of fun!) I replaced the hard drive on my beloved iBook. This was really fun!
Installed the software on the new HD.. everything looks fine... for a few minutes. I tried to use right away what I use everyday to see if it works: web browser, iTunes, Activity Monitor, played a dvd perhaps, etc... And..? Nop... started crashing again... Got the blinking question mark after restart, etc. But now.. the hardware tests reports me no problems.
Ok... it was not the HD, but I already bought one, and installed it myself!... lets move on and see where is my problem.
Could it be the ram?
This model has only one slot of removable ram, and a built-in DIMM that I cannnot replace +(or can I?)+, so I remove the one I can, and restart it without it. First it looks fine again, everything is working, but after a while it starts crashing again. So.. it's not the ram... or at least it's not +this one+.
So... I think its time for a Professional to take a look at it, right?. So I took it to a Mac Store (not Apple store) and explained EVERYTHING to the guy that received my beloved iBook, he takes notes and tells me that it has to stay for a few days. After 1 week I receive a call from the store (another employee) telling me the sad news that my HARD DRIVE NEEDS TO BE REPLACED! And that they were very sorry but they cannot recover any of my data... what data?? All that was there was the OS!!!
So... a deep breath and I explain to him everything over the phone. Ok.. he says he will talk with the tech-guy and I'll hear from them in a few more days. I did...
I was very glad to hear it was a cable that connects the HD to the Logic Board (that's what I understood.. I think). That this was only 20 dollars, but somehow, with the labor I ended up paying around 100 dlrs! I found out later that apple changes this cable everytime they upgrade a HD.
Ok.. 200 dlrs spent already ($100 on my Seagate HD + $100 for the cable..), but if get my iBook to work again I'll be happy.
So I go home and start to work on installing and making everything work again: firefox, iTunes, fugu, tried cyberduck, taco, ... everything looked fine. But after a while... it happened again. Sometimes I don't even get the blinking folder, just a grey screen. I turn it off, and then comes the blinking '?' or it starts-up... and if it does, after a while it would crash.
(I started this post on my iBook, and I was like 2/3rd's through when I got the ball... and no response at all... tried force-quit... and nothing, had to power off..AND start this post all over again on my girlfriend's!!! )
So here I am... Of course I want to take it back to the guys at the MacStore and
complain about their poor job... But does anyone here has a good idea of what could it be?
My thoughts are something like this: Seems like if you do not use a lot of memory (I only have 512 Mb total, so a lot of it comes from the virtual, right?) it works fine, but somehow if it reaches a point where it needs more than a certain amount it would crash. I dont know if this even makes sense, but that's my feeling. The guys at the MacStore told me that they tested around 100 times restarting the computer and it looked fine, so yeah... if all they did was use a software to restart once and again, and again... without really using the memory, they would not see the problem, right? The problem comes later.. when you use the iBook.
Could it be then that the problem comes from the ram that is built-in? If so.. can this be replaced? Is it worth it? Can I do it myself?
Too many questions...
Any thoughts would be more than welcome and...
Thanks for reading all the post!
E

yeah....
the problem is that I do not have a firewire external HD, and it will not boot from my usb external...
Anyway... I am back from the MacStore and the guys told me that the next step would be to replace/work on the logic board, and that that was too expensive a job to do an an old iBook like mine, they did not recommend it to anyone (they told me they charge between 600-800 dlrs for this kind of job).
So... seems like my iBook is in a very bad shape.
I saw DT&T online and it seems like they do the job for half the price of the MacStore (before shipping costs), but... still, is it worth it?
I was thinking in the possibility to find someone who sells a used iBook in pieces because of a crashed screen or something, to get another logic board and try to replace it myself, but... is this something an amateur can do by himself?
Haven't checked ifixit.com for that yet.
Any ideas??
Thanks..

I forgot my security questions and my backup email that it sends the reset to isn't working! Help

I do not know my security questions and my backup email that it sends the reset to isn't working. Help!

If you don't have access to, or don't have, a rescue email account (and you won't be able to change it until you can answer 2 of your questions) then you will need to contact iTunes Support or Apple to get them reset.
e.g. you can try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management , and then 'Forgotten Apple ID security questions'
or try ringing Apple in your country and ask to talk to the Accounts Security Team : http://support.apple.com/kb/HE57
When they've been reset you can then use the steps half-way down this page to change/add a rescue email address for potential future use : http://support.apple.com/kb/HT5312 . Or you could change to 2-step verification : http://support.apple.com/kb/HT5570

Thunderbolt / USB3 questions about external backup drives for my new MacBook Pro

I have a new MacBook Pro retina 13". It has two USB3 and two Thunderbolt2 ports.
Until now on my iMac I've kept two backups on two WD USB2 drives. I have never had any problems with any of my WD Passport drives. One for Time Machine and one for CCC (a complete bootable clone incrementally created at 3:30 am every day).
I'd like to get new portable drives for my MBP for these backups going forward and have a few very basic questions, since this is the first time to have a device with a USB3 port, and the first time I even heard about Thunderbolt.
If I get a USB3 drive and need to use it to restore things on my older iMac, which just has USB2, will it generally connect and run with USB2 at a slower speed? Or would I have to get a drive with both USB2 and USB3 ports?
Is Thunderbolt just an Apple thing? Or is it a new standard widely used by peripherals now? I just never heard of it before. Is it faster than USB3?
Is it common for drives to have both Thunderbolt and USB2 connections?
Are there "hubs" for Thunderbolt like there are for USB? Considering the limited number of ports, I'm wondering the best way to connect 2 external drives. My iMac has 4 USB2 ports on the back, and I connect one drive separate to each of those ports, rather than going through a hub.
Is USB3 like USB2 in that if you have even 1 USB2 device (e.g. my Logitech headset) connected to a USB3 hub it will slow down everything on that hub to USB2?
Any recommendations for good, portable backup drives?
Thanks,
Doug

Hi Doug,
Lets see if we can address some of these:
If I get a USB3 drive and need to use it to restore things on my older iMac, which just has USB2, will it generally connect and run with USB2 at a slower speed? Or would I have to get a drive with both USB2 and USB3 ports?
USB3 is "backwards compatible" with USB2 so plugging a USB3 drive into a USB2 port should work, but at USB2 speeds.
Is it common for drives to have both Thunderbolt and USB2 connections?
Drives sold as Thunderbolt often (not always) have USB as well, drives sold as USB never (in my experience) have Thunderbolt connections.
Are there "hubs" for Thunderbolt like there are for USB? Considering the limited number of ports, I'm wondering the best way to connect 2 external drives. My iMac has 4 USB2 ports on the back, and I connect one drive separate to each of those ports, rather than going through a hub.
Yes there are (but don't expect them to be comparable in price to a USB hub) e.g. see here: http://www.belkin.com/uk/p/P-F4U055/
Is Thunderbolt just an Apple thing? Or is it a new standard widely used by peripherals now? I just never heard of it before. Is it faster than USB3?
I'ts an Apple technology (like firewire) and is far from widely used on peripherals. There ARE Thunderbolt drives etc by companies such as LaCie, WD etc but they are still very expensive (3 or 4x the price of an equivalent sized USB drive). For some this was a worthwhile expense since Thunderbolt is many times faster than USB2. But the arrival of USB3 has, in my opinion, changed the landscape. Yes, Thunderbolt is theoretically faster than USB3 (up to twice as fast) but benchmark tests have shown that in real world situations, the speed difference varies from no difference to Thunderbolt being 25 or 30% faster. When you take into account that USB3 drives are more common than Thunderbolt and are only a little more expensive than USB2 drives at present, then it's a "no brainer" as far as I am concerned.
Hope this helps.

Questions on user security etc

Hello, we are getting ready to implement an SOA strategy within our company and have decided to use XI as the interface to SAP from any other system. We have some (I have) questions on what some of the different approaches are for security. If anyone could help me with the following info (I have searched and searched and just not clear)
So before reading the scenario's here is the main thing I am trying to accomplish. Have webservices that take in a userID and password that is not stored in XI but on our LDAP server (like we have in the portal) and pass this to the back end ensuring user has writes to do desired function in sap. We want every user id so we can track if someone creates an purchase request etc, (instead of setting up a system id, audit puposes) So with that background I have the following scenarios
Scenario 1: Have a single sign on like the portal, so the user signs on with there normal account and XI accepts and forwards the request (this would mainly be a webservice) (I have seen some single sign on documentation but curious if it works in XI as it does in the portal)
Scenario 2: Same as one, but use ADS/LDAP as our authentication engine.
Scenario 3: Have userid put in, but no authentication is done on the front end but user is authenticated against the sap system and if allowed rfc/proxy is executed otherwise error message unauth is returned.
Scenario 4: Is the propagate principle mainly just to ensure the user has all rights to run all calls within internal XI procedures and wouldn't really apply to just ensuring user has rights in the backend?
I am sorry for the long question, I do reward points and I am just trying to get started on the right path with XI
Cheers
Devlin

Hi,
For your above cocern XI have provided the feature of Principal propagation with SSO ie.e Single sign On.

also you could provide SSL Configuration across the firewall
You need to setup SSL layer for HTTPS endpoint.
Possible HTTP security levels are (in ascending order):
HTTP without SSL
HTTP with SSL (= HTTPS), but without client authentication
HTTP with SSL (= HTTPS) and with client authentication
HTTPS comes in two flavors, both ensuring the confidentiality of data sent over the network

Back up Question when using backup not Time Machine

Hi there, I currently have my Time capsule configured as a file server sharing my files between 3 macs on the TC's wifi and also via the back to my mac service, while outside my home. The 3 macs connected also use the TC as the time machine back up disk. This setup works fine but I have concerns about reports that TC's can just die and the files contained on it could be lost. To combat this I have set my macbook to perform a backup using the backup program once a day. This is set to backup the whole TC excluding the 3 Time capsule files to an external firewire disk. The problem seems to occur after about a day or two, when the backup program reports a failed backup due to not enough disk space but I don't understand this as the external firewire disk has enough space unless it is trying to carry out a complete backup again. Once the initial backup is done (about 6 hours) I can manually trigger a backup which completes in a matter of seconds and is labelled on the firewire disc as incremental and contains a few mb. Can any one explain this to me? and any posable fixes.
Cheers
Here are the figures.
TC = 500GB
TC Files= 87GB (Excluding the 3 TM backups)
Firewire drive 160GB
Initial Backup file size 87.7GB
Successful Incremental Backup file size 4.2mb (done on same day as initial backup)
2nd Sucsesfull Incremental Backup file size 2.1mb (manually triggered day after initial backup)
Error backup file size 29kb (auto triggered day after initial backup)

The current version of Backup won't do a full backup (after the first one) unless you tell it to, via +Plan > Full Backup+ from the menubar. But it will back up everything that was added or changed since the last backup, so an Incremental backup can be quite large.
A clue may be lurking in the log for the failed backup.
From the main Backup screen, select the Plan in question, then from the Menubar, +Plan > History.+ Then select the "event" in question and click the +View Details+ button at the bottom.
If the log doesn't tell you much, copy and post it here (but if there's a long list of files copied, leave out most of that).

Some questions on interrupts, threads etc

Havng gone through some documentation on interrupt, kernel level threads etc in WDF, I got a couple of questions:
1) Can a hardware interrupt be preempted by another interrupt in a single processor system?
2) What exactly is the difference between thread preemption and thread interrupt? Doesnt both mean stopping the current thread and putting it aside?
3) When an iterrupt is handled by an ISR, does the ISR always have to schedule a DCP? If the ISR itself can handle the interrupt, is the DPC needed?
4) I understand that spin locks are used for synchronisation at IRQL <=DISPATCH_LEVEL. EVT_WDF_IO_QUEUE_IO_WRITE works at <= DISPATCH_LEVEL. If I set Synchronisation scope of a write queue as SynchronisationScopeQueue, should I still go for a spin
lock, if the write callback and say an ioctl callback uses a shared resource?
5 )Kernel dispatcher objects are mutex, timer, event, semaphore etc. But If i use a fast mutex or guarded mutex or oridinary mutex using say, KeAcquireFastMutex() isnt that then a kernel dispatcher object? What this distinction? Why should we go explicitly
go for kernel dispatcher object?
6) How can timers be used for kernel level synchronisation? How different is this from timers created using WdfTimerCreate()?
7) It is said that "Never wait on a kernel dispatcher object in any driver routine that can be called at IRQL>=DISPATCH_LEVEL.". Does it mean
we should not use synchronisation mechanisms in this level? Or if we can use, should the thread try to acquire a lock with a zero wait time? And proceed if it could acquire the lock and return if the lock was not acquired?
8) I understand that in order to execute an interrupt, a driver does not create any special threads but use a thread that happens to be running at the moment( arbitrary thread ) . My question is, in what way is this accomplished? What aspect of the arbitrary
thread is the interrupt using ? The arbitrary thread must obviously have been written for another purpose.

To answer the questions:
#1   An interrupt service routine (ISR) running a lower IRQL may be interrupted by another ISR running at a higher level.
#2   Having never heard of a thread interrupt, all I can say here is that a thread may be pre-empted for a lot of reasons.
#3   An ISR does not have to schedule a DPC unless it needs to do work that it cannot do at high IRQL.
#4   Assuming that the Write and IOCTL are on seperate queues, yes you need a a lock to protect shared resources.
#5   As the name implies kernel dispatcher objects allow scheduling (i.e. dispatching of another thread), while things like spinlocks do not.
#6    Timers are just another dispatching object, i.e. one can wait on them the same way one waits on a mutex or a semaphore. A WDF TIMER is basically a wrapper around a regular timer to take care of some of the housekeeping (particularily
with respect to stopping the driver etc)
#7     If a routine is running at DISPATCH_LEVEL you are limited to spin locks for synchronization. You can with a zero timeout check the status of a kernel dispatcher object.   In general, routines like this should be
designed to only use spinlocks.
#8    An arbitrary thread is just that, it may be a thread in any process. Basically a currently running thread is grabed and used to run the interrupt so that the scheduler which has overhead and is not designed to run at interrupt level
IRQL's does not need to run.

HT201269 A question about iTunes backups.

I have backed up my old iPhone that used Ios 6. Now I have a new iPhone and my question is: Can i restore that new one if it has ios 7? Will it change back to Ios 6 or not??? Thanks!!!

Yes, you can restore the new iPhone from the old one. It will not restore the older version of iOS; that's not part of the backup. To see what is in the backup, go here;

[SOLVED] Basic question about x2go, freenx, etc. compatibility

My goal is to simply enable remote desktop on my soon to be headless server. Given the number of posts here at Arch explaining the trouble with freenx and the Arch support of x2go, I'm confused there is not more talk about their compatibility. And as I've just discovered, they're not:
"Various open source terminal server projects such as x2go also use the NX protocol; however, x2go is not compatible with other NX servers and clients." (NX Technology)
This leaves me in a bit of a pickle. CentOS doesn't support x2go, and Arch doesn't support freenx. What's the best interoperable solution then? Either a sever app which supports x2go or a client app that supports NXX?

CentOSers are very persnickty about how you're supposed to maintain your system in terms of non-core packages etc. etc. And x2go is not coming up in the forum, wiki, or in the repositories (via the commanline tool yum). Read the response to my question about installing vim7.4. Hell, you can do _whatever you want_ to your system, but that doesn't mean anyone's going to help you when you run into trouble.
That comment strikes me as perfectly reasonable. The comment is pointing out that you are trying to use the wrong tool to do the job. The tool in this case is the distro - CentOS is not intended to be used in this way (for this job). Of course, if you insist on using a spanner to hammer nails, you are free to do so. But you can't really expect your local DIY shop to help you use the spanner when the nails don't go in straight rather than suggesting you use a hammer instead.
It is just like somebody who comes here and asks how they can stick with a known-stable set of packages while getting security updates. That's not what Arch is designed for so if you try to use it that way, you'll have a hard time. Of course, you are free to do so if you wish. But if you ask for help, you'll be pointed to another distro because that is the right answer.
It has nothing to do with being "persnickty". The answer is the most helpful answer somebody can give you.
Note: I'm assuming the description of CentOS, Fedora etc. is correct. I know the description of Fedora to be correct but I don't actually know anything about CentOS. But on the assumption that description is also correct, that answer is the most helpful answer somebody could give you, even if it is not the answer you wanted to hear.

Decide on my own where my backup etc is saved by Itunes

Hi @ll
I´d like to ask how I can prevent ITunes to save backup on my Boot Hard disc.
Problem is that I have a SSD hard disc with very low space which was intended to be used only for windows.
Now Itunes is installed on my second hard disc but nevertheless it saves a lot of datas (around 30gb ) on my boot device.
and now I do not have any free space....
Can anyone let me know how I can change that, so Itunes saves ALL datas on my second hard disc
Thank you in advance and best regards
Flev

While it doesn't seem possible to change the location used by iTunes for the backups and other configuration data, you can redirect the backup data to another folder using a junction. Install NTFS Link. Move the folder <Profiles>\<AppData>\Apple Computer\MobileSync\Backup to another location, then create an empty folder called Backup in <Profiles>\<AppData>\Apple Computer\MobileSync and use NTFS Link to create the junction.
I suppose you could move a higher level folder like Apple Computer in the same way, but the bulk of the data created by iTunes, aside from your library, will be the iOS backup folders. Note that I've tested iTunes with the Backup folder and it works. I've not tested redirects on any of the parent folders and it is worth noting that with general library writes (media etc.) iTunes actually breaks any junctions that have been created. Different parts of the application obviously use different system calls.

A question about partial backups.

In the usual way I backup my iMac to an external hard drive using 3rd party software and that's fine. But for additional security I bought two additional solid state drives of about 60 GB so I could make extra copies of some important files that change frequently.
My question is, what's the best way to backup these smaller SSDs? I can plug each into the main external drive and the iMac but not into each other -- can't daisy-chain them. Is there software made just for this?

There is no software for daisy chaining two drives that cannot be daisy chained. You can use your backup utility or some other utility to backup the files you want individually to the SSD.

IRC question - connecting to server etc.

Hi everybody,
first of all : I don't know where to post this kind of question, therefore I post it here, because I'm a beginner in this area.
Can I connect to a IRC Server with my Java application? I think of something like this:
I start my java prog and specify : connect to server irc.<whatever> , then I join a channel with my username and password.
I know I could use an existing IRC Client, like MIRC or something else, but this is just the beginning of my question.
Can I get the output of this channel (what is posted by the users) and append it in e.g. my JTextPane ? (i know how to append text etc.)
I would appreciate any kind of help, if you know good links etc. I thankful too.

Hmm...first of all thanks for your answer.
Where do I have to look for the "semantics"? Is RFC 1459 correct?
Can I connect to an irc - server like to a website (using an URL object) ?
I'm a noob concerning all the network stuff , but I appreciate any kind of help.

Question about iCloud backup

Broke my phone today and have a shattered screen. Cannot access anything via phone. Went to iCloud to get my contacts and info I need and there is nothing there. It says it backed up last night. Any idea how I can get my contacts and info?

Hello,
I have a question. It say that you have to be pluged in and locked in order to backup my iPhone to iCloud. Does it really have to be locked?

Question?? Backup Assistant - Going from BlackBerry to Droid

I am going from a BlackBerry Curve to a Droid X. Do I need to use the Backup Assistant or can I connect the information on my Gmail account (Contacts etc) to the Droid X.
I have the BlackBerry Desktop Manager and use this to backup my phone...do I really need to do anything or can I activate my new Droids?
Thanks, Tim

I would think you have your contacts already on your online account. If yes then do this.....
1. Go to Verizon Wireless and log into My Verizon. If you do not already have a My Verizon login and password select the “register” link.
2. On the My Verizon landing page select either “My Contacts” from the account actions on the right side of the page, or the “Contacts” button at the top of the page..
3. Export the .csv file:
a. Select the contacts that you want to export. If you want to export the entire list use "Select All".
b. Select the "Export Contacts" function.
c. Select the option to export contacts in "CV (Outlook)" format.
4. Save the exported .csv file to your computer.
5. Go to mail.google.com and log in. You will need to register for an account if you do not already have one.
6. Select “Contacts” from the menu on the left side of the screen. Once on the contact page select “Import” in the upper right hand corner.
7. Follow system prompts to import your .csv file.
8. Activate your Android device.
9. Sign into your Gmail account on your DROID. Contacts will sync automatically over the air.

Questions about iPhone backup?

I am iPhone novice,so i have some questions about iPhone Transfer included iTunes.
1. Only back up iPhone files via iTunes?
2. iTunes just can back up address list and calendar?
3. i want to back up plug-in,patch,application program,game ect, how to operate iPhone backup?Anyone can tell me simple&professional tutorial about iPhone?Or introduce a good iPhone Transfer like or better than iTunes.
Appreciate your detailed answers! Thanks in advance.

iTunes is required to transfer iTunes content from your iTunes library on your computer - music, movies, TV shows, podcasts, 3rd party apps, and selected photos from your computer to your iPhone. iTunes also serves as the sync conduit for contacts and calendar events between your iPhone and the supported address book and calendar application on your computer.
iTunes creates and maintains a backup for your iPhone which is updated by iTunes as the first step during the iTunes sync process. The backup does not include all data on your iPhone. The backup does not include any iTunes content - music, movies, TV shows, podcasts, or 3rd party apps. All iTunes content on your iPhone should remain in your iTunes library on your computer and the backup doesn't include any photos transferred from your computer. All photos transferred from your computer should remain on your computer as well.
This link provides the data that is included with your iPhone's backup.
