How does processScope restore its state?

Hi, when a process returns, the process scope is supposed to return to its original state. How does it do that? is it a deep copy? How does it handle mutable objects?
also, how does the process scope work with the back button?

anyone?

My Daughter changed her Apple ID, not sure why. Then she changed it back to the original. She has lost $50 on her iTunes. How does she restore the funds?

How did she change her AppleID?
If she simply updated the AppleID (not created a new one with a new email address), log out then log back into iTunes store.

Windows domain controller in a virtual machine: how dangerous is saving its state for a short period of time?

I have a Windows Server 2012 R2 virtualization cluster. All the hosts are connected to an external storage system, and virtual machines' files are stored on external volumes (CSVs). All the hosts and virtual machines are a part of the same AD domain
(mixed Windows Server 2012 RTM / 2008 R2 domain controllers). All the domain controllers are running in the virtual machines on the hosts of this cluster.
To prevent problems when all the hosts are turned off and then on simultaneously (for example, because of a power failure) all the domain controller VM files has been placed on local disks of the virtualization hosts (not on the Cluster Shared
Volumes). As Hyper-V services don't depend on other Windows Server services (except its networking components), it means that my domain controllers can always start, providing the virtualization host can start at all. However, it also means
that those DCs cannot be (quickly) migrated to other hosts while their current hosts are being rebooted. So if I need to reboot a virtualization host to install new updates, for example, I have to shut down the corresponding DC, reboot the host
and wait for the DC to finish cold boot and come back online. It means some interruption of service for our users, which, in turn, requires me to perform the reboots late in night.
The downtime can be significantly decreased by saving the state of the VM in which the DC is running. However, all the articles I've found on the Internet strongly recommend against it. I'm trying to understand why this recommendation was issued in the first
place. However, I'm unable to find a clear explanation. I've found some statements that saving state of a DC can cause serious AD replication problems because of tombstoning, and that the password of a DC computer account may be changed
while the DC itself stays in the saved state, which could prevent the DC from connecting to the domain after its state has been restored. However, those considerations are non-significant when we discuss a short-time
(5 to 10 minutes) saved state.
I work with AD and virtualization long time, and I fail to see any danger in saving state of a DC for several minutes. In my opinion, after its state has been restored it would simply replicate all the AD changes from other DCs, and that's all.
What's your opinion?

Hello,
as stated in "http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv(v=ws.10).aspx"
Operational Considerations for Virtualized Domain Controllers
Domain controllers that are running on virtual machines have operational restrictions that do not apply to domain controllers that are running on physical machines. When you use a virtualized domain controller, there are some virtualization software features
and practices that you should not use:
Do not pause, stop, or store the
saved state of a domain controller
in a virtual machine for time periods longer than the tombstone lifetime of the forest and then resume from the paused or saved state.
This may sound as it is supported to store it for shorter times and use it.
BUT recommendation also from the Hyper-V Program manager in
http://blogs.msdn.com/b/virtual_pc_guy/archive/2008/11/24/the-domain-controller-dilemma.aspx recommends against using them.
Also best practices

How does BDB update its secondary index?

I am asking how does Berkeley DB update its secondary index?
For example, in a BDB table with key value pair ``<k,v1>``, the index database would have reversed pair like ``<v1,k>``. Upon an insert (or essentially an update) ``<k,v2>``, base table record ``<k,v1>`` should be overwritten to ``<k,v2>``.
But how would BDB deal with ``<v1,k>`` in the index table? Will it delete it immediately?

Hi,
As long as you correctly open the primary database and secondary index database, and associate the secondary index database with the primary, any update on the primary database will be reflected in the secondary index.
For more information, please refer to Reference Guide for Berkeley DB -> Chapter 3. Access Method Operations -> Secondary Indexes section.

How Does iPad Update Its Clock?

I noticed that time on my iPad 3G 64GB is slightly different (less than a minute) from time of my MacBook Pro, that itself is different from time of my iPhone.

Your MBP updates time from a time server over the internet. The iPhone sets the time using the cell phone system. My AT&T iPhone is always 1 minute behind my MBP.
I think that the iPad syncs time with iTunes or through the WiFi network. My iPad which syncs to my MBP and uses WiFi from an Apple AirPort Extreme has the same exact time as my MBP, down to the second (they switch minutes simultaneously). I might be wrong on this point, so if someone knows something more, I will stand corrected.

Hi Niel . So they must do this for every single song , correct ? Because I have notice some albums from certain Artist that Apple doesn't have but yet they do have some songs from these Artist . Can members request songs to Apple to try to get ? Thanks

How does JEditorPane determine its preferred size?

Could someone explain how JEditorPane determines the initial preferred
size? Its default sizing is not giving me what I need and I'm not sure
how to control it, other than explicitly setting the size with
setPreferredSize().
A simple example:
        String s = "1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 10 20" +
                   "21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39";
        JEditorPane ed = new JEditorPane("text",s);
        JPanel pan = new JPanel();
        pan.setLayout(new BoxLayout(pan,BoxLayout.Y_AXIS));
        pan.add(ed);
        JFrame f = new JFrame();
        f.getContentPane().add(pan);
        f.pack();
        f.setVisible(true);This code generates a window that shows one line, with "1 2 3 4 5 6 7 8 9"
showing. I'd like to have a larger area showing initially.
Does the choice of layout manager effect this? (I actually prefer to use
TableLayout; the above example with a 1x1 TableLayout and widths set to
PREFERRED yields exactly the same results.)
Thanks,
bw

How to refresh/restore VIEW STATE of a JSF component? urgent help needed!

AOA guys,
I am using Jboss 4.0.5, JSF 1.1.2 and DOJO framework to handle ajax request.
In my project, I am using A4J hidden fields to store values associated with an html anchor tag and use these values to update <h:outputText> dynamically (an ajax request).
But when i click that anchor link a more than 15 times the message appears as a prompt that view state couldn't be restored - reload page.
I think it is because that in JSF 1.1 default value of
om.sun.faces.NUMBER_OF_VIEWS_IN_LOGICAL_VIEW_IN_SESSION is 15, So i can't store more than 15 View Id of JSF components.
My Question is:
_Without shifting to JSF1.2, how can i handle this restore view problem in my Java Code using phase listener or some other way so that if this view state problem will occur it atomatically restore the view ids?_
Please reply me soon?

After copying iTunes folder to new PC how do I restore its original library

I have two PCs, each with iTunes on it.
The newer PC has number of tunes that I've purchased from the iTunes Store. It has no playlists.
The older PCs has a large library of Cd-ripped music and numerous playlists.
I want to copy the old PC's library and playlists over to the new PC.
I understand that I can simply copy the iTunes folder from the old PC to the new one and the files and artist folders will be merged fine. Doing this will also replace the itunes.library.itl and "itunes music library.xml" files so I end up with my old playlists on the new PC.
But at that point I suspect iTunes on my new PC will no longer show its original library of files because its original itunes.itl file was overwritten.
How do I get iTunes on the new PC to add those missing tunes back into its library?
Windows XP Pro

Well, this is a helpful group.
I ended up conducting a test.
I copied the entire iTunes folder from the old PC to the new PC. The music folders simply merged with the existing ones so no music was overwritten except for tunes that existed on both PCs.
Afterwards, iTunes on the new PC showed all the old PC's tunes in the library and all of its playlists. Missing from the library listing were the tunes that had been on the new PC.
But using "Add Folder to Library" to have iTunes rescan the iTunes Music folder added back the missing tunes. All tunes that had been purchased on the new PC and were therefore licensed to that PC still play without any DRM probs.

How does migrating/restoring Mac OS X Server compare to Mac OS X?

I’m thinking of reinstalling the system software on our server (we have a bunch of problems we can’t get rid of) and I was wondering what the process is like.
We have a Time Machine backup and I was wondering how similar the process is to reinstalling/migrating a client installation of Mac OS X?
For instance does it give you the option to only restore files and data (such as Wiki content), or are you forced to restore all settings, users and preferences as well?
I’d prefer to just restore files and data and then manually recreate users and settings, in the hope of ridding ourselves of some of the problems we have (such as iCal server constantly asking for passwords and an inability to add or remove users using Server Preferences).

It's more a case of looking at the logs and not really knowing what I'm doing. Suffice to say I've taken the trouble-shooting road to my limit.
Mainly we have issues with iCal Server which keeps asking users for their passwords:
http://discussions.apple.com/thread.jspa?messageID=5936657
And now we have this error 14120, since 10.5.6, that causes us not to be able to add or remove users in Server Preferences:
http://discussions.apple.com/thread.jspa?messageID=8773646
I assume by the advice I'm getting from both of you that the migration tool for Mac OS X Server doesn't include the ability to bring only data files over minus all the settings and users?
I'm happy to do a clean wipe. I just want to be sure I can pull across calendars and Wiki data reasonably easily if I do it manually, as I'm not an IT pro. I'm only a CAD Manager and all my knowledge with these things is only through day-to-day experience.

Report does not save its state.

Description of my actions:
1. I click on column header for sorting by this column. (rows 1-10)
2. Go to the next report page.(rows 11-20)
3. No sort on this page. (rows 11-20)
Any ideas?

Hi,
how to achieve that attributes etc. from subtypes are rolled up to one single table?
Implementation of elements(types) of entity hierarchy depends on "Engineer To" flag - if it's set for related relational model then enity will be implemented as table. So for single table you need that flag set only for super-type (or root of hierarchy) and not checked for all subtypes.
"Subtree generation" is not a property, it's functionality allowing easy set up of "Engineer to" property for edited entity and its sub-tree. This is why it's always on "Do not preset".

Session state consistency - how does APEX keep session state across pages

I would like to know how the APEX develper tool keeps session state from being overwritten across mutiltple pages in the same Session. Because this is difficult to explain I'll use an example from withing the APEX dev tool
For Example:
1. I navigate to the page (4150) thet allows me to edit my Page 880 [Window 1]
2. I now do a Cntrl^N to Open a New Window in the same session (this opens on the same Page 880 in the new window) [Window 2].
3. In Window 1, I click an item to update ie I want to put a comment on the Unconditional Branch so click this to go to the Update page. I see the F4000_P4313_ID is passed in the URL (ie the context, UID of the Branch).
4. In Window 2, I change the page to 881 - ie this is overwriting my Session State variables for page 880 with page 881.
5. I click an item in Page 881 to update ie I want to put a comment on the Unconditional Branch so click this to go to the Update page. I see the F4000_P4313_ID is passed in the URL (ie the context, teh UID of the Branch).
6. In Window 1 (the Page 880), I add a comment to the Branch and 'Apply' changes. On returning to the Page the context has changed from 880 to 881 (as expected as Window 2 had overwritten the session state). Slightly confusing for the user as they did go from Page 880 not 881 but ok
What intrigues me is how the Edit Branch page applied the update to the correct branch [good !]. Why weren't the Branch Session state variables (ie the Branch for Page 880) overwritten with the Branch Session state variables for the Branch from Page 881 ?
Both navigations go to the same Page passing the UID of the branch, hence I would of thought the last navigation is the one that would be persisting (ie from Page 881 Window) ?
Any tips on preventing users updating the wrong record because of the Session State being overwritten would be most welcome.
Look forward to hearing from you.

Let me take a shot at explaining this.
Session state is stored in Oracle database tables. When a APEX page is rendered, those tables are read and the HTML is sent to the browser. When that page is submitted, all the HTML form inputs on the page are saved back into session state over-writing any existing values for that session
So, in your example, since Page 4313 has the hidden page item (the "GUID" of the branch), it doesn't matter if any other window has the same page open with some other GUID. Each page is a self-contained "unit" which has all the information necessary to properly process that page when it is submitted.
Think of it this way...in your example, when you have windows 1 and 2 open (window 2 was opened after window 1), go back to Window 1 and click the browser's Reload/Refresh button. Instead of refreshing the same page (branch 9000000), you will find that it will load branch 8000000! This is because session state is read from the database and when Window 2 was rendered, it has set F4000_P4313_ID in session state to 8000000.
Hope this helps.

How does cyrus flag the state of mail and can we preserve this ?

When I restore an e-mail account the user gets his mail as unread
What i am saying here is
We use imap accounts and I had to restore the mail from a backup, all the users got there mail back, but all as unread including the folders they created.
it would be handy to know

There is no reliable way of preserving the read/unread states when restoring.
