Meaning of VLSN and others
1. I know LSN is log sequential number for each record. What is VLSN?
2. check pointer generates a snapshot of database which includes all latest records, and then the cleaner can clean deletable log files. My question is if the check pointer applies an incremental mechanism so that snapshot 1 (immediate previous one) + snapshot 2 (current one) = the whole database? It seems to be this case due to the DirtyMap data structure (something like that) .
Thanks.

VLSN is a logical/virtual LSN that is used only in replication groups, and is a shared identifier for log entries among all nodes in the group. Each node has logs with different LSNs, but the same VLSNs. See the replication "getting started" guide.
The Checkpointer flushes just enough of the internal Btrees to enable a fast recovery (when opening the environment) and to guarantee that deleted log files will not be referenced by the active Btrees. The last checkpoint has these guarantees, and there is no relationship to the prior checkpoint.

JDK 1.4 license clauses about Software Updates and Other Software
Does anyone know what these clauses in the JDK 1.4 license mean? There is an old thread on this at http://forum.java.sun.com/thread.jspa?threadID=219875&start=0&tstart=0 but there was no response from Sun. I'm using the JDK in a Tomcat server application -- should I be worried that pieces of the JDK will be updated on my server without my knowing it? Or does this refer to applets downloaded to a browser?
From http://java.sun.com/j2se/1.4.2/j2sdk-1_4_2_10-license.txt:
7.SOFTWARE UPDATES FROM SUN. You acknowledge that at your request or consent optional features of the Software may download, install, and execute applets, applications, software extensions, and updated versions of the Software from Sun ("Software Updates"), ...
8.SOFTWARE FROM SOURCES OTHER THAN SUN. You acknowledge that, by your use of optional features of the Software and/or by requesting services that require use of the optional features of the Software, the Software may automatically download, install, and execute software applications from
sources other than Sun ("Other Software"). ...Just means that applets and other products so enabled can and will (after optionally asking for permission) connect to the net to download libraries they need if and as needed.
The JVM provides that functionality so it's in the JVM license agreement.
Nothing sinister, Sun isn't going to spy on you. -
I bought a mic for my ipod touch 2nd gen and the mic works yet when its plugged in the speakers dont work, meaning i cant hear, so skype and other similar apps are un-useable, is there a way in which the mic and speakers will both work together?
Looking at the details for this mic, it appears that the app has to have the option to use the internal specak when a mic is plugged into the headphone jack. Specifically:
NOTE: When MityMic is plugged into your iPod/iPhone you won’t be able to use the onboard speaker for sound output. You must remove the MityMic then play back your recordings. (The Skype app has an option to enable the onboard speaker even when the mic is plugged in, so you could use MityMic for placing Skype calls. However most other apps do not have this function.)
The above is from:

I just want to know if by purchasing a movie on iTunes, can I download other vertions of the same movie? Like subtitle editions and other language editions or get a lower prize when purchasing the same movie in a higher definition... Etc?
No. To purchase other versions of movies on the iTunes Store you'll have to pay full price for those versions. The content owners control this licensing and pricing to a large extent.

Your new recommended update appears incompatible with my and other's virus protection. How can we be sure we can safely navigate if your security on the older versions of firefox are lifted? It seems that many people are having this problem and have said they will return to Internet Explorer. Please advise as I prefer Firefox but cannot take the chance of malware and other infections. I would appreciate a hasty response.
No, it doesn't affect your anti-virus program, only the silly little extensions that some anti-virus applications install into Firefox that duplicate features which are built into Firefox = anti-phishing & web forgery protection.

after updating to Firefox 7.0.1, menu bar for Google(web ,image,video,map etc),yahoo, Facebook (message,notification,profile,home) and others site are disabled. even I cant log out from different sites cz the log out bar is completely disabled. I tried with Firefox 4;5 and 6, same problem exist . I tried by active all add ons for facebook, same problem exist. If I use internet explorer , I don't find such problem with it.
How can I solve this problem?Thanks a lot for your swift response. And sorry if it was a bit too hectic to go through my detailed query (which I did because it was misunderstood when I asked previously). As I've mentioned above, I was informed that updating to 5.0.1 would '''require''' me to '''delete''' the current version and then install the new one. And doing so will involve losing all my bookmarks. I guess I should have been more specific and detailed there. By losing, I didn't mean losing them forever. I'm aware that they're secured in some place and deleting and installing the software doesn't harm its existence. What I meant that if I install the new version, I'd have to delete the old one. And after installing the new version, I'd have to transfer them (bookmarks) back from wherever they are. Get it? When it updated from 3.6.9 to 3.6.13, and from 3.6.13 to 3.6.18, I didn't need to follow that process. They were already present on their own.
BTW, I'm having no problems with 3.6.18 but after learning about the existence of version 5.0.1, I'm a bit too eager to lay my hands over it.
Thanks for your help; hope this wasn't extremely long. -
ITunes Fix for Manually Moving Music and other Media
Intro
Any iTunes 7.x user who manages their own music library outside of the "iTunes Music" folder might be able to tell you that iTunes DOES NOT respond well after manually moving tracks from one place to another on their computer systems. In fact, any file you move becomes immediately unplayable in iTunes. And, if you're anything like I am, losing several years worth of song rating metadata and playlists is not a good incentive for change. However, one thing others might not be able to tell you is that there's an easy workaround for the problem and you get to keep your playlists, ratings and other info. Read on to learn about the workaround.
About the Workaround
The workaround is a simple hack I devised after recently transferring a good portion of my music library between hard disks and running into problems with iTunes. The fix steps provided below are intended to circumvent the problems with iTunes and give users the freedom to move songs and other media files on their computers while maintaining the integrity of both the ratings and the playlists. Meaning you won't need to manually update the song locations in iTunes one-at-a-time, which, at version 7.02 is the only way to accomplish this task using the program.
Please be aware that not all information is retained using this workaround. What will be lost are the following: the "Recently Added", "Recently Played" and "Top 25 Most Played" iTunes Smart Playlists; any media file play counts; last played information; and possibly some other data used only internally by iTunes.
So, if you're comfortable parting with some metadata while keeping your cherished song ratings and playlists intact during file relocation, read on to learn how to use the workaround.
Workaround Steps
The following instructions walk step-by-step through the process of this workaround.
Note: All backslashes used in file paths have been converted to forward slashes so that they will adhere with MySpace XSS security validation checks. These altered paths can still be copy/paste into Windows Vista's Explorer program once the Username is changed to the User Account where the iTunes files reside.
Preparing for the Move
Before you move your files, do the following:
1. Close iTunes.
2. Create a backup copy of the following files:
iTunes Library XML (iTunes Music Library.xml)
Note: Vista users can find the Library XML at C:/Users/Username/Music/iTunes
iTunes Music Database (iTunes Library.itl)
Note: Vista users can find the Music Database at C:/Users/Username/Music/iTunes
Moving Your Files
This part should be self explanatory, but while you do it make sure to note the following two things:
1. The path where the files were previously stored (e.g. D:/Music).
2. The path where the files will end up (e.g. E:/Music).
Execute the Fix
After your files are moved, complete the following steps to implement the fix.
Note: Do not open iTunes during this process.
Hack the iTunes Library XML
Once the files are moved the Library XML file locations will be out of sync. Follow the steps below to update them so that they now reference the correct file locations.
1. Open the iTunes Library XML with a Text Editor with a Find/Replace function.
Note: Vista users can find the Library XML at C:/Users/Username/Music/iTunes
Tip: Do not try to do this with Dreamweaver if your Library XML is greater than 10MB.
2. Perform a Find/Replace using the following inputs:
Find: Path from Step 1 of Moving Your Files
Replace: Path from Step 2 of Moving Your Files
3. Confirm your results, and then save and close the Library XML.
Delete the iTunes Music Database
Hacking the iTunes Library isn't enough to fool iTunes. Like the Library XML, the Music Database also holds the file locations of all of the media stored within the program. And it's smart enough to wipe out the Library XML hack if iTunes is opened before completing this step.
Ensure you have backed up the iTunes Music Database (iTunes Library.itl) and delete the file.
Note: Vista users can find the Music Database at C:/Users/Username/Music/iTunes
Back in iTunes
Once the fix is in place you can now open iTunes again. You will notice that all of your playlists, music and other items have vanished. In order to recover them all (with the exception of the Smart Playlists mentioned in the About the Workaround section above) we'll need to import the hacked Library XML file back into iTunes.
1. Open iTunes and press CtrlShiftO or go to File > Import…
2. Navigate to and Open your modified Library XML (as pictured below).
3. iTunes will then begin importing the contents of the XML file (as pictured below).
Note: This process may take a while, depending on the size if your library.
Wrapping Up
Once the import process is complete iTunes will look almost exactly the way you left it, with the exception that some playlists have been duplicated and the number of songs may be a hair off. To fix this problem delete any duplicate playlists in the "Library" panel in iTunes. You can now test out the changes by selecting an item moved earlier and testing it out. All that's left from there is to let iTunes perform any automated analysis it needs to do and rock on.
Other OSHoly Smokes:
I appreciate your detailed workaround post. My question is this: I use iTunes to keep everything organized (though I'm well aware of the shortcomings...) and can use the simple solution that Chris from CA posted, but I don't have room to consolidate everything. My read on consolidating is that you copy from wherever you have your music located (and right now my music is outside of the MyMusic/iTunes folder, as that backs up to my work server) and so you have to have enough room for all of your music to be copied (and then you delete it from its prior location). That's how Apple describes it in, e.g., http://docs.info.apple.com/article.html?artnum=301748. I ain't go that kind of room. Is there any way to make the move to a completely different PC by following the simple option? From the posting I just linked it sounds like you MUST consolidate whether you use you iPod to move things or use an external drive.
Of course, I can use your workaround, but I thought I'd ask first. Many thanks.

Hanging start up and other oddities
Hanging Startup and other oddities
I'm not especially proficient with the upkeep and terminology that comes with the programming aspect of Macs, so, if you do help, if you could please put whatever advice you have in lay terms, it would really help me out.
I've had my laptop computer for going on three years now, and I've never had a problem like this before. My machine started to really slow down yesterday morning, and generally when ever it does that, I just do a quick restart, and everything is back at normal. Well, not so yesterday.
To begin with, it took me to the grey screen, and it just stayed there for about ten minuets. It didn't change, didn't move to load the apple insignia, nothing. So I gave it a forced restart, and it did it again, except it load the apple logo.
Third time, it got me to blue screen. On restart #4 (force restart #3), it finally loads into my desk top, but the slow processing remained. I tried to go in and repair disk permissions, but then it froze up, and I forced a restart. This time, back to the grey screen.
I lost count as to how many time I restarted, but I finally went and rooted out my OS disks, and did a restart with disk 1 in, holding down PR+CtrlApple (It was my understanding that this would zap the P-Ram, and would at lest sort of help with whatever my problem was). Well, it took me to grey screen, but now a small folder is in the center of my screen. going from the finder icon to a "?" in the middle of the folder.
Did a restart holding down the "C" key, and it went into the install screen that launches from the disk. I was able to click through to select the drive I wanted, then my hard drive didn't show up as a possible selection. Yet ANOTHER C key restart, and this time it showed up.
Went through the first loading screen, where it is checking permissions, and everything's fine, but when I get to the installation process, it tells me there is an error with my perimeters, and I should restart and try again. Did this again, and I had to start over from square one.
I tried just a normal restart after three or four attempts at an installation, and now, whenever I load it without C depressed, a grey box shows up in the middle of my screen with an image of the globe on it, and it flashes. Nothing else loads until I do a restart.
It's my impression this, obviously, isn't a good sign and I should get in contact with someone who knows what they're doing and can walk me through it and get my computer running again. I thought I'd run it by you guys here before I called Apple, and, hopefully, you guys can help me out/help me better describe my problem. Any help you can give - links to other threads, experiences, what something means, what to tell a technician that I'm looking at/going through, anything at all, will help me tremendously.
Thanks for your help and time,
Brittany
Powerbook G4 Mac OS X (10.3.9) Owned Since April, 2004Hey Gary, thanks for the welcome!
By the time I was able to pull your suggestions off of the form, I had already done a few things to my computer, as per recommended by the Apple site. This article is what I was pulling my steps off of.
I started at step 4 (Selecting the "Connect automatically when starting TCP/IP applications") and went through to step 8, semi-step i.
1 - I tried to start up in safe mode (Shift+Restart) and I logged several kernal panic screens before I even got to the apple insignia on a grey screen.
2 - I ran Disk Utility several times, and would come up with an error and a notice that the utility had quit. The first time I ran it, I noticed that it had found a lot of Oprhaned indirect iNodes, and by the second time the utility was ran, they no longer showed up in the right pane of the box. The fifth time it ran, it took roughly two hours to complete, and actually went all the way through.
3 - Still would not load past the grey screen, so I went through and did fsck check a couple of times, and it told me that my machine appeared to be ok. I got all the way through the step where it tells you to run a fsck, then type in a mv Preferences Preferences_old, then did a reboot and let my computer load.
When it finally did load (the actual boot up and load took about ten minuets, which is about seven minuets slower than normal), it took forever to do any commands that I issued. I went through and backed up all of my files onto my external, and then I went to go follow the rest of the step, and my computer froze up. I decided to save the rest of the procedure for today, when I can find some time.
The basic thing that I'm concerned about now is that the machine is running exceptionally slow. It loaded Safari and a couple of other applications I'm always in, but it took roughly ten times longer than normal to do anything.
Since it's recignising the machine and loading into my desktop, I was going to see if I can now do a safe restart and see if I can follow any of the steps that are dictated by the site, but I'm still not certian if that will work. Last time I tried it, I got a kernal panic screen.
Anything I should try?

Why does itunes and other media continue to play when i close the lid on my macbook pro 2011???
Hey, I am new to mac and still getting used to it (making the transition from windows), its amazing! Anyhow, I cannot figure out why my itunes and other media like youtube or a film on vlc player continues to play once the lid has been closed. I thought that when i close the lid the macbook should then sleep. It does everytime when there is nothing playing. The little white light on the bottom right hand corner of the book is on but music continues to play.
The sleep option always works. If I press the power button and choose the option sleep it does so etcc.
Is this normal and am I just being stupid or is there a problem??
I bought the laptop from ebay, its a macbook pro late 2011 17inch. I dont have apple support and might have to make a trip into London to the mac store however I was hoping someone can help me...
Processor 2.4 GHz Intel Core i7
Memory 4 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
Software Mac OS X Lion 10.7.5 (11G63)
Thanks if you can it is muc appreciated....!!hey, thanks for the reply. I don't know to be perfectly honest. When I close the lid without any music playing it sleeps fine. How could I check?
So basically I pressed the power button and pressed sleep. The laptop turned off and the little white light turned on no problem. I did the same thing with closing the lid and it went to sleep no problem. (Can you confirm that when the little white light is on it means the laptop is sleeping)??.
I then had itunes playing and pressed the power button and when i pressed sleep the music paused then 6 seconds later it went to sleep. I then had itunes playing and closed the lid and the music kept on playing even though the white light was on.

My iPhone 5s on ios 8.1.2 is stuck at Apple logo or recovery mode.. To fix this issue, i need to update it to ios 8.2 through itunes.. I want to ask that my data i.e. Photos and other personal data would be removed after updating it or not..?
if yes then how can i save my data or get out of recovery mode.. Is there any safe mode or something like that on which i could access my data..
P.S. I have not taken any backup of my iPhone on itunes..
Please help me sort out this issue..Recovery mode doesn't mean that all your data is already lost. You only lose your data if you restore it.
When you plug the phone is into iTunes hold down the home button. iTunes may then give you the option JUST to update the software first. This should not get rid of any data.
However, if iTunes is only giving you the option to RESTORE and update, then you will lose your data I'm afraid.
Hope that helps! -

In Adobe Flash CS6, I have a blue box appearing around lines drawn with the line tool (and other tools like brush etc). Whenever I try to use a tool, a blue box appears around the line and I have to double click it to manipulate it, which opens just that line in a semi burred screen where all the other objects are semi-grey in the background. I can manipulate this line in this screen but nothing else at that time which I could do about 5 minutes ago. For exampe, I no longer can join up 2 lines drawn by the line tool together. For some reason this started randomly (probably due to a accidental shortcut combination) and I just can't put it back to what it used to be. I have inserted a video hopefully showing what I mean. Any help would be appreciated.

Trying to move my iTunes Music and other media from the main drive on my pc to an external hard drive but iTunes is not recognizing the new file location? Ideas?
Hello there, Underwriter.
The following Knowledge Base article provides in-depth instructions on how to migrate your content to an external drive:
iTunes: How to move your music to a new computer
http://support.apple.com/kb/ht4527
Particularly of note for your situation:
External drive
This option requires more work than Home Sharing, but it creates a backup of your iTunes library on the external drive in addition to moving your content.
Notes before you start:
You can use most iPods as an external drive.
Windows operating systems don't recognize Mac OS-formatted disks (HFS or HFS Plus formats). Because of this, you can't use a Mac-formatted iPod or external drive to move your music to a Windows PC. See iPod: How to determine iPod's hard disk format if you're not sure how your iPod is formatted.
Mac OS X can read Windows-formatted iPods and drives. This means there are many ways to migrate your information from your old Windows-based PC to your new Mac.
Mac OS X: To be sure external drives appear on your desktop, choose Preferences from the Finder menu. Be sure the options for "External disks" and "Hard disks" are enabled.
Part 1: Locating and consolidating the iTunes Media folder
Part 2: Copy iTunes folder from the old computer:
Part 3: Get iTunes ready on your new computer
Part 4: Back up any music that's already on your new computer
Part 5: Copy music to your new computer
Part 6: Add preexisting music that was on the new computer back into the library
Thanks for reaching out to Apple Support Communities.
