After a system crash, everything has been scrambled. I'm now trying to
rebuild it. I'm still on PSE 4.0, so perhaps my setup is too primitive for
my question -- but I'll try:
It does appear that I have been able to salvage most of the Tag and Collection
structures of the Catalog from an older backup, but there are a lot of
pictures still missing.
So my question is: If I do a "GET" of a folder of pictures, (I have many such folders) is there some feature (or some way), within
Photoshop, to prevent it from accepting another copy of the same exact photo that it already has in its database"? (My presumption is that there will be some pictures in that folder that have already been put into the Organizer, and some that have not -- I only want the ones that are not already in there.) If there were just a few pictures, I could handle this manually. But I have many hundreds, if not thousands.
Thank you very much for any guidance,PSE has duplicate detection feature. While you import the photos if these are alredy there in database, these won't be reimported and the same would be prompted by a message.

Strategies for post-crash recovery?
After a freeze, forced reboot, and 48 hours with TechTool and DiskWarrior (worth every penny of the $80), I have my computer back. DiskWarrior was able to rescue files, but they're in a "rescued files folder." Some things aren't exactly working well. Spotlight can't find anything.
My question is what is the best strategy to recover full functionality after a crash like this? Should I wipe the disk and re-install. Or re-install over the current operating system?
Also, I have orphaned mail messages that I'd like to put back into mail. Is there an easy way to get them into a mailbox so I can sort them?
One of my iPhoto libraries disintegrated. I have the .jpgs, but am not sure how to put it all back together.
Any tips or suggestions?Personally I would back up my data and then format the HD and re-install. Also zero all data (which helps if you have bad sectors on the HD). Then re-import your data.

ITunes 10.4 crashing when syncing music
I'm having a major problem after upgrading to iTunes 10.4 for Windows. I'm now randomly crashing when syncing music to my Ipad 2. It seems some sync fine and then all the sudden it crashes.
The crash I'm getting is:
AppName: itunes.exe AppVer: 10.4.0.80 ModName: quicktime.qts
ModVer: 7.69.80.9 Offset: 001cd746
What's odd is that it's even crashing on audio podcasts that I downloaded on my iPad 2 which are being synced to my PC without issue, but then cause it to crash when syncing back.
I had no problems with 10.3.1 or earlier.This is long, jump to the end if you don’t care about my new life problem! And sorry for my English, I’m not a native English speaker! Also, I’m just posting this stuff so people with this issue don’t have to try it all also.
ok, so my problem started with the ipad 2; i had a lot of pictures there but wanted to change the "stupid" way (for a windows addict) that apple arranges, or not, folders hierarchy. I deleted every single picture and imported my new structure (in windows). Useless to say that i got stuck here. i tried 100 times and i got the quicktime.qts module error (iTunes crashing). Good to know, obv, but what do i know of quicktime!? nothing...
Since i have an iPhone 4, and the iPhone only ever carried pictures taken with it, never had synced pictures before i decided to give it a try. same error…Ok, now i know the problem isn't in the devices but in iTunes itself, Quicktime, most likely.
Not happy with this conclusion, i decided to restore factory settings on both ipad 2 and iPhone 4 (4.3.5 ios). Gave it another try, after deleting every ipod photo cache folder in my library and re-installing iTunes completely (i tried re-installing before devices restoring with same error). No luck here either...
Went to discussion boards and figured a lot of people are having this issue, so i thought it’s probably in the iTunes 10.4 update, since i didn’t have a backup of my previous library, and i have 20000 songs, and didn’t want to lose the only library i had, i opted not to install previous iTunes version because i knew my library wouldn’t work and i rather have a decent library with no videos, than videos with a new library to build. So I didn’t try this.
i tried everything, there's a post that a guy, a while ago, resolved this issue (or similar) simply by deauthorizing and reauthorizing computer, or just by logging in to his iTunes account... other person resolved his issue by logging on a new windows account and syncing with a "clean" iTunes then moving to his previous account. Or deleting some quicktime files and folders that are on system32 folder, besides the 2 files that are needed... i only had the 2 needed files, no more! I tried it all, no luck.
Somewhere i read it could have to do with quicktime not being the default video player for .mov files, so i made it, still no luck.
My last try was messing with the registry looking for "stupid leftovers" of quicktime, a lot of them i knew shouldn’t be there and i deleted, but i was still stuck on the crash error. for this i removed iTunes, cleaned computer from apple stuff (all but my library files that i backed up),
cleaned registry and installed everything back again.in the meanwhile, no sure when, i figured since this could have something to do with quicktime (i noticed that it gets stuck when starting to optimize videos), i created a test folder with one picture and 1 video and I managed to pass through optimizing process. tried with 3 movies, after emptying the device and deleting cache folder (like from scratch), but Kabooom, crashed again. tried same thing, but first i opened the movies in quicktime in windows, then synced and it worked!! probably this could be the solution, tried with my whole library (2k+ photos and about 100 movies) but crashed again... probably i forgot/messed up to open some movie in quicktimes pior to syncing, but well, i was fed up with .mov files, or .mp4, m4v, FWIW (i tried them all).
After this (i only did all this because I’m computer addicted!) i rested my case, i posted on the forums and had 2 choices: wait for apple to solve this, if they care or Format my PC and probably be getting the same error, this is the only thing i didn't try cause i have lots of stuff to backup and configure, and lots of onetime license software...
I kept doing stuff with computer, installed a bunch of software (not related to this but related to DVD and movie editing stuff), after i stopped working i retried again, Meh, cleaned everything and got thru once with my new test folder (with different videos and pictures), but when i went to my REAL folders, APPCRASH again. Broke my mouse (apple owes me this!), stopped working and went to sleep.
I was real convinced this could have something to do with video encoding/decoding stuff. And also about quicktime
Now, the only thing working for me was:
Opening movies in quicktime prior to syncing (worked once or twice)
syncing right after I turned on the computer, but only small folders.
Makes me think problem is in the processor, since it eats a lot of CPU and memory at the end of a 1000 picture and videos sync. And it crashes when starting to optimize videos, sometimes I see it passes like 2 or 3 movies and crashes after. That’s why I can sync small folders right after I turn on my computer, but with big folders itunes just lags my windows wayyyy to much and at the end (when gets to optimizing videos) is really hot and slow, and crashes, I could make 1 video at a time but I believe itunes should work for itself without these “workarounds”.
I’m a computer guy and an application that uses up almost all computer CPU when “working” and “eats” way too much RAM is not a solid application… in this part itunes *****. -
ITunes crashes upon syncing music to iPhone 3GS iOS4
I recently bought an iPhone 3GS and upgraded it to 4.1. Whenever I try and sync my music, iTunes will crash - I get the "iTunes has encountered an unexpected error and has to close" message, with the Windows report screen popping up and all that. This is only when I sync my music - applications and contacts sync fine (I do not sync videos/photos/voicemails so I have those all unchecked). I only sync one selected playlist (not my whole library).
I am using iTunes 10, running on Windows XP. I have uninstalled and reinstalled numerous times (including downgrading to 9.2 at one point) but I continue to get the same result - iTunes crashes upon syncing music. I just did a fresh restore, and this has not fixed the problem.
I have tried splitting up my 550 song playlist that I normally sync to my iPhone, but when I did this (it was only about 250 songs) iTunes crashed again towards the end. It has been crashing whether or not I have the "Convert to 128 kbps AAC" checked or not. It crashes somewhere in the middle of "Copying X out of X."
Note As of typing this, I successfully synced a separate 58-song playlist WITH "Convert to 128 kbps AAC checked." However, I then tried to sync a different 61-song playlist WITHOUT that checked and iTunes proceeded to crash. After this, I tried syncing the 58-song playlist again WITHOUT the Convert checked and it synced perfectly without crashing.
Recap:
Playlist #1 (550 songs) - Crashes WITH OR WITHOUT convert checked
Playlist #2 (58 songs) - Syncs perfectly with or without convert checked
Playlist #3 (61 songs) - Crashes without "Convert..." checked (have not tested with "Convert..." checked, it's late and I have to head to bed soon and I want to get this post up).
Considering this information, would it be reasonable for me to assume that it's some of the songs in my library that are making iTunes crash? If so, how the heck am I supposed to figure which songs are causing this? I really hope I do not have to sit here as iTunes syncs and watch our for every song it crashes on...
Does anyone have any suggestions? I've scoured these boards but I haven't found anyone with the same situation as me, and thus no answers.
So frustrated. Even my old iPhone 2G on OS 3.0 syncs my music perfectly!!I am back to attempting to sync my music. iTunes continues to crash on certain songs, however I have also noticed another problem - each time I attempt to sync my main playlist (after deleting the song it crashed on last time), it will say Copying X out of like, 96 or some number that is nowhere near the real count of songs on the playlist.

* You changed the page that comes up after a crash - the one which shows the windows and pages that were up before the
crash.
This used to be a real HTML page and it isn't any more. THis choice was pure isiocy consider how peopel used that page every day (try taking to your users for a change).
The pages listed on that 'post crash page' used to be actual LINKS (you could right click them &
manually open them in another tab - and most peope DID that every day). You could also (and I did this a lot) drag a second
copy of the page, into a new tab (to keep track of all the pages I had not wanted to open)
Now the pages are no longer links. You cannot right-click them.
The thing in the probser is no longer a page that I can drag into a new tab.
Roll the version back and throw this one in the bin...and have a good long talk with your developers about the definition of
'STUPIDITIY'
Then I try to type anything in the addres bar it is suppose to repoond with the history of old things I have types in the past, or
search for what I type (and in some cases I think it tyes to convert it intoa URL). However it no longer does any of these
things. When I type in the ADDRESS BAR ONLY, I do not get all of my letters to appear. I have to type into a notepad or
into the search and to copy and paste to go to a URL. Nothing that is typed into the address bad responds normally at all
anymore, and I am fairly certain there are no new addons on this machine at all. It does not matter which things I disable. It
still does this. W of course points the finger back at a change to FIREFOX. I wich I could just sitct with one stable release
forever but the MOZILLA folk thing it is best to force peopel awy from a working broswer release to a horrible one (due to it
being out of date).
FIREFOX 26.0 has 'issues' (ie new *features*/bugs)
1) History is no longer accurate. My Proof? This machine is the primary one for the entire family (the only PC working). It is
logged in with same user every time and never has its history cleared. It now January 7 so I ought to have a list of all of last
months browing available to me.
However, according to FIREFOX history, in all of December 2013, the entire family only went to 51 primary URL's. None of
the official TV sites I use to get episodes are listed. None of the official movie sites I use are listed. The primary URL for
ebay is not listed. Only 1 out of our 4 weather sites that I use (at least once a week) are listed. Only 1 of our 3 FINANCE
sites is listed. There ought to be several; hundred root URLs listed.
Please fix history as this change seriously "blows greasy chunks"
PROBLEM (a stupid change in the new FIREFOX version)
FOr a long time, after a crash you got a useful page (a real HTML page) which gave you a list of all of your last sessions
'winwos and tabs' that were open when the browser crashed. there were certain ways of using this page that are no longer
able to be done.
The old method was wonderful as it had this behavior :
*** The old method for displaying your 'Recovered Tabs' allowed you to :
a) right click an individual item and open it in a tab without getting rid of that lovely window of your previous session of
'recovered windows and tabs '.
2) drag the URL for the entire window of 'recovered windows and tabs ' to a new tab (to make a second copy) so that you
could select just a few of them to open as a group, and stil have the old list handy.
You can no longer do either of these things. The 'recovered windows and tabs ' page no longer has links in it and can no longer be dragged, so you cant select a few of them to use, and keep the rest around for later. NOW - once you choose which pages to open the window is gone forever (can can't get a second copy).
People used to make a copy of the page for later use (with a drag)
we also used to open pages with a right click (which no longer functions
This new method seriously blows big greasy chunks. A parge loss in function has occurred.
Put things back as they were. 26 is full of terrible changes that NOBODY likes. It also has a lot of bugs (history is not reliable at all)(1) Firefox's built-in post-crash page has not been a real HTML page for a long time (for example, from the time of Firefox 22, see: [https://support.mozilla.org/en-US/questions/968212 Want to save LOTS of versions of "Restore Session.xht" from the "oops ..." page for later use]). If you had this working differently with Firefox 25, that might have been created by an extension.
You can check to see whether extensions are disabled or need an update on the Add-ons page. Either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Extensions. The disabled extensions cluster toward the bottom of the list. To poll for updates, use the "gear" button above the list and choose Check for Updates.
If you used the Reset feature (or Firefox automatically did a reset due to some problem during upgrading), you will need to reinstall missing extensions. The reset feature creates a folder on the desktop named Old Firefox Data. Do you have that folder? There may be data you can recover from it.
(2) There are many ways for history to get cleared, both internal to Firefox and external. Could you double-check your Privacy settings?
orange Firefox button (or Tools menu) > Options > Privacy
* The "Firefox will" drop-down says Remember History: Firefox shouldn't be clearing history, but an add-on or external software could do it
* The "Firefox will" drop-down says Use custom settings for history: inspect the "Clear history when Firefox closes" setting to make Firefox isn't set to clear history. Also check your add-ons and consider external software.
Firefox normally accumulates months of history. However, some of Firefox's database sizes are based on disk space available. If your hard drive is very full, Firefox might reduce the amount of history stored. -
Itunes crashes when importing Music File or Folder ever since i updated it yesterday
You can try downloading 7-Zip (free), or a free trial of WinRAR, and unpack the iTunesSetup.exe or iTunesSetup64.exe file into its components then try installing them individually in alphabetical order (don't try to install SetupAdmin.exe or iCloud.msi). You may get a more useful error message as to which component has problems.

When occurs crash recovery,why use active online redo log not archived log?
If current redo log had archived, but it's still 'ACTIVE'. As we all know, archived log is just an archived copy of the current redo log which is still 'ACTIVE', they have the same data. But why use active online redo log not archived log for crash recovery?(I think, if crash recovery can use archived log, then whether the online redo log is 'ACTIVE' or not, it can be overwritten)
Quote:
Re: v$log : How redo log file can have a status ACTIVE and be already archived?
Hemant K Chitale
If your instance crashes, Oracle attempts Instance Recovery -- reading from the Online Redo Logs. It doesn't need ArchiveLogs for Instance Recovery.
TanelPoder
Whether the log is already archived or not doesn't matter here, when the instance crashes, Oracle needs some blocks from that redolog. Archivelog is just an archived copy of the redolog, so you could use either the online or achive log for the recovery, it's the same data in there (Oracle reads the log/archivelog file header when it tries to use it for recovery and validates whether it contains the changes (RBA range) in it what it needs).Aman.... wrote:
John,
Are you sure that the instance recovery (not the media recovery) would be using the archived redo logs? Since the only thing that would be lost is the isntance, there wouldn't be any archived redo log generated from the Current redo log and the previous archived redo logs, would be already checkpointed to the data file, IMHO archived redo logs won't participate in the instance recovery process. Yep, shall watch the video but tomorrow .
Regards
Aman....
That's what I said. Or meant to say. If Oracle used archivelogs for instance recovery, it would not be possible to recover in noarchive log mode. So recovery relies exclusively on the online log.
Sorry I wasted your time, I'll try to be less ambiguous in future -
Crash recovery of productive db very slow
We had to shutdown a productive database with db2_kill, because it couldn't be stopped normally and had problem with a full FAILARCHPATH (After TSM server had problems, the archiving to TSM has not been successfully any more, even after TSM Server was up again: We had this problems before....)
The crash recovery takes very long. Sometimes even db2 list utilities <show details> seems to hang.
With db2pd -everything I can see the progress of the crash recovery:
Database Partition 0 -- Database PC1 -- Active -- Up 0 days 01:57:14 -- Date 05/07/2008 11:34:59

So the db has now finished approx 1/3 of the bytes of the forward phase and then also have the backward phase!
In the db2diag.log there are no more entries after beginning of the crash recovery of 09:38.
We have move one logfile from the FAILARCHPATH directory (which was 100% full) to a different directory to be sure, that the slow crash recovery has nothing to do with the full FAILARCHPATH.
The log_dir directory has 20 logfiles (LOGPRIMARY+ LOGSECOND) in it (more could not be allocated there because the log_dir is sized according to the LOG-Parameters)
Parameter UTIL_HEAP_SZ = 150.000
Does anybody have an idea, why the crash recovery is so slow ?
Kind regards,
UtaHello Ralph,
the needed logfiles were all there and we didn't need to restore any logfiles from tsm (the "active" logfiles, which are needed for crash recovery should always reside in the log_dir...)
At 2008-05-07-14.17.07.357544 crash recovery was completed successfully.
At 2008-05-07-13.56.41.297552 the db has started archiving to tsm again:
ADM1844I Started archive for log file "S0003329.LOG".
According to dba collegues the crash recovery were only 50 % finished and then suddenly everything was finished. Since the "db2 list utilities" takes forward and backward phase into account for percentage, I assume that the backward phase was very fast.
The dba collegues have also recognized, that in the log_dir there were logfiles which were archived to tsm already. So they moved them out of the log_dir, and additional logfiles could be allocated (Before no add. logfile could be allocated). I couldn't say, if this was the reason, why the recovery was finished then afterwards.
The only problem is, that the database doesn't want to archive Logfiles S0003329- S0003350. Strange is also, that logfile 3329 was archived to the FAILARCHPATH yesterday successfully,

Crash recovery: recreating invalid indexes
I want to discuss a phaenomen, which we often have saw during crash recoveries:
The "startsap db" is hanging, because after the crash recocvery itself is completed (according to db2diag.log), the connection to the database ist still hanging because the database recreate invalid indexes.
sf503:db2p02 10% db2 list utilities
ID = 2
Type = RESTART RECREATE INDEX
Database Name = P02
Partition Number = 0
Description = Recreating Invalid Index Objects
Start Time = 05/08/2007 09:37:42.721072
Sometimes this can take up to 25 minutes until this is finished and the connect is finished.
The strange thing is:
If a 2. connection to the database is made during "recreating indexes", this 2. connection is successfull and selects from t000 are successfull.
So, it is possible to execute "startsap r3" while the first connection is still blocked with recreating indexes.
I don't understand this behaviour:
- If the database really needs the recreation of invalid index objects for sucessfull database operation, then it should block ALL connections and not only the first one.
- If it's not urgently necessary, the database should done the recreating indexes in background and not block the first connection.
Also in the Recovery& High Availibility IBM Handbook I have nothing found about the "recreating invalid index objects"-feature.
Kind regards
UtaHello Jens,
thanks for the detailed answer!
As you wrote, the only workarond with changing db cfg parameter from "restart" to "access" needs some manual intervention if we don't want to risk the limit of maximum dialog runtime. So actually we will leave it as it is. We have a workaround with starting sap in a second window, when the crash recovery is finished according to db2diag.log and the 1. connection (startsap db) ist still recreating invalid indexes.
How can one determine the invalid indexes, who need recreation ?
Joachim: we don't have a real problem at our site. Fortunatelly we have crash recoveries only in the rare cases of system crashes, etc. So we are lucky not to have it every day....
Hopefully the behaviour will be changed to background index recreation in some later DB release. -
"cache recovery" vs "crash recovery" ?
Dear Friends ,
Would anybody plz tell me the difference between "cache recovery" and "crash recovery" in oracle ?
I search in google but dont get satisfactory answer ... ...shipon_97 wrote:

Crash recovery is done in two phase 1) Cache recovery 2) Transaction Recovery.
So crash recovery includes cache recovery.
Cache recovery means to apply redo log from log cache to the datafiles which may contain uncommitted transaction also.
These uncommitted transactions should be rolled back during crash recovery, and hence in transaction recovery it applied undo for all such uncommitted transaction.

Hello,
Who initiate the crash recovery? SMON process or any other process?
In the ealier version of oracle (Oracle 7.3), it was instance recovery,
Now in Oracle 9i there are two types of recovery one crash recovery and another is instance recovery.
I want to know that whether in prior to Oracle 9i, there were two such recovery or only one?
Thanks.crash recovery
The automatic application of online redo records to a database after either a single-instance database crashes or all instances of an Oracle Real Applications Cluster configuration crash. Crash recovery only requires redo from the online logs: archived redo logs are not required.
In crash recovery, an instance automatically recovers the database before opening it. In general, the first instance to open the database after a crash or SHUTDOWN ABORT automatically performs crash recovery.
instance recovery
In an Oracle Real Applications Cluster configuration, the application of redo data to an open database by an instance when this instance discovers that another instance has crashed.
Hope it helps.

my computer crashed saved the music in my music can ijust plug the ipod in and restor itunes
"has a back up of my music been created as i purchased them through itunes yet not plugged my ipone into my computer since purchasing the music?"
No. You would have to plug it in and transfer the purchases.
" all my music was on my old phone and not in my itunes library."
Why? This should never be the case. EVERYTHING on your iphone should always be on your computer and included in your regular backup of your computer.
You buy one and only one download. It is your responsibility to copy/move/backup your music.
You can try contacting itunes support and asking for an exception, but they are under no obligation to allow.

Crash recovery everytime starting an instance
Is it normal that a crash recovery is started every time I start
an Oracle instance on a WinNT 4.0 system.
The xxxALRT.log file contains messages like this:
alter database open
Beginning crash recovery of 1 threads
Thread recovery: start rolling forward thread 1
and so on ...
The database startup takes a long time but after that the db
works normal.Oracle always does recovery processing on startup. If you
shutdown abort your startup will take longer because there is
more recovery processing that has to be done. Shutting down
immediate takes longer because it performs clean up process so
that when you startup not as much recovery processing is needed.
