Undo Data preferences
I read somewhere that there is a preference that erases your undo data when you quit your project.I have tried looking for this but can not find it,could someone give me a little help please? Many thanks
Preferences>Audio>Sample Editor tab
Don't use it myself, but its location suggests it only applies to the .. you guessed it.
I should add that just automatically erasing all the undo data for the project is a new unchangeable behavior in L9.

Hi all, my harddisk is almost full and I want to make some space.
I found out there's a folder which contained 15 Gbyte of Undo data...
It is located over here:
Application Support/Logic/Undo/Undo Data
What does Logic do with it? Can I erase the data?
Hope someone can help me.....Sounds like you never set your preferences in Logic to Delete Undo History when quitting. So all the undo data from as long as you have been working in Logic 7 has accumulated.
Chances are, that much, if not most of that, is undo data for songs you probably have long since finished.
If you don't have any need or desire to revisit any of those songs, or more importantly, think that you would possibly need or want to undo any edits made way back when, then yes, go ahead and delete the contents of that folder.
And when you get a chance, change that preference in Logic, so that when you quit the song for the day, your undo history is cleared. That will help keep this from happening again, over time. -
Buffer busy waits on UNDO data in Active Dataguard
Oracle Version: 11.1.0.7.0
Active Dataguard
Statspack has been configured for Active Dataguard on Primary database.
We got an spike of Buffer busy waits for about 5 min in Active Dataguard, this was causing worse Application SQL's response time during this 5 min window.
Below is what i got from statspack report for one hour

Could any one please shed some lights on finding the reason for this issue ?It's been interesting, The job runs only on ADG?
Even it is only reporting purposes, Which runs only select statements. Are you sure that issue is only because of this job?
Moreover am interested to know, How you able to monitor at the same time? Using EM?
What all are the jobs ran on primary at the same time?
Then, is it possible to run the job on primary and see whats the response?
I suggest you to run the same job again on standby and see the ET of the job and also gather the statspack to check whether you got same buffer busy waits or not.
What storage you are using for primary and standby? In terms of I/O and performance all are same?
You got chance to take statspack even on primary database?
What are the parameters differ in primary and standby?

Does UNDO data persist after a bounce ?
RDBMS Version : 11.2, 10.2
Platform : Unix
Will Oracle retain the Undo data in UNDO tablespace after a bounce ? If yes, why does oracle want to retain UNDO data which was present before the shutdown ? Is there a way to verify that UNDO data is retained after the bounce ?Hi
It is probably better to understand the difference between undo and a transaction.
1. Undo data (more accurately undo records) - means undo records stored in the undo blocks of an undo tablespace. Retention of those undo records are controlled by undo_retention parameter (and also by auto undo retention tuning feature). Even if you restart the database, those undo records are still kept in undo tablespace (meaning, undo tablespace is not cleaned out); These undo records are used during Consistent Read copy generation and transaction rollback as discussed in (2) below.
2. Transactions - Shutdown immediate kills the sessions and rolls back active transactions; shutdown transactional will wait for the transaction to complete, but kills the session after completion of current active transaction ; shutdown normal will wait for the session to complete (and so transactions to complete); shutdown abort will kill the session, but does not roll back active transactions.

Need to undo email preferences
When our Yahoo email account was hacked, we changed the password and added a new Gmail account to have as an alternate. When we set up the new Gmail account, there was an option to send all Yahoo messages to the new Gmail account. We want to undo this preference but can't figure out how. Please advise.
sounds like something you should setup in your yahoo mail settings on their webpage

Can you transfer apps data/preference settings from one iPod to another?
I just bought a new 32G iPod touch (previously using a 16G touch). I know how to transfer all of my music, movies, etc. from the iTunes library.
But here is my question: is there a way to transfer the "preferences/settings" files for my apps--workout routines, high score settings, mail settings, stock data--from the iPod itself?
The actual apps transferred over fine from iTunes, but is there a way to get all of my info from my old iPod to the new one?I am trying to do this, but it doesn't seem to work for me. When I restore my new iPod from my old iPod backup, I only get settings and some pictures, but no apps or music.
In order for this to work would have I had to have the "Sync" settings on for apps and music? I can't turn this on now. The music is not a big deal, but I have a few essential apps on here that I really need the data from.
Any ideas? -
Date preferences problem - Photoshop CS2 and OS X 10.4.6
I am running Photoshop CS2 9.0.1 on two Mac G5s (Mac OS X 10.4.6) and Photoshop CS 8.0 on a Mac G4 (Mac OS X 10.4.6) but now have a problem with the correct display of dates in File Info on the pair of G5s running CS2 9.0.1.
However I configure the date display preferences in International in System Preferences (UK prefs - DD/MM/YYYY) File Info will now only display the date as 'short', i.e. 1/6/06, for example. Naturally this presents a major problem with all my pre-2000 dates. By contrast, with exactly identical System Preferences on the G4 with Photoshop CS, the dates display correctly, i.e. 01/06/2006 or 06/06/1944. One of the G5s also has Photoshop CS 8.0 and also exhibits the same problem.
Is this an OS X 10.4.6 update problem, as I believe, or a combination of flaws between Apple and Adobe? Is there a cure? With a vast number of images in a picture library it is essential to have accurate, pre-2000, dates embedded in the File Info metadata. Can anyone offer an answer, a solution or a workaround?After much trial and error I eventually discovered a fix. When customizing the Date Format Preferences (UK) (in System Preferences/International) select 'Short' and then drag the day of the week from the list below as the first item in the displayed date; i.e. Thursday 08/06/2006
Then modify the DD, MM and YYYY by highlighting the numbers and selecting the full 2 or 4 number digit from the drop-down menus. This is something that seemed to be fine in 10.4.5 but has changed in 10.4.6! -
Time and date preferences crashing
Hi. Every time I click on the clock on the menu bar and go down the menu and click on "Open Time and Date...", it never works. It always stalls System Prefences, although it will occasionally open after not responding for a minute or two. This has only started happening recently, although I can't pinpoint any event that might be causing it.
-EricEric
Usually a preference pane problem can be fixed by trashing
com.apple.preferencepanes.cache in Home > Library > Caches folderIf this alone doesn't fix things after a logout/login, then trash it again (because it will have regenerated another bad file), together with
com.apple.systempreferences.plist in Home > Library > Preferences folder,
and in the Home > Library > Preferences > ByHost folder, the two files: com.apple.systempreferences.xxxxxx.plist and com.apple.PrefPane.Network.xxxxxx.plist, where xxxxxx = a hexadecimal numeric string.Post back to say if this works. -
Non Archivelog Database- Undo Data files Deleted-How to Open Database ??
I am doing some test in Lab server.
Unforunately Undo Tablespace datafiles are deleted from the server.
Database is running in No archivelog Mode and I don't have any any type of Backup.
Last one week, i was doing only read only work with database. So Not really concern how much i will loose.
The biggest worry is How can I open the database with existing datafiles ????
Regards ,
Sumit
Edited by: Sumit2 on Aug 27, 2009 12:57 PMIf any active transaction or data needed by any of the session for rollback then it will be difficult to recover those transaction and your database data will be in inconsistent state. As you were doing only read only activity you can safely recover the database.
just comment undo tablespace and undomanagement parameters init.ora file and restart the database.
Once database is up create new undo tablespace and assigning it as default undo tablesapce tablespace. -
Dbwr and writing undo data block
hi guys,
If dbwr was to write a dirty block to disk, would it also have to write the dirty uno data block that contains the before value of our database block to disk too?
ThanksOracleGuy777 wrote:

The first thing to remember is that recovery depends on the REDO, not the UNDO, so technilcally it doesn't matter whether dbwr manages to write neither, one, or both of the two blocks to disc to avoid any problems with crash recovery. This should give you a clue that dbwr doesn't HAVE to write the undo block at the same time as the data block.
In practice, it is possible that both blocks will be written virtually simultaneously because the two blocks will have been modified at the same instant and therefore could be written during the same 3-second timeout write (continuous checkpoint). It is also possible, though, for the undo block to be written some time before the data block, or some time after the data block - it all depends on what activity has been going at about the same time.

I had scanned a bunch of old photos and was changing the dates in order to get them properly organized. But I must have somehow hit 'select all' before I did batch change, because now every single one of the 7,500 photos in my library is dated 12/2/1984. Is there any way I can undo this? Even just going back to the original date stamp would fine. I want to cry.
As far as I can tell, changing the date actually changes the underlying EXIF data<<<</div>
No. If you do a "Get Info > Photo" you'll find that the original date is still present. I did some experimenting. One solution is to export the photos and import them back into iPhoto. That will put the original date back. With the volume that you have, it might make sense to export to specially-named folders and then delete from iPhoto before you import back in. -
Syncing/mirroring data/preferences/apps between macbook pro and air
This was probably already asked hundreds of times – but after extensive google search I still haven't found a solution that would satisfy me;
It is about syncing ...
To be more precise: I work on two macs (in my case a macbook pro and a macbook air) and I want to have kind of "mirrored systems";
I want to have the same apps across the two systems with the same preferences
And of course I don't want to set it up all manually.
And programs who use librarys to manage the underlying data (like iPhoto, Together, iTunes etc.) should be synced across the two macs.
Is that even possible?
I tried the dropbox solution for application preferences (copying the preference-files to dropbox and create simlinks in the preference folders).
But it seemed like this would lead dropbox to constantly uploading and syncing stuff (which is not necessary since I don't work on the two machines 'simultaneously') ...
Also it feels like a hacky solution which at some point could easily break.
So I thought about time machine.
But I heard that it is really slow – and I only have 128 gb on my macbook air.
Therefore I actually don't want to sync every application and every data-folder.
So what is the best solution for these problems?
Is time machine really so slow? Can't you tell the macbook air to only 'restore' part of the newest backup (made on the pro)?
What other solutions are there?
I use the macbook air when I have to travel – so I don't need a perfect sync constantly – but before I leave the house with the air I want to get it synced properly (but as I said, not everything because it wouldn't fit on the ssd of the air) ...Yes. You can use File Sharing between the two computers together with an appropriate backup/sync utility.

How to undo data upload in BPC
Hi All,
I have inadvertently uploaded "Actual" data file in BPC with the wrong year, i.e. the Actuals data file should have 2008 as the year, but instead it has 2009 as the year.
Please suggest what would be the best way to fix it.
Is there any way to delete Transactions data in BPC?
I also tried to look the option of using journal for fixing this issue, but every time I try to open an existing or new journal, I get the message that I do not have any authorization for this module.
I am working in a sandbox /Demo enviornment with only one user, and that user is the Primary Admin/System Admin and has all accesses.
Can anyone throw some light as to why I might be getting this error message.
Thanks in advance.
Best Regards.Hi Anurag,
For deleting the existing data goto datamanger-Run datamanger- select clear function from data manager package.
Delete your existing data based upon the parameters.
Incase of journal posting you dont have sutorizatiion, check Task profile in your security settings.
Ensure creation of journal wizard before going forward the journal.
For your current issue journal posting is not correct option.

Date set up is for UK (day/month/year), whichever format I use for cells in Numbers, it's aways MM leading.
I tried everything on 2 separate machines and it's not working on both. What am I doing wrong ?Mirage.za,
You could try using a Custom Format.

Data (Preferences, Passwords, Bookmarks, etc.) Loss
I recently installed Image Browser version 6.0.1.37, which came with my new Canon PowerShot G9 camera. It seemed to be working fine until I started to browse images in other folders on my desktop. The app stopped responding. I finally used Force-Quit to close the app and restarted my computer. When I opened it, my desktop was gone. It was as if the computer were being opened up for the first time. All the customization I had done was gone, as well as all the folders I had on my desktop. Passwords, server information, preferences, etc; in programs like Apple Mail and my DSL setup were gone and all the addesses in Address Book. If I search for folders that were on my desktop using FIND, I can find them and if I look at the path and click on the desktop folder, I see all the stuff that was originally on my desktop, but they don't appear on the desktop. Any suggestions of how to restore my original settings? Any ideas about what might have happened to cause this problem.
