undo init and will redo it with more specifics next time
Property Changed:
flex/sdk/branches/gumbo_alpha/

It looks more cumbersome as every change will have to be executed 2 times. Which is not only more inefficient, but also more error prone.
So more reliable for the changes you wanted to make? I don't think so.
You should use the pfile as a backup only and start using the spfile.
This has several advantages
- You can change dynamic parameters both in memory and in the spfile at the same time, using the 'scope=both' clause of the alter system command
- You can change static parameters by using the 'scope=spfile' clause without having to shell out to the OS to edit the pfile
- You can restart the database from anywhere, so also from database control
- The spfile will be included automatically in your RMAN backup, so you won't loose it in the event of disaster,
You can easily conver the spfile to a pfile by using the create pfile from spfile command.
All of this is, of course, described in the Fabulous Manual.

  • What is the difference between undo tablespace and online redo log files.

    what is the difference between undo tablespace and online redo log files. I am confused
    as per my knowledge undo tablespace is used to store the undo information when a table is being updated so that, just incase we need to rollback a transaction we know what was present in the table earlier.
    when a transaction fails the SMON performs the rollback of the data.
    This undo data is stored in the undo tablespace and read consistency if any is enforced.
    is my understanding till here correct?
    Now, can this undo data/before image not be stored in the redo log buffer and online redolog files?
    can redo-log files not store this information?
    in fact, is it that when undo tablespaces exist in a database, the undo data/before image is stored in both the undo tablespace and also the redo log files?
    kindly clarify my doubt.
    thank you.

    This question has been asked many times before. The answer is always the same.
    Yes, redo contains the before image of data (and the after-image). Therefore, it **COULD** be used to roll back a transaction.
    BUT... Redo is written sequentially. Using it to rollback your transaction would involve reading through all the redo written by maybe thousands of other people. It would be painfully slow.
    Your transaction is, however, directly linked to just the UNDO that it generates (which is JUST the before image of the data). So, your undo is your undo and doesn't share space with anyone else's undo. Therefore, using it to roll back YOUR transaction is fast.
    The fact that undo is only the before image of the data also makes it faster than wading through a sea of before and AFTER images as you'd find in redo. About twice as fast, in fact, since there's half the data. Roughly.
    Redo also gets written and flushed to disk whenever there's a commit, 3 seconds are up or too much (1MB, actually) redo gets generated between flushes caused by other factors. Your redo gets flushed when those things happen, even if you haven't actually committed your transaction. And redo logs recycle themselves, meaning that your redo -even if your transaction hasn't been committed yet- can be over-written by later transactions. Try rolling back when that's happened, if redo was the source of your rollback data!
    Undo, however, cannot be over-written if the transaction has not been committed. Ever. If you don't commit for three years, there will be three years' undo stored in your database (assuming you had the space, of course!).
    I could go on, but that will do. Redo is there fore RECOVERY, after catastrophe. Undo is there for read-consistency (and the occasional change of mind). Two different functions. Two different mechanisms. Each one highly tuned to doing what it does, why it does it, most efficiently and effectively.

  • I am having troubles, when I open LR I get a message that there is an error and it will try to fix the error next time it opens, but I get the error next time it opens, and this is going on and on where I can not use LR, any suggestions?

    I am having troubles, when I open LR I get a message that there is an error and it will try to fix the error next time it opens. LR closes on it's own, I reopen it and get that same message next time it opens, and this is going on and on where I can not use LR, any suggestions? If I click on a different set of photos in the libary before I get that message I might or might not get the message next time it oipens, but I still can not get to those photos, and it is not just one or two but most of my photos. HELP!!!!
    Thanks

    The first thing I would suggest is for you to go to the folder containing your catalog, using your system browser. There will be a folder that has the extension .lrdata. Delete that folder, and then try to start Lightroom. If that doesn't work, replace your catalog with your most recent backup.

    It isn't a file, it's a folder. It will have the same name as your catalog, but will have the extension data. It will be in the same folder along with your catalog. If you need to use the search feature to search for *.lrdata.

  • Lightroom encountered an error when reading from its preview cache and needs to quit.   Lightroom will attempt to fix this problem next time it launches. " But it doesn't fix it!

    I get the following window on loading Lightroom 5.7 -
    Lightroom encountered an error when reading from its preview cache and needs to quit.
    Lightroom will attempt to fix this problem next time it launches.
    I have tried several restarts, without success. Also reinstalled Lightroom; no joy
    Any suggestions?

    Using your system browser (Windows Explorer or Finder), open the folder that contains your catalog. In Windows it is in your pictures folder and then in a Lightroom folder. Inside of the Lightroom folder you will find another folder that has the extension .lrdata. It will have the same name as your catalog except for the extension. You need to delete that folder, and then start Lightroom again. Lightroom will generate a new previews folder, and you should be back in business.

  • Can I still download Adobe 9 Pro Extended and will it work with Windows 8 64 bit?

    Can I still download Adobe 9 Pro Extended and will it work with Windows 8 64 bit?

    It is not clear what application you mean when you say Adobe 9 Pro Extended, so it ois not certain if it is available for you to download.  If you can diownload it, it will only be valid for a 30 day trial unless you already own it and have a serial number to activate the trial with.
    You can search the following site and see if you can find the trial version to download... this site is the only likely place you might find the software available for download.
    If you find it there, be sure to follow the steps outlined in the Note: Very Important Instructions section on the download pages at this site or else the download will not work properly.

    You cannot use a SIM card on a carrier locaked phone, other than a sim from the carrier the phone is locked to. You must first get the carrier it is locked to, to unlock your phone. Apple does not unlock phones.

    Go to the folder with you Lightroom Catalog (usually in Pictures) and delete the folder ending in .lrpreviews
    This contains the previews for the files Lightroom has linked to. They will need to be rebuilt which can be done while working or selecting an amount you want to rebuild and accessing the rebuild command in the Library Dropdown menu...

    Assuming the phone isn't jailbroken, the basic steps (as needed) are:
    Restart phone (you already did this)
    Reset phone
    Restore phone in iTunes using a backup
    Restore in iTunes as new, without using a backup
    See appendix B of the User Guide for details
    http://manuals.info.apple.com/en_US/iPhone_iOS4_User_Guide.pdf
    If your phone is jailbroken, this is the most frequent cause of the problems you described.  Restoring could permanently brick the phone.
    Note that your iOS is old and the current version is 4.2.8.  It's odd that it wasn't updated when your activated your phone in iTunes, being that you got it last Friday.

    How can I quit (close) Photoshop and keep all windows so that the next time I open Photoshop all the files that I had open are there already in the same position as when I closed Photoshop?
    I've been a Fireworks user for over 10 years and just switched to Photoshop. I cannot find a setting that will enable all my file windows to reopen when I quit Photoshop. This is really a problem since I often work on several files at the same time.
    Please let me know if the feature exists or point me to where I can post a message for a new feature to be implemented. The feature is a must for any designer working on large projects.
    Thanks!

    There is no such functionality. You could perhaps create a script that stores that info in a custom text file and arranges them accordingly in the workspace, but that's as good as it gets...
