DB restoration and recovery when you use followed the change block

Does anyone know of a document that explains the restoration of the database and recovery when you use the block and the incremental backups the track changes? I understand how to turn the OTC market, and how it can shorten the time to do an incremental backup. I need advice when choosing the frequency of backups of 1-0 and level level and how it affects my food options. I also need to decide if the level 1 backups update the copy of most recent data on the disk file.

If the copy of the data on disk file is updated by each level 01:00 am I right to say that I can restore to point in time that this moment occurs after level 1 has been taken? If so, then maybe I don't have level 1 update the copy of the data file on disk. If I take a level 0 Sunday and daily level 1 Monday - Saturday, so I think I can restore to any point in time after the 0 level.

A lot of documentation explains my backup options, but there is less material tell how my backup choice affects my food options.


Thank you
Bill

BCT applies to backups only, there is no connection with the restoration.
I think you are confused about the difference between

(1) incremental of backups
and
(2) "normal incremental backups".

In the first case (see http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmbckba.htm#CHDEHBFF), in the base implementation because an incremental backup is applied to a still image copies and you cannot go back to an earlier point in time – before the changes applied.

'Normal' incremental backups are done after a full backup (level 0), you can return to the level 0 backup earlier.
RMAN follows rules of detention, in the basic version of an incremental backup that is updated, you have a retention of redundancy policy 1. This means that a full backup (image of copies, which are updated by the incremental backups again and again) is available.
Backup incremental 'Normal' in most cases after a few days recovery windows - a time window.

  • Questions about privacy and security when you use Safari for Windows

    I have Itunes + Quick Time Player installed to download music and some time ago I had the opportunity to download Safari for Windows.  I used it a few times, just out of curiosity, and I noticed that it is much faster than IE7, so I plan to use it regularly, but before that, I have a few questions:

    -someone at - it tested (or uses) Safari for Windows, and what are your results?

    -What is save to use as Firefox or Opera, both recommended as alternative by our experts at the HijackThis forum?

    -the programs that I installed (Online Armor firewall, AVG 8.0 suite, MBAM with protection in real time enabled RogueRemover Pro with immune protection enabled, WinPatrol, SpywareBlaster) offer the same protection when you use Safari for browsing?

  • Swatches to Pantone which disappears when you use only the percentages of the swatch

    Hi I came across something that might be a bug in Illustrator CS6...

    Here's the thing... I did a drawing or model in the CS6 (colorspace) and have used several Pantone swatches.

    Some Pantone colors, I used only a percentage of the color, for example, the design consists of: 75% of Pantone 485 C, 32% of Pantone 1345 C and 100% Pantone 154 C.

    In the design process, I used several other colors Pantone, which are not used in the final design, but they are still in the tab/list of Swatch.

    For example, when you click on the triangle (top-right) > "Select" is not used all the.., Pantone colors which are used only as percentages (Pantone 485 C & Pantone 1345 C in the example) are chosen as "Unused" ?

    I've been using Ai CS4 prior to this version, and in this version, it wasn't a problem.

    I could you the percentages of Pantone colors without the shade chosen as 'Unused'.

    I don't really want to manual remove every unused nuance by dragging it in the trash.

    It would be such a time waste handling.

    It's really annoying that I work for a printing and design company, and the need to save the Pantone colors that are used in the design, even if they are only a percentage of the Pantone color chart.

    Could someone please explain me why or what the reason is that this is happening...

    I missed something?

    Thank you!

    When you created the hue of the color Pantone you did that made a shade? Or did you just leave it as it was?

    If you don't have whereas they should stay, but if you just changed the tint but did not save it as a sample then the pms color is no longer used because it is a specific hue. At least that's how it seems to work.

    I agree with you that you always use the PMS color and have to stay without the need for nuance, even if it a shade of each color is a good idea.

    I would say it is a bug and should be reported as such. Cn do you here:

  • (ORA-00955) conflict of naming for index and constraint when you use a unique index (.. desc,.. CSA)

    Hello

    indexes and constraints are in different namespaces, so it should be possible to give them the same name.

    In the following case that apparently does not work:

    create unique index orders_year_show_uq
      on orders (year desc, show_orders asc);
     
     alter table orders
      add constraint orders_year_show_uq unique (year, show_order);
    

    When I run these statement, I get a "SQL Error: ORA-00955: name is already used by an existing object". ""

    If I clean and I execute the same instructions as above with the only difference on the 2 line, using "asc year" instead of "year desc":

    
      on orders (year asc, show_orders asc);
    

    then it success.

    I can't explain it, you have an idea?

    Thanks in advance.

    Kind regards

    Giovanni

    First of all, you have show_orders in index and show_order in the constraint. I'll assume that it's a typo. Second, when you create constraint without index enhance the specification Oracle seeks indexes existing on the same set of columns in ascending order. If this index does not exist (and it's your case, since one of your columns to index is in descending order), Oracle tries to create one with the same name as the constraint. That's why you get ORA-00955: name is already used by an existing object. In general, you can specify explicitly the index name to force the Oracle by using the existing index. But it will not help you. If you issue

    ALTER table orders add unique constraint (year, show_orders) orders_year_show_uq using index orders_year_show_uq;

    You will get the ORA-14196: specified index cannot be used to apply the constraint.

    In any case, Oracle does not support using index DESC for PK/UK.

  • Photoshop Elements 5 freezes and restarts when you use Vista

    I have a little problem with Photoshop Elements 5. When I first start the program and click on 'File' system crashes. If I wait about 30 or 40 seconds, it retrieves all and then when to work them again together is very good. It's really very annoying when you start the program, and if someone else has had this problem and knows a difficulty, I would be very grateful.

  • How to escape the quotes and commas when you use the command of the coil

    I am creating a file .cvs with data in my database. I call the function of coil and below select stmt

    ' Select ' ' ' | ID | '","' || name | '","' || Description | '","'

    I want everything to be separated by quotes and commas. Description data can have quotes and commas so how I get away from them in my queue code so that when I use SQL Loader data will get entries in the database correctly.

    Thank you!

    Hello

    If the field is closed, so there is nothing else you need to do for the column separator (en).

    To use the character encompassing ("") in the field, double it, the same way you use two single quotation marks to signify a single_quote into a SQL string literal:
    {code}
    ' SELECT ' ' ' | ID
    ||     '","'     || name
    ||     '","'     || REPLACE (description
    , '"'
    , '""'
    )
    ||     '"'

  • Move the files, folders, and applications when you use several desktop computers

    I have configured my MacBook Pro to display several different offices, based on several types of work that I do. I'm having two problems: (1) get the apps in the dock to show only in the dock on specific and (2) workstations, get the files and folders to broadcast only on one specific office.

    Re: (1), I followed the instructions from Apple I found online, but all applications in the dock show in the dock on each other in all cases.

    Re: (2), I don't see a menu or option to specify desktop computers. They're showing on all my workstations, which isn't what I want.

    Thank you in advance for your help!

    The Dock is the same, no matter what you are in office. It cannot be configured to display only the items to come on a computer desktop and other articles on others. It is similarly of the icons. An icon that you put on a desktop will appear in all work positions.

    Now you pouvez specify certain applications appear in specific jobs and this applies to the Finder as well so you can have icons of documents and folders appear on a single desktop computer. Other workstations will all show no icons. If you choose this option, you can then open a window to a folder on the desktop that has the Finder, and then move it to another office.

    Before Apple, desktops implemented, there are several utilities which enabled us to operate more as you want, but unfortunately, they are now gone.

  • Error-2147352567 when you use save the vi report

    Hello

    I am developing a software test bench end line for a company. Everything was going well until I met an unexpected error which I don't understand. My code works a simulation engine and stores data in two excel files. When I have the path disconnected to save the report to the File.vi (screenshot 1), my program works without problem and records one of the files and returns an error due to the vi save report being disconnected (as expected). But when I connect the path to save the report to the File.vi, I get an error-2147352567 (screenshot 2) at a table to append to report.vi elsewhere in the code, which worked perfectly well until the road was connected to the vi to save the report. Also, now the second excel file is saved because its path has been connected. I don't understand what is the question. I couldn't find any source that has given me a reasonable solution to the problem either. I use Labview for less than 2 weeks, so forgive me if I forgot something.

    Hi DPAC.

    My apologies for the confusion in the previous post, I thank very you much to clarify it.

    Following my last post; the error was due to a race condition. There is no data flow between two separate writing report files. This means that LabVIEW will try to run the two bits of code in parallel. However, it was sometimes causing one of the sub-vis to be called by two different parts of the code at the same time, causing the error.

    This is the reason for which the code executes without error above if you have disconnected the path to the first 'save report to File.vi', because this part of the code was not running, allowing the second party to run freely.

    To counter this I simply wired terminal 'error' "save report to File.vi" (the one that used the All_Saved.xlsx) in the terminal ' error in ' of the 'new Report.vi' (one who has used the Template.xlsx). Because the screws will not work until all entries are filled, this forces the writing of the first report before the writing of the second report, not occur at the same time.

    I have attached the revised version of the "EOL_V1.vi" where you will be able to see how I wired errors to force execution.

    I also noticed that you have not initialized your shift register "speed". This means that every time that you run the program, it will retain the last value from the previous execution. Is - this intentional? This means that your worksheet does not properly update if you run the program twice in a row.
