Data file can be resized

Hello world
I read a book
Oracle DBA Interview QuestionsYou will most probably be asked (by dynamics, U.S. publishers. published 2011).
And I think one question is strange (or incorrectly).
It's

21: explain the properties of the data files?
Answer:
Each data file can be associated with that a single data base and once it is created it cannot change its size.

I'm also studying 11g OCA review at the present time, and I know that we can change the database data file to resize the data file.
Why is the anwser as that?
It is a mistake to the book? Or I get the wrong question. (English is not my native language)
Or this applies to an older version of Oracle.

I'm quite confused.
Thank you.

You can certainly change the size of a data file - it increase any time and reduce or decrease it in special circumstances. This has been true for as long as I've worked with Oracle (from v7). It is best to read the documentation official and formal training of preparation material for the certification exams.

  • firefox desktop data file, can I remove it?

    Folder of old data of firefox on desktop... what should I back up this or can I delete it? My computer crashed at point, & may have created, then... do not remember why it is there. I want to just make sure it's ok to delete

    Sounds that you have made an update of Firefox and have created a new profile.

    When you refresh/Reset Firefox then created a new profile and some personal data (bookmarks, history, cookies, passwords, data form) are automatically imported.
    The current profile folder will be moved to "Old data Firefox" folder on the desktop.
    Installed extensions and other customizations (toolbars, Pref.) that you have made are lost and must be redone.

    It is possible to retrieve data from the "Old data Firefox" folder on the desktop, but be careful not to copy the files corrupted to avoid transporting more problems.

    If the new profile works and you have confirmed that you have all the data you need then you can delete this folder.

    You can copy files like these in your current Firefox profile folder.

    • bookmarks/history: backups in the bookmarkbackups folder and perhaps places.sqlite, if you really need the history
    • other SQLite files cookies.sqlite (cookies) and formhistory.sqlite (saved form data)
    • logins. JSON and signons3.txt (decryption key) of the saved passwords in password manager
    • Permissions.SQLite and, possibly, content - prefs.sqlite permissions and Site preferences
    • cert8. DB for stored intermediate certificates (Certificate Manager)
    • sessionstore.js to open and pinned tabs and tab groups
    • Persdict.dat for the words that you added to the spelling dictionary

    You can retrieve more personal data.

    You can use this button to go to the current Firefox profile folder:

  • Photoshop will not open/create new files, can't resize images etc.

    Hi all.

    So I'll start with the basics; I use Photoshop 7 (and Yes, I use it for a reason, I'm not interested in the migration to this jumble of creative cloud new $1000), we Australians get us torn a new and I am happy with the $50 I paid for my copy years ago. (Please don't tell me the solution to my problem is simply to level and go bankrupt. Yet once again, I am using 7 for very long without problem).

    I use the 7 for almost a decade without problem. I stick with it because so far, he has done everything that I need, has been reliable up to this point, and my plugins work correctly with the newer versions. I also use a system more older-spec (Windows XP, 3 GB of ram etc.) I do a lot of work with former game engines, Source engine etc.

    The question that I have doesn't seem to be Photoshop-7 States, however, there are many threads on this point that remained and arrive in CS3 etc. and modern copies as well. I uninstalled and reinstalled nothing doesn't. Basically, I can't open the reliable files with it.

    If I click with the right button on any image file in Solution Explorer and click 'Open with-> Photoshop', photoshop will launch, however it does not open the file. I double checked to make sure that the file wasn't just opening offscreen, however it is certainly not opening at all (like the "close" option does not become available).

    If I launch photoshop manually, click on file-> open-> it will open this file, BUT it will not more files open after that.

    She also is very very picky with simple controls, such as if I hit CTRL + T to go in processing mode and then try to resize an image, I have to click and drag the corners at least 5 - 6 times before it will recognize that I do, and it will also ignore the resizing I perform and break back to normal. Sometimes, I have to click more than once things to get them to sign up. This does not occur with any other software etc, so I excluded that there is a problem with my mouse.

    This happens only one day, and I can't think of any particular system changes it will likely cause (IE no abnormal plugins installed recently, no major changes in hardware or software). Unless my keyboard has a stuck key or something strange, I am absolutely at a loss

    Is there someone who can help me or has heard of this problem?

    I'm a fool.

    I suppose the work disk was full or something else. A simple reboot seems to have solved the problem. (I often my system running up to 64 48 hours at a time without that it recharges) as my working days are about 36 hours straight, so it could just be a constraint of XP.

    I hope that this solves the problem for someone else who she sees. Restart your pc from time to time, give him a table open memory to work with.

  • RESIZE data file

    Hi all

    I have a tablespace called "syscom" and there a data file size is 4 GB.
    Now I increase 1 GB to this data file, so that the total tablespace size is 5 GB.

    When I run below coment: -.

    ALTER database datafile ' / oracle/ora10g/ecms/syscom01.dbf' size to 1 GB.

    reduce the size of 1 GB tablespace and total size is 3 GB, now.

    What is the query, to increase the size of the data file, then.

    Rgds,
    Pravin

    create a tablespace again with 5 M

    SQL> create tablespace new_data datafile 'C:\miBBDD\oradata\FRAN\newdata_01.dbf' size 5M;
    
    Tablespace creado.
    
    SQL> select name, bytes/1024/1024 from v$datafile where name like '%NEWDATA%';
    
    NAME
    -------------------------------------------------------------------------------
    
    BYTES/1024/1024
    ---------------
    C:\MIBBDD\ORADATA\FRAN\NEWDATA_01.DBF
                  5
    

    now resize to 3 m

    SQL> ALTER DATABASE DATAFILE 'C:\MIBBDD\ORADATA\FRAN\NEWDATA_01.
    DBF' RESIZE 3M;
    
    Base de datos modificada.
    
    SQL> select name, bytes/1024/1024 from v$datafile where name like '%NEWDATA%';
    
    NAME
    --------------------------------------------------------------------------------
    
    BYTES/1024/1024
    ---------------
    C:\MIBBDD\ORADATA\FRAN\NEWDATA_01.DBF
                  3
    

    The new tablespace size is 3 m, because I resize at 3 m, if you resize a low size will shrink the data file, if you resize a high value datafile will increase.

    alter database datafile '/oracle/ora10g/ecms/syscom01.dbf' resize to 1GB. 
    
    tablespace size reduce by 1GB and total size is 3GB, now.
    

    Are you sure?
    Please post the output of:
    SELECT name, bytes/1024/1024 of v$ datafile, whose name like '% SYSCOM % ';

  • Incomplete data file recovery

    Hello

    I use oracle database 10g (10.2.0.10) in RHEL5. I want to make a point in time recovery a backup data file. Through RMAN, I published the following command

    RMAN > run {}
    2 > sql ' alter session set nls_date_format = "dd-mon-yyyy hh24:mi:ss";
    3 > set until that time August 21, 2011 13:04 ';
    4 > restore datafile 4;
    5 > recover datafile 4;
    6 > alter database open resetlogs ;}

    But RMAN made a full recovery. Yet once again, I deleted the data file and restore the backup data file. Now, I wrote the following at the SQL prompt

    SQL > alter session set nls_date_format = 'dd-mon-yyyy hh24:mi:ss ";
    Modified session.
    SQL > recover datafile ' / u01/app/oracle/oradata/ORATESTDB/datafile/o1_mf_users_751h7fmh_.dbf' until August 21, 2011 13:04 ';
    ORA-00274: illegal until recovery option

    It displays the above error. But I am able to perform incomplete recovery of the complete database using RMAN same as above.

    Done datafile point-in-time recovery is not possible? or is there something wrong in my approach?

    Kind regards

    007

    A data file can be recovered to a point in time which is incosistent with the rest of the database.
    (why? Data integrity! A table with several extensions that can cover several data files. You can't have some scopes with data from 12:05 and other extensions into another file of data retrieved using data from 10:05! Even if it's a single datafile tablespace, you will violate referential integrity (whether or not they are applied) If, say, the SALES table has entries until 12:05, but the SALES_LINES table has entries until 10:05!)

    You can make a Tablespace recovery time by using an auxiliary Instance and then copy the tablespace back. You must maintain integrity.

  • variable length data file

    Hello
    I need assistance with the values in my data file. I search and can not find info on it. I'm sure it's there. However, I spent 3 and a half hours to research.
    someone can help me.
    I have three files.
    created the sql table file that contains a single table.
    a control file
    a data file

    the table contains the columns date and created_by column.
    I have these columns in my control file with the given position.
    My question is:
    In the data file.
    can the date columns, I use the sysdate to a value?
    If so, it means a date achual when it's loaded?
    Second:
    in my data file.
    can I use the USER name as a value?
    I want to
    the user, like me, when I load the data file and then ask her to varify that this is going to work, I'll see my username in the created_by column.

    Thanks for your help
    kabrajo

    If I understand correctly, you want to load the current date/time and the current user for each line.

    Here's a recent thread similar to what you need - documentation links are here
    user input windows OS when loading data using sql loader

    In this case, the poster was interested in an OS/user. Your question is more simple. You can use these lines in your file of control for the user name and datestamp colums

    ...
    datestamp EXPRESSION sysdate,
    username EXPRESSION user,

    No, you do not want to delete the file.
