Several files of data with autoextend ON & OFF

Hello

Is there any negative impact, and if I add a new data file to the storage space with auto-prolonger ON, while the old data file for the same storage space is OFF.

Here is my scenario:
I have 3 groups of disks in my ASM (DATA1, DATA2, and DATA3) instance.

Now, all my tablespace's datafiles of Data1 with auto - THEY extend. (It was a mitake creating tablespace). To distribute the disk space, I intend to add a new data files of DATA 2 & 3 for half of the storage space.
And for these storage spaces, I'll turn off the auto-prolonger for old data files and marketing the autoextend for new data files.

The idea is, Oracle will begin to load the data for the new ASM disk groups in the future and I'll get the appropriate disk space distribution. Is there a problem with this approach? (In particular, when one of my datafile autoextend is DISABLED and other is lit).

Your advice is appreciated!

Kind regards

In fact, it is a valid strategy to ensure that some datafile (s) in some single user grow while others stay the same size.

Correctly, several data files must have been created earlier so that data would have been divided on all files. However, you can always add new data with AUTOEXTEND ON files and set the old files of data AUTOEXTEND off at any time (and switch ON and OFF as needed if you need to dynamically manage the use of the space of the file system, when you move data to new file systems files).

    For every person who says 'I can manage the integrity of data loading data', there is a person who cannot.

    I worked in large single database systems, we had 1.25PB (Yes petabytes) of the disk and I've never seen an improvement in the performance of the deactivation of the constraints that have made a difference worth having.

    On the other hand I was paid a lot of money to clean up the mess after the fact, when the promise of the integrity of the data by code failed to materialize.

  • Load several binary files (.r32/.r64) with DataLoadSel or similar functions

    I want to automatically load several R32-records in the database, there is no DAT file that contains the structure, it must be created. Currently my script gets a list of files one then a loop produces a header for each file and the bed. The structures are beeing set correctly, the first file is read correctly, but after the data of channel of each following file are empty/filled with zeros nearby.

    If I read about each file, the data is correct. There is a new DataFileLoadSel function, but it cannot read the binary data files.

    I think indexing is correct. I have no idea why playback does not work, any suggestions?

    Code:

    While (numLoop > 0)

    Call HDDelAll()

    GHDChnNo = DynChannelNo

    GHDChnLength = ChannelLength

    GHDChnType = "EXPLICIT."

    GHDChnFile = chnFile

    GHDSaveType = 'BLOCK '.

    GHDChnIdx = 1

    GHDChnMode = "REAL32".

    Call HDCreate()

  • I need to know the file current date/time number stamp and the version of "spoolsv.exe" in Vista Home Premium 32-bit with SP2.

    I need to know the file current date/time number stamp and the version of "spoolsv.exe" in Vista Home Premium 32-bit with SP2. My spooler file got corrupted and I need to know what that the stamp of date/time on the latest version of the file: spoolsv.exe. I did a search on my hard drive and found 8 copies of the file with 7 different dates. I need to know which copy in my file C:\windows\system32\. I suspect that the problem was caused by some kind of malware. I think that some of the different versions on my machine of the initial installation of the Vista, SP1 and SP2. 3 copies that would explain. I tried all the suggestions in this forum and several others. I tried sfc/scannow and it simply replaces the corrupted file by another. I understand how works this file and a simple copy will do the trick if I knew that the file to use. I know that I don't want to go back to the first version of 2006.  BTW... my symptoms are all my printers have disappeared, and when I try to 'add a new printer' I get an error message saying that my spooler service does not work. When I opened my services window it shows that indeed, he is arrested, but I will not start because the description column contains only the code garbled machine indicating that the file is corrupted, or it may contain a virus. I had been using F-Prot until this virus got by and now I use AVG. I scanned my machine with several cleaning packages and it is is more infected, but I worry that from this corrupt file grow something. I know that the problem is not with my printers or drivers, because everyone on my home network can print on all of my printers. None of the people I know are on Vista 32 bit. They are all running System 7 or XP. I have XP, except that a few years ago I suffered from the "Syndrome of Pepsi" on my laptop and when I bought a new HP, it came with Vista.

  • Activity FTP - mget several files with dynamic names

    Hi all

    Hope everything goes well.

    I was wondering if there was a way to configure the FTP activity to transfer several files with dynamic names to location of the source on a daily basis.

    For example, my source files are set with date values (source_filename_ < MMDDYYYY > _ < hh > .txt):
    source_filename_12252009_00.txt
    source_filename_12252009_06.txt
    source_filename_12252009_12.txt
    source_filename_12252009_18.txt

    I would like my process flow to do would be to download just the 4 day files based on a script ftp dynamic as follows:

    Open ${Remote.Host}
    ${Remote.User}
    ${Remote.Password}
    CD ${Remote.RootPath}
    invites to the wide
    mget?
    quit smoking

    In the script of DOS commands, you would have with a wildcard as mget command:
    mget source_filename_%DATE:~0,2%%DATE:~2,2%%DATE:~4,4%*.txt

    How should be done on the implementation of this in OWB? It requires a user-defined substitution varilable any?

    FYI, I use version 10 gr 2.


    See you soon.

    Hello

    If you are able to achieve your goal of a script of DOS commands, then you can call this script for a user defined, OWB process flow activity.
    I hope this helps.

  • Reading several files / locate the data source during execution

    Hi all

    I have a requirement of the company in which I need to read files to different folders. This system is not hosting the ODI agent. There are two folders, the folder A and folder b. Two records may have any number of files. My intention is to read the files in a folder and write the data to a table in a database that resides in another system. This forms a flow for me. For the B folder, I have a similar flow. All files (in the folder A and folder B) have the same structure. The requirement is to read A book during the week and the B folder on the weekend. The system that has the database also runs the ODI agent.

    Here are my questions:

    1. How can I read several files one by one in a folder? Because the read files must be archived, they need to be written in a different folder, file C (for example). How do you archive part? Please note that this machine does not run ODI agent (network share could be an option, but we try to avoid it.

    2. can I have only an interface to read files in folder A and folder B? Everything else remains the same (the processing logic/transformations etc.). Indeed, is there a way to dynamically switch between two files (using a variable, perhaps).

    I've not worked with files and so any help is greatly appreciated.

    Hi Sankash,

    Hopefully I can help you achieve this task.

    Re: import files in a table

    1. you can update the status of the process of the files in a journal/temp table.
    Based on the State of the (transformed) file in the table, you can check the files that has completed its process correctly.

    machine does not run ODI agent:-J' have it is implemented the same type of scenario, in which I am downlading all the files in a common location and treat it from there.

    2. one of the solutions is that: -.

    create two interface with the same structure, but the source table must point to the folder A and B
    Create a variable (week/check) and based on the value, you can call the interfaces.

    second option: -.

    If you're downlaoding the files in a common location, you can reach the spot through a single interface (down load files from folder A or B according to in week/weelend)

    3. If all the files have the same structure, you need only a data store and it should be a variable data store.

    If something is not not clear please me ping / mail to my id (good that now I don't get enough time to go through the forum discussions)

    Also if you need I can send you a diagram wokflow for this loop (read multiple files one by one in a folder)

    now, I want to play a sound specified (like a song in my desired folder 3s) signal which cross above the specified value range. then after the desired time, it will wait still new cross above the specified value and this repetition of the procedure until I stop the program.

    I use this for reading data and part VI mentioned which belongs to her is empty and I don't know what I have to do?

    altougth I use an another while loop for his apartment because I want to save time CPU.

    Thank you.

    I recommend you do the data type of the notifier a cluster that contains a path and a numeric (double).  The path indicates the reader what file to play.  Digital is the duration.

    Now in a way a bit complicated, but really good stop your second loop.  Do not use a second notification.  Instead, send the normal notification but not use a path for the path in the cluster.  Your second loop can write a check for the path of a not and stops when that is received.

    How to change the extensions on several files with Windows 7?

    You hear no doubt, is that your movie software will only recognize certain types of image file formats.  If this is the case, you will need to reformat format files to any format PNG is recognizable by the software.

    Rather than we guess, please identify your «film» software

    Download and install IrfanView, which is a free utility for images.  http://www.IrfanView.com/

    IrfanView has the ability to read a great many formats of image files.  It can also convert image files formats.  And even better - for you - it can do all these things on a batch of files.

    As test, after I installed IrfanView, open one of your PNG files.  Now click on file > save as, and select the 'Save as Type' to be little matter the file type of your movie software will accept.  Save the file.  Make sure your movie software can accept the new file.

    Once you are convinced that you can modify files that you have in a format that you can use, use IrfanView

    File > Batch Conversion/Rename command.  If necessary, see IrfanView help on this topic.

    Thank you for your attention,

    Thank tzander reminding me the idea. Method of cascades is not good for me because all of the kernel code is written by Native. If I change the channel to QString, I need to change a lot of codes.

    Solution is below.

    While (access (rawfilename, F_OK)! = - 1) {}
    rawfilenamecount ++;
    sprintf (format, RawFileName, rawfilenamecount);
    fprintf (stderr, "file exists");
