Can't change default block size in dbca

10.1.0.3
solaris
I am using the dbca to create a database. When I go to the sizing screen and try to change the default block size this option is always greyed out at 8k.
does anyone know why? this happens even when i pick a data warehouse template.

There is a reason Oracle uses 8K as the default database block size for their warehouse template. Changing the default block size to a larger size generally does not result in better performance when both databases are allocated the exact same SGA memory allocations.

  • Change default block size on tftp server

    Is there a way to change the default block size on the tftp server so that it defaults to 1024 instead of 512
    I am aware that the client can accomplish this by:
    tftp> tsize
    tftp> blkzise 1024
    but I don't want the client to have to enter these additional commands.

    Were you ever able to get an answer on this? I have the same question.

  • Can I change default text size in CS5

    Every new document seems to open with a default text size of 12 pt. (or 0.167 inches). I am a sign maker and my typical artboard size is often 120" x 120" or larger.
    Is there a way to change the default text size so that new documents open with a text size of, say, 1 inch (or 3 inches, etc)?
    Any help would be greatly appreciated.
    thanks,
    Duncan McLean

    Open the New Document Profile that you use the most (from HD>Users><yourname>>Library>Application Support>Adobe>Adobe Illustrator CS5>en_US>New Document Profiles) or the equivalent path in Windows. Then go to Window>Type>Character Styles and double click on the [Normal Character Style] at the top of the list and modify the settings there to your liking. Save the document and restart AI.

  • Default block size for UFS format in OSX?

    Hi,
    I formatted an external drive as "unix format" (UFS) using Disk Utility, which subsequently became unrecognizable by the firewire controller. Now in a Unix box, the superblock of this drive is coming up as corrupted or nonexistent. Does anyone know where I can find the default block size for UFS in os x? I need to specify a backup superblock. Thanks!

    If it is just scratch, run some benchmarks with it set to 128k and 256k and see how it feels with each. The default is too small, though some find it acceptable for small images. For larger files you want larger - and for PS scratch you definitely want 128 or 256k.

  • How can I change the page size of a scanned PDF document?

    How can I change the page size of a scanned PDF document?
    I scanned a 50-page document with an HP 5610xi All-In-One using the software that comes with it: HP Scan Pro. Though the physical document has standard 8.5" x 11" pages, the PDF resulting from scanning has page size set to 35.42 × 48.67 inches (according to Preview's "Tools > Inspector". I want to resize the pages to 8.5" x 11". Shouldn't Preview be able to do that with "Tools > Adjust Size..."? When I try, the menu option is grey so I can't select it.
    I'm using Preview Version 4.2.

    Thanks for the insight; that explains why it's the wrong size. I selected 300dpi scanning (which is the default, actually), but HP Scan Pro evidently created a PDF with 72dpi indicated. I want it fixed because I want to distribute the file to other people and have them able to print or display it without problems.
    I still don't know why Preview won't let me change it, but your question about whether I wanted to print it did lead me to find a workaround: "File > Print" and "Save as PDF..." saved it with the correct page size.

  • Where can I change the buffer size for LKM File to Oracle (EXTRENAL TABLE)?

    Hi all,
    I'd a problem on the buffer size the "LKM File to Oracle (EXTRENAL TABLE)" as follow:
    2801 : 72000 : java.sql.SQLException: ORA-12801: error signaled in parallel query server P000
    ORA-29913: error in executing ODCIEXTTABLEFETCH callout
    ORA-29400: data cartridge error
    KUP-04020: found record longer than buffer size supported, 524288, in D:\OraHome_1\oracledi\demo\file\PARTIAL_SHPT_FIXED_NHF.dat
    Do you know where can I change the buffer size?
    Remarks: The size of the file is ~2Mb.

    Hi,
    The behavior is explained in Bug 4304609 .
    You will encounter ORA-29400 & KUP-04020 errors if the RECORDSIZE clause in the access parameters for the ORACLE_LOADER access driver is larger than 10MB and you are loading records larger than 10MB. Which means their is a another limitation on read size of a record which is termed as granule size. If the default granule size is less then RECORDSIZE it limits the size of the read buffer to granule size.
    Use the pxxtgranule_size parameter to change the size of the granule to a number larger than the size specified for the read buffer.You can use below query to determine the current size of the granule.
    SELECT KSPFTCTXPN PARAMETER_NUMBER,
    KSPPINM PARAMETER_NAME,
    KSPPITY PARAMETER_TYPE,
    KSPFTCTXVL PARAMETER_VALUE,
    KSPFTCTXDF IS_DEFAULT,
    KSPPIFLG MODIFICATION_FLAG,
    KSPFTCTXVF VALUE_FLAG
    FROM X$KSPPI X, X$KSPPCV2 Y
    WHERE (X.INDX+1) = KSPFTCTXPN AND
    KSPPINM LIKE '%_px_xtgranule_size%';
    There is no 'ideal' or recommended value for pxxtgranule_size parameter, it is safe to increase it to work around this particular problem. You can set this parameter using ALTER SESSION/SYSTEM command.
    SQL> alter system set "_px_xtgranule_size"=10000;
    Thanks,

  • How can I change the page size of a pdf so i can view it on my iphone more clearly?

    How can I change the page size of a pdf so i can view it on my iphone more clearly?

    I think there may be more to this question than you say.
    If your PDF page is say, 8 x 12 inches, and you found a way to scale it to 25%, changing it to 2 x 3 inch, shrinking everything on the page to quarter size - wouldn't it look exactly the same on the iPhone? It's just going to be the same as zooming.
    Or were you hoping for something more like in Word, where changing the page size keeps everything the same size and spreads it over more pages? That isn't something you can do.

  • How can you change the font size in the application and system headers?

    How can you change the font size in the application and system headers?  I searched the system and finder prefs to no avail.  Changing the screen density is not a good option.
    Thanks

    I downloaded Tinkertool.  Found the font section and increased the size of most selections.  The only thing that changed that I can see is the window label.  The apple line, bookmarks line, the tool bar in safari are all the same---font size of about 4.  Found the finder "show view options" but that didn't seem to change anything either.  I'll keep working.  Restarted all apps after changes as well.

    Vandushia,
    The Workspace size is fixed, 16,384 points.
    I am afraid you will have to work in a suitable scale, which could be 1:2, 1:4, 1:10, or whatever is most convenient.
