• value are of a sequnec and looking at a very large number

  Hello
  
  We have a table that has a column filled with a sequence - it is maintained by code in owb, but is growing at a rate higher than expected
  
  for example sequence begins to tell 10000000000, expect the next row until the b created with 10000000001 but the big gap between the two.
  
  Have a separate ticket raised with oracel for this as maintained by dimesnion opertaor code.
  
  However, I have two or three sequences of questions reagrding.
  
  (1) can how big be
  
  (2) if we try to application numbers that over 14 digits begins to show the e in the tool that we use (pl/sql developer) is there a way to make sure that we see the integer (sqlplus?) and
  I'm assuming that say if had number column that very large say 18 digits long attached to an another numbers table 18 long then no problem?
  
  Thank you

  If you take a look at the documentation for creating a sequence, you will see that the maximum value is 10 ^ 27, assuming that you do not specify a maximum. If you have generated 10.000.000.000 (10 ^ 10) sequence values every second, you don't miss in 10 ^ 17 seconds which is about 3 * 10 ^ 9 years (3,168,808,781 or 3 billion years). The Earth is approximately 4.5 billion years if your sequence would not run out of values for about half the current age of the Earth. For most systems, it's a lot.

  In SQL * Plus, you can control the display of a column using the COLUMN command

  SQL> ed
  Wrote file afiedt.buf
  
    1* select 1e20 col from dual
    2  /
  
         COL
  ----------
  1.0000E+20
  
  SQL> column col format 999999999999999999999999999;
  SQL> select 1e20 col from dual
    2  /

• Since graduating from version 22 (updated channel version), I had a few days with a very large text; Today, Firefox will not start. How to run again?

  I searched a file in Firefox program .exe files, but it doesn't seem to be any where. I would like to uninstall, download a new program and reinstall, but I will not lose rather bookmarks and other settings.
  Running Windows 7 on a Sony Vaio laptop. Any suggestions? Thanks in advance.

  Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox, you WILL NOT lose any bookmarks, history and settings. Please follow these steps:

  Note: You can print these steps or consult them in another browser.

  1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
  2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
  3. Remove the Firefox installation folder, which is located in one of these locations, by default:
     • Windows:
       • C:\Program Files\Mozilla Firefox
       • C:\Program Files (x 86) \Mozilla Firefox
     • Mac: Delete Firefox in the Applications folder.
     • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
     1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
     2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

  Please report back to see if this helped you!

• Why is my defrag program reported a very large number of files not movable?

  most of these files appear to be located in c:\system volume information and 25 system files.

  I suspect especially two files \windows backup and \windowsimagebackup. Cannot access this last all as my administrator privileges do not appear to be good enough. Remove the statement are not so much denied as totally ignored. backup Windows does not recognize filed.

  a screen CAP is lower with arrows indicating the files not movable.

  Obviously, the free space on the drive is defragmented seriously, but not movable files prevent further action.

  anyone can shed light on this apparent conundrum?

  This problem has been resolved by deleting all restore points.

• hash with very large internal table plan causes ORA-01652

  Hello
  
  We have a select with dubious plan:
  
  SELECT * FROM T1 where T1. F1 in (select T2. F1 T2)
  
  Plan:
  | ID | Operation | Name | Lines | Bytes | TempSpc | Cost |
  | 0 | SELECT STATEMENT | 59 M | 12G | 1 401 K |
  | 1. SEMI HASH JOIN | 59 M | 12G | 55G | 1 401 K |
  | 2. TABLE ACCESS FULL | T1 | 260 M | 52G | 489K |
  | 3. TABLE ACCESS FULL | T2 | 209K | 1843K | 84.
  
  As you see a record 260 million (52 GB) T1 and T2 has approximately 200,000 records (approximately 2 MB)
  Oracle chooses the hash with T1 inner table join. Thus all T1 is tempted to read first in memory.
  And when the memory is full, the TEMP tablespace is filled.
  And because the TEMP tablespace is less than 55 GB, an error has occurred:
  ORA-01652: unable to extend segment temp of 128 in tablespace TEMP
  
  Question:
  Why oracle choose the hash with inner table so big join?
  And how can we solve this problem?
  
  Other notes:
  T1 and T2 is analyzed today.
  Presumably no index or table.
  The database is Oracle 9i Enterprise.

• CC of Dreamweaver on iMac very slow to open sites with a large number of files

  In recent weeks, a site I've worked regularly for several years began to take 10-15 minutes to open. A pop up says it checks the files, but the button that should allow you to escape this process does not work. The site has about 120 000 files located in different folders, and this was never a problem in the past. To access the site, the only way is to wait until the course ends and the spinning ball to go. I read the thread on the port of Skype settings, but I think that this may be a different problem because even though I have installed Skype I rarely running and only one of my sites is affected.

  Any ideas?

  With a large number of files, it would be a good idea to disable the cache of Dreamweaver for this site.

  1. Site > Manage Sites.
  2. Select the site, then click on the pencil icon to change site settings.
  3. Select Advanced settings > local news in the list on the left of the Site Setup dialog box.
  4. Uncheck the Enable Cache.
  5. Save > fact.

  Another possibility is that your Dreamweaver cache is corrupted (probably with as many files). See remove a corrupt cache file.

• Large number of files in the directory profile with at sign in name

  Hello
  I noticed that my wife s v35 Firefox running Windows 8.1 32-bit has a large number of files such as:

  cert8@2014-03-25T19;02;18.DB
  Content-prefs@2014-01-30T21;28;58.SQLite
  Cookies@2014-01-08T18;12;29.SQLite
  HealthReport@2015-01-20T06;44;46.sqlite
  Permissions@2015-01-19T10;26;30.SQLite
  webappsstore@2015-01-20T06;44;48.SQLite

  Some files are entirely new.
  The original files get backed up somehow, but I can't figure out how. My PC does not contain such files.

  Thank you

  I'm sorry, this has nothing to do with Firefox. I was watching the backup directory created by Memeo autobackup. The original profile directory is OK.
  Sorry once again.

  Hello world.

  I have a situaton that I can not open a previous file created with a large number of files stored in it.

  There at least 2000 photographs, and when I try to browse, the content is never displayed.

  Curiously, traversing a small file with say, 1000 records, it opens right.

  I have reset the permissions without effect and I can't open it with RAIDar is.

  Any suggestons? I'm about to happen for the pallets of the defibrillatior!

  Thank you!

  Hello Stephen

  I was finally able to recover my files 3000 + using 'snapshot' and download the files on my computer!

  I found a date where they were all visible.

  I bought a new RN204 and move them to the new unit, as well as all my other data.

  It is much faster with more memory as well.

  Thank you

• CRUD for tables with large number of columns

  Hello

  I work for a government agency in Colombia, and we do a poll with about 1200 variables. Our database model has few paintings, but they have a large number of columns. Our Oracle 11 g database is, and we do not use Oracle APEX. I've read about APEX and it seems to be useful to generate quick forms and reports. However, I would like to know if it is possible to generate CRUD for tables with many columns, and that would be the best way to do it.

  Thanks in advance.

  Carlos.

  With the help of 250 point on a single page is actually really bad for the user experience. I would probably be it cut into pieces and using several pages to guide the customer through it as a workflow.

  You could also add some pop-up windows which includes some elements of your table, just saved on other pages. But I probably don't like that.

• Georaster: Import very large images with sdo_geor.importFrom

  Hello

  What is the best way to import images of very large (> 50 GB) (GeoTIFF, TIFF, etc.) in a table georaster. Actually I don't have the image in a single file, but in raster 1 GB files.

  Approach 1:

  Import each image 1 GB with sdo_geor.importFrom block into small tiles (block settings) within the oracle and merge 50 rasters then into a large raster object using SDO_GEOR.mosaic. It is a recommended method?

  Approach 2:

  Create the actual tiles of all images with GDAL. Is it possible to import directly the tiles with meta-information into a table of raster data?

  Thanks for your suggestions on this matter.

  Yes, for Linux, you will need to compile it yourself. I did it without too much trouble on Centos.

  But the most straightforward approach is to download and install the latest QGIS for Windows. The grouped GDAL is up-to-date and includes the hooks of the OIC.

  See you soon,.

• How to work with large number of files to a cloud export in Adobe's PDF format

  I have about 1000 PDF files to be converted to Excel.

  What means are optimal (i.e. with less manual intervention) in which I can do these tasks:

  * Download

  * convert

  * Download

  Pointers to a link will be useful. The FAQ page doesn't have this info: FAQ | Export of Adobe PDF

  I found a way to download it via a web browser and convert them via a web browser (with the help of pointing and clicking in the GUI). These methods REQUIRE the browser to be open so that the download and conversion happens - and this leads to frequent crashes / freezing of the browser windows while download / convert several files at once.

  How background sync (i.e. as in Dropbox or box etc, in which I save the files in a folder and it automatically syncs in the background) for uploading / downloading files?

  It would be great if someone can point out a optimal workflow / recommended for (conversion) handling a large number of PDF files using Adobe Document Cloud export in PDF format

  There is no best or recommended workflows. It is not designed for $ 20. Not even the product of Acrobat $500 would be 1000 PDFs without pain, but it would be a little better.

• Very large file upload > 2 GB with Adobe Flash

  Hello, anyone know how I can download very large files with Adobe Flash or how to use SWFUpload?

  Thanks in advance, any help will be much appreciated.

  If the error comes from php there is a server limit, not a flash limit.

  you will need to edit your php.ini or .htaccess file download limit.
