Maximum size of a datafile

What is the maximum size we can give to a datafile?

What is the maximum size we can give to a datafile?Use this clause to determine whether the tablespace is a bigfile or smallfile tablespace. This clause overrides any default tablespace type setting for the database.
A bigfile tablespace contains only one datafile or tempfile, which can contain up to approximately 4 billion (232) blocks. The maximum size of the single datafile or tempfile is 128 terabytes (TB) for a tablespace with 32K blocks and 32TB for a tablespace with 8K blocks.
A smallfile tablespace is a traditional Oracle tablespace, which can contain 1022 datafiles or tempfiles, each of which can contain up to approximately 4 million (222) blocks.

Maximun size for a datafile

Hi,
Oracle Version :10.2.0.1
Operating system:Linux
Can any please tell me what is the maximum size that a datafile can grow and the maximum size for tablespace.
Here i am having one tablespace which is having 4 datafile in that 2 datafile are 33 gb and the other 2 datafile size are 1gb and 400 mb.But in my OEM it is showing that your tablespace ECA_DATA is 88 percent full.
I think there is no maximum size for the tablespace but why it is how it is showing the my tablespace is 88 percent full.

Hi,
Here is the output of the query which you have given.Can you pleas tell me what is the

What is the maximum possible size of a datafile...??

Hi experts,
My DB is 10.2.0.1.0 , running on AIX.
MAXDATAFILE set on the database is 200.
Now , the number of datafiles crossed 188.
SQL> select count(*) from dba_data_files;
COUNT(*)
188
Now I do not want to add any more datafiles instead I would go for resizing the same.
Please suggest what would be the maximum limit of a datafile size ?
Regards,
Chotu.

Hi..
When this error occurred was some insert into was going on in the database.It could be through SQL LOADER,IMP,IMPDP or simple insert statment.If yes, did it fail due to space issue.
Paste the output of
select FILE_ID,FILE_NAME,TABLESPACE_NAME,(BYTES/1024/1024)MB,MAXBYTES from dba_data_files where tablespace_name='tbs_name';

Oracle Database Maximum size (Linux)

What is the maximum size possible
for an Oracle Database on Linux ?
Is it limited to 2GB ? (the max file size
under Linux)
Mysql allows 4GB max, but for each table.
In fact 2GB with Linux (due to Linux
Max file size = 2GB).

Log to sqlplus as system ...
1. Create a new tablespace & datafile.
CREATE TABLESPACE "TESTSPACE" DATAFILE '/db/u01/oradata/testdata.dbf' SIZE 1000M DEFAULT STORAGE ( INITIAL 100K NEXT 2K MINEXTENTS 2 MAXEXTENTS UNLIMITED PCTINCREASE 0 ) MINIMUM EXTENT 2K
2. Then add datafiles to the tablespace as needed...
ALTER TABLESPACE "TESTSPACE" ADD DATAFILE '/db/u01/oradata/testdata2.dbf' SIZE 1000M
This will add two 1000m datafiles...
You can alter and make the files sizes larger and smaller... You can also add more files...
Also when you create tables make sure you reference them to the testspace tablespace or they will default to the user tablespace which will not be able to accomodate large data without modification.
This is really just the tip of the iceberg...
I really recommend reading the server concepts manual.

Set Maximum size for a subpanel created with splitter bars in LV8

Does anyone know how to set the Maximum size for a subpanel created with asplitter bar? If I show one cluster in the subpanel and use the scroll bar to scroll, I can see more (blank) area than I want. I just want the user to be able to scroll a cluster within a subpanel while the cluster is larger than the view area of the subpanel. I don't want to let the user scroll outside the cluster.
Ravi Beniwal

I apologize for the mixup in terminology. Please read Pane wherever the word Subpanel was used.
Please see the attached VI for a description of my problem.
I would really appreciate any help with this.

Set maximum size in Text Form Field Options for a field in bi publisher RTF

Hi All,
How to set maximum size in Text Form Field Options for a field in bi publisher RTF.
I have a RTF whch is having a field in that i need to add some validation condition but after adding certain condition in Add help text tab ,it is not accepting after certain length, how i can increase the length to unlimited,please help me on this
Thnaks

Form fields have some restrictions if your are using version lower than 11g.
They can accommodate only 393 chars. You can add the text in both status bar and help key, which can in total consume 393 chars.
If your code logic is more than that, it can be split into multiple form fields as Avinash suggested or you can use sub template logic and handle coding over there. Again in sub template code can be within/outside form fields.
So there is no option for user to increase the size of form field.

SharePoint Foundation 2010 maximum size WID

Hi,
I've installed SharePoint Foundation 2010 using the Windows Internal Database. I'm a bit confused about the maximum size of the database. On several websites I read that the max size for an SQL express database is 4GB.
Is this the same as the Windows Internal Database? Or can it grow bigger?

Are you sure you mean the Windows Internal Database? The SharePoint foundation installer will install SQL Server Express edition.

Windows Server 2008 R2 Security Event Log Maximum Size

I have a customer with logging requirements on domain controllers that are exceeding the maximum log size they have configured for the security log. When they attempted to increase the maximum size of the security event log via Group Policy, the settings
did not take effect. When an attempt was made to increase the security event log manually on the domain controller via the properties of the log, an error is generated whenever the value was changed.
The Maximum Log Size specified is not valid. It is too large or too small. The Maximum Log Size will be set to the following: 196608 KB
The 196608 KB value is the value that it is currently set at. Testing on other logs, application, system, has lead to the same result.
wevtutil.exe sl security /ms:<n> produces similar results. There is no error message given but the value doesn't change when you run wevtutil.exe gl security
When viewing the registry value MaxSize under HKLM\Current Control Set\Services\EventLog\Security the change is reflected, but the log does not seem to get any larger.
What one would expect to be a two minute change in a group policy object has turned into something much more difficult. Any idea what could be causing this?
Joseph M. Durnal MCM: Exchange 2010 MCITP: Enterprise Messaging Administrator, Exchange 2010 MCITP: Enterprise Messaging Administrator, MCITP: Enterprise Administrator

I verified that it was not another policy - the domain is pretty simple without many policies, only policies applied are:
Default Domain Policy (no event log settings)
Company Domain Policy (no event log settings)
Default Domain Controller Policy (no event logs settings)
Company Domain Controller Policy (...\Event Log\Maximum security log size 4194240 kilobytes)
The value was 196608 before, the plan was to change the group policy setting to 4194240 and I expected it to be that easy. However, the values didn't change.
4194240 is divisible by 64
Used multiple tools to try and change
Group Policy
Event Viewer
wevtutil.exe
registry editor
While some of the methods display a larger event log, the actual size of the event log still seems to be limited to 196608 kb.
Thanks,
Joe

How can i increase the maximum size of a text column in Access

hello,
i am inserting data in the MS-Access database through my servlet and am getting the exception whenever the length of the text data is more than 255 characters as in Access the maximum size for character data column is 255 can anyone tell me if there is any way by which i can increase the maximum limit of the column size in Access ,i.e. to make it more than 255.

A text field in Access has a maximum size of 255 characters. If you want to store text information in Access larger than 255, you need to use the memo rather than text data type. There are special considerations for using an Access memo data type and accessing it through JDBC. Specifically, I believe it must be accessed as a binary object (BLOB), rather than text when using the JDBC-ODBC bridge. There are lots of discussions within these forums regarding how to manage, and the issues with using the Access memo data type.
Good luck!

I want to set a maximum size for pictures when FF shows websites. How can i do that? NO I DONT MEAN "HOW TO ZOOM".

I have FF 34 but this problem has been there for a lot of earlier versions. On many webpages there are pictures that cover my whole screen, and I want to set maximum size for showing images on webpages.
I ONLY wanr to change the maximum size of the images, AND IAM NOT asking about how to zoom the webpage.

Do you want to hide large images or merely make them smaller by setting a max-width and max-height?
You would probably have to use JavaScript (bookmarklet) to achieve this reliably.
There are bookmarklets to make large images fit in the window to avoid a horizontal scroll bar
You can try this code in the userContent.css file (adjust the max-width accordingly).
*http://kb.mozillazine.org/userContent.css
<pre><nowiki>img { max-width: 1024px !important; height: auto !important; }</nowiki></pre>
The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.
*http://kb.mozillazine.org/Editing_configuration
*Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
*Use a plain text editor like Notepad to create a (new) userContent.css file in the chrome folder (file name is case sensitive)
*Paste the code in the userContent.css file in the editor window
*Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userContent.css. Otherwise Windows may add a hidden .txt file extension and you end up with a not working userContent.css.txt file

Forms: How to set a maximum size in Text Fields with automatic size

¡Hi!
When I set a text field on my forms and I use automatic size for te text that the user can write, if the user don't need more space than the field size, when the text appears, Adobe Acrobat Pro always set the text-size to 14 or higher. How can I set a maximum size for that text? For example... 12 or 10...
Thank you very much,
Best regards from Spain,
David.

Ok. If I use a single line text field, changing the height of the field seems to be a simple way to solve the problem, but... what should I do when the fields are multi-lineal?
Thanx for your quick answer.

How to restrict the maximum size of a java.awt.ScrollPane

Dear all,
I would like to implement a scroll pane which is resizable, but not to a size exceeding the maximum size of the java.awt.Canvas that it contains.
I've sort of managed to do this by writing a subclass of java.awt.ScrollPane which implements java.awt.event.ComponentListener and has a componentResized method that checks whether the ScrollPane's viewport width (height) exceeds the content's preferred size, and if so, resizes the pane appropriately (see code below).
It seems to me, however, that there ought to be a simpler way to achieve this.
One slightly weird thing is that when the downsizing of the pane happens, the content can once be moved to the left by sliding the horizontal scrollbar, but not by clicking on the arrows. This causes one column of gray pixels to disappear and the rightmost column of the content to appear; subsequent actions on the scrollbar does not have any further effect. Likewise, the vertical scrollbar can also be moved up once.
Also, I would like a java.awt.Frame containing such a restrictedly resizable scrollpane, such that the Frame cannot be resized by the user such that its inside is larger than the maximum size of the scrollpane. The difficulty I encountered with that is that setSize on a Frame appears to set the size of the window including the decorations provided by the window manager (fvwm2, if that matters), and I haven't been able to find anything similar to getViewportSize, which would let me find out the size of the area inside the Frame which is available for the scrollpane which the frame contains.
Thanks in advance for hints and advice.
Here's the code of the componentResized method:
public void componentResized(java.awt.event.ComponentEvent e)
 java.awt.Dimension contentSize = this.content.getPreferredSize();
 this.content.setSize(contentSize);
 java.awt.Dimension viewportSize = getViewportSize();
 System.err.println("MaxSizeScrollPane: contentSize = " + contentSize);
 System.err.println("MaxSizeScrollPane: viewportSize = " + viewportSize);
 int dx = Math.max(0, (int) (viewportSize.getWidth() - contentSize.getWidth()));
 int dy = Math.max(0, (int) (viewportSize.getHeight() - contentSize.getHeight()));
 System.err.println("MaxSizeScrollPane: dx = " + dx + ", dy = " + dy);
 if ((dx > 0) || (dy > 0))
 java.awt.Dimension currentSize = getSize();
 System.err.println("MaxSizeScrollPane: currentSize = " + currentSize);
 setSize(new java.awt.Dimension(((int) currentSize.getWidth()) - dx, ((int) currentSize.getHeight()) - dy));
 System.err.println();
}Best regards, Jan
