Hi,

Used of datafile size is 750 MB for each datafile ...
Can we reduce a datafile size from 8GB to 2GB !
while it is use to store data around 750 MB data ..
If it allow will impcat on my data ???
SSM

If used amount is 750MB then yes you can resize to 2G.
Try issueing the following (example)
SQL> alter database datafile 'c:\oracle\ora92\ORCL\userdata01.dbf' resize 2000m;
If it is not possible, oracle will complain with error number ORA-03297.

My ipad3 can't reduce photo size for email.

Here's two apps you can use or get Apple's iPhoto for the new iPad.

How can I reduce the size of a pdf file for emailing?

I want to send a pdf file which is 8 mb, it has bounced in an email because it is too big, how can I reduce the size of the pdf file for emailing?

Sometimes a simple "Save As" will reduce the file size slightly, but probably not enough to pass the <8 mb threshold of your recipient, as you need.
You've probably seen it, try the next option in the Save As menu, "Reduced Size PDF," and make it compatible with the latest version possible, again considering the recipient. This suggestion assumes Acrobat X. You don't say which version you're using, but this tool was available at least going back to Version 8, but in a different place, you'll have to hunt.
If all that doesn't work, you could remove some images from the source document, which also will reduce the overall size.
Best luck.

Can we reduce the SIZE of the text in TEXT Module?..Smart form

Hello,
Can we reduce the size of the TEXT module in Smart form.
As the text that I am putting in the Text Module is taking more space and it is displaying in the next page.
What are the steps that I can take to display the text in the same page.

Kittu

Hi,
you can do these by two ways,
1-> By reducing the font size
2-> reducing the line spacing
both can be adjust in Smart Style what you are using.
If you not using any style for this, default style will take.

How can I reduce the size of "Other" usage?

I unable to update my IOS because "Other" memory usage is too high and I have insufficient memory available for the upgrade. What does other include and how can I reduce its size?

You can update using iTunes on your computer, which will bypass the space requirement that is imposed on over the air downloads.
To reduce the size of other, back up the phone, restore it using iTunes, then restore your backup. That should get it down to a reasonable size.

How can I reduce the size of the jvm?

I would like to decrease the size of a jvm; I've found a program that makes it, but you don't know how does it works (and you have to pay for it), I'm talking about VM Optimizer 2.0, from Invirtus.
Can anyone tell me how can I reduce the size of the jvm?
Thanks a lot.

I assume you mean the size of a JVM instance in memory and not the size of the JRE which is on the disk.
I don't believe that there is any way at present for your Java code to change the amount of memory available to the JVM. This shouldn't matter too much, though. Firstly, you can control the size of the JVM from the command prompt with the -Xms and -Xmx options. Secondly, any remotely reasonable operating system is going to wait until the JVM has requested memory before allocating all of it. If you start a JVM with a 2Gb heap, it does not occupy 2Gb of physical memory straight away.
Finally, I did a Google on InVirtus VM Optimizer and must request some information. What does that software have to do with Java? It's designed to reduce the size of a virtual computer as created by a prorgam such as VMWare. It has nothing to do with the Java virtual machine.

How can I reduce the size of some apps like Facebook, Twitter,whatsup..etc..as they eat a lot of space on my iPhone 4s ?

Its frustrating. I also have this problem with Dropbox, a great service but they dont have a 'delete cache' button. Dropbox told me to log out and back in again but nothing. If i delete the Dropbox app (And Facebook app and Twitter) and then re-install its back to its original size
If you go into settings/general/usage and see all the apps, press the app for Twitter (Or Facebook) and you'll see how much extra the app is keeping under 'Documents & Data'
Delete those apps and re-install and the documents and data will be 0 and the app back to normal.
Its frustrating as some of these apps can get huge, after viewing a video my facebook app went up to 450 meg ! Same for twitter. I tend to use 'Twiterrific' as the app size doesnt get silly unlike the official Twitter app

How can I reduce the size of a photo proportionally. With my old Mac mini I was able to place the pointer on the bottom right corner hold the shift key until I achieved the desires size.

How can I reduce the size of a photo PROPORTIONALLY? With my old Macmini I was able to place the pointer on the bottom right corner of the picture, hold down the shift key and move the pointer to achieve the desired size.

You'll need to use a 3rd party editor like one of these:
Some Image Editors That Support layers:
Photoshop Elements 11 for Mac - $79
Rainbow Painter - $30
Imagerie - $38
Acorn - $50
Pixelmator - $60
Seashore - Free
Portraits and Prints - Free
GIMP for Mac - Free
Xee 2.1 - free
My personal preference would be for Photoshop Elements for Mac. Most of these will let you select and copy a head from one photo, paste it into another photo, resize and place where you need it.
PSE has a specific feature just for that function. I belive the Adobe site for PSE has a demo video of that feature.

In general theory, one now has the Edit button for their posts, until someone/anyone Replies to it. I've had Edit available for weeks, as opposed to the old forum's ~ 30 mins.
That, however, is in theory. I've posted, and immediately seen something that needed editing, only to find NO Replies, yet the Edit button is no longer available, only seconds later. Still, in that same thread, I'd have the Edit button from older posts, to which there had also been no Replies even after several days/weeks. Found one that had to be over a month old, and Edit was still there.
Do not know the why/how of this behavior. At first, I thought that maybe there WAS a Reply, that "ate" my Edit button, but had not Refreshed on my screen. Refresh still showed no Replies, just no Edit either. In those cases, I just Reply and mention the [Edit].
Also, it seems that the buttons get very scrambled at times, and Refresh does not always clear that up. I end up clicking where I "think" the right button should be and hope for the best. Seems that when the buttons do bunch up they can appear at random around the page, often three atop one another, and maybe one way the heck out in left-field.
While I'm on a role, it would be nice to be able to switch between Flattened and Threaded Views on the fly. Each has a use, and having to go to Options and then come back down to the thread is a very slow process. Jive is probably incapable of this, but I can dream.

What format are they? Tiif? Jpeg? You can compress them with a lot of apps - including Preivew and just about any graphics editor out there. I'm not sure that 45mb would crash iPhoto thogh, are yo sure that's the cause? I know that some folks have mentioned pixel dimensions causing issues, as can color profiles.

Why is my word and pdf files so large? How can I reduce the size?

My document contains mostly photos from a database via a path to the actual jpeg photos on disk.
There are 39 jpeg photos + a small amount of text with each photo.
The 39 jpeg photos on the disk add up to be 5.79 mb.
If I export the crystal reports document as [Microsoft Word (97-2003) Non Editable] the, the file size is 36.8 mb.
If I export the same data as a [Microsoft Word (97-2003) Editable] the file size is only 3.1 mb.
That is a difference of 33.7 mb! Why?
Also, when I export the same data to a PDF file it is much larger than I think it should be; 12.7 mb.
Why is my word and PDF files so large?
How can I reduce the size of the word and PDF files? (without reducing the photo quality).
Are there any tools to post process the Word or PDF files to reduce the file size?

You can't, extra size is to hold the details

Upto how much I can set maximum Heap size for jvm?

I am running application on 8GB RAM Windows 64 bits machine.
I am running out of OutOfMemory (Heap Space). I want to increase the Heap Size for my jvm.
But can anybody please tell me what is the limit by which I can set the maximum size for heap?
Thanks in Advance,
Jenish

Max allowed memory per process is 2 raised to the 64th power. What maximum memory you can set depends on the memory available
for your application. You may be able to set more than 8GB ram then it will use the swap space and it will slow down your application
performance. So try different memory size and see which one works best for your application.
