How to determine the size of the JVM process?
Hi,
How to determine the total process size of the JVM process (that includes Heap, Non Heap and Native memory)?
Is there any command to obtain this value on Solaris (for Sun JVM)?
I refer the process size to http://middlewaremagic.com/weblogic/wp-content/uploads/2010/11/Java_Heap_Diagram_12.jpg) here.
Many thanks for your help in advance!
Hi,
Make sure that Total Heap + Native memory will be consider as total Memory.
That means in 32 bit you will have only at most 4 GB for process + additional 2 GB for OS.
So let assume if you have 4GM RAM then out of the 4GB you can allocate 2GB as Heap and 512m as Perm in case of Hot spot and remaining will be consider as Native memory.
But in case of 64 bit will change you will have good amount of the memory so you can use plenty of Heap and Perm size.
Still if you have query let me know.
Regards,
Kal

Hello,
I am at my wits end into this. Either I am doing it the wrong way or it is not possible.
Let me explain. I need a vb script for the following scenario:
1. The script is to run on multiple Windows 7 machines (32-Bit & 64-Bit alike).
2. These are shared workstation i.e. different users login to these machines from time to time.
3. The objective of this script is to traverse through each User Profile folder and get the size of the 'My Documents' folder within each User Profile folder. This information is to be written to a
.CSV file located at C:\Temp directory on the machine.
4. This script would be pushed to all workstations from SCCM. It would be configured to execute with
System Rights
I tried the script detailed at:
http://blogs.technet.com/b/heyscriptingguy/archive/2005/03/31/how-can-i-determine-the-size-of-the-my-documents-folder.aspx
Const MY_DOCUMENTS = &H5&
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.Namespace(MY_DOCUMENTS)
Set objFolderItem = objFolder.Self
strPath = objFolderItem.Path
Set objFolder = objFSO.GetFolder(strPath)
Wscript.Echo objFolder.Size
The Wscript.Echo objFolder.Size command in the script at the above mentioned link returned the value as
'0' (zero) for the current logged on user. Although the actual size was like 30 MB or so.
I then tried the script at:
http://www.experts-exchange.com/Programming/Languages/Visual_Basic/VB_Script/Q_27869829.html
This script returns the correct value but only for the current logged-on user.
Const blnShowErrors = False
' Set up filesystem object for usage
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("WScript.Shell")
' Display desired folder sizes
Wscript.Echo "MyDocuments : " & FormatSize(FindFiles(objFSO.GetFolder(objShell.SpecialFolders("MyDocuments"))))
' Recursively tally the size of all files under a folder
' Protect against folders or files that are not accessible
Function FindFiles(objFolder)
On Error Resume Next
' List files
For Each objFile In objFolder.Files
On Error Resume Next
If Err.Number <> 0 Then ShowError "FindFiles:01", objFolder.Path
On Error Resume Next
FindFiles = FindFiles + objFile.Size
If Err.Number <> 0 Then ShowError "FindFiles:02", objFile.Path
Next
If Err.Number = 0 Then
' Recursively drill down into subfolder
For Each objSubFolder In objFolder.SubFolders
On Error Resume Next
If Err.Number <> 0 Then ShowError "FindFiles:04", objFolder.Path
FindFiles = FindFiles + FindFiles(objSubFolder)
If Err.Number <> 0 Then ShowError "FindFiles:05", objSubFolder.Path
Next
Else
ShowError "FindFiles:03", objFolder.Path
End If
End Function
' Function to format a number into typical size scales
Function FormatSize(iSize)
aLabel = Array("bytes", "KB", "MB", "GB", "TB")
For i = 0 to 4
If iSize > 1024 Then iSize = iSize / 1024 Else Exit For End If
Next
FormatSize = Round(iSize, 2) & " " & aLabel(i)
End Function
Sub ShowError(strLocation, strMessage)
If blnShowErrors Then
WScript.StdErr.WriteLine "==> ERROR at [" & strLocation & "]"
WScript.StdErr.WriteLine " Number:[" & Err.Number & "], Source:[" & Err.Source & "], Desc:[" & Err.Description & "]"
WScript.StdErr.WriteLine " " & strMessage
Err.Clear
End If
End Sub
The only part pending, is to achieve this for the 'My Documents' folder within each User Profile folder.
Is this possible?
Please help.Here are a bunch of scripts to get folder size under all circumstances. Take your pick.

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 to determine the size of The Entire iPhoto Library
Hello,
Can someone tell me if its possible to determine the entire size of my iPhoto library?
ThanksThe size of the Library when you do a "get info" for it in the finder will be larger because it includes all the data files, thumbnail files, originals and edited originals.
The size of the library when you do a "get info" of the library while within iPhoto will just give you the size of all the images.
As for my avatar I just did this;
I am not sure what picture you meant, but yes I should be there somewhere and I have 2 children and one grand daughter.
The sausage making was lots of fun.

For the life of me, I can't find out what size a photo is in terms of inches or how to change the size of the photo[s] so I can print them. I think I read somewhere to click edit, then click adjust. I don't see anything about re-sizing when I click the adjust tab: only saturation and tint levels. Thank you.
With respect to digital images, there really is no size in inches. The size is given as number of pixels horizontally and vertically. In iPhoto '09 you click the little "i" inthe lower right side of the window and it will display information related to the selected photo, including the pixel dimensions. I do not have iPhoto '11 installed so I don't know if it is the same there.
In some applications, such as preview, it has something additional called Dots per Inch (DPI) which you would think would allow you to convert the pixel dimensions to inches. It is not a real thing, though. The DPI is determined by how large or small you have chosen to print your photo and the capabilities of your printer.
There is also something called Aspect Ratio, which is usually expressed in inches x inches such as 6x9 but that doesn't mean the size on the screen or when printed is 6x9. It is the ratio of the pixel dimensions. When cropping your photos, you will have several standard aspect ratios to choose from plus any custom ones you create.
In iPhoto '09, after you choose Print, in the Print Setting window are the settings for the size you want the photo printed. You want to shoose a setting with the same aspect ratio of your photo. Otherwise, iPhoto will resize and/or crop your photo to fit the size you have chosen. -

I was using Firefox to read my Netzero email. The print suddenly dropped down to very small and I have difficulty reading the email. Netzero said to oper Mozilla Firefox, click "tools", click "options", and click "content" to change the font to a bigger size. But when I clicked the brown "Firefox" button on the Firefox page, I do not see the buttons Netzero told me to click. Can you tell me what they are referring to or just tell me how to increase the size of the font when I am reading email on Netzero. AOL email font size was not affected when I clicked AOL to read the email there.
See this and reset the zoom level there: <br />

Does any one know how to change the size of the "PARAMETER FORM" in Report6i.Hi,
You can change it in the "Parameter Form Window" property of the Report Object.
In the object navigator, select the Report object and open its property palette. Under "Parameter Form Window" you can change the "width" and "height" properties.

How to change the size of the caret in a JTextPane
I have text of different font sizes and the default caret height is the height of the text with the maximum font size. How do I change the caret height so that it matches the height of the text with the specified font size ?
This has been a real pain in the butt to figure out, but I think I finally got it. If you create your own caret (subclass of DefaultCaret) then you override its paint() and damage() methods. I was having all kinds of problems with this though. I was getting pieces of carets left behind when I moved with the arrow keys, etc... from the helps I found. The arrow keys were my big problem.
I think I finally figured out that the damage() simply does need to specify an area a little bigger than the old caret so it can blank it out. Then I think others had a logic problem, and Sun does not make this problem clear. What happens it that I think repaint() calls paint() who then uses the bigger x, y, height and width parameters that got set in damage(), which was causing my problems because the damage size was bigger than the size I wanted to create my caret with. What I do is figure out my area from the font I am using (another trick) and make them (the charWd and charHt) variables class variables. I calculate them in damage, use a bigger area to blank out my old caret in damage, and then used the correct caret size I calculated in damage() in paint(), instead of the rectangle values that seem to get passed from damage() to paint(). That was the problem in other examples.
Here is my code:

How to change the size of the scrollbar in JScrollPane?
I set a jtable in the jscrollpane,but the table is very small,so I want to change the size of the scrollbar in the jscrollpane.How can i do?Please help me,Thanks.
Dropping and re-creating the table is by far the best way (of course you need to unload the table's data to a flat file with ttBulkCp first and then reload it again afterwards).
a second option is to drop the column and re-add it with the new size but you still need to preserve the data first and put it back afterwards and this is harder for a single column than for a whole table. Also, if you are using replication you should exercise care when using ALTER TABLE to ensure iall replicated copies of the table maintain the same physical structure.

this is ridiculous! how do you keep the size of the picture for a contact in the address book that small? it is usually a piece of a lager picture... any way to make the size of the pictures the 224 KB they want? I always thought the application cropped the picture to fit their requirements...

Events are organised strictly on date and time, as read by iPhoto from the Exif data in the Photo. You cannot manually sort.
Create Albums. You can do much more organising with Albums, use Photos from different events, place them as you will. Best of all, Albums use no disk space at all. They simply reference the file on the Hard Disk. So a pic can be 1, 10 or 100 Albums with no wasted disk space whatever.
