What is reading\writing on my HDD ???

who\what is reading\writing on my HDD slowing down my mac ???
Some times my mac slows without lot of cpu load but I can hear my internal disk working a lot...
I try to discover what process is using my disk but on activity monitor I am not able to see nothing... I've tried atmonitor but nothing... on istatmenu you can see global disk activity (high) but not by process ...
Is there a way to see on activity monitor or 3rd party monitor I\O activity like on MSwindows or Linux?
also on: http://discussions.apple.com/thread.jspa?threadID=2420234&tstart=0
andon : http://discussions.apple.com/thread.jspa?threadID=2427487&tstart=0
but without answers...
Is it possible that in mac os x 10.6.4 there is no way to monitor what process is spinning mi disk ?
Any tips ?

*OS X* has support for DTrace. There are a few shell scripts available such as iofileb and iotop, and for a GUI application, there is Instruments if you have the *Developer Tools* installed.

Error reading/writing file message when opening garageband and/or files

I've been recently getting this message when I open garageband and files
"Error reading/writing file\U201Ccom.apple.garageband.cs\U201D
I've been in and repaired disk permissions and all that it says it is all fine, reinstall garageband and message still comes up, weird.
not only is garageband being a nuisance, Mac OS X 10.6.2 is being a pain when shutting down telling me to restart the computer. This only happened since upgrading to 10.6. No one as yet knows this promble so I'm gonna have to ring apple and see what is going on here.
and also my other problem is that mac doesn't seem as snappy anymore I noticed this before upgrading to 10.6 and made no difference when "cleanly" installing 10.6. I get a colour wheel popping up and i'm having to wait with simple tasks. iMac only 2 years old.

i give up with this discussion forum no no one knows anything

Stax reading /writing need help from xml guru plz

hi, i have been told that stax reading /writing should involve no overhead and that is why i use it and i am now able to write my large data to file, but using my reader i seem to run out of memory, using netbeans profiler i ahve found that char[] seems to be the problem,
by backtracing i ahve found that javax.xml.parser.SAXParser.parse calls the xerces packages which eventually leads to the char[ ], now my code for my reader is attatched here...

}i thought it may have been a recursive problme, hence having so many instance variables instead of local ones but that hasn't helped.
all i need at the end of this is a Collection which holds an array of testCollections, which holds an array of cCounts and i was able to hold all of this in memory as all i am loading is what was in memory before it was written.
can someone plz help
ps when i use tail in unix to read the end of the xml file it doesnt work correctly as i cannot specify the number of lines to show, it shows all of the file as thought it is not split into lines or contains new line chars or anything, it is stored as one long stream, is this correct??

please if anyone has any ideas from this code why a char[] would use 50% of the memory taken, and that the average age seems to show that the same one continues to grow..
thanks in advance
danny =)

hi, i am still having lo luck with reading the xml data back into memory, as i have said before, the netbeans profiler is telling me it is a char[] that is using 50% of the memory but i cannot see how a char[] is created, my code doesn't so it must be the xml code...plz help

I like the mail feature with one exception; I cannot figure out how to change the font size of incoming mail permanently. And, when answering an email I have to highlight the first few words and zoom it so I can see what I am writing. what am I missing?

I like the mail feature with one exception; I cannot figure out how to change the font size of incoming mail permanently. And, when answering an email I have to highlight the first few words and zoom it so I can see what I am writing. what am I missing?

You can type the email using what you set in preferences and then highlight the text and use command - minus sign (or command - + for larger) to reduce the size of the text.
You can also type command - T and a window will appear allowing you to select fonts/sizes/color/ background highlight.
The above works in Notes also. I haven't tried to do this in any other Apple application.
For incoming emails, you can use the above to reduce font size, but I don't know of a way to permanently set the incoming font size to a default.

Reading & writing from MS Excel files in Webdynpro ABAP

Dear experts,
We have a requirement to read and write from an MS excel file in a Webdynpro ABAP based application. The application would be deployed on WAS (Web Application Server) which is running as part of SAP ECC on UNIX platform.
What is not clear is
1) If we store the MS Excel template on the server which has UNIX, will the file be recognised for reading/writing programmatically in Webdynpro ABAP? If this works, we have a requirement where the end users will download the excel template and upload the same after filling data into the excel file. The data filled into the excel has to be read and updated in the SAP backend (ECC).
2) There is an article on "Modifying Excel using WD ABAP" at the following link
https://wiki.sdn.sap.com/wiki/display/WDABAP/ModifyingexistingexcelsheetusingWDABAP
But again it is not clear whether this approach will work on Unix based SAP server (ECC WAS).
Thanks
Suresh

I don't know if there is an application in Unix that can read Excel files - if that is what you are asking. However that has nothing to do with this forum. If you are uploading the file to ABAP using Web Dynpro ABAP, then it doesn't matter what Operating System the server is running on. Unix, Linux, Windows - all the processing is done in ABAP and is OS independent. The actual reading of the file in ABAP involves reading either an XML or Text Tab Delimited version of the Excel file however - if you read through the links on manipulating Excel in ABAP.

App for editing/reading/writing Excel, Word, Windows notepad text documents

I was wondering if any of you's could recommend some apps (from experience) that would allow me to, edit/read/write Excel, Word, Windows notepad text documents.
I could make do with an app that would do the above but without the ability to create, edit Windows notepad text documents. But been able to read, write, edit Word and Excel documents would have to be a must.
Thanks in advance.

Thanks everyone for the help it was much appreciated.
After debating, I decided on Docs To Go at £9.99. For this amount its a universal app and as such I can have it installed on my iPhone as well as my iPad (which is what I have done), so £5 for to have it on each device is good value I feel. Quick Office on the other hand would have cost £8.99 for the iPad version and £5.99 for the iPhone version a total of almost £15, which is quite a bit more than I paid for Docs To Go.
Upto now, I find Docs To Go does everything I want from it, with regards to editing, reading, writing my Excel files. I tried transferring a Microsoft Windows Notepad text document over to the iPad/iPhone, I was able to read this and also add additional text/words to it and save it too. I do use text documents sometimes because if I want to add them onto a friend's computer for example, I know that they will be able to read them because with them having a Windows PC and also my friend does not have the Microsoft Office program on their PC.
The transferring of files from the computer to the iPhone/iPad is done via a free download of the Docs To Go desktop software program (which is both PC and Mac) compatible). You first need to go into the Docs To Go app and select 'ADD DESKTOP'. This then allows you to add a device to the Docs To Go desktop program thus enabling transfer. You are shown a pin number on the screen which you enter into the Docs To Go app, this procedure only needs to be done once.
The Docs To Go desktop program creates a folder during installation, where all the files etc are stored that are transferred/going to be transferred over are kept.
Some people might think needing to use a program to transfer files over is a bit of a nuisance, when other similar programs allow transfer via a web browser. Personally I find that those programs, the transfer is a bit cumbersome and can be a bit slow. I find the transfer via the Docs To Go desktop program is a lot easier and faster than using the web browser. The only downside I can see with needing to use the Docs To Go desktop program is that.. If I am at a friend's house and want to transfer something on to my iPhone/iPad. My friend would need to install the program, but saying that, its a very small program and its not a big deal having to install it. If they didn't want to install it, then there is either emailing the file or transferring the file to my Dropbox account. I forgot to mention that Docs To Go supports cloud/online storage such as Dropbox, GoogleDocs as well as others.
Once the above is done, you switch the wifi on, load the Docs To Go app, load the Docs To Go desktop program. You then just drag and drop the folders etc that you are wanting transferred over into the The Docs To Go desktop program, then you click on the circular arrow button and they are then transferred over onto the iPhone/iPad.
Once on the iPhone/iPad, you can view them, add additional information, when you make any changes you can press the circular arrow symbol (bottom left of the Docs To Go app) on the Docs To Go app and the changes are then synced back to the same file that is stored on the computer, so its very easy to keep everything in sync and up to date.
It is possible whilst using a Microsoft Word document to have a word count, you just touch the symbol at the bottom right of the Docs To Go app and choose Word Count from the drop down menu. I have heard a few people in some reviews saying that 'Docs To Go doesn't have a word count', when indeed it does.
One surprise is that Docs To Go, does not have a spell checker, but hopefully during later updates, the feature might be added. I sent my feedback to Docs To Go requesting this feature on future releases. I expect that there will be many other people who have requested this feature too.
I just thought I would share my experience with using Docs To Go.
Thanks again everyone for the help, it was much appreciated

Why is it when Im responding to a text and a new text comes in I lose what I was writing in IOS 8

Why is it when Im responding to a text and a new text comes in I lose what I was writing in IOS 8.

Syncing shouldn't trouch you photos unless you have photos in a Photo Library album. These would be photos that were synced to your phone from your computer. If you do have any, you'll need to use an app like PhotoSync to transfer them to your computer prior to syncing.
If you prefer to backup your camera roll photos prior to syncing, open iTunes and go to Preferences>Devices and check "Prevent...from syncing automatically". Then connect your phone to your computer and import them as explained here: http://support.apple.com/kb/HT4083.
Then, to minimize data loss, follow the steps in this user tip: https://discussions.apple.com/docs/DOC-3141. To follow the steps, first open iTunes and go to View>Show Sidebar. Also, Transfer Purchases is now located in File>Devices.

Efficiency of reading/writing files character-by-character

I've been assuming that when I do a file "open for access," that among the housekeeping functions set up behind the scenes, there is some sort of buffer created, the size of which is somehow related to the logical sector size of the disc in question, so that reading or writing short pieces of text, or even single characters, doesn't cause independent physical read/write actions at the disc drive.
Does anyone know if this is true or false? Maybe the question would be clearer posed another way. Suppose I set up a loop to read or write 1024 characters, sequentially, but one at a time. Obviously the loop will require much more time to execute than a singe read or write statement calling for 1K of text all at once. But will there be significantly more activity at the disc drive itself? Will the data be read or written on 1024 successive spins of the platter, or will it be buffered down to one spin, or maybe a couple, depending on the exact location of sector boundaries and so on?
Thanks.

Thanks for this. I was sure some such facility was in operation, but I couldn't find anything explicit on the question. I have a task in which I'm trying to convert what looks like incredibly badly formed XML application files into properly tagged and well-formed XML so that I can then get them through a well-designed XML parser. To decode these utter shambles requires decision logic that goes nearly character-by-character. One tutorial page I found on Applescript file I/O suggested that reading/writing character-by-character was inherently inefficient, which I can see that it is, I just wanted to make sure the inefficiency didn't go all the way down to the mechanics of kicking the disc for every single character. The description in the tutorial was ambiguous, and a little disconcerting.
The tutorial also suggested an alternative strategy of reading an entire file at once into a string and then working with the string. But my files are megabytes long, and I wonder how efficient operations are on megabyte strings, presuming there isn't a limit on string length. Short of trying to do some complex adaptive algorithm, which I might never get working right, I'm pretty sure that keeping to the KISS principal, and just going character-by-character, is a near-optimal strategy in my case.
Cheers.

Performance issue: Tuning Reading/Writing to a Socket.

I have use case where reading/writing to a Socket is spending over 25% of the time in NativeThread.current() (Called from within SocketChannelImpl) This is a native call and it occurred to me that there might be a Java JNI option which could improve this call in particular.
This may be hprof giving incorrect information, but I don't know how to provide this. YourKit also shows this method as a big hit.
I am not so worried about read0 and write0 as this is directly related to what the use case does.
Can anyone suggest tuning options which might improve the performance of this call?
Does anyone know a way to determine if the information regarding this call is accurate?

I would ignore it. All it does is:
'Returns an opaque token representing the native thread underlying the invoking Java thread. On systems that do not require signalling, this method always returns -1.'I think the significant thing is that it is called while synchronized on 'stateLock', so if you have > 1 thread executing writes, the entire sync block will tend to be a bottleneck. I would aggregate the data for current() and read0(), or current() and write0(), and treat it all as I/O time.

Reading & Writing from/to OCR

Hi,
Is there a way to read and write the Oracle Cluster Registry.
Are there any API's available for the same.
Thanks

whatis wrote:
I have a SW application running on all nodes in the RAC Cluster.
The SW needs to write data to a place which is visible to all and can be read by all the other nodes. Also it should be able to gather information (especially about failover), so should be able to read from it.The OCR is not used to as a common data store for CRS applications - that is typically what a cluster file system is used for. This allows the same set of directories and files to be visible to applications on each and every cluster node.
The OCR is specific to CRS and should only be used by CRS software.
I found this link on the internet 'C Application Programming Interface to Oracle Clusterware'
http://download.oracle.com/docs/cd/B28359_01/rac.111/b28255/crsref.htm#CHECGHGI
Yes, if you want to create a cluster application that you want to be managed via CRS. But this requires more thought than simply slapping a few calls together in an application to make it cluster enabled.
Is this the correct way to do it? Can reading/writing from/to OCR lead to fatal errors?Unsure whether it is the correct way for the problem you're trying to solve as that problem is pretty still much unknown to us as you have not described it.
Can one corrupt the OCR? Not if the API calls are used and used correctly.
It is a bit strange to see a posting about using the CRS API itself - usually we write our software in the RAC layer (as PL/SQL and Java stored procedures, using the cluster features of the database instances).
Do you intend to only use CRS? Or CRS with ASM and RAC? And why do you want external C application code to make use of cluster services?

HD is always reading/writing

My iMac HD seems to always be reading and or writing even when nothing is open. I did the activity monitor and watched the disk activity and just about everything showed 0.0 cpu. My data read/write sec. seem to stay steady around 200kb each. I can hear the HD reading/writing, nothing bad sounding but its always doing it. I've done both disk repair and and permissions as well as booting up from the install disc and repairing. everything said it was normal, no issues. I don't get what's wrong. I'm scared my HD is crashing or something. Can anyone help suggest anything?

Check to see if you are viewing all processes and not just my processes. Could the sound be caused by something other than the hard drive like maybe one of the fans? Do you have any anti-virus software installed?
Some things you can try:
Try booting into safe mode and see if it still happens.
http://support.apple.com/kb/HT1455
Go to System Preferences/Software Updates and un-check the box to download important updates automatically.
Look in the upper right hand corner at the spotlight and see if it is indexing the drive.
In Activity Monitor click on Network and see if there is anything continuously going in or out.

Logic froze while I was working on something so I forced quit. Now every time I open LOGIC a message pops up that says:
"Error reading/writing file
“com.apple.logic.pro.cs”:
Logical end-of-file reached during read operation."
The only button option is cancel so I press it and another message appears that says:
"The Preferences are not loaded completely.
Do not save them, as you would overwrite the Preferences file with incomplete data."
Then when i close logic a box appears saying:
"The Preferences are not loaded completely.
Save them to "com.apple.logic.pro.cs" anyway?"
There are 3 button options to press; ok, cancel or dont save.
I press "don’t save" cuz I don't want to ruin anything.
I found a discussion located here: https://discussions.apple.com/message/9564253#9564253 that says if I delete the file "com.apple.logic.pro.cs" it will resolve the problem. If I do this will I loose or mess anything up at all, automation, saved channel strips customizations, saved effects, synth, or ultrabeat customizations etc? Or especially will I loose any work I've done? I have hundreds pieces of music files I've created. I'm scared to mess anything up with all the hours and months of work I've done. Is there anyway to fix this without loosing anything? I'm using Logic Pro 8.
Thank you

You can safely delete this file - its the preference file for control surface settings - you haven't said whether you're actually using a control surface or not, if so, you will have to set it up again. A new file will be created when you fire Logic up again, but of course it will contain default settings. If you have a complicated control surface setup, remember to keep a backup copy somewhere in case any future problems arise.
Other than that, you really have nothing to be scared about - hopefully your problem is as simple as that and there isn't an underlying problem (a corrupt hard drive, for example). You seem concerned about losing work, so I guess you want to think about backing that up on a regular basis too. If you're saving your projects to your system drive, do get an external one for this. And also check that you have plent of free space on your system drive - you need to keep about a quarter or third of it free for your OS and programs to run properly (some temporarily stored files can be quite large).

My magic mouse isn't scrolling on my imac. I have leopard 10.5.8 from what I read it should work.

Please help me.
I just bought a Magic mouse and it's not working.
From what I read it is supposed to work on leopard 10.5.8. Which I have.
The mouse is working but the scrolling isn't. I can't scroll at all

Leopard required a Wireless Mouse software update. See if Software Update offers this.

Reading/Writing .xlsx files using Webdynpro for Java

Dear All
I have a requirement to read/write excel files in .xlsx format. I am good in doing it with .xls format using jxl.jar. The jxl.jar doesn't support .xlsx format. Kindly help me in understanding how do I need to proceed on reading/writing .xlsx files using Webdynpro for Java.
Thanks and Regards
Ramamoorthy D

i am using jdk 1.6.22 and IBM WebSphere
when i use poi-3.6-20091214.jar and poi-ooxml-3.6-20091214.jar to read .xlsx file. but i am getting following errors
The project was not built since its classpath is incomplete. Cannot find the class
file for java.lang.Iterable. Fix the classpath then try rebuilding this project.
This compilation unit indirectly references the missing type java.lang.Iterable
(typically some required class file is referencing a type outside the classpath)
how can i resolve it
here is the code that i have used
public class HomeAction extends DispatchAction {
     public ActionForward addpage(
                         ActionMapping mapping,
                         ActionForm form,
                         HttpServletRequest request,
                         HttpServletResponse response)
                         throws Exception {
                         String name = "C:/Documents and Settings/bharath/Desktop/Book1.xlsx";
           FileInputStream fis = null;
           try {
               Object workbook = null;
                fis = new FileInputStream(name);
                XSSFWorkbook wb = new XSSFWorkbook(fis);
                XSSFSheet sheet = (XSSFSheet) wb.getSheetAt(0);
                Iterator rows = sheet.rowIterator();
                int number=sheet.getLastRowNum();
                System.out.println(" number of rows"+ number);
                while (rows.hasNext())
                    XSSFRow row = ((XSSFRow) rows.next());
                    Iterator cells = row.cellIterator();
                    while(cells.hasNext())
                XSSFCell cell = (XSSFCell) cells.next();
                String Value=cell.getStringCellValue();
                System.out.println(Value);
           } catch (IOException e) {
                e.printStackTrace();
           } finally {
                if (fis != null) {
                     fis.close();
            return mapping.findForward("returnjsp");
