JProbe memory debugging help.

Hi,
I have a swing application, with some complicated dialogs, with a lot of listeners, and i realized that they are not being gc'd. So i have started using WeakReferences for listeners and inner classes, however, i am still having trouble.
I am using JProbe's memory debugger, but i am having trouble reading the referrer tree.
is anyone familiar with this application that could lend a helping hand.
my problem is that looking at the tree, i dont know which referrers i need to explicitly take care of, and which of them will be taken care of by the gc.
In addition, i am having trouble reading the tree....for example:
here is a copy of my referrer tree:
http://www.cs.ucsb.edu/~arash/mem.htm
I don't know where to go from here. I am pretty sure i can ignore recursive items, and items marked referent....but from there i am lost.
any help is greatly appreciated. thanks!

WeakReferences are cleaned up whenever the gc feels like it not just when it needs to. Use SoftReferences instead.
However in you case I would not use them at all as the GC can still remove object you still need,
You cannot assume the GC will clean up references. If there is a reference to the object it keeps it. YOU need to remove the reference when it is no longer required.
For the objects you expect to be gced but are not, you need to ensure there are no references to them.

Jprobe Memory Debugger with Entity Bean

hi,
I m testing an EJB application(Bean Managed) using Jprobe Memory debugger.
While testing it gives me that objects referred by entity bean are loitering . for eg if somewhere in my code i created an integer using new Integer and if I m letting it passed to ejbCreate .then that object is pointed as loitering while debugging. further it happens with srtring and data access Objects and otheres as well.
so is there a memory Leak or The debugger is handling the entity bean in such a way.
version of jprobe used is 5.2.3 on windows
Please provide me help regarding the same

Actually, what one or the developers in my group found out is two things:
1) The clone is a shallow copy.They copy the references but not objects themselves. This has been causing problems for us.
2) It seems that you don't work on a copy and you work on the original and they keep a copy. Now, this is fine IF you don't have multiple threads working on the same Entity bean and we moved our application from Weblogic where it throws an exception if that Entity bean is in use to OC4J which is suppose to copy the bean and doesn't so you have multiple threads possibly modifying the same object.

No other choice, you have to restore to use your iPad.

How do debug an application in Shared Memory debug mode using JDev

I don't see the option of using "Shared memory" debug mode in JDev. There is only socket debug option(Attach/Listen) in debugger but no shared memory debug option.
Is it missing or is it hidden somewhere.
Can anyone let me know as all IDEs provide that.

Any updates?

EP Memory Consumption - Help!

Greetings SAP'ers,
We are running a few WebDynpros (ESS Travel & Expenses and one custom Java Dynpro) as well as some PCD content in a production environment. We have a huge amount of resources available to run this: four servers running 5 JVM's with 2GB of memory available to each -- and we are still running out of memory when traffic gets heavy! And by "heavy," I mean only about 450 active sessions for half that many users.
This is completely different than I am used to; we run almost 20 other high-load applications in a "regular" Java environment with just two JVM's at 160MB each. So my questions are:
- What can we do to reduce resource consumption? Any ideas are appreciated. Is there a magic parameter I should look at?
- Is this resource consumption consistent with what you observe on your Portal?
- I have a gut feeling that it is ESS Travel & Expenses that is the primary resource user. Does anyone else running T&E see this behavior?
- Is there a particular report I can view to see which Dynpro is the main resource user?
- Last time I analyzed a heap dump, it looked like ApplicationSessions were the culprit. Lowering the timeout value for WebDynpro sessions helped a lot, but not enough. Is there a way to reduce the resources consumed by a user's session?
Your input is much appreciated!!!

Hi,
Could you confirm that you've have the max heap size set to 2GB for the JVM parameters (not only that the server contains 2GB of RAM). Since you have 64 bit, this should be no problems.
Have a look at this document on how to debug webdynpro and especially the Distributed Session Management (DSM) which is the key to closing sessions when the user navigates away from the application
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d0cb32c5-36a7-2910-2c9b-ba4a5bbdbb56
If no webdynpro sessions are terminated before 4 hours of inactivity, this could explain your problems (I am not sure how ESS/MSS handles this, but I would belive it had some mechanism).
I would also recommend doing a sizing either through quicksizer (https://websmp108.sap-ag.de/quicksizer) or through a sizing expert (either Hardware partner or SAP)

Snow Leopard 'error code 50', 'Low Application memory'. Help.

Hi.
I've been facing **** lot of problems with my MBP of late, and all that I could try have turned unfruitful. I'd appreciate some help.
Problems started when I downloaded and tried to install SL update 10.6.7 on 10.6.6. It was working fine on 10.6.6. The update failed, and I received 'error code 50' very often while deleting files from Trash. Also, 'beach-balling' became more frequent, and I had to force quit applications very often because of 'low application memory' box being displayed.I also encountered the grey screen prompting me to 'press power button till shut down and restart'.
Finally, I tried a clean reinstall but the same problems persisted, and lots of applications stopped working. I could not download files from browser (Low disk space, despite a 100 GB space available on he HD) or save textedit, Office or iWork files. I did a clean reinstall again, with zero-erase option and again downloaded the 10.6.7 combo update. The 'Software Update' application failed. I downloaded the update from my browser and it was installed successfully finally after 4 system restarts, but the 'error code 50' problem still persists.
What am I doing wrong? I've been dealing with this abnormal performance for more than a month. I haven't backed up files because there is no use making a backup of corrupt system. Specs : MBP'09, 13.3". 2.26 GHz, 160 GM, SL 10.6.7.
Please advice.
Regards.

I tried to run the hardware test by inserting the Applications Install dvd and pressing 'D' just after the chime. It did not run. Nevertheless, the App DVD is ejected every time I insert it in to install some apps, like iLife etc. Running Disk Utility dies not work, as it says the 'disk cannot be mounted'.
I tried another clean reinstall of SL 10.6, and some of the funny stuff are :
1. error code 50 yet again
2. It won't allow me take snapshots, saying 'You do not have permission to save snapshots etc.."
3. Safari cannot download files
4. 'Low Application Memory' message box appeared a few times, prompting me to Force Quit Safari.
Could there be something wrong with the Install DVD? Though Disk Utility First Aid shows error free HD verification.

Unable to run Memory profiling, help please

Hi there,
I installed the lastest version of JDeveloper 10 and created a very simple project(only have one class with Main()method) for testing purpose.
I configure the Profiler in Project Properties page, setting the class as included instance, however, all those profiling menu items(e.g.: Memory Profile...) are greyed out and I am unable to run memory profiling.
I wonder if the functions are available for the free-downloaed version of JDeveloper, or is there something wrong with my setting?
Your help is highly appreciated.

Make sure you are positioned on the class in the application navigator before going to the "run" menu option.
Also does it work if you don't change anything in the project properties?
Here is what I did - created a new project with a simple hello class. And I didn't had any problems profiling it.
There is no function limitation on the version you downloaded.
Here is the class I tried:
public class Class1
public Class1()
public static void main(String[] args)
Class1 class1 = new Class1();
System.out.println("hello");
}

I can no longer access Safari on my ipad. I get the error:the operation couldn't be completed. Cannot allocate memory. Help please!

I am not able to access Safari on my ipad. I get the error message: The operation couldn't be completed. Cannot allocate memory. Can anyone help please??

Try this first.
Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If that doesn't work, reboot the iPad - or quit all apps and restart.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Quit all apps completely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.

Inactive memory takes all the memory - please help

I have a Macbook Pro - August 2009, upgraded version to 2.66 MHZ, advance display card, Dual core.
I recently upgraded the RAM to 8GB (Kingston) to clear more memory for my massive application use, the thing is it didn't solve anything because the issue I had problems with - Inactive Memory, wasn't resolved.
Inactive memory supposed to hold the memory for the apps you closed in case you'll run them once again, but it NEVER clears the memory, I can see the "blue" color taking all the free mem and the computer slows down! no free mem what so ever.
Now the Inactive mem grows enormously and gets to be more than 4GB, it has the same effect, the memory runs out!
Is there a way to fix it? I'm going crazy with that.. what a terrible design!
iFreeMem doesn't work on the 8GB, I'm at a loss..
Please help!
Thanks,
Eli.

Sounds like you have never done a PRAM reset or a SMC reset. Do both and see if this helps:
_SMC RESET_
• Shut down the computer.
• Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
• On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
• Release all the keys and the power button at the same time.
• Press the power button to turn on the computer.
_PRAM RESET_
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
• Release the keys.

Can't update iphone as not enough memeory on computer. Have tried to move itunes to an external hardrive and I thinm it has moved and clicked on the Itunes folder from the external but still says not enough memory..help

Our computer is REALLY low on memory...we will get a new one at some point but can't at the moment.
Upgraded to the new iphone 4s and bought an external hardrive so I could move my Itunes library to that, so I could update iphone/itunes (isn't enough memeory on PC to do this)
I read that I need to consolidate my itunes first but again when I tried to do this it said not enough computer memory.
Anyway I tried to move the itunes folder over to hardrive and then it looked like it had worked. Clicked on itunes via the external and it opened ituens up..brilliant I thought!Backed my old iphone up and then clicked update...then a m,essage came up saying not enough memeory on comouter to update.
Is this because i need to delete itunes off the computer?
Am worried in case it isn't on the hard drive correctly and will lose everything!

You would be better off to go through and uninstall programs you no longer need or use and move your data over to the external drive, at least temporarily. The iOS update file will be somewhere around 700MB. If your system has less than 20% free disk space, you're pushing the limits even without trying to download something that large and back up your phone so the update can process. If you're running less than 10% disk space you've entered dangerous waters no matter what you're doing.
This really isn't iPhone related and we can't advise you as to what data and applications you can move or delete. You will have to make that determination yourself or get a friend or family member to help.
If you do not have a current backup of your computer system, you need to make one. NOW!

Storing rows returned back in Memory.Urgent Help please

I have a method is thats all information from the Database and I need to hold this data
in a HashMap of some sort of data structure
Lets suppose this result set returns 5 rows.I need to hold all 5 rows in a datastructure.
The variable f_OrderID is the principal and this should return back all values associated with it.
I cant use HashMap as the key:f_OrderID is always the same,
Key f_orderID
Value :f_EffTs,f_ClrAcct f_MsgSeqNum
Please can anyone help me how to store this in memory,
using the same f_OrderID but with different values?
public void getAcctChgDataFromDB(String orderNo,String indicator){
     if((rs == null) ){
                   logger.equals("No rows returned for Order No " + orderNo);
                   throw new AcctChgException("No rows returned for Order No " + orderNo );
              }else
                             while(rs.next()){
                                  f_OrderID = rs.getString("FixOrderID");
                                  f_EffTs    = rs.getString("EffTs");
                                  f_ClrAcct = rs.getString("ClrAcct");
                                  f_MsgSeqNum = rs.getString("FixMsgSeqNum");
         } catch (Exception e) {
               e.printStackTrace();


well i fell
List<Map<String,Object>> or
List<CustomDTOBean>could be a specific data structure which you can look for.
where List would have reference to 5 Objects(Row) and each object could be a Map or a CustomDTO.If we consider map it would be like structure something like
key=TABLE_COLUMN_NAME
value=TABLE_COLUMN_VALUE
