Urgent, Please Help - Toplink & ADF Memory Problem

Question

Hi all,
We are using ADF Rich Client, Toplink11g, Oc4j11g. EJB tier is implementing with SessionBeans using Toplink with Database operations. And BackedBeans for serverside.
Users search records and then update them or create record. For examples user enters cardno in first page and in second page access the user informations. And updates info. Then goes back to first page.
Maybe while going back to first page some toplink objects still referenced with another objects.
i am calling a toplink finder method it returns 10-20 rows and showing on a table these records using method iterator. Users select a row and continue with selected row. At the other page the user modify the data and turn back the search page.
I took heap memory dump of server and i saw that 10 objects in memory.In every search and going edit page this count is increasing. In addition i saw cached objects in memory. There is no problem my toplink cache configuration. But i am not using caching with the other object.
I am just calling finder method in a backed bean,without using table and method iterator there is no object in memory.
Is the problem beacuse of adf pgae life cycle?
I am really in trouble.
Thanks to all.

Go to Menu>Tools>File Manager>Options>Memory details, this will give you a run-down of how much phone memory is free and how much is used, then a breakdown of where the memory is being used. Your phone memory is about 140Mb in total (don't confuse this with the 8Gb - that's just "Mass memory" for storage of data like music, video and pictures plus it is possible to install some apps in there. The phone memory is used for processing as well as sotrage, which is why you get these errors if too much is used.
In the breakdown, you'll see the following items:
- Calendar: this should only be a few Kb, perhaps a few hundred Kb if you use the feature often, but not too much
- Contacts: should also be measured in Kb, even if many of your contacts have images
- Messages: should be measured in Kb, if it goes into Mb or worse still Gb then you have Bluetooth of MMS messages hogging space - save the attachments to mass memory and delete the messages.
- Images, videos and soundclips should not be large - perhaps a small number of ringtones, images that you use as backgrounds etc. but the bulk of these media files are best moved to mass memory.
- Documents should be tiny, keep documents in mass memory.
- MIDP (Java) apps and SIS (Symbian) apps could be filling space, you might be able uninstall some of these and reinstall them to mass memory if needs be, but be aware that some apps must be in phone memory and that some of the space taken by SIS apps will be preinstalled stuff that you can't move.
If none of the above can explain the memory full erros and you do seem to have a large amount of Mb free, then it could be a software issue that can be solved by reformatting the phone with the code *#7370# - make sure that you use PC Suite Content Copier to backup important data first, and after the reformat when you restore the backed-up data, don't include settings in the restoration and also leave out any data types that you know you don' use.
