I need a program to keep updating data into DB. but when it's over 2000 cycles. it throws a exception below:java.lang.OutOfMemoryError [JMX RMI Adaptor] <<no stack trace available>>
i was told to increase the Mem size when you run the application. but i don't know how.
thanks for your reply.

you can read this article. url is below. explain how to manage memory.
But In my opinion. this is a design problem, not a memory problem.

Java gc has minor problem if you are not careful while using 'collection'. You have to make sure no references are being held when you expect java gc to work.
