regarding java memory consumption
hello all,
i am developing a multi threaded java application.
the application will run as a service.
the application sends/receives sms. the application stores
the data in the momory as objects and there is a maintainance or
house-keeping phase in the application which runs at every 6 hours.
during the maintainance phase data in the memory is written to
the database. that way the memory(which is a simple arraylist for e.g.)
is cleared.
i was experiencing java.lang.OutOfMemory exception problem.
i specified java -Xmx1000M in the the application bat file
and the problem seems to have disappeared. but after some 15
minutes the application has simply stopped running, its hung.
Questions is? what is the significance of that parameter?
does that mean after the memory of that application exeeds 1000MB the
application will break? also how is this related to the java.exe
parameter in the Task manager. When my application runs, i can see the
mem usage parameter fluctating between 50,000K to 700,000K, does it mean
the application is eating that much memory?
also that values is fluctating, what could be inferred from it?
