The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Heap Memory VS Systems memory

Asked by appadmin in Application Servers, Computer Memory (RAM), Computer Servers

Tags: OS, JVM, hardware, Application server

Hello Experts,

Can any one tell me whether there is any relationship between the heap size we allocate for the JVM (Application server) and the physical memory (RAM) that our system has.


Let say I have total of 8gb RAM in the server.

now I have 3 jvms (application server instances) running on the box with heap size defined 1024 mb for each JVM.


1)now my question is, does 3gb of memory is taken away from the existing 8gb systems memory.

2)If the above answer is Yes,  what if total 5 gb memory is consumed by systems resources and some of the memory is still left in the 3 gb memory allocated for JVMs,
  so the available memory from 3gb can be used by systems resources (swapped) when they are running out of memory,
   or else when we allocate memory would it br dedicated, like memory cannot be swapped even if some of the resources are running short of it.
