Monitoring Jdeveloper Memory and enhancing it for Better Performance

If You are using Jdeveloper and you are facing memory consumption and want to monitor the memory and force the garbage Collector to clean up the memory ,

 you can follow the coming steps 

1- Go to Oracle Home where you setup your Jdeveloper (ex: c:/Oracle)

2- Go to (jdev/bin) you will find file named "jdev.conf"

3- open the file for edit and add this line 

AddVMOption -DMainWindow.MemoryMonitorOn=true

4- restart jdeveloper (close & open ) after restart you will see in lower right corner  the memory consumed and button for enforcing garbage collector to clean the memory 

    

  5- to maximize the memory then under the oracle home (ex: c:/oracle) you will find 

  (ide/bin ) folders and you will find file named ide.conf open the file to edit 

 

6- modify the two values as you see in the screen (if you are using JDK32bit) as following 

AddVMOption  -Xmx1024M

AddVMOption  -Xms1024M

 do not increase the memory over then 1024M rather than jdeveloper will not open ,

if you are using JDK64bit you  Can modify it to

AddVMOption  -Xmx2048M

AddVMOption  -Xms1024M

7- Restart jdeveloper you will see the memory changed in the Lower right Corner
