Increasing memory of JDeveloper IDE

Problem
JDeveloper 11.1.1.3 by default comes with 768M of Max memory. When you have lot of files or objects in memory(I noticed this during XSLT of a large structure) JDeveloper runs out of memory and cannot open the file.

Solution

1. Go to C:\JDeveloperStudio11113\jdeveloper\ide\bin
2. Open ide.conf
3. And increase the memory to 1024 : AddVMOption  -Xmx1024M
4. Restart the Jdeveloper and this should not cause any poblem.
