Solve the problem of MyEclipse newspaper PermGen space anomaly

Recently developed using Eclipse, the server used was Tomcat, but in the start times the caused By:java.lang.OutOfMemoryError:PermGen space exception.

This error is very common, so configure Tomcat under the Catalina.bat, configuration Eclipse.ini, various methods have been used, not work! It took a long time, in the near collapse of the time to find the following solution, finally solved.

In order not to Detour, I write three methods, I use the third method to solve.

Method/Step

2. 1

   The first method: Modify the Catalina.bat in the Tomcat/bin directory.

4. 2

   Join under "REM-----Execute The requested Command----------------------"

   java_opts= "-server-xms800m-xmx800m-xxnewsize=256m-xx:permsize=256m-xx:maxnewsize=512m-xx:maxpermsize=512m" .

   This approach works when you use Tomcat only, but it doesn't work when you use Eclipse.
6. 3

   The second method: Modify the Eclipse.ini.

8. 4

   Join

   -vm

   D:/jdk6/bin/javaw.exe

   -vmargs

   -dosgi.requiredjavaversion=1.5

   -xms512m

   -xmx1024m

   -xx:permsize=256m

   -xx:maxpermsize=512m

   This method sometimes works, but this time it does not work, the specific reasons I do not know, I guess it may be written above this paragraph with the launch of the Tomcat server in eclipse does not matter, so can not solve the problem of Tomcat error.

10. 5

    Third method: Modify Eclipse's Run configurations.

12. 6

    Click "Run"-"Run Configurations" and click on the "Arguments" tab in the window that opens.

14. 7

    In VM arguments, enter the bottom of the content:

    -xms256m-xmx512m-xx:maxnewsize=256m-xx:maxpermsize=256m

16. 8

    After saving again after restart, no more error.

    It was this method that solved my problem in good condition.
