Eclipse崩溃,错误提示: MyEclipse has detected that less than 5% of the 64MB of Perm Gen (Non-heap memory) space remains. It is strongly recommended that you exit and restart MyEclipse with new virtual machine memory paramters to increase this memory. Failure to do so can result in data loss. The recommended Eclipse memory parameters are: eclipse.exe -vmargs -Xms128M -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M
-vmargs -Xms128M -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M -vmargs 说明后面是VM的参数,所以后面的其实都是JVM的参数了 -Xms128m JVM初始分配的堆内存 -Xmx512m JVM最大允许分配的堆内存,按需分配 -XX:PermSize=64M JVM初始分配的非堆内存 -XX:MaxPermSize=128M JVM最大允许分配的非堆内存,按需分配
