有时候,Jdeveloper的运行环境很慢,需要手动配置运行环境的内存大小,
但是更改了大小以后,偶尔会报 Unable to create an instance of the Java Virtual Machine的问题,导致jdeveloper启动不了,下面说一下如何更改jdeveloper的运行内存和解决该问题
- 更改内存大小:在jdeveloper的安装目录下,找到jdev\bin\jdev.conf
,打开该文件,更改AddVMOption -XX:MaxPermSize=512M - 设置 Xmx 和 Xms:打开文件 [jdev_home]\ide\bin\ide.conf
修改参数 AddVMOption –Xmx1024M AddVMOption –Xms512M
这时候,在启动jdeveloper的时候,有可能会报Unable to create an instance of the Java Virtual Machine,这时候,就需要在jdev.conf文件中,AddVMOption -XX:MaxPermSize=512M
的后面,加上
AddVMOption -Xmx512M
AddVMOption -Xms256M
