sql developer:

Unable to create an instance of the Java Virtual Machine

Located at path:

修改该文件,设置“AddVMOption -Xmx”参数,如下
AddVMOption -Xmx256M


eclipse:

Failed to create the Java Virtual Machine

打开eclipse目录下的eclipse.ini文件

--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m

将256改成128
