Jdeveloper启动报错-jvm.dll

启动Jdeveloper时报错，提示：

“unable to create an instance of the java virtual machine located

at path:C:\Oracle\Middleware\jdk160_24\jre\bin\client\jvm.dll

报错信息如下图所示：



解决办法：

打开“C:\Oracle\Middleware\jdeveloper\jdev\bin”下的jdev.conf文件，将-XX:MaxPermSize=400M变更为-XX:MaxPermSize=256M，如下所示

#
# MaxPermSize is required to run JDeveloper with Sun Microsystems virtual
# machine (-client and -server).  The default value is 64M, which isn't
# enough to run JDeveloper successfully.  With the default value, JDeveloper
# will end up running out of memory at some point in time.  For technical
# details, see: http://java.sun.com/docs/hotspot/gc5.0/gc_tuning_5.html #
AddVMOption  -XX:MaxPermSize=256M

变更后重新启动即可。
