Unable to start Weblogic 10.3

2018-06-29 16:58:34

I am using Windows 8 Pro 64 bit, Java 1.6 64 bit. I am trying to start Weblogic with following memory args (setDomainEnv.cmd):

set USER_MEM_ARGS=-Xmx2048m -XX:PermSize=512m -XX:MaxPermSize=1024m

But i'm getting an error:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

Those mermory args are required to deploy the app, so i can't lower it (physical mermory installed - 8 GB).

Combined with -Xmx512M use -d64 to make sure you're running 64-bit VM. On a 64-bit machine I thought for sure I was running 64-bit virtual machine, but no. After installing 64-bit Java the -d64 option works and -Xmx allows much larger memory sizes.

java -d64 -Xmx512M mypackage.Test

Could not reserve enough space for object heap

I am running weblogic 81. I had min=1024 and max =1024m with 4gb or RAM. 64bit processor and 32 bit java. I tried to increase the min/max value, it did not work. So, I changed the min/max to 512m and 1024m respectively. Thn it started to work.

当我第一次安装SOA环境开发模式时，需要做到这一点：设置JAVA_OPTIONS =％JAVA_OPTIONS％设置DEFAULT_MEM_ARGS = -Xms512m -Xmx768m设置PORT_MEM_ARGS = -Xms768m -Xmx1536m但随着时间的推移，它显示出相同的错误和管道进行以下更改：set JAVA_OPTIONS =％JAVA_OPTIONS％set DEFAULT_MEM_ARGS = -Xms512m -Xmx512m set PORT_MEM_ARGS = -Xms512m -Xmx512m但我仍然不确定为什么发生这种情况。
