Hi Experts,

I just install SOLMAN 7.1 SPS 11.

I want to configure System preparation but the system is keep loading until no end when click on "EDIT".

Please advise if you have any idea.

I have ran SGEN. also the also memory looks normal.

Able to access to http://localhost:50000 without performance issue.

Default Java memory are

-XX:MaxNewSize=600M 

-XX:NewSize=600M 

-XX:MaxPermSize=512M 

-XX:PermSize=512M
