On the weblogic console when trying to start managed Server it’s take too long time to start in my case it’s SOA_SERVER, almost 25 min only to start, which is not correct . to avoid this problem you need to follow the below steps simple but effective :-
Under Java Home ( That Used by Weblogic ) :-
cd /u01/app/fmw/jdk/jre/lib/security
There’s file called Java.Security
Edit this File using any Editor ( vi for example ).
Search for the following line :-
securerandom.source=file:/dev/urandom
And Change it to :-
securerandom.source=file:/dev/./urandom
Or Another way add the below line to startup script in weblogic :-
-Djava.security.egd=file:/dev/./urandom
Hope this will solve your problem.
Thank you
