Oracle SOA Starts Slow On Linux

Recently I encountered one strange issue while running Oracle SOA server on Oracle Enterprise Linux. Start script of admin server (startWeblogic.sh) halts on this command -

java -client -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8453,server=y,suspend=n -Djava.compiler=NONE  -Xms1024m -Xmx2048m -XX:PermSize=512m -XX:MaxPermSize=786m -Dweblogic.Name=AdminServer ..........................................................................................................
............................................................................................................................................................

After lot of googling I found a solution. This page has details to resolve this issue and I am including a link here to refer it easily in future and for others to find it quickly.

Solution that I used and it worked perfectly is -

1. change $JAVA_HOME/jre/lib/security/java.security
2. Replace securerandom.source with

             securerandom.source=file:/dev/./urandom
