Really slow wlst and adminserver start on weblogic

As an alternative to my post here instead of feeding /dev/random with data from /dev/urandom you can switch the weblogic components only.

Modify wlsh.sh
Look for the line

JVM_ARGS="-Dprod.props.file='${WL_HOME}'/.product.properties ${WLST_PROPERTIES} ${JVM_D64} ${UTILS_MEM_ARGS} ${SECURITY_JVM_ARGS} ${CONFIG_JVM_ARGS}"  

and add

-Djava.security.egd=file:///dev/urandom  

to the end of it
or

-Djava.security.egd=file:///dev/./urandom  

Java has a nice crusty bug
https://bugs.java.com/bugdatabase/viewbug.do?bugid=6202721

Which they don’t class as a bug for some reason, it doesn’t do what you ask… yep that’s by design and won’t be fixed!  Use the hack to confuse it, lovely.
