Starting WLS Managed Server without entering the credentials

Its simple. Create the boot.properties file under the managed server directory and provide the credentials.
$MW_HOME/user_projects/domains/[domain]/servers/[managed_server]/security

In my case the location is:


/home/ganesh/software/Oracle/MiddlewarePS2/user_projects/domains/soa_domain/servers/soa_server1/security

Also
If you want to specify a custom directory add the following to the startup scripts for the server.
-Dweblogic.system.BootIdentityFile=(path)/boot.properties
