When starting a Weblogic Managed Server from the shell, you will be requested to enter username/password. You can however bypass it by using the boot.properties file. This text file should contain the username/password to start/stop an instance of WebLogic Server. Here are the steps to execute this recipe:
1. Create boot.properties in $DOMAIN_HOME/servers/[server_name]/security with content like:
username=[superuser with admin role like weblogic]
password=[password of user]
2. Repeat this step for the Weblogic Admin Server and all Managed Server.
