If you are not familiar with wsadmin.sh (Linux) / wsadmin.bat (Windows), check out our Getting Started article.
By default, wsadmin will use SOAP. You can use the -conntype option to spectify the type of connection you would like to make, like this:
wsadmin.sh -conntype NONE wsadmin.sh -conntype SOAP wsadmin.sh -conntype RMI wsadmin.sh -conntype IPC wsadmin.sh -conntype JSR160RMI
-conntype NONE is used to run in local mode, which means that wsadmin does not connect to any server processes. In this way, wsadmin can be used even if a server is not running. This is useful if you want to, say, install software on a server that is not running.
