WAS7 stopNode.sh -stopservers

If  the stopNode.sh -stopservers ask you for a valid user and password, it worth to understand that authentication information has changed since version 7.X

In Version 6.1 and earlier, user ID and password information was obtained by this command from the profile_root/properties/soap.client.props file. In this version of the product, the same information is obtained from theprofile_root/properties/ipc.client.props file

./stopNode.sh  -stopservers
