If you are not sure what a profile is, refer to this article.
The manageprofiles.sh (Linux) or manageprofiles.bat (Windows) command with the -listProfiles option can be used to list the profiles on the system. In this example, there are two profiles, AppSrv01 and AppSrv02.
~]# ${WAS_INSTALL_ROOT}/bin/manageprofiles.sh -listProfiles
[AppSrv01, AppSrv02]
By default, profiles reside at ${WAS_INSTALL_ROOT}/profiles, so you can just as easily list the contents of the ${WAS_INSTALL_ROOT}/profiles directory.
~]# ls ${WAS_INSTALL_ROOT}/profiles
AppSrv01 AppSrv02
