Command resource names (sometimes called entity names) enable you to logically group your own commands and name each group for the purpose of controlling access to the commands. After you have defined the groups of commands and given each group a resource name, your RACF® administrator must define the command groups to RACF. You must also define who is allowed to issue commands from each group and have the RACF administrator supply this information to RACF. After the administrator has provided the required information to RACF, you can use the command resource name on the CMDAUTH macro to perform authorization checking.
