Commands that specify the AT operand are subject to a security check to determine if the command issuer is authorized to direct RACF® TSO commands to the specified node. Because command direction is controlled at a node level, the local node and all target nodes defined to it must have appropriate profiles.

To allow command direction to a specific node, create a profile in the RRSFDATA class to protect a resource called DIRECT.node, where node is the node name.

For information on implementing command direction using the AT operand, see Directing commands using the AT option.
