Setting up outbound and inbound signaling paths
Whether you implement signaling through CTC connections or coupling facility list structures, you need to specify information in the COUPLExx parmlib member. After IPL, you can issue the SETXCF START,PATHOUT or SETXCF START,PATHIN command to specify outbound or inbound paths. To establish signaling through a coupling facility, you also need to define a coupling facility resource management (CFRM) policy.
