CP-CP sessions between two VTAM® nodes require both CDRSC and ADJCP definitions at each VTAM to represent the partner CP. The CDRSC definition represents the partner LU, and the ADJCP definition represents the adjacent CP at the connection level. ADJCP definitions can be created dynamically or predefined. When needed, CDRSC definitions are dynamically created for adjacent CPs, regardless of the value coded for DYNLU.
