Continuous Access Asynchronous for Mainframe (Cnt Ac-A)
Stores data and control information for each P-VOL in a sidefile, and performs and manages the
remote copying of volumes independently (asynchronously) of the host I/O processes.
Continuous Access Journal for Mainframe (Cnt Ac-J Z)
Writes updated data and control information to the master journal on the primary site. When the
secondary site makes a read journal request, the updated data and control information are written
from the master journal to the restore journal (on the secondary site). This activity is performed
asynchronously to host I/O processing.
