Unwired WorkSpace online help contains details about configuring MBOs to enable DCN to refresh cached MBO data.
MBOs belong to a single cache group, although MBOs in the same project are not necessarily in the same cache group. The cache group policy determines the data refresh behavior of all MBOs within the group. DCN can be used as the sole mechanism of refreshing cached data in Unwired Server by specifying the DCN cache refresh policy.
