DFHAPRC

DFHAPRC is the module that provides the gate for the APUS Recovery Manager client. It provides keypoint and restart support for user written log records, which is described elsewhere, and syncpoint support where it serves as a receiver for RMRO calls from the RM domain for prepare, commit, etc. which it converts into appropriate calls to SPP or DBP, as described in DFHSPP and DFHDBP.
