Checkpoint Agent Introduction

choose the CPND that oversees the active replica of a particular checkpoint via the invocation of the saCkptActiveReplicaSet() API. In all other cases, the CPD will designate the CPND that oversees the active replica. The CPND that oversees the active replica of a particular checkpoint will control all the operations on that checkpoint and it is not constrained to be present on the same node where the application resides. The CPND that manages the active replica of a particular checkpoint serializes all the requests to that checkpoint from all the applications present at different nodes in the cluster.
