In asynchronous delivery mode, the journal entries are placed in the source journal first (A in Figure 38) and then applied to the source database (B). An independent job sends the journal entries from a buffer (C) to the target system journal receiver (D) at some time after control is returned to the source applications that generated the journal entries.

Because the journal entries on the target system may lag behind the source system’s database, in the event of a source system failure, entries may become trapped on the source system.

With asynchronous delivery, the most recent copy of the data is on the source system. Performance critical applications frequently use asynchronous delivery.

Default values used in configuring MIMIX for remote journaling use asynchronous delivery.
