MIMIX uses journaling to perform replication and to support newer analysis functionality.
Journaling and object auditing - Journaling and object auditing are techniques that allow object activity to be logged to a journal. Journaling logs activity for selected objects of specific object types to a user journal. Object auditing logs activity for all objects to the security audit journal (QAUDJRN, the system journal), including those defined to a user journal. MIMIX relies on these techniques and the entries placed in the journal receivers for replicating logged activity.
Journal - An IBM i system object that identifies the objects being journaled and the journal receivers associated with the journal. The system journal is a specialized journal on the system which MIMIX uses.
Journal receiver - An IBM i system object that is associated with a journal and contains the log of all activity for objects defined to the journal.
Journal entry - A record added to a journal receiver that identifies an event that occurred on a journaled object. MIMIX uses file and record level journal entries to recreate the object on a designated system.
Remote journaling - A function of IBM i that allows you to establish journals and journal receivers on one system and associate them with specific journals and journal receivers on another system. Once the association is established, the operating system can use the pair of journals to replicate journal entries in one direction, from the local journal to the remote journal on the other system. MIMIX uses remote journaling to transfer replicated data from the source system to the target system and to distributed information among systems.
