In general terms, a replication path is a series of processes that, together, represent the critical path on which data to be replicated moves from its origin to its destination.
MIMIX uses two replication paths to accommodate differences in how replication occurs for databases and objects. These paths operate with configurable levels of cooperation or can operate independently.
-
The user journal replication path captures changes to critical files and objects configured for replication through the user journal using the IBM i remote journaling function. In previous versions, MIMIX DB2 Replicator provided this function.
-
The system journal replication path handles replication of critical system objects (such as user profiles or spooled files), integrated file system (IFS) objects, and document library object (DLOs) using the IBM i system journal. In previous versions MIMIX Object Replicator provided this function.
Configuration choices determine the degree of cooperative processing used between the system journal and user journal replication paths when replicating files, IFS objects, data areas, and data queues.
Within each replication path, MIMIX uses a series of processes. This chapter describes the replication paths and the processes used in each.
