One of the most important decisions in planning for MIMIX is determining which IFS objects you need to replicate. Most likely, you want to limit the IFS objects you replicate to mission-critical objects and the directories that contain them. You also need to determine whether the IFS objects you need to replicate are better suited for replication by system journal (object) or user journal (database) replication processes.
When you choose the shipped default configuration options, MIMIX uses data group IFS entries to determine whether to process transactions for objects in the integrated file system (IFS), and what replication process is used. IFS entries can be configured so that the identified objects can be replicated from journal entries recorded in the system journal (default) or in a user journal (optional).
You can optionally configure a data group to use a journal-centric configuration for IFS objects. When a data group specifies *ALL or *IFS object types for journal-centric configuration, data group IFS entries are not needed to identify what to include in replication. MIMIX keeps track of which IFS objects are journaled to the user journal associated with the data group and transactions for those IFS objects are replicated via the user journal.

Important! User journal replication of IFS objects (also called advanced journaling), is well suited to the dynamic environments of IFS objects. While user journal replication has significant advantages, you must decide whether it is appropriate for your environment. For more information, see Planning for journaled IFS objects, data areas, and data queues. Objects configured for user journal replication may have create, restore, delete, move, and rename operations. Differences in implementation details are described in Processing variations for common operations. If you already have data group IFS entries configured for system journal replication, they can be converted to user journal replication. The most efficient way to convert IFS entries for an enabled data group from system journal replication to user journal replication is using the Convert Data Group IFS Entries (CVTDGIFSE) command.
