Journal management concepts

This topic explains how journal management works, why to use it, and how it affects your system.

Journal management enables you to recover the changes to an object that have occurred since the object was last saved. You can also use journal management to provide an audit trail or to help replicate an object. You use a journal to define what objects you want to protect with journal management. The system keeps a record of changes you make to objects that are journaled and of other events that occur on the system.

This topic provides information about how journals work, information about journal entries, and how journals affect system performance.
