Journaling overview

These topics introduce journaling support for integrated file system objects.

Journal management
The main purpose for journal management is to enable you to recover the changes to an object that have occurred since the object was last saved.
Objects you should journal
There are certain questions to consider when deciding whether to journal an integrated file system object.
Journaled integrated file system objects
Some integrated file system object types can be journaled using IBM i journaling support.
Journaled operations
These operations are only journaled when the type of the object or link that the operation is using is a type that can also be journaled.
Special considerations for journal entries
Many journaled integrated file system operations internally use commitment control to form a single transaction from the multiple functions performed during the operations.
Considerations for multiple hard links and journaling
If you have multiple hard links to a journaled integrated file system object, all the links should be saved and restored together so that the linkage is preserved as well as the associated journal information.
