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 i5/OS™ 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.
