    An often underutilized and misunderstood attribute of IBM i5/OS® is the journal standby mode. This mode is available through the optional feature, Option 42, of the i5/OS operating system. Shops that use a high availability product often enable this mode beneath their replicated files on the target system.

    While journal standby mode is a useful feature in the proper context, there are some possible subtle side effects. This Technote helps you think through those considerations and avoid, or at least mitigate, most of the potential gotchas. We also explain how important it can be to combine use of the INACCPTH(*ELIGIBLE) system-managed access-path protection (SMAPP) setting with any use of journal standby mode.
