Journal standby state

Journal standby state, set by specifying JRNSTATE(*STANDBY) on the Change Journal (CHGJRN) command, will be removed in a future release.

Journal standby state prevents most journal entries from being deposited into a journal and is enabled by option 42 of the IBM i operating system. Journal standby state places restrictions on the use of commitment control, the use of database files that have referential integrity constraints and the use of data links. Also, System-Managed Access-Path Protection (SMAPP) for any access paths built over files journaled to a journal in standby state are flagged as not eligible for SMAPP protection.

The initial implementation of standby state was intended for use on a backup system when there was a desire for low overhead of replicated copies of objects on that system.

This can be achieved via other options, like journal caching, without the restrictions and complications caused by the use of journal standby state.
