Mirroring the Historical Database, Report Database, and history message save takes certain time

according to the number of mirrored data items.

If the standby or online SVR goes down during mirroring, mirroring is not performed

successfully.

Perform redundancy switching and initialization of SVR after checking that mirroring is

complete, avoiding on-the-time.

You can see the OIS's station state display screen to check the online-standby state of

redundancy and the mirroring state.
