– Entire: Whole data in primary data volume will be copied to secondary
data volume when delta resync operation cannot be performed. The
default is Entire.
– None: No processing will take place when delta resync operation
cannot be performed. Therefore, the secondary data volume will not be
updated.
Caution: This option cannot be specified in the secondary site.
• Timer Type: Allows you to specify the type of clock used for consistency
time.
– System: The system clock of the mainframe host is used.
– Local: The system clock is not used.
– None: The system clock of the mainframe host is used. The difference
between System and None is explained in section
Timer Type Option.
Notes:
– Ensure that the same timer type is specified in both the primary and the
secondary sites.
– If At-Time Split function is used when URz and SIz are used in
conjunction, the Timer Type cannot be changed.
– You can only specify None if the journal group belongs to an extended
consistency group.
• Set: Applies the settings in the window to the Journal Operation window
(
