NOTE:

When there is insufficient space in the cache, journal data will also be stored

into the journal volume.

Not Use: Journal data will not be stored into the cache.

Blank: The current setting of Use of Cache will remain unchanged.

CAUTION:

This setting does not take effect on master journal groups. However, if the Business

Continuity Manager YKRESYNC REVERSE command is used to change a master journal group
into a restore journal group, this setting will take effect on the journal group. If you set Use,
this setting only takes effect on the journal volumes of RAID-5 or RAID-6 that are in the journal
group. For external volumes, non-RAID-5 journal volumes, and non-RAID-6 journal volumes,
Use works the same as Not Use.

Speed of Line: Allows you to specify the line speed of data transfer. The unit is Mbps (megabits
per second).

You can specify one of the following settings: 256, 100, or 10.

CAUTION:

This setting does not take effect on master journal groups. However, if the Business

Continuity Manager YKRESYNC REVERSE command is used to change a master journal group
into a restore journal group, this setting will take effect on the journal group.

Delta resync Failure: Allows you to specify the processing that will take place when the delta
resync operations are initiated but cannot be performed.

Entire: Whole data in the primary data volume is copied to the secondary data volume
when the delta resync operation cannot be performed. The default is Entire.

None: No processing takes place when the delta resync operation cannot be performed.
Therefore, the secondary data volume is not updated.

CAUTION:

This option cannot be specified in the secondary site.

Timer Type: Allows you to specify the type of clock used for the 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

“Timer Type Option” (page 27)

.

NOTE:

Ensure that the same timer type is specified in both the primary and the secondary sites.

Do not change the Timer Type if At-Time Split function is used when Universal Replicator
for Mainframe and ShadowImage for Mainframe are used in conjunction

You can only specify System if the journal group belongs to an extended consistency
group.

When you use Fujitsu OS, select Local in Timer Type.

Set: Applies the settings in the window to the Journal Operation window (

“Journal Operation

Window” (page 108)

).

Cancel: Cancels the settings and closes the dialog box.
