Configuring the UniInt Failover Startup Parameters with ICU
There are three interface startup parameters that control UniInt failover:
/UFO_ID
,
/UFO_OtherID
, and
/UFO_Interval
. The
UFO
stands for UniInt Failover. The
/UFO_ID
and
/UFO_OtherID
parameters are required for the interface to operate in a failover
configuration, but the
/UFO_Interval
is optional. Each of these parameters is described in
detail in
Configuring UniInt Failover through a Shared File (Phase 2)
section and
Figure 6: The figure above illustrates the ICU failover configuration screen showing the
UniInt failover startup parameters (Phase 2). This copy of the interface defines its
Failover ID as 2 (
/UFO_ID=2)
and the other interfaces Failover ID as 1
(
/UFO_OtherID=1)
. The other failover interface copy must define its Failover ID as 1
(
/UFO_ID=1)
and the other interface Failover ID as 2 (
/UFO_OtherID=2)
in its ICU
failover configuration screen. It also defines the location and name of the
synchronization file as well as the type of failover as COLD.
Creating the Failover State Digital State Set
The UFO_State digital state set is used in conjunction with the failover state digital tag. If
the UFO_State digital state set has not been created yet, it can be using either the Failover
page of the ICU (1.4.1.0 or greater) or the Digital States plug-in in the SMT 3 Utility (3.0.0.7
or greater).
