Fault Tolerance
7 EMS: The event format file for event
210010 enumerated the 3rd variable of
the event in a table. It should have been
the second variable that was
enumerated. There is no third varbind
sent in the trap.
This was resolved by adjusting the file to
show the correct information in the
appropriate place and format.
8 Event Manager & Alarm Manager: The
user received an error obtaining the
current time from VNM when logging in
as a non-Admin user.
This was resolved by creating a new
required model type that contains non
secure read only attributes, such as
current time. The new model type does
not have a security string set so it is
accessible by anyone.
Corrected Issues: Fault Tolerance
Item Problem Resolution
1 Old alarms appeared to “regenerate” on
the primary SpectroSERVER when a
database synchronization was done to
the fault tolerant secondary
SpectroSERVER. It appeared that the
secondary SpectroSERVER was
regenerating these alarms when it came
back up, and was logging the events to
the Archive Manager running on the
primary SpectroSERVER system. This
was being caused by the 3 - 4 minute lag
of the switch-over from primary to
secondary on the restart of the
secondary after a db sync.
This was resolved by having the system
read the primary SpectroSERVER's
VNM_UP_TIME attribute following a
failure. It will now switch over
immediately if this is greater than or
equal to three minutes.
2 A user model information error message
was being received by the
SpectroGRAPH during a failover from the
primary to the secondary
SpectroSERVER. This was caused when
an attribute watch registration failed
because the secondary SpectroSERVER
had not yet detected that the primary
SpectroSERVER was down.
This was resolved by having the
secondary SpectroSERVER attempt to
poll the primary SpectroSERVER when a
client request fails. If it cannot contact
the primary it will switch to primary
mode and re-dispatch the request to its
local landscape.
