CIMON Historian Database Redundancy |
CIMON Historian database supports redundancy to provide high stability and reliability.
Supported network redundancy model
Redundancy model - Single DB Redundancy Architecture |
UltimateAccess Web v1.0 and later
Single DB Redundancy structure without replicating the Historian DB.
Historian DB - Can be installed on Window OS (Win 10,11 / Windows Server), Linux OS
When switching happens, Historian DB on the secondary server logs the data.
When switching happens, the standby server becomes active after 1 to 5 seconds based on the network condition.
Redundancy model - Dual Redundancy Architecture |
Dual type redundancy model structure.
Stream Replication between Historian DBs
When switching server happens, Historian DB on the secondary server logs the data.
When switching Historian DB server happens, the substitute (secondary) Historian DB performs as an active server.
In dual redundancy structure, UltimateAccess Web does not provide a solution for Historian DB redundancy. The user has to find external HDA solution company to build the Historian DB redundancy.
Not supported network redundancy structure
Redundancy model - Redundancy between internal databases |
Historian databases between the PCs where UltimateAccess Web runtime is running are not supported.
