History database not updating
History server 2.0
800xa version:22.214.171.124-1 FP4.
there are two history server(Redundant). In history server1 variable current value is not updating but in HS2 it is updating.
when check vetrin in HS1, it is found that Clock is out of sync-Synchronization disabled.
kindly suggest how to resolve the issue.
What is the 800xA History version 2.0, RU1/ RU2/RU3/RU4?
A dedicated 1 Gbps network (Consistency Control Network-CCN Network) connection is required in High Availability onfiguration to connect the redundant history servers for data synchronization.Is this network available?
Time synchronization must be performed between the redundant servers. It is mandatory that High Availability Servers must be synchronized with less than second difference. So it is advisable to use common time source. was the time sysnchronization performed between the servers before installation?
