S+ Operation 2.06 Long Term trend cannot be fully loaded
We have update 3 servers from SPO 2.02 to SPO 2.06
1 Server : OK
1 Server (red) : OK with issue
1 signal Trending with long term data : OK
More than 10 signal with long term data : Loss, Trend window totally blank
1 Server : the worst issue.
Event 1 signal, it can retrieve only for several long term data, cannot retrieve longer data as LifeTimeHist setting (180 days)
For additional information, we have follow procedure as per manual but the result as above mentioned.
is there anyone who has same issue? and how to solve this issue?
Please check whether the balancing is done earlier before upgrade or not. If not, then this is due to the mismatch in data between 2 historian servers which results in data loss. Follow the balancing recommendation as per the user manual (sql command "balance Me" from web portal - case sensitive). Else, if it is already upgraded and you want to use the first history server data as reference and sync the other history server that is also possible..
Which ever is convenient/possible for you please take a call based on the project requirement.
Refer to user manual for more information.
