Database synchronization of correction values

[riccardo.crociani]

Hello,

we use WinCC OA 3.11 with a 2x2 configuration and Oracle database on PSS and SSS.

We have configured the "2x2 Redundancy Configuration Online Values" by the proper wizard to syncrhronize the online values.

Now we have developed a custom driver that sends some data directly into the database as correction values (by the config entry "histDataBits").

How can we synchronize those correction values from PSS database to the SSS database ?
Is there any way to do it automatically ?

Thanks for your help.

The correction values should be synchronized as part of the historical data, which is only automatically triggered for the time period of connection loss between PSS and SSS.

But it is possible to manually synchronize a freely definable time range.

Hi,

thanks for the reply.

Ok I can use the Historical Values synchronization tool available in the SysMgm (in the 2x2 Redundancy tab) and trigger a custom synchronization by a script with an appropriate time range, is it correct ?

Canno't I force the tool to synchronize only the offline values ?


Thanks.

Yes, it should be possible to write a script to execute the historical value synchronization with a specified time range.

There is no option to only synchronize the correction values.
