Our PI Server(3.4.380.36) is 15 seconds delayed compared to our DCS.
I know that adjusting date time is a critical task.
Do I need to stop PI before adjust time?
have you some suggestion to accomplish this task without errors?
Yes it is important to stop the PI server before changing the time, additionally we also recommend stopping the interfaces.
1) If you have any production interfaces on the PI Server, (e.g. pipeschd or pitopi) please stop the interfaces- doing this a minute or two before stopping the PI server.
2) On your interface node, we want to stop the data flow to the PI Server while the time is being changed. If you are using pibufss, you can stop the buffer session to the PI Server or you can shut down your interfaces.
To stop a buffer session, navigate to the pipc\bin directory on the interface node and type: pibufss -bc stop
Note: If you have more than one buffer session, for example, if you are buffering to a PI collective, you are prompted to select which collective member should stop receiving data.
3) On the PI Server node, force a shift on the primary archive.
4) Once the archive shift is completed, stop the PI Server using the pisrvstop.bat file.
5) Change the clock to the right time
6) Start up the server using the pisrvstart.bat file.
7) On your interface nodes, either start the buffer session again or if they had been shut down, restart the interfaces.
To start a buffer session, navigate to the pipc\bin directory on the interface node and type: pibufss -bc start
This has been done by other customers before, some of which had gaps much greater than yours.
I also recommend taking a backup of the PI server before doing this procedure.
Let us know if this helped you!
Tanks a lot Albert.
I really appreciate your help
We're planning this task in the near future
