DSC Citadel5: Can I copy all files of my Historical DatabasePath to use them somewhere else?

[tomker]

Hi,
I am using LV7.x with Citadel5 on some connected NT4 & w2k - PC´s and a Server.
I have to save all 2000 Tags (updated per second) for backup reasons and I want
to view them on other hosts.
Is it possible to copy files of my Historical DatabasePath to use them on another host?
I tried this already, but the traces do not appear (wrong URL ?).
It is senseless to use the archive function for 200 tags.
thanks
tom

Hi,
meanwhile I tried to help myself, an I found:

There should be two new vi´s called: Make Network Database Path.vi and Split Network Database Path.vi
I can´t find these VI´s in LV 7.1 with DSC5

Tom,
There were quite a few changes (especially with VI names) between LVDSC 6.1 and 7. They are covered in the LVDSC release notes for v7.0 here. One of them was:
"The Make Network Path VI and Split Network Database Path VI are gone from the palette, since database paths are no longer used."

Have you tried using Get Trace List.vi (renamed from "Get Historical Tag List" in DSC v6.1) to get a list of the available traces/trends in the database that you copied? It will return the correct URL syntax for the tags ... something like \\computername\processname\tagname where computername will be the name of the computer running the Tag Engine containing the tagname and processname probably will be LabVIEW.

To backup your db to another PC/Server/NAS you should use the Archive Traces.vi that is located in the Historical Data Palette. If you want to see traces from db files that were copied to another PC you need to go to MAX/Historical Data/Citadel 5 Universe and right clilck on "My Computer". Choose Create/Attach Database... to register the db in Citadel 5.

I hope this helps,
