800xA history: Tags not getting synchronized in redundant data collector database
What we have done:
1: Installed History Server and one data collector on first ASCS01 server.
2: Added History Logs in 800xA. Everything get properly syncronized, exept on all clients pointing to ASCS02 there is no 800xA History Trend Available.
3: Installed red data collector on ASCS02 (via SCC) without any error.
If I log into ASCS02 with vtrin there are no tags created in the database, hece on ASCS02 and all clients pointing to ASCS02 there are still no 800xA history trends available.
If I manually try to read the stored history values in the log config of any object it says: "Error: Reading Data OPC_E_INVALIDITEMID(0x0040008) The item definition doesn't conform to the server's syntax"
During installation with SCC under the 800xA History SyncService there was a second Service Group created. So each service group has one service provider which both are status "service"
On the other hand if I look at the 800xA History Admin and configuration manual, I can see at "Figure D.7: Sync Service in Service structure" that there is only one service group but with two service provider in it.
I reconfigured to the latter configuration with only one service group but with no luck for my initial problem.
Even when creating new logs, the tags will only be populated in History server and ASCS01 data collector.
How can i further trace this issue?
Any ideas what went wrong?
Thanks a lot
