Greetings for the day!
I have stuck in a issue, where I am trying to configure OPC Server level failover along with Interface Service failover. The Interface Service failover is some
you said this: "and after few minutes PI OPC Interface service is getting shutdown automatically."
That sounds like the interface might be crashing.
Look at your Windows Application Event log and see if there is an exception at that time.
If so, please contact tech support and let them work through this.
Also, we have released v126.96.36.199 of the OPC DA interface and you should be using that version if possible.
We seem to be missing part of your post...
Yes I missed the complete details.
As mentioned, I am trying to configure OPC Server level failover along with Interface Service failover. The Interface Service failover is working fine, failover of one service second service is taking over have seen some weird behavior.
But important for me is OPC Server Level Failover which is not working. We have 2 FSGateway OPC Server, both active at same time. In OPCInt section primary OPC Server details are provided and in failover section secondary opc server details are provided, delay of 60 sec is provided.
OPCInt version 188.8.131.52, PI Server 2012 with HA
Please suggest what can could be done in this case.
Thanks & Regards,
Thanks for the further information.
I noticed this known issue that we have saying that if an interface ever gets in the BACKUP_NO_DATASource state, it will not recover until you restart the interface service.
I will keeping looking into what would've caused it to go to that state in the first place, though.
To add to Clint's point, the 2.4.x.x versions of opcint were not very stable. OPCInt 2.5 was introduced in order to fix many of the bugs found in 2.4.
I agree that it sounds like the Interface service may be crashing and that you may need to work with TechSupport to get to the bottom of the issue. I imagine you will need to get a crash dump as well.
In the meantime, you can set the service to recover and restart during failure.
-Go to services and find your OPC Interface service
-Right click -> properties
-Make changes on the Recovery tab:
