Hi Everyone!

Can anyone tell me all places in PI AF server that I can find a PI DA reference?

Let me explain my problem. I'm building an AF structure and every time I make an update or refresh my tree the elements that use PI Point data Reference bring a %Server% that doesn't exist. In fact, this server has existed in the past, but this machine has been virtualized and assumed another name. I need to find configuration files that reference this server so I can upgrade.

Is it clear?

Already corrected this information on PSE connections
Already corrected this information in Database Configuration
And I have already corrected this information in AFSDK.config

Thanks!

Correct Answer

%Server% is based on a client setting. Therefore, when you use a different client, you would most likely have a different %Server%. In the latest release of AF, we added the ability to designate a default PI Data Archive per AF Server, or per AF Database.

Here you set the default PI Data Archive for your AF Server.

%Server% brings the local machine's Default PI Data Server. So this might be different from 1 client to another.
If you don't need to connect to the virtualized PI node, then you can set your default PI Data server to your new server name.

Hi,

I would like to add few point that would help you to achieve what you want.

Like Jinmo Yi mentioned %Server% will give the default server from the system that you are using.

As you said the AF is retrieving the server name that was configured in past, looks like the old server name is still available in Known server table of the system.

Try clearing the KST from PISDK utility and check the elements where you faced issue.

In PISDK, clean up the KST.

-> Disable the automatic server add option

Hi everybody!

First of all, thanks for all answers. Also, sorry for the delay in answering. I was out of the office and unable to access PI Square. Unfortunatel all of these tips presented except for "Disable the automatic server add option" I already tried.
So I will disable the automatic server add option and force the correct server name.

Bests!

Olá Paulo:
I also might suggest you clean up the 'ServerAliases' listing in the Registry Editor.
To do this open Registry Editor. Navigate to \HKEY_LOCAL_MACHINE\SOFTWARE\PISystem\PI-SDK\1.0\ServerAliases. It is possible if you have decommissioned pi servers they were once listed here, but are now under a five digit number listing. Depending on how many are there you can click on them and view the 'handle' value in the [Data] column. Here you will likely find a listing for an old server.
Before proceeding right click on the 'ServerAliases' node and Export them to a backup file that can be re-imported if needed.
With a backup in place - simply delete the server alias (five digit listing) of the now missing server.
