(Optional) This task is only required if you change the default Web API port number to a different one during the AVEVA Production Management installation. By default, the Web Client uses port 9003, so if you're using a different port number, you need to update the number that reflects in the appsettings.json file of the individual Web API microservices.
Before doing this task, ensure that you register the port number you are using with a valid certificate to avoid issues when running the Web Client.
To update the port number
-
Go to the Web Client installation path (...\Program Files\AVEVA\AVEVA Production Management Web Client) and in each of the listed folders, update their individual appsettings.json or AmplaUrl.appsettings.json files.
In the following folders, update the appsettings.json file:
-
Authorization.Api
-
Authorization.Host
-
Configuration.Host
-
Downtime.Host
-
ServiceManager
-
Shiftlog.Host
In the following folders, update the AmplaUrl.appsettings.json file:
-
Configuration.Api
-
Downtime.Api
-
Shiftlog.Api
-
-
Using notepad, search for 9003. You should see sections similar to the following images. Replace the port number with the one you're using and save the file.
