Configure the MES middleware proxy settings

Use the MES middleware proxy settings to configure the default proxy connection information that is used by all client applications running on the computer.

An individual application can override the information with its own connection information.

Any time the Middleware Proxy component is reconfigured while client applications and services are running, restart the client applications and services.

Add a middleware server

• To add a middleware server to the list, select Add.

  A server entry is added to the list.

Update the middleware proxy settings for a middleware server

• Update the following proxy settings for the middleware server:

  Middleware Host

  The fully qualified domain name or machine name of the node on which the middleware service is running.

  If you need to update Middleware Host name from machine name to FQDN (or the reverse), do the following:

  1. Stop all processes including MES applications, application engines, view engines, the AVEVA Galaxy Repository service, the AVEVA OMI Application Manager, and the AVEVA Application Manager.

  2. Update the middleware proxy settings, including the Middleware Host name.

  3. Configure the Middleware Proxy component with the new settings.

  4. Restart any applications and services previously stopped.

  Protocol

  The communication protocol, TCP or HTTP, to use for communications with the MES middleware service. The default is TCP.

  HTTP is typically used when the Middleware Server and client nodes are not located in the same building. TCP is typically used when the Middleware Server and client nodes are located in the same building.

  HTTP Port

  The HTTP port number used by the MES middleware's WCFHostService account for sending asynchronous messages, such as for MSMQ and EventBroker.

  If the Security Mode for HTTP Communication setting in the Middleware Configuration Editor is set to NONE and HTTP is being used rather than TCP for communication between the middleware server and client middleware proxies, this is also the HTTP port number that the MES middleware server and proxies will use.

  The default value is 80, which is the default port number for HTTP. The port number entered here must match the HTTP Port setting in the Middleware Configuration Editor.

  The HTTP port is always used to retrieve the middleware configuration settings regardless of the Protocol setting. You must change this value only when you cannot access port 80 through the firewall.

  HTTPS Port

  The port number for the MES Web API.

  The default value is 443, which is the default for HTTPS.

  The port number entered here must match the common platform HTTPS Port setting of the node on which the MES middleware is running. On the MES middleware node, this setting is on the System Management Service component's Advanced Configuration dialog (see System Management Server and local node common platform HTTPS port settings).

Remove one or more middleware servers from the list

1. Select the server entries.

2. Select Remove.
