In-Proc/Out-of-Proc

The OI Server is triggered. Explicitly starting as part of the client process (in-proc) is not currently OI Server supported. Activation using the CLSCTX_ACTIVATE_64_BIT_SERVER flag is also not supported.

Note: The exception to this behavior is OPC UA, which is a service and runs in-proc.

When the OI Server is running out-of-proc, it supports requests from both DDE/SuiteLink and OPC client applications.

If the OI Server is running as a service, the icon on the OI Server node in the SMC is yellow. If the OI Server is not running as a service, the icon is white. For more information, see the Wonderware Operations Integration- Supervisory Server Manager Help.
