From the error, the application uses legacy MD interface
(MarketDataSubscriber) which doesn’t support RSSL connection type.MarketDataSubscriber supports SSLED connection type which
uses TCP port 8101 (default port).\Connections\Connection_SSLED\PortNumber = 8101
\Connections\Connection_SSLED\UserName = "<username>"
\Connections\Connection_SSLED\ServerList = "<hostname>"
\Connections\Connection_SSLED\connectionType = "SSLED"Therefore, the legacy application (MarketDataSubscriber)
can’t switch to RSSL connection type. If the connectionType used by
MarketDataSubscriber is RSSL, RFA will generate this log.Illegal attempt to create MarketDataSubscriber using RSSL connection type
Connection name: Connection_SSLED
Connection type: RSSLTo support RSSL connection type, the application must use OMM interface (OMMConsumer). Please refer to the StarterConsumer
example in RFA package which shows how to use OMM interface to create a
consumer application. Otherwise, you can refer to these online tutorials.0
