How do I delete multiple records from a file from the EMA proxy cache admin console ?
Can you please clarify what you are trying to achieve? EMA is an API and does not cache any data - all the requested data is immediately delivered to the application through callback.
If your intention is to unsubscribe from an already open instrument, then use the handle for that item for invoking the unsubscribe call.
long handle = consumer.registerClient( EmaFactory.createReqMsg().serviceName(srvStr).name("IBM.N").payload(view), appClient, 0 ); . . . // stop the subscription consumer.unregister(handle);
