When a program first opens a connection, the connection is stopped—that is, it does not deliver inbound messages. To begin the flow of inbound messages, the program must explicitly call tibemsConnection_Start. (Outbound messages flow even before calling tibemsConnection_Start.)The EMS C and COBOL APIs do not support the JMS methods createConnectionConsumer and createDurableConnectionConsumer (which are optional in the JMS specification).However, when a program uses a connection only to receive messages, the client lacks that opportunity to detect problems. Instead, programs can handle such errors asynchronously by defining an exception listener callback (see tibemsExceptionCallback on page 231).
