Inbound communication with XATMI partners

During inbound communication, UTM and UPIC partners that use the XATMI API are also supported. In this case, communication with the UTM partner is always performed via the OSI-TP protocol.

The following applies to communication with XATMI partners:

• Only typed buffers of type X_OCTET are supported.

• An OLTP message-driven bean can use an OltpMessageContext object to determine whether the calling EIS partner is an XATMI partner and - if it is - what paradigm it uses (request/reply or conversational). For details, see Determining sender contexts in the OLTP message-driven bean.

• The length of a (coded) message segment must not exceed 32,000 bytes.

• In the request/reply paradigm, only one message segment may be sent.
