Normal Version (Log Format)

This version of the conversation (with no errors) is provided to help you follow the flow

of information in a normal conversation between two TPs. The version with errors will

contain more detailed information—interpretation of the actual trace.

The Local TP

The conversation is first shown from the point of view of the first speaker, the local TP.

The following screen shows a log of the local TP’s activity in the example conversation.

The log starts and ends with the apc_open/close sequence.

The example conversation starts with a TP-READY verb issued by the local TP.

The local TP uses the TP-READY request to initiate communication with the

SNAX/APC process. The TP-READY request must be the only UOW in the IPC

message; it cannot be concatenated with other UOWs.

The RESOURCE-ID (RID) field in the IPC reply header contains the new resource

ID—in this case it is 38 00 9438. This resource ID is then used by the TP until the

TP releases the resources by issuing a TP-END request.

The parameters of the verb indicate:

•

The local LU name is lus01.

•

The local TP name is progs01a001.
