Overview of TN3270 Tracing
TN3270 supports the following types of tracing:
HLLAPI tracing
Traces all the parameters that the HLLAPI application
supplies to the HLLAPI library and all the parameters
that the HLLAPI library returns to the application. For
more information, see “Controlling Tracing of HLLAPI
Applications”.
TN3270 Message tracing
Traces all the data sent from the host to the TN3270
emulation program and from the TN3270 emulation
program to the host. This tracing can also include
TN3270 internal control messages. For more
information, see “Controlling Tracing of the TN3270
Program”.
The relationship between TN3270 components and the boundaries
between components at which tracing can be activated is shown in
Figure 5-1, “Relationship between TN3270 Components and Tracing
Boundaries.”
