TRACE Command
BIU
traces basic information units (BIUs) sent to and received from the underlying
access method (such as SNAX/APN or SNAX/XF).
BUFFER
traces records obtained and returned to the local or extended buffer pool.
DFC
traces the finite state machines (FSMs) for the Data Flow Control layer.
LNS
traces the FSMs for the Logical Network Services layer.
PROC
traces data handled by the internal procedures of SNAX/APC.
PS
traces the FSMs for the Presentation Services layer.
QUEUE
traces the enqueuing and dequeuing of internal buffers.
RM
traces the FSMs for the Resource Manager layer.
SPI
traces an object’s hierarchical tree for an SPI command.
TC
traces the FSMs for the Transmission Control layer.
WRAP | NOWRAP
specifies what action is taken when the trace file is full. WRAP specifies that the
trace data wraps around to the beginning of the file and overwrites any data that is
there. NOWRAP specifies that no further entries to the file are made.
Considerations
•
Only one trace can be active per process.
•
Starting a trace for a process collects trace records for all of the subordinate LUs.
