Device Types and Subtypes

When you create a trace file, the type and subtype of the device being traced are

recorded in the file. PTrace displays this information in the first trace-file header record.

Table 5-1

lists the device type and subtype numbers assigned to the APLMGR, initiator,

and responder processes.

Trace Record Types

The SELECT keywords for the TRACE command and the PTrace utility are the same.

These keywords relate to the type of process activity you wish to trace and the trace

record types you wish to display. Figure 5-1 on page 5-4 illustrates the type of process

activity each keyword selects for tracing and displaying. If you select the default option,

all types of data are collected or displayed.
