Trace-Record Formats

To display all provider records related to associate or attach operations, use the

following PTrace command:

FROM TRACE01;SELECT PROV;FILTER PROV CONNECT

To display messages for all ASN1 subtypes except the ASN1 Decode subtype, use the

following PTrace command:

FROM TRACE01;SELECT ASN1;FILTER NOASN1DEC

Trace-Record Formats

A trace file contains a trace file header record followed by one or more trace records.

Type and subtype describe the format of the trace record and indicate what was

happening when the trace information was taken. The subdevice name identifies the

association to which the trace data applies.

The remainder of this section describes the contents of the file header record and of each

type of trace record listed in Table 5-2

on page 5-7.

Note. The formatted trace files created for you by the SCF TRACE command may not appear

exactly as documented in this manual. Additionally, the formats of individual trace records are

subject to change with product IPMs or with new software releases. Records (or fields within

records) may be added or deleted as necessary.

Trace records provide a mix of internal and user information and reflect your network

configuration and the type of applications you are running.

Trace records are used for product development and maintenance as well as for tracking down

protocol problems in user applications.

PTrace might not be able to display all data (for example, a complete DSM command buffer) if

the data is longer than the trace record size specified by the SCF TRACE command. The trace

record size is shown in the trace-file header record display. Guidelines for the trace record size

(RECSIZE option) are provided in the command description for TRACE PROCESS

page 3-116.
