AP domain trace points: old style

Trace entries in the range AP 0000 to AP 00C2 are user trace entries, the numeric part of the point ID is defined in the application making the trace call. Trace entries in the range AP 00C3 to AP FFFF are AP domain system trace entries, not all the values in this range are used. Where descriptions are given of the specific contents of the REQ field, FIELD A, FIELD B, and the RESOURCE field, byte positions are numbered from left to right, starting at 0.

Format of REQ, FIELD A, FIELD B, and RESOURCE fields

These fields can contain the following information:
  • The request code
  • The entry type
  • Data relevant to the entry
  • the name of the resource associated with the request
Field Contents
REQ
Byte 0 and
byte 1,
bits 0–3
 For system entries, byte 0 and byte 1 (bits 0–3) typically contain the request code relating to the type of CICS® management involved. For user entries, these bits are not used.
   
REQ
Byte 1,
bits 4–7
 These bits indicate the type of entry, as follows:
X'2' User entry
X'3' LIFO system entry
X'4' System entry
X'5' LIFO response/return
X'D' Trace on/off entry
   
FIELD A
Bytes 0–3		 Data relevant to this entry
   
FIELD B
Bytes 0–3		 Data relevant to this entry
   
RESOURCE
Bytes 0–7		 When provided, the RESOURCE field typically contains the name of the resource associated with the request being traced. Details are provided in the following topics.

Contents of the trace entry resource field

This table displays the contents of the trace entry resource field, including the trace ID, the program name, the request types, and the resource description.
