Examples of trace output

Use this topic as an example of how to interpret trace output.

Figure 1 shows an example of a trace taken on entry to an MQPUT1 call. The following items have been produced:

  • Queue request parameter list
  • Object descriptor (MQOD)
  • Message descriptor (MQMD)
  • Put message options (MQPMO)
  • The first 256 bytes of message data
Compare this to Figure 2, which illustrates the same control blocks on exit from IBM MQ .
