Interpreting abbreviated-format CICS system trace entries

Abbreviated-format CICS trace entries contain much of the information present in the corresponding extended-format trace entries, and they are often sufficient for debugging purposes. There is a one-to-one correspondence between the trace entry numbers for the abbreviated and extended trace entries, so you can easily identify the trace entry pairs.

Abbreviated trace entries show the CICS TCB-ID of the TCB instead of an MVS TCB address.

Figure 28 gives an example of the abbreviated format for an old-style trace entry.

Figure 28. Example of the abbreviated format for an old-style trace entry
00021 QR    AP 00E1 EIP   ENTRY INQUIRE-TRACEFLAG                             0004,00223810 ....,00007812 ....          =000005=

In this example:

Note:
For some trace entries, an 8-character resource field appears to the right of FIELD B.

Abbreviated old-style trace entries are easy to interpret, as you can readily identify the REQ, FIELD A and FIELD B fields. Note that some such trace entries also include a RESOURCE field.

For ZCP trace entries, FIELD B (which contains the TCTTE address) is printed twice on each line. This allows both sides of the output to be scanned for the terminal entries on an 80-column screen without having to scroll left and right.

Figure 29 gives an example of the abbreviated format for a new-style trace entry.

Figure 29. Example of the abbreviated format for a new-style trace entry
00021 QR    LD 0002 LDLD  EXIT  ACQUIRE_PROGRAM/OK    03B8A370 , 00000001,848659C0,048659A0,410,200,REUSABLE                =000023=

In this example:

Abbreviated-format new-style trace entries are less readily interpreted, because the parameters in the interpretation string are not identified by name. If you are not familiar with the parameters included in the trace entry, you need to look at the corresponding extended-format (or short-format) trace entry to find out what they are. Figure 30 shows the corresponding extended-format trace entry.

LD 0002 shows that this trace entry was made from trace point X'0002' in the loader domain.

The interpretation string provides this information:

The standard information string gives you this information:

The data displayed below the standard information was taken from only one data area. If you look in Lock Manager Domain trace points for details of trace point ID LD 0002, you will see that the data area is the LDLD parameter list.
