DADSM dumps

DADSM calls CVAF to perform services on its behalf. If DADSM receives a nonzero return code from CVAF, DADSM module IGG032DB is called to produce a dump.

The dump title line is in the following format. See Figure 1 for a sample title line.

JOBNAME   DADSM  funct  ERROR    TCB=tcbaddr  W/A=workarea

Descriptions of the variables in this format follow:

funct is the failure-related DADSM function.
tcbaddr is the TCB address.
workarea is the DADSM work-area address.

Figure 1. Sample DADSM Dump Title Line

KTMJOB     DADSM  EXTEND  ERROR    TCB=00DC6400  W/A=00DFAB20

Examine the work area pointed to by workarea in the preceding example to locate the eye-catcher CVPL. The CVFCTN field (CVPL +X'06') and the CVSTAT field (CVPL + X'07') in the failure-related CVPL identify the failure-related CVAF function and CVAF status, respectively. For a description of function code values, see Table 1. For a description of the CVSTAT codes, see CVSTAT field codes.
