Fault history file selection
When a fault is being analyzed in real time by Z Abend Investigator, a history file must be available in which details of the analysis can be recorded.
There are a number of ways in which the name of the history file can be provided to Z Abend Investigator. The following is a list of these in the order of their override significance (each entry in the list overrides all previous entries):
- The product default name, HFZ.HIST.
- The HFZHIST suboption of a DataSets option that is specified in the parmlib config member, HFZCNF00. This information includes either the logical parmlib concatenation or the installation-wide alternate parmlib data set name provided via the HFZOPTLM configuration-options module HFZCNF setting. For details, see Customize Z Abend Investigator by using an HFZOPTLM configuration-options module.
- The HFZHIST suboption of a DataSets option that
is specified in a config member identified via the HFZCNFUM user options module. Note: If a user options module is used, it replaces the default HFZCNF00 parmlib config member. Thus, even if the user options module designated config member did not include an HFZHIST suboption of a DataSets option, any specification of HFZHIST in the default HFZCNF00 parmlib config member would not be recognized.
- The HFZHIST suboption of a DataSets option provided via the HFZOPTS DDname in the abending job step.
- An explicitly coded HFZHIST DD statement in the abending job step.
- The data set name provided by an Analysis Control or End Processing user exit in the ENV data area HFZHIST field.
