Setting up history files

Z Abend Investigator requires at least one PDS or PDSE data set to be allocated as a fault history file.

Although DUMMY specification of the history file is supported, by using an actual data set you can take advantage of the features provided with the ISPF interface.

  • Never rename a history file unless it is empty. If you do, associated dump data sets will no longer be usable and will not be deleted automatically when the fault entry is deleted.
  • If a history file is deleted without first deleting all fault entries, any associated tightly-coupled dump data sets will be orphaned. Use HFZUTIL DELETE(ALL) to delete all fault entries before renaming or deleting a history file. For details see DELETE control statement.
