Z Abend Investigator installation and administration
- Preparing to customize Z Abend Investigator
- Customizing the operating environment for Z Abend Investigator
- Using the Z Abend Investigator HFZS subsystem
  Z Abend Investigator uses a subsystem known as HFZS for services that can otherwise not be performed or which might cause incomplete analysis if not started.
- Modifying your ISPF environment
- Customize Z Abend Investigator by using USERMODs
- Customize Z Abend Investigator by using an HFZOPTLM configuration-options module
- Setting up history files
  Z Abend Investigator requires at least one PDS or PDSE data set to be allocated as a fault history file.
  - Determining what size history files to allocate
  - Allocating a PDS or PDSE for a history file
    To allocate one or more history files, edit and submit the sample job HFZSHIST.
  - Allocating secondary space for history files
    For PDSE history files in particular, it is important to allocate the data set with secondary space. Failure to do so might result in out-of-space conditions with subsequent loss of data.
  - Converting history files between PDS and PDSE
    When converting history files from PDS to PDSE data sets, or from PDSE to PDS data sets, set the minimum or maximum fault entries values. Failure to do this might cause unexpected results, including out-of-space conditions.
  - AUTO-managed PDSE history files
    By default, a newly created PDSE history file is AUTO-managed.
  - Changing the size of a PDSE history file
    You can change the allocated size of a PDSE history file.
  - Providing the name of a history file to Z Abend Investigator
  - Setting up views
  - Managing history files across MVS systems without shared DASD
    Views can be used for easy access to fault entries in more than one history file. However, this easy access is only possible when all history files in a view are accessible from the same MVS™ system.
  - Sharing of history files across a sysplex
    Z Abend Investigator uses XCF messaging from HFZS subsystems to efficiently share PDSE history files across all MVS™ images in a sysplex.
  - Managing history file fault entry access
- Setting and changing default options for the site
- Providing compiler listings or Z Abend Investigator side files
- Customizing the CICS environment
- Customizing the DB2 environment
- Customizing the IMS environment
- Customizing the Z Abend Investigator Japanese feature
- Verifying Z Abend Investigator customization
- Managing history files (HFZUTIL utility)
  The HFZUTIL batch utility can be used to perform history file management functions, such as listing and deleting history file fault entries.

- Maintaining Z Abend Investigator
- Disabling Z Abend Investigator
- Customizing Z Abend Investigator by using user exits

Providing the name of a history file to Z Abend Investigator

The current fault history file is determined by an explicitly coded HFZHIST DD statement in the abending job step or the specification of the HFZHIST suboption of the DataSets option. If neither of these are found, the default name is HFZ.HIST.
