Setting up history files
Fault Analyzer requires at least one PDS or PDSE data set to be allocated as a fault history file.
Changing the size of a PDSE history file
You can change the allocated size of a PDSE history file.

Fault Analyzer installation and administration
- Migrating from an earlier version of Fault Analyzer
- Preparing to customize Fault Analyzer
- Customizing the operating environment for Fault Analyzer
- Using the Fault Analyzer IDIS subsystem
  Fault Analyzer uses a subsystem known as IDIS for services that can otherwise not be performed or which might cause incomplete analysis if not started.
- Modifying your ISPF environment
- Customize Fault Analyzer by using USERMODs
- Customize Fault Analyzer by using an IDIOPTLM configuration-options module
- Setting up history files
  Fault Analyzer 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 IDISHIST.
  - 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
  - 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 Fault Analyzer
  - 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
    Fault Analyzer uses XCF messaging from IDIS subsystems to efficiently share PDSE history files across all MVS™ images in a sysplex.

- Customizing the DB2 environment
- Customizing the IMS environment

- Managing history files (IDIUTIL utility)
  The IDIUTIL batch utility can be used to perform history file management functions, such as listing and deleting history file fault entries.

Changing the size of a PDSE history file

You can change the allocated size of a PDSE history file.

Procedure

Stop the IDIS subsystem.
Rename the original history file to a unique name to ensure that the file is not used as a history file by others. For example, append ".OLD" to the history file name.
Allocate a new, larger history file with secondary extents using a unique name that is different from the original history file (for example, by appending ".NEW").
Copy the complete contents of the ".OLD" history file to the ".NEW" history file using IEBCOPY or ISPF option 3.3.
Using File > Change Fault History File Settings from the action bar, set the Logical History File Size (Pages) value to 0. For additional information about this setting, see Change fault history file settings.
Rename the ".NEW" history file to the original history file name.
Start the IDIS subsystem.
Delete the ".OLD" history file using ISPF option 3.2 or similar.
