Setting up history files

Fault Analyzer 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.

Attention:

With one exception, do not 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.
The exception to this rule is when following the procedure outlined in Changing the size of a PDSE history file.
If a history file is deleted without first deleting all fault entries, any associated tightly-coupled dump data sets will be orphaned. Use IDIUTIL DELETE(ALL) to delete all fault entries before renaming or deleting a history file. For details see DELETE control statement.
