History file properties
To display attributes and statistics for the currently selected fault history file, first select
from the action bar.- Allocated Extents
- The total number of extents allocated for the history file. Shown only if the user has data set READ access to the history file.
- Allocated Space
- The total allocated data set space in original allocation units. For PDSE history files the equivalent number of pages is also shown. Shown only if the user has data set READ access to the history file.
- Average Minidump Size
- The average size of all minidumps saved in this history file or view is indicated as the number of minidump pages.
- Current Fault Entries
- The current number of fault entries in the history file.
- Data Set Utilization
- Pages used as percentage of pages allocated. Only available for PDSE history files. Shown only if the user has data set READ access to the history file.
- Fault ID Prefix
- The fault ID prefix assigned to all fault entries in a history file. This prefix can be changed with the IDIUTIL batch utility using the SETFAULTPREFIX control statement (see Managing history files (IDIUTIL utility)). Alternatively, this setting can be changed using the Fault Analyzer ISPF interface (see Change fault history file settings).
- History File Access
- Read or Update.
- History File Name
- The name of a history file explicitly displayed, or a history file that is contained in a view.
- History File Type
- This name is indicated as one of the following:
- PDSE (Library)
- PDSE (Library type 1)
- PDSE (Library type 2)
- PDS (Partitioned Data Set)
- History File Utilization
- Used space as a percentage of history file size. (Only shown for PDSE history files.) Shown only if the user has data set READ access to the history file.
- Logical History File Size
- If available, the current logical history file size. Shown only if the user has data set READ access to the history file.
- Minimum Fault Entries
- The number of fault entries that must exist in the PDSE history file before it is maintained
automatically, regardless of how many data set extents have been allocated to achieve this. Once the
history file is maintained automatically, then the number of fault entries is limited only by the
currently available data set space. No more data set extents are generally allocated and no
out-of-space conditions are expected.
The minimum number of fault entries can be changed with the IDIUTIL batch utility SetMinFaultEntries control statement (see Managing history files (IDIUTIL utility)). Alternatively, this setting can be changed using the Fault Analyzer ISPF interface (see Change fault history file settings).
- Maximum Fault Entries
- The maximum number of fault entries to be maintained in this history file, before automatic
deletion of the oldest entries.
Additional data set extents are allocated as needed to achieve this number of fault entries. An out-of-space condition occurs if there is no space available in the data set (that is, the maximum number of data set extents has been reached or the volume is full) prior to the history file containing nnn fault entries.
If "n/a", then no maximum fault entries has been assigned to the history file.
For PDS history files, the maximum number of fault entries can be changed with the IDIUTIL batch utility SetMaxFaultEntries control statement, and for PDSE history files, the IDIUTIL batch utility SetMinFaultEntries control statement (see Managing history files (IDIUTIL utility)). Alternatively, this setting can be changed using the Fault Analyzer ISPF interface (see Change fault history file settings).
- Maximum Minidump Size
- The largest minidump saved in this history file or view is indicated as the number of minidump pages.
- Minimum Minidump Size
- The smallest minidump saved in this history file or view is indicated as the number of minidump pages.
- Number of Entries With Associated MVS™ Dump
- The number of entries in the history file or view with an associated MVS™ dump data set. The percentage of the total entries is also shown.
- Number of Entries With Minidump
- The number of entries in the history file or view that include a saved minidump. The percentage of the total entries is also shown.
- Number of History Files
- If a view is displayed, the number of history files that are contained in the view. Information about individual history files follows.
- Primary Space
- The primary data set space allocation in original allocation units. For PDSE history files the equivalent number of pages is also shown. Shown only if the user has data set READ access to the history file.
- Secondary Space
- The secondary data set space allocation in original allocation units. For PDSE history files the equivalent number of pages is also shown. Shown only if the user has data set READ access to the history file.
- Total Number of Entries
- The total number of entries in the view.
- Used Space
- For a PDSE history file, this is the total number of pages used. For a PDS history file, this is the total number of original allocation units used. Shown only if the user has data set READ access to the history file.
- View Name
- If a view is displayed, the name of the view.
