Glossary
This glossary defines terms and abbreviations that are used in this book. If you do not find the term you are looking for, refer to the index or to the IBM® Dictionary of Computing.
A
- analysis
- The methodical investigation of a problem, and the separation of the problem into smaller related units for further study.
- abend
- Abnormal end of task; the termination of a task before its completion because of an error condition that cannot be resolved by recovery facilities while the task is executing.
- ADFz
- IBM® Application Delivery Foundation for z/OS® family of products.
- ADFzCC
- IBM Application Delivery Foundation for z/OS Common Components, which provides common functions to ADFz products.
C
- cache
- A buffer storage that contains frequently accessed instructions and data; it is used to reduce access time.
- compiler listing
- A printout produced by compiling a program or creating a file and that optionally includes, for example, a line-by-line source listing, cross-reference list, diagnostic information, and for programs, a description of externally described files.
D
- dump
- To copy the contents of all or part of virtual storage to collect error information.
E
- expert system
- A system that provides for solving problems in a particular application area by drawing inferences from a knowledge base acquired by human expertise.
F
- fault entry
- The information about a fault saved as a member in a history file at the end of real-time analysis. The fault entry might also include a minidump.
H
- history file
- A PDSE data set containing fault entries as individual members.
L
- LANGX side file
- A compiler listing or SYSADATA file, converted to a binary format using the ADFz Common Components IPVLANGX utility, or one of its aliases CAZLANGX, EQALANGX, or IDILANGX.
- listing
- See compiler listing.
- logical history file size
- The number of 4K pages allocated to a PDSE history file at the time of becoming auto-managed or explicitly specified in the fault history file settings.
- loosely coupled dump data set
- A dump data set that is not uniquely linked with a particular fault entry. The fault entry was created as a result of analysis of an already existing dump data set.
M
- minidump
- The storage pages that were referenced during real-time analysis by Fault Analyzer and saved in the history file entry for the fault. A minidump permits later reanalysis of the fault even if no associated MVS dump data set was written.
O
- option
- A parameter that provides control on the operation of Fault Analyzer.
P
- partitioned data set (PDS)
- A data set on direct access storage that is divided into partitions, called members, each of which can contain a program, part of a program, or data.
- partitioned data set extended (PDSE)
- A system-managed data set that contains an indexed directory and members that are similar to the directory and members of partitioned data sets. A PDSE can be used instead of a partitioned data set.
- PDS or PDSE
- A data set that can be either a partitioned data set (PDS) or a partitioned data set extended (PDSE).
R
- real-time analysis
- The analysis undertaken by Fault Analyzer immediately after a program has abended.
- reanalysis
- A second or subsequent analysis.
- Recovery fault recording (RFR)
- A feature of Fault Analyzer which enables abnormal termination of a Fault Analyzer real-time analysis to still create a fault entry of the original application abend.
- RFR dump
- A SDUMP or IEATDUMP data set written during recovery fault recording processing, and associated with an RFR fault entry.
- RFR fault entry
- A history file fault entry written during recovery fault recording processing, and associated with an RFR dump data set.
S
- saved report
- The report that is contained within the fault entry and which can be viewed from the ISPF interface without the need to perform reanalysis.
- side file
- A condensed version of a listing, readable by computers (but not humans).
- system dump
- See dump.
T
- TDUMP
- Synonymous with IEATDUMP. A dump data set type used by Fault Analyzer recovery fault recording processing.
- tightly coupled dump data set
- A dump data set that is uniquely linked with a particular fault entry. It was originally created by Fault Analyzer during real-time processing.
V
- view
- A member of a PDS or PDSE containing a collection of fault history file data set names that are to be displayed simultaneously using the Fault Analyzer ISPF interface.
X
- XDUMP
- Extended minidump data set.
