This topic summarizes the technical changes for this edition.
New and changed information is denoted by carets (
) and (
) at the beginning and end of the new or changed information. Editorial changes
that have no technical significance are not noted.
Revision markers follow these general conventions:
- Only technical changes are marked; style and grammatical changes are not marked.
- If part of an element, such as a paragraph, syntax diagram, list item, task step, or figure is
changed, the entire element is marked with revision markers, even though only part of the element
might have changed.
- If a topic is changed by more than 50%, the entire topic is marked with revision markers (so it
might seem to be a new topic, even though it is not).
Revision markers do not necessarily indicate all the changes made to the information because
deleted text and graphics cannot be marked with revision markers.

Functional and performance improvements:
- In the unload utilities (FABHURG1 and FABHFSU), the number of buffers that are automatically set
for unload data set are increased. For details, see FABHURG1 JCL requirements and FABHFSU JCL requirements.
- If the STEPLIB is APF-authorized, HSSR Engine uses the Media Manager to read VSAM ESDS database
data sets. The use of Media Manager saves the use of CPU time.

| IMS High Performance
Unload for z/OS® 1.2 does not support IMS that are lower than 7.1. Therefore, the names of the IMS libraries that are referred to by the catalog
procedure, provided by the product, are changed to those names of IMS 8.1 and later. |

The following functions are added to the HSSR call:
- The application programming interface for IMS High Performance Unload is extended to support GN and GNP calls with an unqualified SSA
for a dependent segment type of an HD database.
- The application programming interface for IMS High Performance Unload is extended to support EXEC DLI commands.

PQ67004, PQ67296, PQ69199 |
| Complemented explanation of HALDB formats. The description is now as follows:
A HALDB can be unloaded in *HD format by FABHURG1, or in UL format by FABHFSU. Whichever format the
HALDB is in, both the IPR Reload utility of IMS Parallel Reorganization for z/OS 2.1 and IMS High Performance Load for OS/390® 1.1 regard it internally, and therefore refer to it, as having PHD
format. |
PQ66914 |
| Support for the Return Code Edit exit. This APAR provides a new exit for the
HSSR Engine of IMS High Performance Unload.
This exit, called the Return Code Edit exit (FABHRCEX), can be used to modify the return codes
issued by HSSR application programs. |
PQ62843 |
| Added a description of the conditions in which the header record flag
introduced by APAR PQ22654 for HSSR 2.3 causes an incompatibility. If an unloaded data set has been
created by specifying the DECN control statement for a database that contains a compressed segment,
that data set is not compatible with an unloaded data set created by the IMS HD Reorganization Unload utility. |
PQ59762 |
Explanations for three messages:
- The explanation for message FABH0431W is expanded to cover all the conditions in which that
message is issued.
- Explanations of messages FABH0092W and FABH0358W, which had been missing, are added.

PQ59358 |
| Enables IMS High
Performance Unload to run under IMS8.1. |
PQ57581 |
| IMS High Performance
Unload is modified so that Segment Edit/Compression routines are loaded and deleted by the IMS IMODULE service. The APAR also adds message
FABH0853E. |
PQ57815 |
| New control statement, PARTEXTR, for the HSSREXTR DD for the FABHEXTR exit
routine of the FABHURG1 unload utility. The PARTEXTR control statement specifies how many database
records are to be extracted from each HALDB partition. |
PQ55674 |
| IMS High Performance
Unload is modified so that using an uninitialized OSAM database as input causes an error. IMS High Performance Unload is modified so that,
before getting access to a database, it checks the status of each data set in that database. If it
finds an uninitialized data set, it causes an abend U4013. For High Availability Large Database
(HALDB), the first time IMS High Performance
Unload gets access to a partition, it checks the status of the data sets in that partition. If it
finds an uninitialized data set, it causes an abend U4013. |
PQ49420 |
| Added a description that the GOT control statement becomes valid if DBRC is
inactive in the FABHFSU unload utility. |
