For an overview of all Natural add-on products and the new
product versions available, see Overview of New Natural Add-On Product
Versions.
This section describes the new features provided with Natural Development Server Version 9.1.2.
Note:
The sections indicated for more information are contained in
the Natural Development Server documentation in the
Documentation section of Software AG's Empower web site at
https://empower.softwareag.com/, unless
otherwise noted.
The following two new session parameters have been added to the Natural Development Server for z/OS (Batch).
- SECURITY_CACHING
enables a client directory that stores user information for subsequent actions
- SECURITY_TIMEOUT
manages the life time of clients
These parameters are available via two additional buttons in the HTML Monitor Client that list or cancel clients and their respective sessions.
The documentation of a Predict Program object, with the object's implementation pointer completely filled (i.e. Natural member name, library name, user system file number, and user system file database id), is deleted when the Natural member is deleted in an NDV environment.
By default, the switch "Delete documentation with
deletion of Natural member" is initialized with
"Y", i.e. deleting the existing documentation.
If you wish to keep the documentation set this new switch to
"N".
Start a Predict session and go into the defaults settings, Protection.
The enhancement provided with Natural for DB2 Version 8.4.3 is described in the following section.
Natural for Db2 now supports shared memory objects above the bar to be used as storage media for file servers.
This avoids I/O against VSAM files and switches between SRB and TCB modes when using the Natural for DB2 file server and running zIIP-enabled.
For more information, see
File Server –
Shared Memory Object (Database Management
Systems Interfaces documentation) and the new
SMFSRV
subparameter of the DB2 profile parameter
(NTDB2 macro).
You can now specify the number of rows to be fetched by Db2 in one FETCH operation by using
the new MF
subparameter of the DB2 parameter or NTDB2 macro
(see also Changed/Enhanced Profile Parameters). This helps to improve performance and
enhance zIIP usage in a zIIP-enabled Natural session.
Natural for Db2 for zIIP (NDZ) is a new Natural add-on product that allows you to run Db2 workloads on IBM System z Integrated Information Processors (zIIP).
For more information, see Natural for Db2 for zIIP.
The BS2000 file maintenance facility now also provides the
option to display and set the file attribute #BACK-VERS for the
number of file versions to be saved in a backup archive. For details, refer to
the section BS2000 Files in the User's
Guide of the Natural ISPF documentation on
Software AG's documentation web site at
https://documentation.softwareag.com/.
For information on changes, enhancements and new features available with NaturalONE, see the Release Notes in the NaturalONE documentation in the Documentation section of Software AG's Empower web site at https://empower.softwareag.com/.

For detailed information on these features, refer to the indicated chapters in the Utilities documentation.
- Service Directory Maintenance: Cursor Now Placed at Inserted Lines
The
Iinsert line command of the Service Directory Maintenance now places the cursor at the position where new items can be entered for a selected node.For more information, see Line Commands in the section Commands for Service Directory Maintenance
Natural zIIP Enabler products have been renamed as follows:
| Old Name | New Name |
|---|---|
| Natural zIIP Enabler for Batch | Natural Batch for zIIP |
| Natural zIIP Enabler for CICS | Natural for CICS for zIIP |
| Natural zIIP Enabler for Com-plete | Natural for Com-plete for zIIP |
Natural for IMS for zIIP (product code NAZNI) is now available to support IBM's System z Integrated Information Processors (zIIPs) in an IMS TM environment on z/OS if Natural IMS TM Interface Version 8.3.5 is installed. For more information, see the Natural for zIIP documentation.
Note that Natural for IMS for zIIP requires a license file.
When running zIIP-enabled under z/OS, the
MT profile
parameter applies separately to both TCB and SRB (zIIP) processing
modes. If MT=0 is set in SRB mode, Natural uses the existing z/OS
TCB time limit to avoid endless loops because there is no z/OS CPU time limit
(for example, the JCL TIME parameter) for SRBs.
