<div class="mw-collapsible-content">
Rocket Software is pleased to announce the commercial availability of two new releases: Model 204 version 7.6 and RKTools Version 7.5.
RKTools 7.7 is commercially available in July, 2017.
<p>
The main features in this release are summarized below and described in greater detail in the [[Release notes for RKTools V7.7]].</p>


===Model 204 version 7.6===
===Web interface===
Model 204 version 7.6 has added new features and functionality to provide continuous growth and expansion of your Model&nbsp;204 investment.
<p>
 
New in version 7.7 is [[RKWeb]], an easy-to-use web interface for managing the entire Model 204 environment. The RKWeb tools framework provides a highly productive web interface to common Model&nbsp;204 functionality.</p>
====New performance features====
<table class="thJustBold">
<tr><th>64-bit storage</th>
<td>This release continues the 64-bit enablement of the Model 204 infrastructure begun in version 7.4. By moving Model 204 “above the bar,” scalability, performance, and growth are limited only by the system architecture and memory. As of version 7.6, STBL, VTBL, and several other tables can now be placed into swappable or non-swappable server storage area above the bar. (This is in addition to FTBL, GTBL, NTBL, and QTBL, moved above the bar in previous releases.)
<p>
<p>
Note that using above-the-bar storage could bring new challenges to customers who have written assembly language functions for use within Model 204. Rocket Software provides a set of service offerings to help accommodate your upgrade and conversion needs. Contact Rocket Software for details. </p></td></tr>
RKWeb is mobile-ready and provides a task-based UI for SOUL application development. Using RKWeb utilities, you can:</p>
 
<tr><th nowrap>zIIP offload (IBM z/OS systems only)</th>
<td>Release 7.6 enhances zIIP (IBM System z Integrated Information Processor) support by making most of the Model 204 code zIIP tolerant. Almost all MP-capable code (Model 204 code that can run on an MP subtask) is offloaded to zIIP. Code that cannot be executed on zIIP uses the MP subtask or a maintask.
 
<p class="note"><b>Note:</b> While a limited version of this capability is available to all customers, the fully improved zIIP support requires an additional license. For more information, [[Contacting Rocket Software Technical Support|contact Rocket Software]]. </p></td></tr>
 
<tr><th>Fast/Unload</th>
<td>The add-on feature Fast/Unload HPO (High Performance Option), new in Model 204 version 7.6, activates zIIP processing for the <var class="product">Fast/Unload Soul Interface</var> (requires license for Model&nbsp;204 zIIP processing).
 
<tr><th>High Performance FICON (zHPF)</th>
<td>Model 204 version 7.6 supports IBM's High Performance FICON (zHPF) feature (for z/OS systems 2.01 and higher), which allows faster I/O by limiting the number of interactions between the channel and the device.</td></tr>
</table>
 
====SOUL enhancements====
Additional enhancements have been made to SOUL (formerly User Language), including:
<ul>
<ul>
<li><var>Json</var> class, for exchanging data with other platforms using the JSON format. </li>
<li>Build applications</li>
 
<li>Manage SOUL code, passwords, groups, and SSL Certificates</li>
<li><var>Private</var> keyword for <var>Class</var> declarations. </li>
<li>Monitor performance</li>
 
<li><var>Friend</var> declarations for <var>Class</var> blocks. </li>
 
<li>New "SSL" string methods. </li>
</ul>
</ul>
<p>
<p>
The preceding list is a subset of the new features and functionality within Model 204. Review the M204wiki [[Release notes for Model 204 version 7.6]] page as well as the [[M204wiki main page]] to see the latest enhancements and improvements that Model&nbsp;204 has to offer. </p>
RKWeb also includes a journal scanner, command interface, and readers for [[SirTune]] reports and [[SirFact]] dumps.</p>


===RKTools version 7.5===
===Ease of installation===
The first version of [[RKTools]] is now available. Formerly known as UL/SPF, these utilities now provide advanced features to enhance programmer productivity, encourage the use of Soul OO programming constructs, assist in debugging and problem analysis, and help increase Model&nbsp;204 availability. The product [[Release notes for RKTools V7.5|release notes]] introduce its new features.
<p>
As of version 7.7, all code for all Rocket-provided, SOUL-based products and utilities resides in the M204PROC file. This includes all the [[Dictionary/204 overview|Dictionary/204]] components (SUBSYSMGMT, FILEMGMT, etc.), all the [[SQL Server overview|SQL Server]] support code, and all code for the former UL/SPF products such as [[SirPro]], [[SirMon]], and [[SirScan]].</p>


<p class="note"><b>Note:</b> RKTools 7.5 requires Model 204 7.5 or higher.</p>
===Security===
<p>
In version 7.7, JANSSL ([[Janus Network Security]]) is integrated with the other components in the RKWeb interface. Its operation is the same as before, and it is available without RKWeb from a Janus port as before. </p>
<p>  
V7.7 JANSSL also includes support for SHA2 SSL Certificates, including SHA384.</p>


====SirScan, SirMon, and SirLib====
===Integration of Dictionary/204===
Highlights of this release include the following features:
<p>
<ul>

This page contains recent and forthcoming additions of note to Model 204 documentation.

RKTools Version 7.7

RKTools 7.7 is commercially available in July, 2017.

The main features in this release are summarized below and described in greater detail in the Release notes for RKTools V7.7.

Web interface

New in version 7.7 is RKWeb, an easy-to-use web interface for managing the entire Model 204 environment. The RKWeb tools framework provides a highly productive web interface to common Model 204 functionality.

RKWeb is mobile-ready and provides a task-based UI for SOUL application development. Using RKWeb utilities, you can:

  • Build applications
  • Manage SOUL code, passwords, groups, and SSL Certificates
  • Monitor performance

RKWeb also includes a journal scanner, command interface, and readers for SirTune reports and SirFact dumps.

Ease of installation

As of version 7.7, all code for all Rocket-provided, SOUL-based products and utilities resides in the M204PROC file. This includes all the Dictionary/204 components (SUBSYSMGMT, FILEMGMT, etc.), all the SQL Server support code, and all code for the former UL/SPF products such as SirPro, SirMon, and SirScan.

Security

In version 7.7, JANSSL (Janus Network Security) is integrated with the other components in the RKWeb interface. Its operation is the same as before, and it is available without RKWeb from a Janus port as before.

V7.7 JANSSL also includes support for SHA2 SSL Certificates, including SHA384.

Integration of Dictionary/204

As of version 7.7, Dictionary/204 is integrated into RKTools, and it is accessible through both the RKTools and RKWeb interfaces, as well as from the Model 204 command line as before.

SQL Server utilities

As of RKTools 7.7, the RKWeb interface makes available the SQL Server Table Specification facility (TSF) and the catalog reporting utility (CCACATREPT).

Downloading instructions

To download RKTools version 7.7:

  1. Navigate to the SOUL files for Rocket Software page.
  2. Provide security credentials when prompted.
  3. Locate the RKTools V7.7 link and click its Download procfile link.


Janus/TN3270 Debugger Build 66 and 67

On July 5, 2017, Build 67 of the Janus/TN3270 Debugger Client was released. On April 3, 2017, Build 66 was released.

When Build 66 is used with Model 204 version 7.7, you can configure automatic creation of a new Client log file on a daily basis to prevent excessive growth of the log. You can also turn logging off.

Build 67 lets you specify how many days worth of previous Client logs to retain. The new daily log is always named log.txt; the names of previous daily logs include their creation dates.

Build 67 also lets you relocate and optionally rename the installed default locations of the Debugger Client Help file, its PDF-file representation, or both.

See the Debugger User's Guide for details (Builds 66 and 67 in the "Release Notes" chapter).
