==Janus/TN3270 Debugger Build 65==
==RKTools Version 7.7==
<div class="mw-collapsible-content">
<div class="mw-collapsible-content">
On September 1 2016, Build 65 of the Janus/TN3270 Debugger Client was released.
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>
 
===Web interface===
<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>
<p>
RKWeb is mobile-ready and provides a task-based UI for SOUL application development. Using RKWeb utilities, you can:</p>
<ul>
<li>Build applications</li>
<li>Manage SOUL code, passwords, groups, and SSL Certificates</li>
<li>Monitor performance</li>
</ul>
<p>
RKWeb also includes a journal scanner, command interface, and readers for [[SirTune]] reports and [[SirFact]] dumps.</p>
 
===Ease of installation===
<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>
 
===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>
 
===Integration of Dictionary/204===
<p>
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.</p>


When Build 65 is used with Model 204 version 7.7, you can force Debugger Clients to have at least a minimum build number in order to invoke a debugging session with your Online. The new Model&nbsp;204 system parameter <var>MINDEBCL</var> sets such a minimum.
===SQL Server utilities===
<p>
As of RKTools 7.7, the RKWeb interface makes available the [[SQL catalog#Using the SQL catalog|SQL Server]] Table Specification facility (TSF) and the catalog reporting utility (CCACATREPT).</p>


If you set <var>MINDEBCL</var> to a positive value, use a version of the Debugger Client whose build number is less than <var>MINDEBCL</var>, and invoke a debugging session, the debugging session is rejected.
===Downloading instructions===
<p>
To download RKTools version 7.7:</p>
<ol>
<li>Navigate to the [https://m204.rocketsoftware.com/maint/ullist?nickname=ROCKET SOUL files for Rocket Software] page.</li>

==DROWN security threat to Janus SSL ports==
==Janus/TN3270 Debugger Build 66 and 67==
<div class="mw-collapsible-content">
<div class="mw-collapsible-content">
[[Janus Network Security]] customers should be aware of a security threat known as the "DROWN attack" (https://drownattack.com/). The DROWN threat exploits a security vulnerability of network SSL ports that use SSL V2.
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&nbsp;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 <code>log.txt</code>; 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 <var class="book">[[Media:JdebugrNew.pdf|User's Guide]]</var> for details (Builds 66 and 67 in the "Release Notes" chapter).

The main features in these releases of Model 204 and RKTools are summarized on this page and described in greater detail in the [[Release notes for Model 204 version 7.6]] and the [[Release notes for RKTools V7.5]].


===Model 204 version 7.6===
<table>
Model 204 version 7.6 has added new features and functionality to provide continuous growth and expansion of your Model&nbsp;204 investment.
<tr class="head"><th>Category</th>
<th>Feature</th></tr>


====New performance features====
<tr>
<table class="thJustBold">
<td>Performance</td>
<tr><th>64-bit storage</th>
<td>
<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.)
<ul>
<p>
<li>Continued expansion of 64-bit addressability. See [[#Elimination of BTB buffers|Elimination of BTB buffers]]. </li>
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>


<tr><th nowrap>M204 HPO <br>(IBM z/OS systems only)</th>
<li>Greater zIIP processor availability: M204 HPO and Fast/Unload HPO. See [[#zIIP exploitation|zIIP exploitation]]. </li>
<td>Release 7.6 enhances zIIP (IBM System z Integrated Information Processor) support by making most of the Model 204 code zIIP tolerant. <var class="product">M204 HPO</var> (High Performance Option) offloads to zIIP almost all MP-capable code (Model&nbsp;204 code that can run on an MP subtask). 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 zIIP offloading is freely and implicitly available to all customers, the HPO zIIP support requires an additional license. For more information, [[Contacting Rocket Software Technical Support|contact Rocket Software]]. </p></td></tr>

<tr><th>Fast/Unload HPO</th>
<li>Essential removal of application limits on the [[#Increase in request limit for number of images, screens, and menus|number of images, screens, and menus]].</li>
<td>Fast/Unload invoked by the <var class="product">Fast/Unload Soul Interface</var> can take advantage of zIIP processing at sites that purchase licenses for both the add-on feature Fast/Unload HPO (High Performance Option) and the <var class="product">M204 HPO</var> add-on. </td></tr>


<tr><th nowrap>High Performance FICON (zHPF)</th>
<li>Support for large data sets (as many as 16 million tracks) for the Model 204 Checkpoint facility [[Checkpoints: Storing before-images of changed pages#Creating the CHKPOINT.2FCHKPNT .28and CHKPNTS.29 data set|CHKPOINT or CHKPNTS data sets]]. See [[System and media recovery#ROLL BACK processing.2C Pass 2|ROLL BACK processing, Pass 2]].</li>
<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>
