What’s New in Release 18.02

ISPW is a modern, end-to-end Agile source code management, release automation, and deployment automation tool that enables mainframe application developers at all skill levels to fulfill business requirements, optimize code quality, and improve developer productivity through mainframe DevOps.

The ISPW Release Notes include all information--such as new features, system requirements, technical notes, and known issues--for ISPW.

Release 18.02 includes the following enhancements:
January 3, 2019
ISPW Eclipse

  Eclipse Project support has been added.

-- This adds the new Active Assignment View where you can do most of your work.

-- Leverages Eclipse functionalities which work off projects.

  Fallback API now can specify a specific Assignment, Release, or Task.

  New API to Transfer Task to another Assignment or Release.

  Several existing views have become default views. For an existing workspace, reset the perspective to automatically see the new default views.

October 1, 2018
zAdviser Support

Enhanced functionality to collect ISPW usage data and provide records to Enterprise Common Components to upload for use and analysis by zAdviser. zAdviser can then measure quality, velocity, and efficiency of Mainframe development. Refer to the Enterprise Common Components Advanced Configuration Guide for Release 17.02 for detailed instructions on how to enable the creation of zAdviser records.

ISPW Eclipse

  Ability to copy values to the clipboard from Tasks View and Error Logs View.

  Ability to select a selective deploy environment when using the fast path operations (Promote/Deploy/Fallback/Regress).

June 28, 2018
ISPW

New APIs for your DevOps tool chain.

  Assignment and Release Operations: Cancel, Close.

  Set Operations: Restart, Terminate and Approve, Deny, Reset.

ISPW Eclipse

  Performance Improvements.

  Improved the Workflow--Fast Path and Advanced.

-- Made a fast path to quickly Generate, Promote, Deploy, Regress, and Fallback.

-- Advanced options for scheduling and modify processing. You can now schedule Regress and Fallback processing.

  Topaz CLI for ISPW now supports downloading of specific Set, Assignment, or Release containers as well as downloading of changes (instead of complete download) on subsequent runs of the downloading process.

January 4, 2018
Simplified Installation Process

Release 18 features an improved installation experience. This will make it easier and faster to perform both new installations and upgrades.

  The new ISPW Guided Configuration dialog lets you follow the installation steps on a screen with the JCL generated for you. This provides a clearer view of the steps and where you are with the JCL built from your input.

  ISPW has been converted to use the Compuware Common PARMLIB for specifying parameters.

  The ISPW Installation and Configuration Guide has been significantly revised to provide a faster, simpler installation experience.

  An upgraded SMP/E implementation now uses ++MOD for smaller, easier-to-install quarterly maintenance.

  The Natural and QMF options have been brought into the normal installation.


Software and Hardware Requirements

The Software and Hardware Requirements are now located in the ISPW Installation and Configuration Guide .


Technical Notes
Configuring Memory Settings for ISPW Eclipse

Java OutOfMemory errors may occur when editing a large file or displaying a large JES report. These errors can often be avoided by increasing the maximum size of the JVM memory heap. The initialization files in Topaz Workbench or Eclipse (topaz.ini or eclipse.ini) include an Xmx parameter (default 512m or 1024m) used to specify the maximum heap size. The optimum value for this parameter varies depending on the OS used, memory fragmentation, and other factors.

On 32-bit Windows, the theoretical heap size is limited to 2GB due to how Windows allocates memory, but this is reduced by many factors. Generally, the stated maximum is 1536m, while a commonly stated max range is 1200m to 1500m. The optimal setting for a particular installation--with no OutOfMemory errors or noticeable garbage collection pauses--can only be determined by experimenting with different values. Compuware recommends increasing the Xmx value to 1200m as a starting point and increasing or decreasing the value in small increments, such as 512m, until an optimum value is found. However, even with a setting of 1536m, large JES output can easily exceed that value. The only practical solution in such situations is to install the products on a 64-bit OS.

On 64-bit Windows operating systems, heap size is limited by your Windows virtual memory specification, minus a small amount of memory used by the OS and other processes. Specifying 4GB or more for the Xmx parameter can be practical depending on the Windows virtual memory size.
