Announcing
IOF
Release 8B

 IOF Release 8B contributes significant new function to the product.   8B adds to the new direction and emphasis provided by the very successful release 8A.  Release 8A usability enhancements have been improved and streamlined.  

Topics

Overview

IOF Release 8B has been enhanced to provide additional  interfaces to  recently announced z/OS features.  The restructuring that was implemented in release 8A has been improved and streamlined to make it easier to install and tailor the product.  8B preserves the original look, feel, and functionality of  IOF while providing significant new function for the product.

Release 8A  supports all versions of z/OS through V1R8.   Additional IOF releases with even more enhancements will follow very soon.

 

Health Checker

The IBM Health Checker is a generalized facility for dynamically analyzing the health and status of both IBM system components and software systems from other vendors. The Health Checker allows the customer to prioritize exception events and provides status alerts for the more serious exceptions.

The new IOF 8B CHK command displays the results from the Health Checker analysis.  Specific system checks can also be dynamically activated or deactivated from this panel.  System check exception priorities can be set and checks can be assigned to specific check categories . IOF is the complete tool for displaying check results and managing the Health Checker.

Line commands are available to activate, deactivate or refresh specific system checks.  Each check status can be displayed or modified.  Health reports produced by each system check can be browsed or edited directly from this menu as well. 

The specific set of checks displayed on this menu are defined locally.   Most checks are supplied by IBM as part of various components of the operating system. Checks can also be provided by other software vendors for their products.

Depending on your screen size, you may have to right-scroll multiple times to display all of the available information. As an alternative to scrolling, you may instead use the D line command for a check that will display all information in three separate panels, shown below.

WLM Scheduling Environments

Scheduling Environments are part of Workload Manager's Resource Affinity Scheduling facility. A Scheduling Environment is named list of abstract resource names along with the required state (On or Off) of each resource in the list. A resource can be in one of three states; On/Off as mentioned previously, and Reset (the initial or unset state). A scheduling environment is considered "available" on a particular system when each of the named resources in the list is in the required state on that system.

The S option of the WLM command causes the IOF Scheduling Environment Display to be displayed.  This panel lists all defined environments.

WLM Resources

The new R option of the WLM command displays all defined WLM resources without regard for scheduling environments to which they may be assigned.   Resource state can be changed or reset from this panel.

Usability Enhancements

The 8B dynamic option menu has been improved to more accurately display options that each user has the authority to use.  User experience installing release 8A was instrumental in the design and implementation of  these changes.

The CMDS help has been expanded significantly to document dozens of commands that were previously documented only in the User's Guide or in the Installation Guide.  This feature makes it easier for users to find and learn how to use some of the powerful but obscure IOF commands.

Release 8B  Availability

IOF Release 8B was officially made available on October 25, 2006.. 

It is anticipated that Release 8C with additional new features will available in the first quarter of 2007.

Beta Version Availability

A beta version of 8B will be available in August 2006.  The beta version will run in parallel with your production release 8A or release 7 version of IOF.  It uses the same SVC/ESR as the production IOF. 

The beta program for release 8B has been closed.
