IOF Release 7E

Topics

Introduction

IOF Release 7E will soon be available for beta testing. 7E is a full maintenance release of IOF that incorporates all available IOF corrective maintenance and adds support for the OS/390 Workload Manager.

Release 7E is year 2000 compliant, and has no known problems running with the system clock set before or after the turn of the century. Release 7D is also year 2000 compliant, and has many hours of successful developer and customer testing. Release 7E is built from the proven 7D code with all available maintenance applied. Should any Y2K problems be discovered, they will receive top priority for resolution.

The current release 7D of IOF will continue to be supported. You can continue to run release 7D if you are not experiencing problems, and if you do not need the support for running Workload Manager in goal mode.

Workload Manager Support

Release 7E provides support for Workload Manager goal mode. When the a system is running in goal mode, several IOF panels automatically change to display different fields and accept new commands. For example, the performance group field on the System Monitor Panel changes to service class when the system is running in goal mode. The new service class field can be modified by over-typing.

Several panels change when operating in goal mode. New workload manager fields are displayed and new commands can be entered. The table below shows many of the new fields and commands by panel.

Access Control

IOF access control has been enhanced to control access to new workload manager fields and commands. The new Start Job command, which causes an input job under workload manager control to start execution immediately, requires level 3 update authority. Changing service class or setting quiesce on or off requires level 4 update authority. These default levels can be changed by modifying the B21ACESS option.

Except for 7D corrective maintenance, no other access control changes were made to the new release. The 7D version of the B23ALLOW option and other access control options can be used without modification for 7E. This should make conversion from 7D to 7E quick and easy.

Corrective Maintenance

All 7D corrective maintenance has been applied to release 7E. Installing the new IOF release is a good way to install all available IOF maintenance.

Beta Test Sites

The beta test program for IOF 7E has been completed. We wish to thank all the beta sites for installing and testing release 7E, and for forwarding their comments and suggestions back to us.
