    This IBM® Redbooks® publication helps you to become familiar with the technical changes that were introduced into the Operations areas with IBM z/OS® V2R2.

    This book includes the following chapters:

    - Chapter 1, “SMFLIMxx parmlib member” on page 1 describes how to set up job cancel decisions and region and MEMLIMIT values, based on the job and its environment.

    - Chapter 2, “REGIONX” on page 5 describes the new REGIONX JCL keyword that supports two storage specifications and with which the user can specify values for their below-the-line storage and above-the-line storage needs.

    - Chapter 3, “Two million open data sets” on page 9 describes the ability to have open up to 2,000,000 data sets at a time by address spaces while reducing the allocation time for data sets.

    - Chapter 4, “Dynamic APF SMF Record” on page 11 describes the new SMF record that is used to track dynamic APF changes.

    - Chapter 5, “Initial program load device number and volume” on page 13 describes the new message that is used to identify the initial program load (IPL) device and volume.

    - Chapter 6, “Infoprint enhancements” on page 15 describes the enhancements that were made to Infoprint in z/OS V2R2.

    - Chapter 7, “GRS EQDQ Monitor” on page 19 describes the monitor capture diagnostics for problem determination while minimizing the effect to system performance.

    - Chapter 8, “BCPii System Management Facilities recording” on page 23 describes the record changes to hardware.

    - Chapter 9, “Provisioning based on CPU consumption” on page 25 describes the provisioning that is dynamically based on CPU consumption.

    - Chapter 10, “System REXX enhancements” on page 31 describes the new functions and interfaces of System Rexx.

    This book is one of a series of IBM Redbooks publications that take a modular approach to providing information about the updates that are included with z/OS V2R2. This approach has the following goals:

    - Provide modular content

    - Group the technical changes into a topic

    - Provide a more streamlined way of finding relevant information that is based on the topic

    We hope you find this approach useful and we welcome your feedback.
