Here are my abstracts for the conference:
Session B11: DB2 Data Sharing Performance for Beginners
This presentation provides an introductory-level view of how to look at the DB2 Data Sharing performance numbersfrom both a z/OS / RMF and a DB2h perspective.
Performance topics include: XCF, Coupling Facility, Data Sharing Structures, The application’s perspective, and Structure Duplexing.
Performance topics don’t include: Other forms of Data Sharing eg VSAM RLS, and overly detailed descriptions.
Session P22: Memory Matters in 2008
For z/OS LPARs memory management has changed radically over the years – from both the operating system perspective and that of applications. And the pendulum has swung back and forth between focusing on Real Memory and on Virtual Memory.
This presentation discusses managing both Real and Virtual Memory – from the perspectives of both the operating system and the exploiting products. The products include DB2, DFSORT, CICS, IMS, MQ and Websphere. One topic of particular importance to installations upgrading z/OS is the Release 8 Real Storage Manager rewrite.
Session P23: Much Ado About CPU
zSeries and System z9 processors have in recent years introduced a number of capabilities of real value to mainframe customers. These capabilities have, however, required changes in the way we think about CPU management.
This presentation describes these capabilities and how to evolve your CPU management to take them into account. It is based on the author’s experience of evolving his reporting to support these changes.
