Chapter 5. Creating DLPAR-aware applications

This chapter provides a brief overview for understanding the new programming paradigm available in a partitioned environment where resources can be dynamically changed/triggered by DLPAR operations. We discuss the following topics:

• Section 5.1, “Dynamic logical partitioning overview” on page 208

• Section 5.2, “The process flow of a DLPAR operation” on page 210

• Section 5.3, “DLPAR-safe and DLPAR-aware applications” on page 214

• Section 5.4, “Integrating a DLPAR operation into the application” on page 217
