Abstract

The Dynamic Logical Partitioning features of IBM eServers provides the ability to logically attach/detach system resources (e.g., CPUs and memory) to/from a logical partitions operating system without rebooting. This invention provides mechanism for notifying Java applications of DLPAR events, which will permit them to dynamically change their runtime behavior when these events occur. This invention also provides a mechanism for a Java application to dynamically increase/decrease the size of the Java Virtual Machine's heap in response to DLPAR events.
