Tuning HotSpot Java virtual machines (Solaris & HP-UX)

The architecture of the Sun-developed, HP-ported HotSpot Java virtual machine (JVM) has evolved differently than the IBM-developed software development kit (SDK.) Its internal structure, for young or old generation and permanent regions, arises to primarily support generational garbage collection, as well as other garbage collection modes as necessary.

Before you begin

About this task

Tuning the Sun HotSpot JVM is an iterative process where the JVM configuration is developed, data gathered, primarily from verbosegc data, and then analyzed, and any configuration revisions applied on the next cycle. Perform one or more of the following steps if you need to tune your Sun HotSpot JVM.

Procedure

What to do next

Gather and analyze data to evaluate the configuration, typically using verbosegc. Continue to gather and analyze data as you make tuning changes until you are satisfied with how the JVM is performing.
