Tuning the IBM virtual machine for Java
An application server is a Java based
server and requires a Java virtual
machine (JVM) environment to run and support the enterprise applications
that run on it. As part of configuring your application server, you
can configure the Java SE Runtime
Environment to tune performance and system resource usage. This topic
applies to IBM® virtual machines
for Java.
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.
