Goal

A 32-bit OS or JDK has a limitation when trying to allocate memory. A 32-bit OS or JDK will not be able to allocate more than 3 GB on a Linux environment, or 2 GB for Windows environment (not considering the Physical Address Extension (PAE) implementation, which can increase the maximum allocatable memory). When this limit is reached, a migration to a 64-bit architecture is recommended.

This article describes how to migrate a 32-bit JDK domain to 64-bit, which involves a new 64-bit installation of WLS and a 64-bit JDK as well.
