Planning to use IBM eXtremeMemory
By configuring eXtremeMemory, you can store objects in
native memory instead of on the Java™ heap. When you configure eXtremeMemory, you can either allow the
default amount of memory to be used, or you can calculate the amount
of memory that you want to dedicate to eXtremeMemory.
Security overview WebSphere eXtreme Scale can
secure data access, including allowing for integration with external
