By configuring eXtremeMemory, you can
store objects in native memory instead of on the Java™ heap. Configuring eXtremeMemory enables
the IBM® eXtremeIO transport
mechanism.
About this task
For more information about eXtremeMemory and its benefits
versus the Java heap to store
your data grid objects, see
IBM eXtremeMemory. When
you are using eXtremeMemory, eXtremeIO is used for communication between
container servers. Objects are serialized into bytes on the container
server. To enable eXtremeMemory, you set the required server properties
on all of the container servers in the data grid and restart the servers.
eXtremeMemory
is not used on catalog servers. If you have a catalog server and a
container server that are collocated, the container servers use eXtremeMemory,
but the catalog server does not.
What to do next
You can also set properties to configure eXtremeIO. For more
information, see
Configuring IBM eXtremeIO (XIO).
