Embedded cache

WebSphere eXtreme Scale grids can run within existing processes as embedded eXtreme Scale servers or you can manage them as external processes.

Embedded grids are useful when you are running in an application server, such as WAS. You can start eXtreme Scale servers that are not embedded by using command line scripts and run in a Java™ process.

When to use

Use embedded grids when there is plenty of memory free in the client process for grid data and potential failover data.

For more information, see Enable the client invalidation mechanism.
