Each server instance,
including the Administration Server, has a default persistent store that
requires no configuration. The default store is a file-based store that
maintains its data in a group of files in a server instance's
data\store\default
directory. In fact, a directory for
the default store is automatically created if one does not already
exist. This default store is available to subsystems that do not require
explicit selection of a particular store and function best by using the
system's default storage mechanism.
However, you can change this store's default directory location and its Synchronous Write Policy.
For more information about these fields, refer to Configuration Options.
