Metaspace

A metaspace represents:

• From a deployment perspective, the cluster of ActiveSpaces processes sharing the same metaspace name and discovery URL, making an instance of an ActiveSpaces deployment. The processes in a metaspace provide the resources for hosting spaces.
• From an administrative perspective, a container for a set of spaces. There are two kinds of spaces contained in a metaspace: system spaces, which are defined internally by ActiveSpaces, and user spaces, which are defined by a user.

The metaspace is created when the first process connects to it, and it disappears when the last process disconnects from it.

For detailed information on metaspaces, see the TIBCO ActiveSpaces Developer’s Guide.
