Right.<br>
When your region is connected to a physical grid, your region is *just*
a 3D space server, nothing else.<br>
All assets belong to the asset server, all inventories belong to the
inventory server, all users belong to the user server.<br>

so, it doesn't seem that my region server (the opensim instance
I might run as part of someone's grid) is doing much of
anything since any change in prim or agent attribute must be
conveyed back to the grid's asset server.

<pre wrap="">By "assets" I mean the data itself, the blobs/text/etc.
The region prims/primitems storage holds only references to that data.
Look inside OpenSim.db. There is no "data" there, only meta data and
references to the data (by UUID) stored on the asset server.

<pre wrap="">When you say the prims and primitems are not assets, I am confused.
My understanding was that all items are assets, identified by their unique
UUIDs. If I follow the point about the asset server, the asset servers
stores all asset UUID references by region, but that the specific asset
attributes (i.e., position of an object, or its texture) are stored by UUID
in the region's DB?

<pre wrap="">The asset server holds the assets for the entire collection of regions

the asset corresponding to that object is stored on the asset server.
The region caches some assets in memory. For example, in that creation
scenario, the asset would be on the cache of the region too.
The region also has a database storing "prims" and "primitems". These
are not assets; they are the prims that are inworld at any given time.
The prims refer to assets (by UUID) that are stored on the asset
server. Which, as the previous sentence says, may be cached in memory
of the region.

<pre wrap="">Right. But what, exactly, are these servers doing? I guess I am trying
to get at more of the architectural details of what types of messages are
sent among servers (over the network and to the database(s)). For
example, there are the UGAIM servers in grid mode. Does the grid's "A"
server hold all of the assets on your region that you plugged into the
grid? Or does your region database (on the same computer as your
opensim.instance) take care of that?
