Object Type - *USRIDX

A user index is an object that allows search functions for data in the
index and automatically sorts data based on the value of the data.  User
indexes are permanent objects with a maximum size of 4GB, and are great
for indexing user data that does not need to be stored in DB2/400 files
(or where you don't want performance impacted by having to access
database because everything you need is in the key).  You may want to
review the User Indexes APIs - Introduction found in the System API
Reference.

A user space is an object that consists of a collection of bytes used
for storing program defined data.  User spaces are permanent objects
with a maximum size of 16MB, and are great for high performance (possibly
shared) access to user-defined data.  You may want to review the User
Space APIs - Introduction found in the System API Reference.

The two objects have virtually nothing in common other than being two
object types that developers can use to meet their various application
requirements.
