The IFX Data Spaces Layer

A dbspace is a logical unit used to store databases, tables, logical log files and physical log files. It contains one or more chunks physically. The IfxDbSpace test, which is mapped to the IFX Data Spaces layer, monitors the dbspaces on the Informix server, and reports the size of each dbspace in terms of the number of chunks it constitutes, and the space usage and I/O activity on every dbspace.
