clone pair, clone pubset, clone session, clone unit
A clone unit is the copy of an (original) unit (logical disk in BS2000/OSD) at a
particular time (“Point-in-Time copy”). The TimeFinder/Clone component
creates this copy optionally as a complete copy or as a “snapshot”.
After they have been activated, the unit and clone unit are split; applications can
access both.
The unit and clone unit together form a clone pair. TimeFinder/Clone manages
this pair in what is known as a clone session.
If clone units exist for all units of a pubset, these clone units together form the
clone pubset.
Details of this are provided in the manual "

COBOL runtime system
Runtime system; sharable routines selected by the COBOL compiler

COBOL Subschema Directory (COSSD)
Provides the COBOL compiler with subschema information for compilation of

the DB application programs.
common memory
Shareable memory area used by several different tasks. In UDS/SQL, it always
consists of the common pool and the communication pool and, depending on the
application, the SSITAB pool (see SSITAB module) if CALL DML is used.
If UDS-D is used, it also consists of the distribution pool and the transfer pool.

Communication area of the independent DBH. Enables DBH modules to commu-
