call attachment facility (CAF)
A DB2 attachment facility for application
programs that run in TSO or z/OS batch.
The CAF is an alternative to the DSN
command processor and provides greater
control over the execution environment.
Contrast with Recoverable Resource
Manager Services attachment facility.
call-level interface (CLI)
A callable application programming
interface (API) for database access, which
is an alternative to using embedded SQL.
cascade delete
A process by which DB2 enforces
referential constraints by deleting all
descendent rows of a deleted parent row.
CASE expression
An expression that is selected based on
the evaluation of one or more conditions.
cast function
A function that is used to convert
instances of a (source) data type into
instances of a different (target) data type.
castout
The DB2 process of writing changed
pages from a group buffer pool to disk.
castout owner
The DB2 member that is responsible for
casting out a particular page set or
partition.
catalog
In DB2, a collection of tables that contains
descriptions of objects such as tables,
views, and indexes.
catalog table
Any table in the DB2 catalog.
CCSID
See coded character set identifier.
CDB See communications database.
CDRA
See Character Data Representation
Architecture.
CEC See central processor complex.
central electronic complex (CEC)
See central processor complex.
central processor complex (CPC)
A physical collection of hardware that
consists of main storage, one or more
central processors, timers, and channels.

Application Programming Guide and Reference for Java
central processor (CP)
The part of the computer that contains the
sequencing and processing facilities for
instruction execution, initial program
load, and other machine operations.
CFRM See coupling facility resource
management.
CFRM policy
The allocation rules for a coupling facility
structure that are declared by a z/OS
administrator.
character conversion
The process of changing characters from
one encoding scheme to another.
Character Data Representation Architecture
(CDRA)
An architecture that is used to achieve
consistent representation, processing, and
interchange of string data.
character large object (CLOB)
| A character string data type that contains
a sequence of bytes that represent
|
characters (single-byte, multibyte, or both)
|
| that can range in size from 0 bytes to 2
GB, less 1 byte. In general, CLOB values
|
are used whenever a character string
|
| might exceed the limits of the VARCHAR
type.
|
character set
A defined set of characters.
character string
| A sequence of bytes that represent bit
data, single-byte characters, or a mixture
|
| of single-byte and multibyte characters.
| Character data can be further classified as
CHARACTER, VARCHAR, or CLOB.

check constraint
A user-defined constraint that specifies
the values that specific columns of a base
table can contain.
check integrity
The condition that exists when each row
in a table conforms to the check
constraints that are defined on that table.
check pending
A state of a table space or partition that
prevents its use by some utilities and by
some SQL statements because of rows
that violate referential constraints, check
constraints, or both.
