a number of both that are combined by

| set operators. Fullselect specifies a result
table. If a set operator is not used, the

result of the fullselect is the result of the

fully escaped mapping
A mapping from an SQL identifier to an
XML name when the SQL identifier is a
column name.
function
A mapping, which is embodied as a
program (the function body) that is
invocable by means of zero or more input
values (arguments) to a single value (the
result). See also aggregate function and
scalar function.
Functions can be user-defined, built-in, or
generated by DB2. (See also built-in
function, cast function, external function,
sourced function, SQL function, and
user-defined function.)
function definer
The authorization ID of the owner of the
schema of the function that is specified in
the CREATE FUNCTION statement.
function package
A package that results from binding the
DBRM for a function program.
function package owner
The authorization ID of the user who
binds the function program's DBRM into
a function package.
function signature
The logical concatenation of a fully
qualified function name with the data
types of all of its parameters.
GB Gigabyte. A value of (1 073 741 824 bytes).
GBP See group buffer pool.
GBP-dependent
The status of a page set or page set
partition that is dependent on the group
buffer pool. Either read/write interest is
active among DB2 subsystems for this
page set, or the page set has changed
pages in the group buffer pool that have
not yet been cast out to disk.
generalized trace facility (GTF)
A z/OS service program that records
significant system events such as I/O

interrupts, SVC interrupts, program
interrupts, or external interrupts.
generic resource name
A name that VTAM uses to represent
several application programs that provide
the same function in order to handle
session distribution and balancing in a
Sysplex environment.
geographic feature
|
| An object on the surface of the Earth
(such as a city or river), a space (such as a
|
| safety zone around a hazardous site), or
| an event that occurs at a location (such as
an auto accident that occurred at a
|
| particular intersection).
| geographic information system
A complex of objects, data, and
|
applications that is used to create and
|
| analyze spatial information about
geographic features.

getpage
An operation in which DB2 accesses a
data page.
global lock
A lock that provides concurrency control
within and among DB2 subsystems. The
scope of the lock is across all DB2
subsystems of a data sharing group.
global lock contention
Conflicts on locking requests between
different DB2 members of a data sharing
group when those members are trying to
serialize shared resources.
governor
See resource limit facility.
graphic string
A sequence of DBCS characters. Graphic

GRAPHIC, VARGRAPHIC, or DBCLOB.

See group buffer pool recovery pending.

gross lock
The shared, update, or exclusive mode locks
on a table, partition, or table space.
group buffer pool duplexing
The ability to write data to two instances
of a group buffer pool structure: a
primary group buffer pool and a
secondary group buffer pool. z/OS
publications refer to these instances as the
