EBCDIC
Extended binary coded decimal
interchange code. An encoding scheme
that is used to represent character data in
the z/OS, VM, VSE, and iSeries
environments. Contrast with ASCII and
Unicode.
embedded SQL
SQL statements that are coded within an
application program. See static SQL.
enabling-new-function mode* (ENFM*)
A transitional stage of the
version-to-version migration process that
applies to a DB2 subsystem or data
sharing group that was in new-function
mode (NFM) at one time. When in
enabling-new-function mode*, a DB2
subsystem or data sharing group is
preparing to use the new functions of the
new version but cannot yet use them. A
data sharing group that is in
enabling-new-function mode* cannot
coexist with members that are still at the
prior version level. Fallback to a prior
version is not supported. Contrast with
compatibility mode, compatibility mode*,
enabling-new-function mode, and
new-function mode.
enabling-new-function mode (ENFM)
A transitional stage of the
version-to-version migration process
during which the DB2 subsystem or data
sharing group is preparing to use the new
functions of the new version. When in
enabling-new-function mode, a DB2 data
sharing group cannot coexist with
members that are still at the prior version
level. Fallback to a prior version is not
supported, and new functions of the new
version are not available for use in
enabling-new-function mode. Contrast
with compatibility mode, compatibility
mode*, enabling-new-function mode*, and
new-function mode.
enclave
In Language Environment, an
independent collection of routines, one of
which is designated as the main routine.
An enclave is similar to a program or run
unit. See also WLM enclave.
encoding scheme
A set of rules to represent character data
(ASCII, EBCDIC, or Unicode).
ENFM See enabling-new-function mode.
ENFM*
See enabling-new-function mode*.
entity A person, object, or concept about which
information is stored. In a relational
database, entities are represented as
tables. A database includes information
about the entities in an organization or
business, and their relationships to each
other.
enumerated list
A set of DB2 objects that are defined with
a LISTDEF utility control statement in
which pattern-matching characters (*, %;,
_, or ?) are not used.
environment
A collection of names of logical and
physical resources that are used to
support the performance of a function.
environment handle
A handle that identifies the global context
for database access. All data that is
pertinent to all objects in the environment
is associated with this handle.
equijoin
A join operation in which the
join-condition has the form expression =
expression. See also join, full outer join,
inner join, left outer join, outer join, and
right outer join.
error page range
A range of pages that are considered to be
physically damaged. DB2 does not allow
users to access any pages that fall within
this range.
escape character
The symbol, a double quotation (″) for
example, that is used to enclose an SQL
delimited identifier.
exabyte
A unit of measure for processor, real and
virtual storage capacities, and channel
volume that has a value of 1 152 921 504
606 846 976 bytes or 2
60
.
exception
An SQL operation that involves the
EXCEPT set operator, which combines
two result tables. The result of an
exception operation consists of all of the
rows that are in only one of the result
tables.
