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
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.
