EMS event distributor. An EMS process that distributes event messages from event logs
to requesting management applications, to a collector on another node, or to printers,
devices, or files.
EMS message. A message generated internally by EMSPROC and identified by the
letter E when displayed on an OCS window.
EMS message prefix. The identifier that can precede a message from the EMS subsystem
when it is displayed on an OCS window. The prefix identifies the Tandem system
and/or the Guardian process that generated the message.
EMSP. See Event Management Service Process.
EMSPROC. A system-level NCL procedure that intercepts and processes messages from
the EMS subsystem.
enclosed element. An element inside another element.
enclosed MDO variable. A mapped data object variable inside another mapped data
object variable.
enclosing element. An element that contains one or more elements.
enclosing MDO variable. A mapped data object variable that contains one or more
mapped data object variables.
encoding rule. A rule used by Mapping Services to determine the order and
composition of the length field and the key field of a map header or element header.
Enscribe. A Tandem disk file access method that is supported by the Guardian file
system. Two types of Enscribe files are accessible from NCL: structured and
unstructured.
entry-sequenced UDB. A structured Enscribe user database consisting of variable-length
records that are always appended to the file in the order in which they are presented.
The records in an entry-sequenced user database are arranged physically and logically
in the order in which they are added to the file.
enumerated MDO variable. A mapped data object variable that stores raw data
representing a symbolic name.
environment. An area in which NonStop NET/MASTER MS users, NonStop
NET/MASTER MS commands, and NCL processes operate. An environment is
designed to limit the default activities of these users, commands, and processes.
environmental profile. A profile that determines what a user can do in an environment.
The user can change certain aspects of this profile by using the NonStop
NET/MASTER MS PROFILE command. An RMS ruleset can contain an
environmental profile record that a message handler can use to set up its execution
environment.
equate. A symbol defined to correspond to some text by the EQUATE command. The
text is normally one or more NonStop NET/MASTER MS commands. There are two
types of equates: local and global.
