name is required. It specifies
a minor node name for this application program, as does the ACBNAME
operand. This name, when used with the network identifier (NETID as
specified on the VTAM® START
command) is the network-qualified name of the application program,
in the form of
netid.name. This name is
sometimes called the real name to distinguish it from an alias or
USERVAR name. This name must be unique in the following situations:
- Within the domain in which the application resides
- Throughout the network if the application program participates
in cross-domain sessions
- Throughout all networks if the application program participates
in cross-network sessions, unless network-qualified names, LUALIAS,
or the alias translation function is used.
name must follow the rules for
naming application programs as described in the
z/OS Communications Server: SNA Network Implementation
Guide and can include the following wildcard characters:
- Asterisk (*)
- Represents 0 or more unspecified characters. An asterisk can be
used as the second to eighth character.
- Question mark (?)
- Represents a single unspecified character. A question mark can
be used as the first to eighth character.
A logical unit can request a session with an application
by using one of the following names associated with the application:
- An application program network name, the name operand
(from any domain in the network)
- The ACB name associated with the application (from within the
same domain).
A logical unit using the application program’s network
name (the
name operand on the APPL definition
statement) can establish a session with the application program from
any domain in the network. A logical unit using the ACB name to establish
a session with an application program must be in the same domain.
If you do not code ACBNAME, this name must be the same
as the name in the APPLID operand of the ACB macroinstruction for
this application program. z/OS Communications Server: SNA Programming describes the ACB macroinstruction.
Note: If you duplicate names for application program minor
nodes, it is not advisable to register more than one of the duplicate
names at a time. If there are duplicate application program major
node names and more than one is registered, you will receive messages
about the duplication.
