Determines whether the network ID of an attaching node
or the VTAM® network ID is used
for an adjacent nonnative node. Used to control how a nonnative node
can attach to VTAM.
Note: The
XNETALS option has changed in the way VTAM treats
PUs that send in non-native NETIDs in their XID. VTAM used to let the PU connect and treated
it as if it sent in the same NETID that VTAM started
with but that is no longer true. If
the NETID that the PU sent in its XID is not the same as the VTAM ID and XNETALS=NO or is defaulted,
IST680I will be issued.
- XNETALS=NO
- Indicates that the VTAM network
ID will be used to represent the connecting node's network ID.
During
connection:
- If the NETID operand is specified on the PU statement, then it
must specify VTAM's network ID.
- If the NETID operand is not coded on the PU statement, then VTAM's
network ID is assumed and the adjacent node's network ID is ignored.
During LU-LU session establishment:
- If the network ID for the originating LU is specified (during
connection time) and is not identical to VTAM's network ID, the session
will not be established.
- If the originating LU is not using a network qualified name, VTAM's
network ID is assumed and the session will be established.
Note: If the PU is a dependent LU server or requester,
nonnative network connection is not allowed if XNETALS=NO is specified
and the NETID operand is not coded.
- XNETALS=YES
- Indicates that the network ID of the adjacent PU will be used
for connection and session establishment.
During connection:
- If the NETID operand on the PU statement is coded, it will be
used as the PU's network ID. In this case, the network ID specified
on the PU statement must match the network ID specified by the attaching
node during connection processing.
- If the NETID operand is not specified on the PU statement, then
the network ID specified by the attaching node during connection processing
will be assumed.
During LU-LU session establishment:
- If the network ID for the originating LU is specified and does
not match the PU's network ID, the session will not be established.
- If the originating LU name is not a network qualified name, the
session will be established. VTAM will
qualify the LU's name with the attaching node's network ID.
Note: Providing that XNETALS=YES is coded, you can prohibit
nonnative network attachment for LU-LU sessions for a particular PU
by coding XNETALS=NO on the GROUP, LINE or PU statements.
