NQNMODE
statements: | GROUP, CDRSC |
dependencies: | valid only for resources defined under the NETWORK statement |
Indicates whether VTAM® defines the cross-network resource by its non-network-qualified name and its network-qualified name or by only its network-qualified name.
NQNMODE is valid only for cross-domain and cross-network resources that are defined under a NETWORK definition statement. Same-network CDRSCs are always considered to be defined with NQNMODE=NAME because these resources are always identified by their non-network-qualified names.
When NQNMODE is specified on the CDRSC definition statement, it overrides the value specified on the NQNMODE start option. Dynamic CDRSCs are controlled by the NQNMODE start option.
- NQNMODE=NAME
- The cross-network resource is defined by both its network-qualified
name and its non-network-qualified name. The same-network CDRSC is
always considered to be defined using NQNMODE=NAME because it is always
identified by its non-network-qualified name. This is the mode in
which pre-V4 releases of VTAM operate.
If a CDRSC is defined using NQNMODE=NAME (either by definition or start option), then no other resource can be defined to that host by the same non-network-qualified name.
- NQNMODE=NQNAME
- The cross-network resources is defined by its network-qualified
name and is not defined to this host by its non-network-qualified
name.
If you have duplicate names in your SNA-interconnected networks and want to avoid using other forms of alias name translation, you can specify (either by definition or start option) NQNMODE=NQNAME.
Type of CDRSC | CDRSC or start option | NQNMODE=NAME | NQNMODE=NQNAME |
---|---|---|---|
Predefined CDRSCs with NETID | CDRSC and start option (CDRSC overrides start option) | Cross-network resources defined by their non-network-qualified names and their network qualified names | Cross-network resources defined by their network-qualified names only |
Predefined CDRSCs without NETID | Neither (NQNMODE not applicable) | ||
Dynamic CDRSCs defined by their network-qualified names and their implied alias names (consisting of their non-network-qualified names and the network identifiers of their session partners). | Start option | CDRSCs defined by their non-network-qualified names and their network qualified names | CDRSCs defined by their network-qualified names |
Same-network CDRSCs and native independent LUs | Neither (NQNMODE not applicable) | Has no effect. Network-qualified name and non-network-qualified name are considered equivalent. | Has no effect. Network-qualified name and non-network-qualified name are considered equivalent. |
Nonnatively attached independent LUs defined as LUs with LOCADDR=0 coded | Start option | CDRSCs defined by their non-network-qualified names and their network qualified names | CDRSCs defined by their network-qualified names only |
Nonnatively attached independent LUs defined as CDRSCs | CDRSC and start option (CDRSC overrides start option) | CDRSCs defined by their non-network-qualified names and their network qualified names | CDRSCs defined by their network-qualified names only |
