Specify a Default Destination

The destination of an APPC transaction request can be specified by using the &APPC ALLOCATE verb or in the TCT definition. If no destination is specified on the &APPC ALLOCATE verb, the destination in the TCT is used. If no destination is specified on the &APPC ALLOCATE verb or in the TCT, a default destination of ENV=CURRENT is assumed.

If the same destination always services a transaction request, you can specify a default destination in the TCT definition. To specify a default destination in a TCT definition, specify one of the following on the DEFTRANS command:

• A link name using the LINK operand
• An LU name using the LUNAME operand
• A product domain ID, using the DOMAIN operand
• The NCL environment using the ENV operand (for local conversations)

Example: Specify a Default Destination

To define an APPC link with a transaction ID of DBQUERY, a TPN of DB01, and a link name of NMB, enter the following command:

DEFTRANS TRANSID=DBQUERY TPN=DB01 LINK=NMB

Note: For more information about the options that can be specified in a TCT, see the description of the DEFTRANS command in the online help.
