Configure the host controller description

Use the Create Controller Description (SNA Host) (CRTCTLHOST) command to create the controller description. If you have already created a controller description for such functions as 3270 emulation or NRF, you must change the link type to *DLUR. Follow these steps:

  1. Retrieve the configuration description for the Dependent LU Requester (DLUR) controller description using the Retrieve Configuration Source (RTVCFGSRC) command.
  2. Edit the member to change the link type to *DLUR.
  3. Convert the source to a CL program.
  4. Create the CL program using the CRTCLPGM command.
  5. Delete the configuration using the DLTCTLD command.
  6. Call the CL program to create the new configuration.

An explanation of some of the fields on the Create Controller Description (SNA Host) (CRTCTLHOST) screen are as follows:

Local exchange identifier
Matches the ID block and ID number parameters from the PU definition on VTAM®.
Dependent PU name
Matches the name of the PU specified on the PU definition on VTAM.
Note:
If the local exchange identifier and the dependent PU name are specified, both must match the definitions on VTAM. If both parameter values do not match, the ACTPU will be rejected.

If the *DIAL value is specified for the INLCNN parameter, the primary DLUS name (PRIDLUS), and either the local exchange identifier (LCLEXCHID), or the dependent PU name (DEPPUNAME) must be specified.

Control point name and network identifier for the primary DLUS name
Matches the SSCP name and NETID parameters on the VTAM startup options.
