Using Dynamic LU Support to Define SNA Resources

You can use dynamic LU support to create resource definitions for remote LU resources and ALS resources.

Defining Remote LU Resources

Remote LU resources can log on to the TPF system without first being defined using the OSTG program. Instead, when a new remote LU resource tries to log on to an application in the TPF system, the TPF system automatically creates a resource definition and a 381-byte pool file NCB record for that remote LU resource, which allows the session to be started.

Important Considerations

Defining Remote ALS Resources

If the TPF system is running in APPN mode, ALS links can be activated without first defining the ALS resource to the TPF system using the OSTG program. When an ALS resource that was not previously known to the TPF system tries to activate the PU 2.1 link, the TPF system automatically creates a resource definition for that ALS resource, which allows the link to be activated.

Note:
The TPF system does not create an NCB record for ALS resources that are defined using dynamic LU support.

Restrictions

You cannot use dynamic LU support to define ALS resources if the TPF system is running in LEN mode.

Important Considerations

Resource definitions that are created using dynamic LU support are removed from the TPF system if a fresh load is performed.
