Requesting that VTAM Verify Partner LUs
When your installation codes a VTAM® APPL
statement to define an LU to VTAM,
you must specify whether you want VTAM to
verify the identity of partner LUs that attempt to establish sessions
with the LU. To do so, set the APPL statement's VERIFY keyword to
one of the following values:
- Value
- Meaning
- NONE
- VTAM should not verify partner LUs (the default)
- OPTIONAL
- VTAM should verify those partner LUs that have defined LU-to-LU passwords (session keys), as described in z/OS V2R1.0 Communications Server: SNA Resource Definition Reference
- REQUIRED
- VTAM should verify every partner LU.
If you request verification, VTAM verifies partner LUs by means of an associated session key. You can use the RACF® APPCLU class to specify the session key for each LU, as described in Defining LU-to-LU Session Keys.
