Identifies the name of the primary logical unit that this logical unit will automatically log on to as a secondary logical unit when this logical unit is activated. The name you specify can also be a USERVAR that will be resolved into its current value before being used to establish or redrive the session with the controlling primary logical unit.
For independent logical units, the LOGAPPL operand establishes a session with the primary logical unit designated in the LOGAPPL operand if a session does not currently exist with this logical unit. The session is established regardless of whether sessions with other logical units exist. The LOGAPPL operand cannot contain the name of an independent logical unit because independent logical units cannot be the controlling logical units for an automatic logon session.
Automatic logon LU-LU sessions are not redriven after CP-CP outages even though the CP-CP sessions might redrive.
You can specify a network-qualified name for LOGAPPL. You cannot specify an LUALIAS name for LOGAPPL.
For more information on establishing sessions, see the z/OS Communications Server: SNA Network Implementation Guide.
