Defines default local IBM Session Manager node to which users are to be associated.
This common end-user parameter is applicable to these control statements: SYSTEM (see SYSTEM statement), PROFILE (see PROFILE statement), USER (see USER statement), and TERMINAL (see TERMINAL statement).
Default: system_acbname, as defined on the ACB parameter of the SYSTEM statement (see ACB).
The system_acbname identified as affinity_acbname is the IBM Session Manager system which receives the sign-on data. All sign-on data (for example, password, user name, and so on) is also passed, thereby enabling the sign-on to complete without further intervention from the user. The sign-on data is also passed to the E21 exit in the originating IBM Session Manager so that modifications may be made if required.
The affinity_acbname can be specified on the separate statements, and in addition by defining the Sign-on panel appropriately, using a defined input field (variable t_affinity) the affinity_acbname can be modified dynamically. See the PANEL statement in the Panels, Scripts and Variables manual.
