Defines the name of the ACB by which IBM Session Manager and VTAM communicate with one another. The name must also be defined on the appropriate VTAM APPL macro.
This parameter is applicable to the SYSTEM control statement (see SYSTEM statement).
If 0 is specified then IBM Session Manager makes no attempt to open an ACB. A VTAM acbname can subsequently be specified on an ACB parameter in a different configuration file and this file can then be loaded using the UPDATE CONFIG command, IBM Session Manager then attempts to open this new ACB.
If the system_acbname becomes inactive, IBM Session Manager continues to process and attempts to re-open the ACB every two minutes. In this circumstance, when the ACB is not open, an UPDATE command can be issued specifying a configuration file with a new acbname on the ACB parameter. IBM Session Manager then attempts to open this new ACB.
If the system_acbname has been opened by another application, then IBM Session Manager continues to process, but without the terminal acb. This means that users will be unable to continue. A new acbname can be specified using the UPDATE command as in the previous two examples.
