Using the OSPI ACB pool
When OSPI attempts to establish a session with a VTAM application, a VTAM ACB is required to represent the OSPI virtual terminal. If a specific ACB name is not requested, the OSPI ACB pool is searched for an available and usable ACB.
See the chapters that describe the OSPI Scripting facility and the IMFEXEC LOGON command in the MainView AutoOPERATOR Advanced Automation Guide for information about requesting a specific ACB.
Naming conventions
The pool consists of a group of ACBs named using the following conventions:
PPPPnnnn
where
PPPP | is the 4-character pool prefix |
nnnn | is a sequential number from 0000 to 9999 |
The default pool prefix is OSPI. You can specify a different prefix by using the OSPIPRFX parameter in BBPARM member AAOEXP00.
Note
The prefix must be four characters.
OSPI attempts to locate the first usable ACB beginning with OSPI0000. The search continues sequentially until a usable ACB is found or all OSPI ACBs have been exhausted.
