Specifies the number of messages that can be queued for this application program.
POAQLIM applies only to a program operator application program (AUTH=PPO or AUTH=SPO).
Code POAQLIM high enough so the limit will be reached only if there is an apparent error. A limit of five times the number of tasks using the program operator application (POA) times the number of lines in the longest expected message group should be enough to capture all necessary data without using excessive amounts of storage.
The limit for the PPO should be somewhat higher than the SPO to allow for unsolicited messages and PPOLOG messages.
It is also recommended that you increase VTAM® private storage by the sum of all the POAQLIM values specified in your system times 152 bytes, if possible. This is done by increasing the REGION parameter on the VTAM start procedure.
