Limit kolejki WSMQ

Question

Czy istnieje limit liczby kolejek, które mogę otworzyć w ramach pojedynczego połączenia i pojedynczej sesji? Mogę obecnie otworzyć 128 kolejek i wysyłać do nich wiadomości. Gdy próbuję otworzyć 129 pojawia się następujący błąd ...

Dzięki

Answer 1

ten jest kontrolowany przez atrybut menedżera kolejek za MAXHANDS.

Domyślną wartością jest 256. W zależności od tego, jak uzyskać dostęp do kolejki, zajęcia mogą być otwierając każdy dwa razy, w wyniku czego 128 max otwartych kolejek.

Można wyświetlić kolejkę uchwyty w runmqsc z komendy DIS QSTATUS.
