WSMQ-Warteschlangenlimit

Question

Gibt es eine Begrenzung für die Anzahl der Warteschlangen, die ich innerhalb einer einzelnen Verbindung und einer einzigen Sitzung öffnen kann? Ich kann derzeit 128 Warteschlangen öffnen und Nachrichten an sie senden. Wenn ich versuche, 129 ich die folgende Fehlermeldung erhalten zu öffnen ...

Dank

Answer 1

Dies wird gesteuert durch den MAXHANDS Attribut des WS-Managers.

Der Standardwert ist 256. Je nachdem, wie Sie auf die Warteschlangen zugreifen, können die Klassen jeweils zweimal geöffnet werden, was zu maximal 128 offenen Warteschlangen führt.

Sie können die Warteschlangengriffe in runmqsc mit dem Befehl DIS QSTATUS anzeigen.
