WSMQ Queue Limit

Question

¿Existe un límite en la cantidad de colas que puedo tener abiertas dentro de una sola conexión y sesión única? Actualmente puedo abrir 128 colas y enviarles mensajes. Si intento abrir un 129 me sale el siguiente error ...

Gracias

Answer 1

Esto es controlado por el atributo del gestor de colas MAXHANDS.

El valor predeterminado es 256. Dependiendo de cómo acceda a las colas, las clases pueden abrir cada una dos veces, lo que da como resultado 128 colas máximas abiertas.

Puede visualizar los controladores de cola en runmqsc con el comando DIS QSTATUS.
