imqConsumerFlowLimit
public static final java.lang.String imqConsumerFlowLimit
This property specifies the upper limit of the number of messages per consumer that will be delivered and buffered in the MQ client. When the number of JMS messages delivered to a consumer reaches this limit, message delivery for that consumer stops. Message delivery is only resumed when the number of unconsumed messages for that consumer drops below the value determined usingimqConsumerFlowThresholdproperty.When a consumer is created, JMS messages for that consumer will begin to flow to the connection on which the consumer has been established. When the number of messages delivered to the consumer reaches the limit set by
imqConsumerFlowLimit, delivery of messages is stopped. As messages are consumed, the number of unconsumed messages buffered in the MQ client drops.When the number of unconsumed messages drops below the number determined by using
imqConsumerFlowThreshold, as a percentage ofimqConsumerFlowLimit, MQ resumes delivery of messages to that consumer until the number of messages delivered to that consumer reaches the limit set byimqConsumerFlowLimit.Note that the actual value of the message flow limit used by MQ for each consumer is the lower of two values - the
imqConsumerFlowLimitset on the ConnectionFactory and theconsumerFlowLimitvalue set on the physical destination that the consumer is established on.The default value for this property is
1000- See Also:
imqConsumerFlowThreshold, Constant Field Values
-
imqConsumerFlowThreshold
public static final java.lang.String imqConsumerFlowThreshold
This property controls when JMS message delivery will resume to consumers that have had their message delivery stopped due to the number of messages buffered in the MQ client exceeding the limit set byimqConsumerFlowLimitand is expressed as a percentage ofimqConsumerFlowLimit.See the description for the

-
imqConsumerFlowLimitPrefetch
public static final java.lang.String imqConsumerFlowLimitPrefetch
When this property is set to false, there will be no prefetch next message (except the first message) from broker to a consumer, and consumer flow control propertiesimqConsumerFlowLimitandimqConsumerFlowThresholdwill be ignored. When it is set to true, the default, prefetch will take place as defined by consumer flow control properties.
-
imqConnectionFlowCount
public static final java.lang.String imqConnectionFlowCount
This property manages the number of JMS messages that will flow from the Sun MQ Message Service to the MQ Client between each 'resume flow' notification from the Client to the Message Service to receive additional JMS messages.If the count is set to
0then the Message Service will not restrict the number of JMS messages sent to the Client.After the Message Service has sent the number of JMS messages specified by this property, it will await a 'resume flow' notification from the Client before sending the next set of JMS messages. A non-zero value allows the Client to receive and process control messages from the Message Service even if there is a large number of JMS messages being held by the Message Service for delivery to this Client.
The MQ Client further has the ability to limit this JMS message flow using the property
imqConnectionFlowEnabledThe default value for this property is
100

imqConnectionFlowLimitEnabled
public static final java.lang.String imqConnectionFlowLimitEnabled
This property indicates whether the Sun MQ Client should limit the flow of JMS messages from the Sun MQ Message Service using the number of messages specified inimqConnectionFlowLimit.This property will only be active if the property

imqConnectionFlowLimit
public static final java.lang.String imqConnectionFlowLimit
This property specifies the number of uncomsumed JMS messages that a Sun MQ Client can hold, above which the MQ Client will refrain from sending a 'resume flow' notification to the Sun MQ Message Service. This property is active only when theimqFlowControlEnabledproperty is set totrueand theimqFlowControlCountproperty is set to a non-zero value.The MQ Client will notify the Sun MQ Message Service ('resume flow') and receive JMS message (in chunks determined by
imqFlowControlCount) until the number of received and uncomsumed JMS messages exceeds the value of this property. At this point, the Client will 'pause' until the JMS messages are consumed and when the unconsumed JMS message count drops below this value, the Client once again notifys the Message Service and the flow of JMS messages to the Client is resumed.The default value for this property is
1000
