Duplicates can happen for non-persistent messages during failover. gcInactiveDestinations false Garbage collect inactive destinations. inactiveTimoutBeforeGC 5000 The timeout (in ms) after which a destination is considered inactive. includeBodyForAdvisory false Includes the body of the original message that triggered the advisory as part of the dataStructure field in the advisory message (where applicable). Normally the message body is cleared. maxBrowsePageSize 400 The maximum number of messages to page in from the store at one time for a browser. maxDestinations -1 (v5.12) If 0 or greater, sets the maximum number of destinations that can be created. This parameter is intended to limit the number of hierarchical destinations that can be created under a wildcard destination. maxPageSize 200 The maximum number of messages to page in from the store at one time. Increase this value to improve performance for queue destination's that contain grouped messages that are consumed by multiple concurrent consumers. memoryLimit n/a The memory limit (in bytes) of the destination's cursor. This memory limit is subordinate to the system level memory limit, as specified by the / attribute. There is no default for this value; it simply acts as a child to the overall broker memory until the broker memory is exhausted. Note: when this limit is specified the destination's cursorMemoryHighWaterMark will be applied against it and not the /> memory limit. minimumMessageSize 1024 For non-serialized messages (embedded broker) - the assumed size of the message used for memory usage calculation. Serialized messages use the serialized size as the basis for the memory calculation. prioritizedMessages false Persist message priority information. producerFlowControl true If true the broker will throttle (flow-control) the producer. Throttling is achieved either by withholding the producer's ACK or by raising a javax.jms.ResourceAllocationException (that's propagated back to the client) when local resources e.g., memory and/or storage, have been exhausted. If false excess messages will be written to the message store to prevent memory exhaustion. However, when the message store reaches capacity the producer will be throttled until resources are freed. slowConsumerStrategy null Sets the strategy for handling slow consumers. See AbortSlowConsumerStrategy. storeUsageHighWaterMark 100 The percentage (%) threshold of the / store limit which when exceeded causes a send to block. useCache true If true persistent messages are cached for fast retrieval from store. usePrefetchExtension true The prefetch extension is used when a message is delivered but not ACK'ed, such that the broker can dispatch another message, e.g., prefetch == 0, the idea being that there will always be prefetch number of messages pending. It also allows a transaction batch to exceed the prefetch value. sendFailIfNoSpace false (v5.16.0) If true, will cause a send to fail with a javax.jms.ResourceAllocationException when the destination has reached is resource limits (memory or storage) sendFailIfNoSpaceAfterTimeout 0 (v5.16.0) if > 0, will cause a send to fail with a javax.jms.ResourceAllocationException when the destination resource limits (memory or storage) remain exhausted for the configured duration in milliseconds Additional properties for a Queue ...
