[confluence]

Page Edited : qpid : System Properties System Properties has been edited by Martin Ritchie (Nov 27, 2008). (View changes) Content: Explanation of System properties used in Qpid This page documents the various System Properties that are currently used in the Qpid Java code base. Client Properties STRICT_AMQP Features disabled by STRICT_AMQP STRICT_AMQP_FATAL IMMEDIATE_PREFETCH amq.dynamicsaslregistrar.properties amqj.heartbeat.timeoutFactor amqj.tcpNoDelay amqj.sendBufferSize amqj.receiveBufferSize amqj.protocolprovider.class jboss.host jboss.port amqj.MaximumStateWait Management Properties security jmxconnector timeout Properties used in Examples archivepath Client Properties STRICT_AMQP Type : boolean Default : FALSE This forces the client to only send AMQP compliant frames. This will disable a number of JMS features. Features disabled by STRICT_AMQP Queue Browser Message Selectors Durable Subscriptions Session Recover may result in duplicate message delivery Destination validation, so no InvalidDestinationException will be thrown This is associated with property STRICT_AMQP_FATAL STRICT_AMQP_FATAL Type : boolean Default : FALSE This will cause any attempt to utilise an enhanced feature to throw and UnsupportedOperationException. When set to false then the exception will not occur but the feature will be disabled. e.g. The Queue Browser will always show no messages. Any message selector will be removed. IMMEDIATE_PREFETCH Type : boolean Default : FALSE The default with AMQP is to start prefetching messages. However, with certain 3rd party Java tools, such as Mule this can cause a problem. Mule will create a consumer but never consume from it so any any prefetched messages will be stuck until that session is closed. This property is used to re-instate the default AMQP behaviour. The default Qpid behaviour is to prevent prefetch occurring, by starting the connection Flow Controlled, until a request for a message is made on the consumer either via a receive() or setting a message listener. amq.dynamicsaslregistrar.properties Type : String Default: org/apache/qpid/client/security/DynamicSaslRegistrar.properties The name of the SASL configuration properties file. amqj.heartbeat.timeoutFactor Type : float Default : 2.0 The factor used to get the timeout from the delay between heartbeats amqj.tcpNoDelay Type : boolean Default : TRUE Disable Nagle's algorithm on the TCP connection. amqj.sendBufferSize Type : integer Default : 32768 This is the default buffer sized created by Mina. amqj.receiveBufferSize Type : integer Default : 32768 This is the default buffer sized created by Mina. amqj.protocolprovider.class Type : String Default : org.apache.qpid.server.protocol.AMQPFastProtocolHandler This specifies the default IoHandlerAdapter that represents the InVM broker. The IoHandlerAdapter must have a constructor that takes a single Integer that represents the InVM port number. jboss.host Used by the JBossConnectionFactoryInitialiser to specify the host to connect to perform JNDI lookups. jboss.port Used by the JBossConnectionFactoryInitialiser to specify the port to connect to perform JNDI lookups. amqj.MaximumStateWait Default : 30000 Used to set the maximum time the State Manager should wait before timing out a frame wait. Management Properties security Default: null String representing the Security level to be used to on the connection to the broker. The null default results in no security or PLAIN. When used with jmxconnector 'javax.management.remote.jmxmp.JMXMPConnector' a security value of 'CRAM-MD5' will result in all communication to the broker being encrypted. jmxconnector Default: null String representing the JMXConnector class used to perform the connection to the broker. The null default results in the standard JMX connector. Utilising 'javax.management.remote.jmxmp.JMXMPConnector' and security 'CRAM-MD5' will result in all communication to the broker being encrypted. timeout Default: 5000 Long value representing the milli seconds before connection to the broker should timeout. Properties used in Examples archivepath Used in : FileMessageDispatcher This properties specifies the directory to move payload file(s) to archive location as no error
