activemq is an important open source Apache product, the application for the queue to play a significant role in promoting, when in actual project application, through the transmission queue data security is a primary issue to be considered in the activemq configuration provides three mater / slave backup mode:

First, memory backup, the system downtime, the original data is lost, the configuration file as follows:

master broker configuration file, without any particular place, is a standard broker configuration.

<Beans
xmlns = " http://www.springframework.org/schema/beans "
xmlns: xsi = " http://www.w3.org/2001/XMLSchema-instance "
xsi: schemaLocation = " http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd ">

<bean/>

<Broker brokerName = "Master" xmlns = " http://activemq.apache.org/schema/core ">
<transportConnectors>
<transportConnector uri="tcp://localhost:62001"/>
</ TransportConnectors>

</ Broker>

</ Beans>

slave broker configuration file, the red part is very important that the composition of a backup and a master of structure, under normal circumstances, the slave is in standby status, problems arise when the master, slave to working condition.

<Beans
xmlns = " http://www.springframework.org/schema/beans "
xmlns: xsi = " http://www.w3.org/2001/XMLSchema-instance "
xsi: schemaLocation = " http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd ">

<bean/>

<Broker brokerName = "slave" shutdownOnMasterFailure = "false" masterConnectorURI = "TCP: / / localhost: 62,001" xmlns = " http://activemq.apache.org/schema/core ">

<managementContext>
<managementContext createConnector="true" connectorPort ="1098"/>
</ ManagementContext>
<transportConnectors>
<transportConnector uri="tcp://localhost:62002"/>
</ TransportConnectors>

</ Broker>

</ Beans>

Second, use shared file configure master / slave structure:

1, by default, activemq start is to use file as the persistent storage, so when the two broker on the same server on startup,
Not the case with persistenceAdapter that file sharing type of mutual support mechanism.
2 can be configured to share files using persistenceAdapter location, when the broker starts a different server,
To form a mutual support mechanism.

Two profiles, except transportationConnector inconsistent, other things being equal:

<Beans
xmlns = " http://www.springframework.org/schema/beans "
xmlns: xsi = " http://www.w3.org/2001/XMLSchema-instance "
xsi: schemaLocation = " http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd ">

<bean/>

<Broker brokerName = "shared" xmlns = " http://activemq.apache.org/schema/core ">

<! -
In the default case, activemq start is to use file as the persistent storage, so when the two broker on the same server on startup,
Not the case with persistenceAdapter that file sharing type of mutual support mechanism.
Can be configured to share files using persistenceAdapter location, when the broker starts a different server,

->
<persistenceAdapter>
<journaledJDBC dataDirectory="/sharedFileSystem/broker"/>
</ PersistenceAdapter>

<transportConnectors>
<transportConnector uri="tcp://localhost:62001"/>
</ TransportConnectors>

</ Broker>

</ Beans>
Third, use of database backup and file backup mechanism is basically the same.
