22.3. Paging Mode
As soon as messages delivered to an address exceed the configured size, that address alone goes into page mode.
Note
Paging is done individually per address. Configuring a max-size-bytes for an address means each matching address will have a maximum size specified. Please note it does not mean that the total overall size of all matching addresses is limited to max-size-bytes.
22.3.1. Configuration
Configuration is done in the address settings, in
<JBOSS_HOME>/jboss-as/server/<PROFILE>/deploy/hornetq/hornetq-configuration.xml.
<address-settings>
<address-setting match="jms.someaddress">
<max-size-bytes>104857600</max-size-bytes>
<page-size-bytes>10485760</page-size-bytes>
<address-full-policy>PAGE</address-full-policy>
</address-setting>
</address-settings>
