| <section name="Sample 11: A Full Registry based Configuration, and Sharing Configuration Between Multiple Instances"> |
| <div class="xmlConf"><definitions xmlns="http://ws.apache.org/ns/synapse"> |
| |
| <registry provider="org.apache.synapse.registry.url.SimpleURLRegistry"> |
| <parameter name="root">file:./repository/conf/sample/resources/</parameter> |
| <parameter name="cachableDuration">15000</parameter> |
| </registry> |
| |
| </definitions></div> |
| <subsection name="Objective"> |
| <p> |
| Demonstrating the ability of Synapse to load the entire configuration from |
| a remote registry. This approach can also be used to share a single configuration |
| between multiple Synapse instances by pointing all the Synapse instances to the |
| same URL registry. |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2 |
| </li> |
| <li> |
| Start Synapse using the configuration numbered 11 (repository/conf/sample/synapse_sample_11.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 11<br/> |
| Windows: synapse.bat -sample 11 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| This example shows a full registry based Synapse configuration. This makes it |
| possible to easily start multiple instances of Synapse sharing a single configuration |
| in a clustered environment. The Synapse configuration of a given node hosting |
| Synapse simply points to the registry and looks up the actual configuration by |
| requesting the key 'synapse.xml'. |
| </p> |
| <p>(Note: Full registry based configuration is not dynamic atleast for the moment - |
| i.e. it is not reloading itself)</p> |
| <p> |
| Invoke the client as follows. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/</div> |
| <p> |
| Synapse will generate the following log output. |
| </p> |
| <div class="consoleOutput">[HttpServerWorker-1] INFO LogMediator - message = This is a dynamic Synapse configuration</div> |
| <p>The actual synapse.xml loaded from the registry is: </p> |
| <div class="xmlConf"><!-- a registry based Synapse configuration --> |
