Chapter 3. Configuring the Hot Deployment System

By default, the FUSE ESB runtime scans a directory for bundles and JBI artifacts to automatically load. You can change the location of this folder and the interval at which the folder is scanned.

Default values

By default, the FUSE ESB runtime looks for a folder named deploy in the same folder from which the runtime was launched. For example if you launched the runtime from the root folder of your FUSE ESB installation, the hot deployment folder would be InstallDir/deploy.

The default scan interval is 500 milliseconds.

Specifying the hot deployment folder

You can specify the folder the FUSE ESB runtime monitors by setting the org.apache.servicemix.filemonitor.monitorDir property in the InstallDir/etc/config.properties configuration file. The value is the absolute path of the folder to monitor. If you set the value to /home/joe/deploy, the runtime will monitor a folder in Joe's home directory.

Controlling the scan interval

By default the FUSE ESB runtime scans a hot deployment folder every 500 milliseconds. To change the interval between scans of the hot deployment folders, you can change the org.apache.servicemix.filemonitor.scanInterval property in the InstallDir/etc/config.properties configuration file. The value is specified in milliseconds.

Example

Example 3.1 shows a configuration fragment that sets /home/smx/jbideploy as the hot deployment folder and sets the scan interval to 1 second.

Example 3.1. Configuring the Hot Deployment Folders

#
# FileMonitor properties

org.apache.servicemix.filemonitor.configDir        = ${servicemix.base}/etc
org.apache.servicemix.filemonitor.monitorDir       = ${servicemix.base}/deploy
org.apache.servicemix.filemonitor.generatedJarDir  = ${servicemix.base}/data/generated-bundles
org.apache.servicemix.filemonitor.scanInterval     = 1000
